SEO 2026 – Topdog’s Complete Guide to Successful Search Engine Optimisation

Welcome to Topdog’s SEO guide. Whether you’re an amateur, a manager or department head, or an experienced SEO specialist, you’ll find the answers to your questions here. If this article (or the content we link to) doesn’t answer your question, you’re welcome to get in touch.

What is SEO?

Search Engine Optimisation (SEO) is the process of improving a website technically, in terms of content, and structurally in order to increase its visibility in organic search results on Google.

The goal of SEO is to generate relevant traffic, attract potential customers and create long-term commercial value — without paying for advertising.

What does SEO optimisation involve in practice?

SEO optimisation covers four main areas that together determine how highly a website ranks in search engines. Each area contributes to greater visibility and a better user experience.

• Content: Relevant, search-intent-aligned copy that answers the user’s questions.
• Technical: Fast loading times, correct indexing and mobile responsiveness.
• User experience (UX): Clear structure, easy-to-navigate pages and high readability.
• External links: Authoritative links that strengthen the site’s credibility.

By improving these areas, you strengthen both the user experience and Google’s search results — leading to greater organic visibility, traffic and conversions.

Why is SEO important?

SEO is a central part of digital marketing because organic search often accounts for a large share of a website’s traffic. In Sweden, tens of millions of searches are made on Google every day – and many of these have clear purchase intent. With search engine optimisation, you can reach users at the precise moment they are actively searching for your products or services.

Drawing on actual data, Christian explains in this video exactly how important SEO is and why it has become so.

SEO is cost-effective marketing

SEO is one of the most cost-effective marketing channels available. Unlike advertising, your content only appears when users are genuinely interested, which makes communication far more targeted and efficient.

SEO strengthens the customer journey

SEO also plays a key role in the customer journey, because purchases are usually preceded by some form of research — typically on Google. By creating content that answers users’ questions at each stage — from initial research through to purchase — you build trust and guide them all the way to conversion. SEO can give you touchpoints at every step of the customer journey.

SEO can provide touchpoints at every stage of the customer journey.

SEO is a long-term investment

Unlike ads, which only deliver results for as long as you’re paying for them, search engine optimisation builds a website that continually generates organic traffic, conversions and commercial value over time.

The biggest difference between SEO and paid advertising is that advertising is a cost, whilst SEO is an investment. SEO is considered an investment because it improves the website across four areas — technical, user experience, content and links. The resources you put into those improvements are converted, in turn, into rankings, traffic and conversions. The result is a website that both users and search engines like. We tend to say that successful search engine optimisation is paid for in advance.

SEO makes your business more efficient

SEO isn’t only about driving organic traffic. Good content can also reduce friction in the customer journey and take pressure off other parts of the business. If customers frequently ask sales, support or customer service the same questions, SEO content can answer those questions before the contact ever happens. In this way, search engine optimisation becomes both a marketing channel and a way to make your communications, support and sales more efficient.

SEO is the foundation for visibility in AI models

AI-powered search services and language models draw heavily on content that is already visible and credible on the web. That means classic SEO factors — relevant content, clear structure, authority and links — also influence whether your content gets used, cited or recommended by AI systems.

By working systematically with search engine optimisation, you increase the likelihood that your brand and your information appear not just in Google’s search results, but also in AI-generated answers — which is becoming increasingly important as search behaviour shifts.

Further benefits of SEO

• Increased trust: High rankings in Google strengthen your brand.
• Better conversion: Relevant organic traffic typically leads to more business.
• Cost efficiency: Reduced reliance on paid advertising.
• Competitive advantage: You appear ahead of your competitors.

How do you succeed with SEO?

To succeed with search engine optimisation, you need to:

• Have a clear strategy based on business objectives
• Match the right search intent
• Build a logical site structure
• Create better content than your competitors
• Ensure technical performance
• Build authority through links and brand
• Work in a data-driven, continuous way

At its core, SEO is about helping both users and Google understand and choose your website. Succeeding therefore takes a combination of strategy, quality and persistence.

The first step is to start from the commercial side of things. Search engine optimisation shouldn’t just drive traffic — it should drive the right traffic, users with the potential to become customers. That means identifying which searches actually create value, and prioritising those.

A decisive factor is understanding search intent. What does the user want when they make a search? Your content has to match that exactly, otherwise it won’t rank — regardless of how good it is in other respects.

Structure also plays a central role. A clear site structure, well-thought-out internal linking and the right page types make it easier for both Google and users to navigate and understand your content.

The content itself needs to be better than your competitors’. That means more relevant, more comprehensive, and clearer in answering the user’s questions. At the same time, it needs to signal credibility and expertise.

The technical foundation has to work. Google needs to be able to crawl and index the page; it has to be fast and work well on mobile. Technical performance is rarely what decides who wins — but problems here can stop every other SEO effort in its tracks.

Competing in the search results also requires authority. That’s built through external links, brand awareness and other trust signals that show your site deserves to be promoted.

Finally, search engine optimisation is ongoing work. You need to follow up on results, analyse the data, and improve content and structure over time. It’s rarely a single initiative that decides the outcome — it’s the sum of many improvements. SEO takes time, but done right it creates a stable, long-term source of organic traffic, business and growth.

SEO requires the right organisation

SEO is rarely an isolated activity. To succeed, the work usually needs to be embedded in the organisation and involve several functions — marketing, technical and content. That means SEO-related decisions need to be made by the leadership team, resources need to be prioritised, and different teams need to be working towards the same goal.

Many SEO initiatives fail not for lack of knowledge, but for lack of coordination and execution. That’s why it’s important to treat search engine optimisation as an organisation-wide project — not just a marketing initiative.

SEO is complex, and getting the priorities right from the start matters. We’ll help you identify what actually moves the needle — and what you can safely ignore.

Core areas — the heart of SEO

To succeed with search engine optimisation, you need to work across three central areas that together determine how well your website performs in the search results.

On-page SEO is about content, structure and how well you meet the user’s needs.

Technical SEO ensures the site runs correctly, is fast, and can be indexed by Google.

Off-page SEO and link-building builds your authority and credibility through external signals.

Together, these form the foundation of all successful search engine optimisation.

On-page SEO

On-page SEO means, in short: search engine optimisation carried out on your own website. It’s about optimising the site so that it’s relevant, useful and clear for both users and Google. The goal is to help the visitor find the right information, understand the content and take the next step — whilst making it easy for Google to interpret and rank the page.

The most important parts of on-page SEO are:

• Keyword research
• Site structure
• Content optimisation
• Internal linking

Together, these create a foundation where the right content reaches the right user at the right moment.

Keyword research maps user behaviour

Keyword research is the foundation of all search engine optimisation. It’s about understanding what users actually search for, how they phrase their queries, and what needs sit behind those searches. The results are used to:

• identify business-critical searches
• prioritise content
• build a logical site structure

A good keyword research process doesn’t just focus on volume — it focuses on search intent and commercial value.

Site structure creates coherence

Your site structure determines how your content hangs together. A clear structure helps both users and Google understand which pages are most important and how different topics relate to one another. It’s not primarily about how URLs are structured — it’s about how the site’s various topics are connected.

“How to structure content for SEO success”

An effective structure:

• organises content into clear topic clusters
• avoids duplicated or thin content
• makes navigation easy

The right structure is essential for being able to scale your SEO work and build authority within a topic area.

Content optimisation helps you meet user needs

Content optimisation is about creating content that answers the user’s question better than your competitors. To succeed, you need to:

• match the right search intent
• create content that is more complete, clearer and more relevant than your competitors’
• optimise title, headings and metadata

Good SEO content isn’t just text — it can also include images, video, tables and other elements that improve understanding. Content marketing and search engine optimisation go hand in hand, and SEO content is also a process in itself: create, measure, improve.

Internal linking aids navigation and discovery

Internal linking ties your website together and reinforces your structure. By linking between relevant pages, you help both users and Google to navigate and understand the content. Internal links:

• show which pages are most important
• help Google index content
• distribute authority across the site
• improve user experience

Thoughtful internal linking is one of the most underrated — yet most effective — areas of search engine optimisation.

It’s the whole that lifts the site

On-page SEO isn’t about individual optimisations — it’s about the whole. When content, structure and links work together, you build a website that both ranks better and converts better.

Technical SEO

Technical SEO is about making sure your website works correctly, is fast, and can be understood by search engines. Unlike on-page SEO, technical SEO doesn’t focus on the content itself, but on the technical infrastructure that makes the content accessible and indexable.

The goal is to make it as easy as possible for Google to crawl, understand and rank your website — whilst also improving the user experience.

Fundamental technical optimisation

Technical search engine optimisation covers a number of important areas:

• Indexing and crawling: Making sure the right pages can be found and indexed by Google.
• URL structure: Clear, readable and logical URLs.
• Duplicate content: Handled with canonical tags, redirects and noindex.
• Metadata: Correct handling of titles, meta descriptions and headings.
• XML sitemap: Helps search engines find content.
• Internal technical rules: Handling of filters, parameters and pagination.
• Structured data: Schema markup to improve understanding and organic visibility.
• Server and response codes: Correct status codes (200, 301, 404, etc.).

An important part of technical SEO is also automation, especially for larger sites. By automating metadata and URL rules, for example, you can scale your SEO work efficiently.

Core Web Vitals

Core Web Vitals are Google’s measures of user experience tied to performance. They focus on three areas:

• Load time (LCP) – how quickly the main content appears
• Interactivity (INP) – how quickly the page responds to user interaction
• Visual stability (CLS) – whether content “jumps” as the page loads

Good scores improve both rankings and user experience. The work usually involves optimising images, scripts, rendering and server performance.

Mobile-friendliness

Google uses mobile-first indexing, meaning it’s the mobile version of your site that gets evaluated first. A mobile-friendly site should:

• work without issues on smaller screens
• have readable text and tappable elements
• load quickly even on weaker connections
• avoid intrusive elements (such as pop-ups)

A poor mobile experience can directly affect both rankings and conversions.

Performance and stability

Beyond Core Web Vitals, general performance matters too. Slow websites lead to a worse user experience and lower conversion. Key factors:

• fast server and hosting
• optimised images and assets
• minimising unnecessary code
• caching and CDN

Way of working and implementation

Technical search engine optimisation is rarely a one-off effort — it requires a structured way of working. Problems need to be broken down, prioritised and implemented in partnership with developers. To succeed, you need:

• clear requirement specifications
• prioritisation based on business value
• continuous follow-up

Technical SEO creates the conditions for every other SEO effort to work. If the technical side is broken, it doesn’t matter how good the content is — it still won’t perform at its best.

Off-page SEO and link-building

Off-page SEO is about all the external signals that influence how Google and other systems perceive your website. Where on-page SEO is about what you say on your own site, off-page SEO is about what others say about you.

The aim is to build authority, credibility and demand — factors that often decide who ranks highest in competitive search results.

Off-page SEO is also becoming increasingly important in AI-powered search services, where brand mentions and context can carry as much weight as links.

Link strategy

A well-thought-out link strategy is the foundation of successful off-page SEO. It’s about systematically building relevant, high-quality links that strengthen your site’s authority. Key principles:

• quality over quantity
• relevance over volume
• the long view over quick wins

An effective strategy connects link-building to the rest of your marketing — PR, content and brand-building.

Link-building

Link-building means getting other websites to link to yours. These links act as recommendations and are one of Google’s most important ranking factors. To succeed, you need:

• links from credible, relevant sites
• content that is worth linking to
• continuous work over time

It’s also important to recognise that search engine optimisation is competitive — your competitors are building links too, which makes link-building an ongoing process.

Digital PR and mentions

PR is one of the most effective ways to build both links and brand. By appearing in the media and in relevant contexts, you can generate strong external signals that influence both SEO and your business.

In addition to links, mentions without a link are also becoming increasingly important — especially in the AI context, where brands are understood within a wider frame of reference.

Brand and authority

Strong brands have a clear advantage in the search results. Users click more often on what they recognise, and Google interprets that as a quality signal. Brand-building contributes to:

• higher click-through rate (CTR)
• more natural links
• increased credibility

SEO and branding are closely linked — the stronger the brand, the easier it is to rank.

Forums, social platforms and communities

Platforms like Reddit, Quora and industry forums are important for building digital visibility and trust. By taking part in discussions and sharing your knowledge, you can:

• reach new audiences
• strengthen your role as an expert
• generate traffic and indirect SEO signals

These platforms are also used extensively by AI systems as data sources.

Customer reviews

Reviews act as user-generated recommendations and are an important credibility signal. They contribute to:

• greater legitimacy
• better organic visibility, especially locally
• more content tied to your brand

Reviews help both Google and users understand what you offer and how you’re perceived.

More off-page areas

The common thread across off-page SEO is that every activity builds digital visibility, mentions and demand. That includes things like social media, influencer marketing, YouTube SEO, App Store Optimisation (ASO), affiliate marketing, partnerships, events, guest posts and industry listings — all of which indirectly strengthen search engine optimisation.

Trust is everything

Off-page SEO is, at its heart, about trust. The more relevant players that link to, mention or interact with your brand — the greater the likelihood you’ll rank highly.

Quality and ranking signals — decisive for organic visibility

As search engine optimisation has matured, Google’s focus has shifted from what you say to whether you deserve to rank. Good content and good links are no longer enough. To reach the top — especially in competitive segments — you have to show that you’re a credible, relevant and better choice than the alternatives.

This is where E-E-A-T and UX/SXO become decisive. They act as a quality check sitting on top of every other piece of search engine optimisation.

E-E-A-T and authority

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is Google’s framework for deciding who they’re willing to show at the top. In practice, E-E-A-T answers the question: why should Google trust you — rather than your competitors?

This becomes especially decisive when many pages have similar content, when competition is high, or when the topic demands credibility. To rank, you need to demonstrate:

• Experience – you have actually done what you’re writing about
• Expertise – the content is accurate, deep and insightful
• Authoritativeness – others reference you (links, mentions)
• Trustworthiness – you’re a legitimate, transparent actor

In many cases, it’s E-E-A-T that decides who makes the top three — not content or technical SEO.

This is especially true in so-called YMYL (Your Money or Your Life) niches: health and medicine, finance and economics, law, safety and risk, major purchasing decisions, education and careers, and children and family.

If you operate in one of these areas, E-E-A-T isn’t just important — it’s often decisive in whether you can rank at all. Google sets a higher bar for credibility when content can affect people’s health, finances or life decisions.

UX and conversion (SXO)

SXO (Search Experience Optimisation) is about the fact that you don’t just need to rank — you need to win the user too. Google continually analyses how users interact with the search results. If your page doesn’t deliver a good experience, you’ll lose positions over time.

That means SEO and UX are now directly linked. Strong UX means:

• the user quickly understands they’ve come to the right place
• the content is easy to scan and absorb
• the page guides the user towards a goal
• nothing creates friction or hesitation

The effect is twofold: better UX produces stronger ranking signals and higher conversion. This is where many SEO initiatives fall short — they create organic traffic, but fail to convert it.

Quality signals are the tiebreaker

When several players have good-enough search engine optimisation, it’s the quality signals that decide who wins.

• E-E-A-T decides whether you deserve to rank.
• UX decides whether you keep that position and turn it into business.

It’s no longer enough to be relevant — you have to be the best and most credible option.

AI and SEO

AI is changing how people search and how content is discovered. Alongside traditional search engines, AI services like ChatGPT, Google AI Overview and other language models are now used to find answers, compare options and make decisions.

That means search engine optimisation is no longer just about ranking in Google — it’s also about being visible in AI-generated answers. This is often called GEO (Generative Engine Optimisation) or AEO (Answer Engine Optimisation).

What does Google think about AI-written copy?

In this video you can learn more about Google’s view of AI-generated content, how you can put it to use, and what you should bear in mind to create effective AI content.

How AI is affecting SEO

AI models build their answers from content that already exists on the web. They prioritise:

• credible sources
• clearly structured content
• strong brands and mentions
• content that answers questions directly

That means classic search engine optimisation is still the foundation. If you’ve got strong SEO, the likelihood of your content being used by AI goes up.

At the same time, brand and context become more important — AI doesn’t always reference with links, but it often surfaces names and players that are considered relevant and credible.

How to use AI in your SEO work

AI is also a powerful tool in day-to-day SEO. Used well, it can boost both efficiency and quality. You can use AI to:

• Analyse search intent and identify content gaps
• Generate drafts for copy, headings and structures
• Optimise content based on existing top-ranking pages
• Scale up content production
• Summarise and structure data from analyses
• Support technical SEO (e.g. spotting issues or creating rules)

Bear in mind that AI-generated content still needs to be accurate and relevant, to demonstrate expertise and credibility, and to be aligned with search intent. AI is a tool — what determines the outcome is how you use it.

How to strengthen your visibility in AI search

To appear in AI-generated answers, you need to make sure the information about your brand, your products and your category is accurate, consistent and easy to understand — both on your own website and in the external sources that AI systems may use.

Focus in particular on updating and improving content that describes your offering, on influencing the relevant external sources where your brand is mentioned, and on building a presence in the channels that AI models frequently draw information from. The goal is for AI systems to understand who you are, what you offer, and in which contexts you’re relevant.

Local SEO

Local search engine optimisation is about appearing when users are searching for products or services in a specific geographic area. It’s especially important for businesses with a physical presence or local markets — shops, restaurants or service-based businesses, for example.

To succeed with local SEO, you need to:

• optimise your Google Business Profile
• use local keywords (e.g. “dentist Stockholm”)
• have correct contact details (NAP) across the web
• gather customer reviews
• create locally relevant content

Local search engine optimisation makes you visible when the user is close to a buying decision — which often translates into a high conversion rate.

Analysis and measurement of SEO

To succeed with search engine optimisation, it’s not enough to deliver a project and hope for the best — you also need to measure, understand and continuously improve. Analysis is what tells you whether your work is actually producing results in the form of organic traffic, visibility and business value.

SEO should be tracked across three main areas:

• Visibility: How you rank for important keywords in Google and AI search.
• Traffic: How many visitors you receive from organic search.
• Conversion: What users actually do once they’re on your website.

What you should measure

A few central KPIs in search engine optimisation are:

• ranking positions
• organic traffic
• click-through rate (CTR)
• conversion rate
• revenue or leads from SEO

It’s only when you connect search engine optimisation to business objectives that you can really judge whether the work is succeeding.

Tools for SEO analysis

Common SEO tools include:

• Google Search Console – shows organic visibility, clicks and technical issues
• Google Analytics – analyses traffic and behaviour
• SEO tools (e.g. Ahrefs, Semrush) – for keywords, links and competitor analysis

Working in a data-driven way

Search engine optimisation is an iterative process. That means you continuously analyse results, identify areas for improvement, adjust content, structure or technical SEO, and then follow up again. Small improvements over time tend to add up to big results.

What doesn’t get measured can’t be improved. By working with analysis and follow-up in a structured way, you make sure your search engine optimisation keeps moving in the right direction and keeps creating value over time.

How long does SEO take?

Search engine optimisation isn’t a quick fix — but it isn’t an endless project either. How long SEO takes depends mainly on how competitive your industry is, your current position, how much needs improving, and what resources and pace you have to work with.

In many cases, you’ll start to see early results within 4–6 weeks of implementation, with greater impact often taking several months. Strong brands and established sites can see results sooner, whilst newer or weaker domains need more time to build authority.

How much does SEO cost?

The cost of search engine optimisation varies depending on the scope and quality of the work, and the working model used. So what really matters isn’t just the price, but what actually gets delivered and the business value the work creates. Read more about what SEO costs.

Project-based SEO means the work is built around a clearly defined problem, set of goals and delivery plan. The work usually starts with an SEO analysis that identifies which initiatives will have the biggest impact, followed by a concrete plan for structure, content and technical work. The direct cost can be higher, but the work is clearly tied to specific deliverables and priorities — which often produces better results over time.

Retainer SEO means paying a fixed monthly fee for ongoing work. It can work well when there’s a clear plan and a continuous need to develop content, build links and make improvements. Without clear goals, priorities and follow-up, though, there’s a risk that delivery becomes vague and the results don’t materialise.

If you don’t yet know exactly what needs doing, it’s often wise to start with a project-based setup. That way you get a clear analysis, an SEO strategy and a set of priorities. Get in touch with one of our SEO consultants to take the next step.
