SEO in 2027 still rests on three foundations: a site that search engines can crawl and understand, content that answers real questions better than the alternatives, and a reputation that other sites confirm with links and mentions. What has changed is where answers appear. Results pages now mix ordinary links with AI-written summaries, and assistants answer questions by reading the web, so a business website has to be useful to people and legible to machines at once. This is our SEO guide 2027: how search works now, what a solid technical base looks like, how to plan content and links, how to be cited in AI answers, and how to measure progress without chasing the wrong numbers.

How does search work now?
Search engines still do three things: they crawl pages, index what they find and rank results for each query. Google describes that process openly in its documentation on how Search works, and it remains the best starting point for anyone new to the subject.
What has shifted is the results page. For many informational queries an AI summary now appears above or among the ordinary results, drawn from pages the engine trusts. Chat assistants answer questions the same way. For a business this means two things:
- Pages must be clear enough to quote. A direct answer near the top, well-structured headings, accurate facts.
- Trust carries more weight. Content that shows real experience, a named company behind it and consistent information across the web is more likely to be cited.
Search engine optimisation is therefore less about tricks and more about being the most useful, best-organised source on a subject you genuinely know. That is also why the budget for SEO has moved. In our experience AI now carries the repetitive part of the work: crawling a site for errors, preparing images, drafting outlines and first versions, testing pages on every screen, first-pass translations. What the budget buys is the part that decides the result: the strategy, the editorial judgement, the writing that sounds like your company and the final review of every fact.
SEO guide 2027: what is the technical base?
Technical SEO is what lets everything else work. If pages cannot be crawled, indexed or loaded quickly, the best content on the subject goes unseen.
What to decide first
- Site structure. A logical hierarchy where every important page is reachable in a few clicks.
- Clean addresses. Readable, stable, lower-case addresses: see our note on SEO-friendly URLs.
- Indexing rules. Which pages should appear in search, which should not, and a sitemap that lists the first group only.
- Speed and Core Web Vitals. Fast loading, a stable layout and a quick response to input on real phones, measured with the Core Web Vitals that Google reports.
- Mobile first. Search engines assess the mobile version of your site, so the phone layout is the one that counts.
Most of this is decided at the moment a site is built. A website developed with search in mind from the first day costs little more than one built without it; fixing the same things after launch costs a redesign. Our article on website development in 2027 lists that groundwork.
What to leave for later
Log-file analysis, rendering experiments and fine-grained crawl budget tuning matter for sites with hundreds of thousands of pages. For a business site with a few hundred pages they can wait until the fundamentals are in place. A short technical audit at the start of a project, and once a year afterwards, catches most problems before they cost visibility.
What content ranks?
Content is where a site earns its rankings. Good content in 2027 has four qualities:
- It matches intent. Someone searching “how much does a website cost” wants a range and the factors behind it, not a sales page.
- It answers early. The first paragraph states the answer; the rest supports it.
- It is specific. Real examples, clear steps, honest trade-offs.
- It is organised. One page per topic, grouped in clusters around a pillar guide, linked to each other.
Do not aim only at broad terms. The longer, more specific phrases people type when they know what they want are often where qualified enquiries come from, and they are far less contested. Our own guide to how much a website costs is written for exactly that kind of question.
Structured data tells engines what a page is: an article, a service, a vacancy, a set of questions and answers. It guarantees nothing, but it removes ambiguity and costs little.
AI speeds content work: research, outlines, first drafts and variations. At Odduel we use it for exactly that, so writers and editors spend their time on accuracy, voice and the details only someone who knows the subject can add. Content published without that review tends to be generic, and generic pages rarely earn citations. The same division of labour runs through AI in web design and development more widely.
Do links still matter?
Links from other reputable sites remain a signal of trust. On-page work is what you control on your own site; off-page work is the reputation you build elsewhere, and it cannot be bought safely.
Sustainable ways to earn links and mentions:
- Publish something genuinely useful: a guide, a tool, original research.
- Appear in the directories and associations that matter in your sector.
- Contribute expert commentary to the trade press.
- Build relationships with partners, suppliers and clients who can reference your work.
Internal links count too. Every article should link to its pillar and to the service it supports, and the pillar should link back. Paid links breach the search engines’ guidelines, and the risk outweighs any short-term gain.
How do local and international SEO differ?
If you serve customers in specific places, local SEO matters: an accurate business profile on Google, the same name, address and telephone everywhere on the web, and a page for each location you genuinely serve. A restaurant or a shop lives or dies by this. When we built the website for Nothing To Eat, a sandwich brand in Amsterdam, a section about its neighbourhood suppliers stood in the page from its first version, not as an afterthought.
For international sites, each language needs its own addresses, translated slugs, hreflang annotations linking the versions, and keywords researched in that language rather than translated word for word. A page that ranks in English will not rank in German simply because it was translated. The table below shows the difference between the two approaches:
| Question | Literal translation | Researched per language |
|---|---|---|
| Keyword | The English term, translated | The term people in that market actually type |
| Address | The English slug under /de/ | A German slug |
| Title and description | Translated | Written for that market’s search results |
| Result | Indexed, rarely ranked | Competes on equal terms |
How do you appear in AI answers?
Being cited in an AI answer follows the same principles as ranking, with a few additions:
- Write extractable answers. A clear definition or summary in two or three sentences under the relevant heading.
- Keep facts consistent. Company details, services and locations should match across your site, your profiles and the directories.
- Let crawlers in. Decide deliberately which AI crawlers your robots file allows, and write that decision down.
- Show who you are. Organisation details in structured data, real contact information, a visible track record.
No one can promise a citation in an AI answer, and you should be wary of anyone who does. What you can do is make your site the clearest source on your subject, and keep it that way.
How do you measure SEO?
Measure what connects to the business:
- Visibility in Google Search Console: impressions and clicks for the queries that matter.
- Engagement with the pages that bring visitors: do they read, click through, enquire?
- Conversions: enquiries, sign-ups and sales attributed to organic search.
- Technical health: indexing errors, Core Web Vitals, broken links.
Rankings for a single keyword move daily and say little on their own. Look at trends over months and tie them to the enquiries that arrived. A digital marketing strategy that puts search beside paid and social makes those numbers easier to read.
What does an SEO plan you can keep look like?
The most common reason SEO fails is not a lack of knowledge but a lack of rhythm. A plan that is realistic for your resources will outperform an ambitious one that stops after two months.
A workable annual structure for a business site:
- First quarter: audit and fix the technical base, set up measurement, agree the main topics and clusters.
- Second quarter: publish or rewrite the pillar page of each cluster, and improve the service pages that bring enquiries.
- Third quarter: add supporting articles, earn links through partners and press, refresh pages that are losing visibility.
- Fourth quarter: review results, prune or merge weak pages, plan the next year.
Two habits make the biggest difference. First, update before you create: an existing page with some visibility usually responds faster to improvement than a new page does to publication. Second, link deliberately, as described above.
AI helps keep the rhythm. At Odduel we use it to watch rankings and crawl errors, draft briefs for writers and suggest internal links across a growing library of pages. People decide what to publish, check every fact and make sure each page sounds like the company. That is how a small company keeps a large site in good health without a large budget, and it is the way we work from Barcelona and São Paulo.
Questions people ask
How much should a business budget for SEO?
Budget for a technical base built into the site from the start, then a steady monthly amount for content and monitoring. In our experience a one-off fix without ongoing content rarely holds its position for long. A local service needs far less than a national e-commerce site.
How long does SEO take to show results?
Technical fixes can show an effect within weeks, once the pages have been crawled again. Content and reputation build over months, and a new site usually needs six months or more before its visibility is meaningful. Anyone promising first-page rankings in days is describing paid advertising or something riskier.
Is SEO still worth it with AI answers?
Yes. AI answers are built from pages that rank and that engines trust, so the work that earns a ranking also earns a citation. The sites that lose are the ones with thin, generic pages, which AI answers skip over entirely.
What should I ask an SEO partner?
How they decide which queries to target, what they will change on your site, how they earn links, how they report, and what they refuse to do. Ask for examples of their work and the reasoning behind each one.
Does AI make SEO cheaper?
It makes the repetitive part cheaper: audits, drafting, image preparation, testing and first translations go many times faster. It does not replace subject knowledge or editorial judgement, and search engines are good at spotting content that has neither. The saving is real; it should go into better content, not into more of the same.
Start with the technical base, then build content in clusters around what your clients actually ask. If you want help planning or running that work, our digital marketing service covers the SEO described here, from the audit to the monthly rhythm, or talk to us about your project.
