A generative engine optimisation agency in Colchester.
Kilij Digital is a web design and SEO agency in Colchester, Essex. Our GEO work makes your pages readable and quotable for AI search: crawler access, clear entity markup, answer-first content, and a record of which sites Google AI Overviews cite for your questions.
What GEO is.
Generative engine optimisation, also called AI SEO or LLM SEO, is the work of getting your business found and cited in AI-written answers such as Google AI Overviews, ChatGPT and Perplexity. It sits on top of ordinary technical SEO and depends on it.
Google AI Overviews cite a different set of sites from the organic results, so we measure the citation set directly. We run each search in a real browser, read the sources out of the overview, and record whether the question gets an overview with sources, one without, or none at all. Each of those calls for different work.
In our October 2026 search data for UK agency services, most national and industry searches showed an AI Overview and most town searches did not. National pages need a structure AI answers can quote. Town pages compete in the classic results.
What GEO work includes.
- AI crawler access
- A 200 response for Googlebot, GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot, a robots.txt that admits them, and a check of CDN bot settings, which on Cloudflare apply to the whole domain.
- Content in the HTML
- Pages rendered on the server, so every crawler receives the full text. A page assembled in the browser by JavaScript can reach a crawler as an empty shell.
- Entity markup
- Organization schema with sameAs, logo, legal name, @id and areaServed, pointing at your canonical domain, so engines can tell your business apart from a similar name.
- Answer-first pages
- Question-shaped headings, short self-contained answers and FAQPage schema where the questions are genuine, on the pages you want quoted.
- Content on a schedule
- Articles researched, written and published through our blog platform, which runs six client blogs, with a review step set for each client.
- Citation measurement
- A record of which sites Google AI Overviews cite for your key questions, captured in a rendered browser and re-run over time, because each capture is a snapshot.
Where this comes from.
In May 2026 our own site, then built on Lovable, sent the same 4,315-byte empty page to Googlebot, GPTBot and PerplexityBot. We rebuilt it in code on WordPress. On europemakine.com, robots.txt admits GPTBot, ClaudeBot and Google-Extended, the Organization schema links the company's verified Facebook profile, and the site serves an llms.txt file. For Önder Hukuk, an Istanbul law firm, we captured the AI Overview citations for thirteen Turkish legal questions to name the competitors Google actually cites.
Questions, answered.
What is generative engine optimisation? +
Generative engine optimisation (GEO) is the practice of making a website easy for AI search tools to read, trust and cite. It covers crawler access, server-rendered content, entity schema such as Organization with sameAs, answer-first writing and FAQ markup, plus measuring which sites AI answers cite.
How is GEO different from SEO? +
GEO builds on SEO. AI answers draw on pages that search engines can crawl and index, so technical SEO comes first, and GEO adds the entity markup, answer-first structure and citation tracking that help an AI answer name your business.
What does an AI SEO agency do? +
An AI SEO agency, also called an LLM SEO or GEO agency, works on visibility in AI-written answers as well as in search results. At Kilij that means checking AI crawler access, completing entity schema, restructuring key pages around the questions buyers ask, publishing content on a schedule and measuring AI Overview citations.
Can you measure whether Google AI Overviews cite us? +
Yes. We run each search in a real browser and read the cited sources from the AI Overview. Captures vary by person and by day, so each one is recorded as a snapshot and re-run, and AI Overview visits show up in analytics as ordinary google.com referrals, so this capture is the way to see the citation set.
Do AI crawlers need access to my site? +
Yes, an AI tool can only quote pages its crawler can read. We check that GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot get a 200 response, that robots.txt admits them, and that no CDN setting blocks them across the domain.
