Generative engine optimization (GEO) is the practice of making a brand’s content easy for AI answer engines such as ChatGPT, Perplexity, Gemini and Google’s AI Overviews to find, understand and cite. A good implementation starts with a small pilot on a few topics, measures citation share, then extends what worked across the site.
The checklist below follows that order. It is written for teams that already run normal SEO and want to add GEO without rebuilding everything.
What should the pilot cover?
Choose one product line or service and 20 to 40 questions buyers ask about it. A narrow pilot makes cause and effect visible. If you change fifty pages at once, you will not know which change mattered.
- Pick one topic cluster with business value and existing pages.
- Write the question list using sales calls, support tickets and search queries.
- Run each question in ChatGPT, Perplexity, Gemini and Google, and log results.
- Record whether your brand is mentioned, cited with a link, or absent.
- Note which domains are cited instead of you.
Phase 1: technical access checklist
AI systems cannot cite what they cannot read. These checks take a day and fix the most basic blocker.
- robots.txt allows the crawlers you want: Googlebot, Bingbot, OAI-SearchBot, GPTBot (if you allow training), PerplexityBot, ClaudeBot.
- Security tools and CDNs do not challenge those user agents with captchas.
- Key content is in the HTML, not only rendered by JavaScript after load.
- Pages return 200, load in reasonable time and have a clear canonical URL.
- XML sitemap is current and submitted to Google Search Console and Bing Webmaster Tools.
Bing matters more than its search share suggests, because several AI products use Bing’s index for retrieval. Many teams have never opened Bing Webmaster Tools.
Phase 2: content checklist
Answer engines prefer passages that resolve a question on their own. That favours a particular writing style.
Page-level checks
- The first paragraph answers the main question directly in two or three sentences.
- Headings are written as the questions people ask.
- Each section can be understood without reading the rest of the page.
- Concrete facts are present: specifications, steps, prices or ranges, conditions.
- The page shows who wrote it and when it was last updated.
Site-level checks
- Comparison pages exist for the main alternatives buyers consider.
- An about page states clearly what the company does, where and for whom.
- Organization and Product schema markup are valid and consistent with page text.
- Brand name, address and service descriptions match across the site and profiles.
Does third-party presence matter for GEO?
Yes, often more than on-site work. Answers about “best X for Y” frequently cite review platforms, industry publications, Wikipedia and community discussions. If the logged results show the same five external domains cited repeatedly, those domains are your outreach list.
This is ordinary digital PR with a sharper target: getting accurate, specific mentions on the sources AI engines already trust for your topic.
How do you measure a GEO pilot?
There is no Search Console for AI answers. Measurement relies on repeated prompt checks and analytics. Run the same question set every two to four weeks, in a clean session, and record the same fields each time.
- Mention rate: share of questions where the brand is named.
- Citation rate: share where a link to your site is shown.
- Accuracy: whether the description of your brand is correct.
- Referral traffic from chatgpt.com, perplexity.ai and similar sources in analytics.
- Branded search trends in Google Search Console.
Expect noise. Answers vary between runs, so look at trends across several checks rather than single results.
How Alien Road applies GEO from pilot to production
In a typical engagement, discovery produces the question set and the baseline log across four engines. Setup handles the technical access checks first, then rewrites the pilot pages in an answer-first structure and adds missing comparison content.
After two or three measurement rounds, the team reviews which changes moved mention and citation rates. Those patterns become a written content standard, which is then applied to the next topic cluster. Reporting shows each cluster’s baseline and current rates side by side, along with the external sources still cited instead of the client.
How do you move from pilot to production?
A pilot proves which changes help in your niche. Production is about applying those changes across many pages without losing quality. The step most teams skip is writing the lessons down as a standard before scaling.
- Document the page template that improved citation rates, with an example.
- Train writers and editors on the answer-first structure and question headings.
- Add GEO checks to the publishing checklist, next to normal SEO checks.
- Extend the question set to the next topic cluster and log a fresh baseline.
- Schedule measurement rounds on the calendar so they actually happen.
Prioritise clusters by business value, not by ease. A cluster with fewer questions but higher deal values is often a better second target than a large informational topic that brings readers who never buy.
Finally, keep a change log. When citation rates shift, you need to know whether it followed your own update, a competitor’s new page or a change in the engine itself. Without dates and notes, every movement in the data turns into speculation, and the programme loses credibility with the people funding it.
Common pilot mistakes
Three mistakes recur. Teams change too many pages at once and cannot see what worked. They measure once and treat a single result as a trend. And they focus only on their own site while the answers keep citing third-party reviews. Avoiding these three makes even a small pilot informative.
Write each lesson as a rule with an example page, so the next writer can apply it without attending the original meetings.
Where to start this week
Write 20 buyer questions for your most important service and run them in ChatGPT and Perplexity. Log mentions, citations and the competing domains.
At the same time, open your robots.txt and check it against the crawler list above. Fixing access and having a baseline log are the two steps every later GEO decision depends on.
