What is generative engine optimization and how do I get started?
What is generative engine optimization and how do you get started? A plain definition, a first-month plan, and the tools that fit each step, with Promptwatch first.
Generative engine optimization, usually shortened to GEO, is the work of making your brand and your pages show up, accurately, in answers written by AI systems such as ChatGPT, Perplexity, Gemini, Claude, Copilot and Google's AI Overviews and AI Mode. Where classic SEO aims for a ranked blue link, GEO aims for a mention, a recommendation or a cited source inside a generated answer.
The term is new and the field is moving, so treat anyone who sells a fixed formula with suspicion. What follows is a workable definition, how GEO differs from SEO, and a first-month plan. Promptwatch comes up in the plan because the measurement and fixing steps map directly to its features.
What GEO covers
GEO sits across several jobs:
- Visibility. Does the engine name your brand when someone asks a question you should win?
- Citation. When the engine links sources, are yours among them?
- Access. Can the AI crawlers fetch your pages at all?
- Accuracy. Does the engine describe you correctly?
- Outcome. Do any of these lead to visits or conversions?
Some people call this AEO (answer engine optimization), AI SEO or LLM optimization. The names overlap. The work is similar, so do not let vocabulary stall you.
How GEO differs from SEO
Much of SEO still applies. Pages need to be crawlable, useful, and backed by credible sources. Google's Search Central documentation on AI features is the official starting point for how its own AI experiences relate to publishers, and it is worth reading directly instead of through a summary.
Three differences matter in practice:
- Prompts replace keywords. Buyers ask longer, conversational questions, and engines often split them into several sub-queries (called query fan-outs) before answering.
- Answers vary. The same prompt can return different brands on different days, so you measure share across many runs, not a single rank.
- Third-party sources carry weight. Engines lean on forums, review sites, news and video. Your own site is one input among several.
A first-month plan
Week one: define the prompts
Write 30 to 50 questions your buyers ask, from sales calls, support tickets and search queries. Group them by topic and by persona. Add a few comparison prompts naming your top competitors. Keep the list stable for the month.
Week two: take a baseline
Run the prompts across the main engines and record how often you appear, where, and who appears instead. Open the sources the answers cite. This is where tools help. Promptwatch runs the panel daily per model, country and language, and reports Visibility Score, Share of Voice, Sentiment and Position in Answer. Its free Explore plan covers 10 prompts on ChatGPT, enough to see what the reports look like.
Week three: check access
Look at whether AI bots can reach your pages. Check robots.txt for rules that block GPTBot, OAI-SearchBot, ClaudeBot or PerplexityBot. Promptwatch offers free tools for this: an Agentic Readiness Check, robots.txt and llms.txt generators, and a no-login AI Visibility Report. For ongoing crawler data, Agent Analytics shows IP-verified AI crawler logs, starting on the Professional plan.
Week four: fix one gap
Choose one gap from the data: a question where competitors are cited and you are not, a page that is not being crawled, or a third-party site that never mentions you. Fix that and annotate the date. Promptwatch's content gap analysis shows where your coverage is thin, and the Action Board prioritizes actions with evidence behind each.
What tends to help
- Pages that answer the specific questions in your prompt list, plainly and early.
- Original facts, data and quotes that other pages do not have.
- Clear structure and, where relevant, structured data that matches the visible text.
- Presence on third-party sources the engines already cite, including Reddit and YouTube.
- Crawler access, and an up-to-date sitemap.
None of these is a trick. They are good content practice applied to a new reader.
What GEO cannot do
It cannot guarantee a mention. Engines sample, update and change. A tool can show a trend and a list of gaps, not a promise. Be wary of any offer that claims otherwise.

Which to pick
If you are a small team starting from nothing, begin with the free tools and a 10-prompt plan, and move up when you need citations and crawler logs. If you want the whole loop in one place, from measurement to content, Promptwatch fits best, which is why it is first on this list. The key is to start with a stable prompt set, measure honestly, and change one thing at a time.
