This glossary explains the GEO and AI search terms small business owners keep hearing, in plain language and in the order you are likely to need them. AI tools such as Google AI Overviews, Gemini, Perplexity and ChatGPT now handle millions of searches before anyone clicks a link.
That shift brought a pile of new jargon in July 2026, when a whole category of GEO software appeared and Google published fresh guidance. Each entry below gives a short definition and the reason it matters to your business.
The core terms
- SEO: the work of earning visibility in classic search results, the familiar list of blue links. It remains the foundation for everything else in this glossary.
- GEO (Generative Engine Optimization): shaping your content so AI systems can cite it inside the answers they generate. The goal moves from winning a blue link to being included in AI answers across Claude, Perplexity, Gemini, Google AI features and ChatGPT.
- AEO: a related term that Google files next to GEO as part of SEO, not as a discipline of its own.
- The Google view: Google's new guide treats AEO and GEO as parts of SEO for Google Search. In practice you do not need a second strategy, only a sharper version of the one you already have.
Where AI answers appear
- AI Overviews: AI-generated answers that Google shows inside its search results. Industry reports in 2026 say somewhere between 47 and 64 percent of desktop and mobile queries now show one, compared with about 25 to 30 percent when they first rolled out widely in 2024.
- AI Mode: another Google AI search experience, covered by the same new guide alongside AI Overviews.
- AI answer tools: services such as ChatGPT, Perplexity, Gemini and Claude that reply to questions directly instead of handing back a list of links.
Citation terms
- Citation: a link or mention that credits your page as a source inside an AI answer. Earning one is now the main goal, since a customer may meet your brand inside an AI reply before visiting your site.
- Citation rate: how often a platform includes sources at all. Perplexity includes sources in 97 percent of its answers, against just 16 percent for ChatGPT.
- Citation overlap: how closely the sources AI tools cite match the top Google links. Research from GEO firm Brandlight suggests that overlap has dropped below 20 percent, down from 70 percent, so a number one ranking no longer places you in front of the AI answer by default.
- Source pool: where a platform draws its citations from. A CiteLens benchmark traced about 90 percent of Google AI Mode and Perplexity citations back to the Google top 10, against only 30 percent for ChatGPT.
- GEO platforms: a new category of software that measures whether AI tools mention or recommend your brand. A wave of these tools appeared in July 2026, because classic SEO tools cannot answer that question.
What Google says your pages need
- Non-commodity content: writing that offers unique insight past common knowledge rather than generic tips anyone could produce. Google gives it particular weight, according to Search Engine Journal coverage of the new guide.
- Snippet eligibility: a page must be indexed and eligible for snippets before it can appear in the generative AI features of Google.
- Semantic HTML and JavaScript SEO: two technical practices on the list Google recommends, along with crawling best practices. The guide asks for semantic HTML where possible.
- Page experience and duplicate content: the same guidance asks for a good page experience and fewer duplicate pages.
- llms.txt, content chunking and AI-specific rewriting: tactics often sold as AI shortcuts. Google says that none of them, and no special schema, is needed for its generative AI features.
Technical access terms
- AI crawler or AI bot: the automated visitor an AI platform sends to read your pages. Many sites block these bots without knowing it, which keeps their content out of AI answers.
- User agent: the name a bot reports when it visits, such as GPTBot or ClaudeBot. Your server logs show which of these names have reached your site.
- robots.txt: a file on your site that bots read for crawl rules. Review it alongside your server logs whenever you check AI access.
- Cloudflare default setting: a recent change made blocking AI bots the default, which may have cut off AI access to your site without any warning.
Content quality terms
- Recency bias: AI systems strongly favor current content. Refresh key pages every three months or sooner, since older pages can slip down the citation list even after ranking well in the past.
- Proof: statistics, quotations and outside sources inside your content. Peer-reviewed Princeton research found that statistics raised AI visibility by 41 percent, quotations by 28 percent and external citations by 115 percent for lower-ranked content.
- Quotable answer: a plain-language answer placed at the top of a page before the detail. Pages that earn citations tend to be current, clear, well-structured and consistent between your website and your profiles elsewhere.
- Brand consistency: describing your business the same way in your Google Business Profile, your social bios and your website, so AI systems can confirm who you are.
Measurement terms
- Click-through rate: the share of people who click a result after seeing it. Seer Interactive tracked 2.43 billion impressions over time and saw organic click-through rates drop significantly on queries with AI Overviews before partly rebounding.
- AIO-present and AIO-absent queries: searches with and without an AI Overview. The click gap between the two is the new normal that businesses need to plan for.
- Branded search volume: how many people search for your business by name. Brands cited in AI Overviews report gains here, along with higher trust perception and stronger conversion rates, because their visitors arrive with more context and intent.
Local terms
- NAP: your business name, address and phone number. AI tools look for consistent NAP details when deciding which local business to suggest.
- Google Business Profile and Merchant Center feeds: the tools Google recommends for local business and product visibility in AI responses.
- Trust before the click: the idea that reviews, case evidence, expert profiles, brand mentions and strong branded pages carry more weight than before, because people often meet your name inside an AI answer first.
A Michigan resident who asks an AI tool which accountant, plumber or web designer to hire gets an answer built from review platforms, structured data, authoritative local content and consistent NAP details. Each of those inputs is something a local business can improve.
Putting the terms to work
The July 2026 takeaway is that GEO now belongs in any serious visibility plan. The winners will be the businesses that people and machines find clearest, most consistent and easiest to trust, not the loudest ones.

Frequently Asked Questions
In plain terms, how does GEO differ from SEO?
Google treats GEO and AEO as parts of SEO rather than separate fields. What changes is the target: instead of only ranking a page, you aim to be a cited source inside AI answers on Google, ChatGPT, Perplexity and Gemini, and solid SEO basics still feed that work.
Which glossary terms can I safely skip, such as llms.txt and AI schema?
You can skip llms.txt files, AI-specific rewrites and special schema markup, because Google's published guidance lists them as unnecessary for its generative AI features. Pages only have to be indexed and qualify for standard snippets, with clear, people-first content.
What do user agent and server logs mean for checking AI bot access?
A user agent is the name a bot reports, such as GPTBot or ClaudeBot, and your server logs record those visits. Review the logs and your robots.txt file, and if your site runs on Cloudflare, confirm its newer default setting is not blocking AI crawlers.
