# How long does GEO take to work? > Some AI answers can change within weeks. Others won't move until the next AI model ships. Here is what sets the pace, what you can speed up, and how to tell real progress from day-to-day noise. Updated October 7, 2026 · AI Syndicate team · https://www.aisyndicate.com/blog/how-long-does-geo-take/ **Quick answer:** It depends which part of the answer you want to change. Live-search answers update once crawlers re-read your pages, which Google says takes days to weeks. Answers from a model's memory change only when a new model ships. Reviews, lists and press take as long as earning them. **Our advice:** judge progress at 60 to 90 days. **Our take:** Before asking whether GEO worked, ask which clock that fix runs on. Unblocking a crawler can register within a day, retraining a model happens on the AI company's calendar, and reviews arrive when customers write them. Judging all three against one deadline makes fast wins look like flukes and slow work look like failure. Sort each change by its clock, then hold each to a fair date. ## What are the key facts about how long GEO takes? These are the timing facts the AI and search companies publish themselves. Each was read on 7 October 2026. | Fact | Detail | Source | | --- | --- | --- | | Google recrawls on its own schedule | "Crawling can take anywhere from a few days to a few weeks" | Google | | Some pages take longer | For AI features, Google says crawling "can take anywhere from several days to several months" | Google | | A single indexing request | Indexing "typically takes only a day or so, but can take much longer in some cases" | Google | | Asking twice doesn't help | Requesting a recrawl many times for one URL "won't get it crawled any faster" | Google | | ChatGPT search and robots.txt | It "can take ~24 hours" after a robots.txt change for OpenAI's search systems to adjust | OpenAI | | Perplexity and robots.txt | It "may take up to 24 hours" for Perplexity's systems to reflect robots.txt changes | Perplexity | | IndexNow helps, with no promise | "Submitting a URL does not guarantee immediate indexing" | IndexNow | | Model memory has an end date | OpenAI lists knowledge cutoffs of Apr 30, 2026 and May 18, 2026 for its current flagship models; Anthropic lists Jun 2026 for its newest Claude models | OpenAI, Anthropic | > **What this means in plain words:** the fastest part of GEO moves in days. The slowest part waits for the next AI model, which you can't hurry. ## Why is there no single answer to how long GEO takes? Because an AI answer is built from three different places, and each one updates at its own speed. **GEO** (Generative Engine Optimization) is the work of getting AI tools like ChatGPT, Gemini, Perplexity, Copilot, Claude and Google's AI answers to name your business. 1. **Live search.** Many engines search the web while they write. They can only use pages their crawlers (the robots that read websites) have read and stored. This part moves in days to weeks. 2. **Model memory.** Every AI model also learned from a huge pile of text up to a fixed date. What it "knows" from that only changes when the company trains and releases a new model. This part moves in months, and you don't control it. 3. **Off-site signals.** Reviews, "best of" lists, news stories, Reddit threads and directory listings. AI engines read them too. They take as long as it takes to earn them. So "how long does GEO take?" really means "which of these am I trying to change?" Our page on [where AI engines get their sources](/blog/where-ai-engines-get-their-sources/) explains the split in more detail. ## How fast can live-search AI answers change? As fast as the engine's crawler re-reads your page and adds the new version to its index (its stored copy of the web). That is usually days to weeks, not hours. Google says "Crawling can take anywhere from a few days to a few weeks." [Google](https://developers.google.com/search/docs/crawling-indexing/ask-google-to-recrawl) Its page on AI features is more cautious, saying crawling can take "several days to several months, depending on how often our systems determine a page needs to be refreshed." [Google](https://developers.google.com/search/docs/appearance/ai-features) Google's AI Overviews and AI Mode have no special shortcut. To appear as a supporting link, a page "must be indexed and eligible to be shown in Google Search with a snippet." [Google](https://developers.google.com/search/docs/appearance/ai-features) So Google's AI answers move at the speed of normal Google indexing. Other engines rely on other indexes. Microsoft says Copilot "may fetch information from the Bing search service." [Microsoft](https://learn.microsoft.com/en-us/microsoft-365/copilot/manage-public-web-access) For ChatGPT, OpenAI says its OAI-SearchBot crawler "is used to surface websites in search results in ChatGPT's search features." [OpenAI](https://developers.openai.com/api/docs/bots) Perplexity says PerplexityBot "is designed to surface and link websites in search results on Perplexity." [Perplexity](https://docs.perplexity.ai/guides/bots) Anthropic runs Claude-SearchBot, which it says works "to improve search result quality for users." [Anthropic](https://support.claude.com/en/articles/8896518-does-anthropic-crawl-data-from-the-web-and-how-can-site-owners-block-the-crawler) > **One fast fix:** if your robots.txt file was blocking these crawlers, unblocking them is picked up quickly. OpenAI says about 24 hours; Perplexity says up to 24 hours. [OpenAI](https://developers.openai.com/api/docs/bots) [Perplexity](https://docs.perplexity.ai/guides/bots) The pages still need to be read after that. ## How can you help crawlers find your changes sooner? Tell them, and don't make them guess. You can't force a crawl, but you can remove delays. - **Keep a sitemap.** A sitemap is a file that lists your pages. Google says it helps engines discover URLs but "doesn't guarantee that all the items in your sitemap will be crawled and indexed." [Google](https://developers.google.com/search/docs/crawling-indexing/sitemaps/overview) - **Request indexing in Google Search Console** for a page you just changed. Use the URL Inspection tool. Google says indexing "can take up to a week or two," and there is "a daily limit" on requests. [Google](https://support.google.com/webmasters/answer/9012289) Asking again for the same page won't make it faster. [Google](https://developers.google.com/search/docs/crawling-indexing/ask-google-to-recrawl) - **Use IndexNow for Bing-fed engines.** IndexNow is a free way to ping search engines the moment a page changes. A submission to one participating engine "will be shared across all IndexNow-enabled search engines," including Bing. [IndexNow](https://www.indexnow.org/faq) [Bing](https://www.bing.com/indexnow) That matters for Copilot, which draws on Bing. More in our guide to [Bing and AI answers](/blog/bing-and-ai-answers/). - **Let the AI crawlers in.** If robots.txt blocks OAI-SearchBot, Claude-SearchBot or PerplexityBot, nothing else on this list helps those engines. Our [AI crawler guide](/blog/ai-crawlers-robots-txt/) shows which to allow. None of these is a guarantee. IndexNow's own FAQ says "Submitting a URL does not guarantee immediate indexing." [IndexNow](https://www.indexnow.org/faq) They just stop you from waiting longer than you have to. ## When do answers from an AI model's memory change? Only when a new model is trained and released. Nothing you publish today reaches the memory of a model that has already been built. Every model has a cutoff date: the point where its learning stopped. On 7 October 2026, OpenAI's models page listed knowledge cutoffs of Apr 30, 2026 and May 18, 2026 for its current flagship models. [OpenAI](https://developers.openai.com/api/docs/models) Anthropic listed a reliable knowledge cutoff of Jun 2026 for its newest Claude models. [Anthropic](https://platform.claude.com/docs/en/about-claude/models/overview) Put simply, even the newest models were finished learning months before today. A page you publish this week can't be in any of them. It can only be found through live search, or picked up when a later model is trained. This is why answers given *without* a web search are slow to change. In the short term, the reliable fix is to be easy to find in live search. Memory catches up later, on the AI company's timetable. > **Our advice:** don't pay anyone who promises to change what a model "remembers" by a set date. No outsider controls when models are retrained. ## How long do reviews, lists and press take to count? As long as it takes to earn them, plus the time for engines to read the pages they appear on. There is no shortcut for either half. Reviews arrive when customers write them. A place on a "best of" list comes when an editor updates it. None of this runs on your schedule. Then the same crawl delay applies: a mention on a page that hasn't been re-read yet is invisible to live search. That is why off-site work is the slow, steady part of GEO. It is also often the part that decides who gets recommended. Our guides on [reviews](/blog/do-reviews-affect-ai-recommendations/), [best-of lists](/blog/do-best-of-lists-help-ai-recommendations/) and [Reddit](/blog/reddit-and-ai-answers/) cover each one. ## What should you expect week by week and month by month? Quick technical fixes can show within weeks; the full picture takes months. The table below is **our advice**, not a promise. It comes from how the three clocks above work, not from an average of client results. | When | What can realistically change | What usually hasn't yet | | --- | --- | --- | | Week 1 | Crawler blocks removed; sitemap and indexing requests sent; baseline of questions recorded | AI answers. Don't judge anything yet | | Weeks 2 to 4 | Changed pages re-read and re-indexed by some engines; live-search answers may start citing them | Model memory; most off-site work | | Months 2 to 3 | Enough repeated checks to see a trend on live-search engines; first new reviews and listings being read | Slow-to-crawl pages; anything that depends on a new model | | Months 3 to 6 | Off-site signals starting to add up; a fair read of whether the work is paying off | Memory-only answers on older models | | 6 months and beyond | Newer models may reflect what is now on the web about you | Nothing is ever "done": rivals keep working too | > **Our advice:** set your first real review at 60 to 90 days, against the same questions you started with. Earlier than that, you are mostly watching noise. One published result, labelled as the client's own: [Complete Home Painting](/case-studies/complete-home-painting/), a painting contractor in Alabama, reports that it "saw our first lead from ChatGPT within 30 [days]" of starting with us. That is client-reported, one business, and not a promise. Every result we publish, with its label, is on our [results page](/results/). ## Why do results jump around in the first few weeks? Because AI answers change from one run to the next even when nothing about your business has changed. Early ups and downs are mostly that noise, not progress or failure. Models choose words with some built-in chance, the web they search shifts daily, and answers differ by location and account. We explain all five causes in [why AI answers change](/blog/why-ai-answers-change/). So a screenshot from day three where you appear means little, and so does one from day ten where you don't. What matters is the share of answers that name you, over many runs, and whether that share climbs. ## How do you tell whether GEO is working? Ask the same questions, on the same engines, again and again, and track how often you're named. Change only one thing at a time: your site, not your test. 1. **Pick the questions first.** Write down 10 to 30 questions your buyers really ask. Our guide on [how to choose prompts to track](/blog/how-to-choose-prompts-to-track/) helps. 2. **Record a baseline before any work starts.** Without one, you can't tell what changed. 3. **Check several engines.** ChatGPT, Gemini, Perplexity, Copilot, Claude and Google's AI answers each move at their own speed. A win on one and silence on another is normal early on. 4. **Repeat on a schedule**, weekly or monthly, and compare shares, not single answers. 5. **Note what you changed and when**, so a rise can be matched to the work behind it. Our page on [how to measure AI visibility](/blog/how-to-measure-ai-visibility/) covers the numbers to watch. To put a value on the result, see [how to calculate GEO ROI](/blog/how-to-calculate-geo-roi/). ## FAQ ### How long does GEO take to work? It depends which part you change. Live-search answers can update once crawlers re-read your pages, which Google says takes "a few days to a few weeks." [Google](https://developers.google.com/search/docs/crawling-indexing/ask-google-to-recrawl) Answers from a model's memory only change with a new model. Off-site signals take as long as earning them. Our advice: judge it at 60 to 90 days. ### Can I make ChatGPT update what it says about my business faster? You can make sure ChatGPT search can read you. OpenAI says OAI-SearchBot surfaces sites in ChatGPT search, and robots.txt changes take about 24 hours to register. [OpenAI](https://developers.openai.com/api/docs/bots) You can't change what an existing model learned in training; that only updates with a new model. ### Does requesting indexing in Google Search Console speed things up? It can help one page get looked at. Google says indexing "typically takes only a day or so, but can take much longer," there is a daily limit, and a request doesn't guarantee the page appears. [Google](https://support.google.com/webmasters/answer/9012289) Asking again for the same page won't make it faster. [Google](https://developers.google.com/search/docs/crawling-indexing/ask-google-to-recrawl) ### Why did I show up in an AI answer one day and not the next? Because AI answers vary from run to run, by location and as the web changes. One answer proves little either way. Track how often you're named across many runs and engines. See [why AI answers change](/blog/why-ai-answers-change/). ### Should I stop GEO if nothing changes after a month? Our advice: not on one month alone. Check that crawlers can reach your pages and that the pages are indexed. Then review at 60 to 90 days against the same questions. If nothing has moved by then, ask what was actually changed. ## Sources 1.
