How long does it take to show up in ChatGPT and Perplexity after optimizing?
TL;DR: Expect Perplexity to reflect changes in 2-7 days, ChatGPT in 7-21 days, and Gemini and Claude in 14-45 days. Listing corrections propagate on the fast end; earning new citations (roundup mentions, reviews at volume) drives the slower, durable gains. Plan a 90-day program, measure biweekly.
The short answer, backed up
Timelines differ because each engine refreshes differently: Perplexity retrieves the live web per query, ChatGPT blends search retrieval with periodically updated data layers, Gemini follows Google's local index, and Claude's web search reads what's crawlable now. Your work lands on each clock separately.
Evidence:
- Observed refresh windows across 2025-2026 GEO practice (and BookRails scan telemetry): Perplexity 2-7 days, ChatGPT 7-21, Gemini/Claude 14-45.
- Perplexity's per-query live retrieval (~780M queries/month, May 2025) makes it the fastest feedback loop for shipped fixes.
- Foursquare/Mapbox place-data updates behind ChatGPT local cards (GMBapi, 2025) propagate on data-partner schedules, typically days to weeks.
- Review platforms surface new reviews immediately, but engines' trust weighting builds over sustained velocity — a 90-day effect, not a 9-day one.
What lands when
| Change shipped | Perplexity | ChatGPT | Gemini/Claude |
|---|---|---|---|
| Robots.txt opened to AI crawlers | 2-7 days | 7-21 days | 14-45 days |
| Listing/NAP corrections | Days | 1-3 weeks | 2-6 weeks |
| New answer pages | 2-7 days (if indexed) | 1-3 weeks | 2-6 weeks |
| New roundup/citation mentions | Days after publish | 1-3 weeks | 2-6 weeks |
| Review velocity gains | 1-2 weeks | 3-6 weeks | 4-8 weeks |
Step-by-step
- Ship the fast levers first (crawler access, listings, answer pages) in week 1.
- Baseline scan the day you ship, then re-scan biweekly.
- Watch Perplexity as your leading indicator — if it hasn't moved in 2 weeks, the fix didn't land; debug there first.
- Layer slow levers (citations, review velocity) in weeks 2-6.
- Judge the program at 90 days on mention-share trend, not any single scan.
FAQ
Why did Perplexity pick me up but ChatGPT still ignores me?
Different source stacks — ChatGPT leans more on place-data partners and its own retrieval; keep listings and Bing-indexed pages tight and give it its full 21-day window.
Can anything show results in 24 hours?
Occasionally on Perplexity for a newly indexed, highly relevant page. Treat it as a bonus, not a plan.
Do answers regress?
Yes — competitors ship fixes too, and engines re-weigh sources. Alerts on mention-share drops beat quarterly surprises.
Is there a way to speed up ChatGPT specifically?
Ensure Bing indexes your key pages, keep Foursquare current, and earn one fresh third-party mention — the three inputs its local answers reward fastest.
