How long does AI visibility take?
Answer
Timing depends on the step. OpenAI's crawler page, checked Oct. 29, 2026, says a robots.txt change can take about 24 hours to reach ChatGPT search, and Perplexity's page says up to 24 hours. Google's recrawl guide, updated Dec. 10, 2025, says crawling "can take anywhere from a few days to a few weeks."
The published timings
- ChatGPT: OpenAI says it can take about 24 hours from a robots.txt update for its systems to adjust.
- Perplexity: its page says it may take up to 24 hours for its systems to reflect changes.
- Google: Google's recrawl page says crawling can take a few days to a few weeks.
- Seer Interactive, Aug. 27, 2026, gives fix times by cause. Misreads of your own site are fast, stale live retrieval sources take days to weeks, and training data takes months.
What these timings leave out
These numbers cover access and correction. None of the sources states how long it takes for a new page to be cited. Promptwatch, Sept. 17, 2026, says citation relevance holds for roughly 8 to 14 weeks before a refresh helps.
Because answers change between runs, SparkToro, Jan. 28, 2026, says you need to ask over and over again to see an AI's set of recommendations. Measure over repeated runs.
How to track progress
- Record today's baseline across a fixed question set before you change anything.
- Fix access first and log the date of each change.
- Rerun the same questions weekly across each engine, several times each.
- Compare buckets over time, not single answers.
Record a baseline of where ChatGPT and Google AI name you today, then compare after each change.
