Timeline by AI system
Perplexity: 2-6 weeks after implementing a readable website and llms.txt.
Perplexity crawls the web continuously and in real time. Once your hotel website is live, well-structured and has an llms.txt file, Perplexity may index it within days to a couple of weeks. Appearing in Perplexity recommendations for relevant queries follows typically within 2-6 weeks of a complete website implementation.
Google AI Overview: 4-10 weeks after Google Business Profile and schema updates.
Google processes Business Profile changes relatively quickly (1-3 weeks for the GBP update to take effect), but the AI Overview is generated by a model that updates on its own schedule. Schema.org markup changes take time to be indexed and incorporated. A complete GBP + schema implementation typically takes 4-10 weeks to produce measurable AI Overview improvement.
ChatGPT: 8-16+ weeks, less predictable.
ChatGPT’s training data has a cutoff that Anthropic updates periodically, but the schedule is not public. The new web content you create (website, llms.txt, updated listing descriptions) needs to be crawled, included in a training data snapshot, and incorporated in a model update before ChatGPT “knows” about it. This process can take months. The exception is ChatGPT with browsing enabled, which can read your website in real time and improve recommendations within the same 2-6 week window as Perplexity.
Timeline by implementation action
| Action | Propagation time |
|---|---|
| Google Business Profile update | 1-3 weeks |
| Schema.org markup added to website | 2-4 weeks (next crawl + index) |
| llms.txt file added | 1-2 weeks (Perplexity), months (ChatGPT training) |
| NAP consistency across platforms | 4-8 weeks |
| Review volume and quality improvement | 3-6 months for meaningful trend |
The fastest path to first visibility
If you want the fastest first appearance in AI search results, prioritise in this order:
- Claim and complete your Google Business Profile (fastest path to Google AI Overview)
- Add a well-structured website with schema.org markup and llms.txt (fastest path to Perplexity)
- Ensure NAP consistency across your three most important platforms (GBP, TripAdvisor, Booking.com)
These three actions, implemented in a week, can produce measurable Perplexity visibility in 2-4 weeks and Google AI Overview improvement in 6-10 weeks. ChatGPT follows on its own schedule.
Why some properties see faster results
Properties in less competitive markets (smaller cities, niche categories with few competitors) see faster results because the AI has fewer strong alternatives to recommend. A boutique hotel in a mid-sized European city with few well-described boutique competitors may appear in AI recommendations within weeks of a basic implementation.
Properties in highly competitive markets (central London, Paris Marais, major beach destinations) face more competition for AI recommendation slots and may need a more complete implementation and longer timeline before seeing measurable results.
