Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.

Assistants

What assistants answer

Not asked yet. Assistants are asked about the top-ranked businesses in each city index, and about every claimed business the moment it is claimed; claim this page to be included.

The climb

With the three fixes above (No ticket link on the website; robots.txt blocks GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, ChatGPT-User, Claude-User, Perplexity-User; No tickets and prices found) the score would be about 86.2%: first of 45 in San Diego tours, attractions and museums.

Peers are the businesses of the same index with a reachable site, latest scan of each; the rank uses the index's current ranking.

Findings

What to fix first

  1. No ticket link on the website +13 points

    Only a phone number or WhatsApp, which agents cannot use yet. If you take bookings or orders through a platform, link to it from the site so an agent can find it. Add a ticket or booking page. How to fix it

  2. robots.txt blocks GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, ChatGPT-User, Claude-User, Perplexity-User +10 points

    These are the crawlers behind ChatGPT, Claude, Perplexity and Google's AI features. Remove the Disallow lines for them, or add explicit Allow rules. How to fix it

  3. No tickets and prices found +7 points

    Agents answer 'what does it cost and when' from marketplaces instead. Add a page with tickets, times and prices as text and link it from the homepage. How to fix it

  4. Structured data is incomplete +6 points

    Missing: address, telephone, opening hours. How to fix it

  5. No llms.txt no points, still worth doing

    Optional today, cheap to add: a short text file describing the business for language models. How to fix it
