Can the assistants read your site at all?
Check robots.txt for blocks on OAI-SearchBot, Claude-SearchBot and PerplexityBot. These are the live-search crawlers, and blocking them removes you from consideration entirely.
If you want us to handle the checks and website changes, see what our AI SEO agency in Calgary includes. The service page separates access checks from the engines we measure.
This is the first thing to check because it's binary and it's common. A site that blocks the live-search crawlers cannot be cited, no matter how good it is. The blocks are almost never deliberate, they arrive with a security plugin, a CDN bot-protection default, or a robots.txt copied from a template written when 'AI crawler' meant something else.
Worth separating clearly: the training crawlers (GPTBot and similar) are a genuine privacy decision and reasonable people block them. The live-search crawlers are the ones that fetch a page in order to answer a question being asked right now. Blocking those costs you the citation and buys you nothing.
