Perplexity is pulling your clinic data from a source—likely Google Business Profile, a local directory, or your website—but that source is incomplete or inconsistent across where Perplexity checks. Start by auditing your Google Business Profile this week: verify your phone, hours, address, and website are all filled in and match exactly across your own site's footer and schema markup.
Next, check your local schema markup. Add or update schema.org/LocalBusiness on your homepage with telephone, openingHoursSpecification, and areaServed. Perplexity doesn't crawl as aggressively as Google, but it does index structured data. If you're on a platform like Vet Street or Care Credit, make sure your clinic's profile there is complete too—Perplexity may cite those.
To verify the fix worked, search Perplexity for variations of your query in a week or two. Look for whether your phone and hours now appear alongside your name. If they still don't, try the search in an incognito window to bypass cache, and compare your data completeness to one competitor that does show hours. That gap will tell you which source Perplexity favors for your market.
