DeepSeek is likely pulling outdated or mismatched information from cached web pages, third-party directories, or aggregator sites that still describe your properties incorrectly. Updating your own site won't immediately override what's already indexed elsewhere, and DeepSeek may prioritize older or external sources over recent on-domain content.
Start by auditing where these claims originate. Search for your brand name plus "spa" and "wine tasting" on Google, Bing, and in travel aggregators like TripAdvisor, Booking.com, and Google My Business. You'll likely find at least one outdated listing or competitor profile that's feeding the hallucination. Claim and correct those profiles first—this is the fastest lever.
Next, add explicit negative schema markup to your homepage. Use schema.org/Organization with a structured description of what you *don't* offer, or add a FAQ section with schema.org/FAQPage that directly addresses common misconceptions ("Do you have a spa?" → "No"). This won't immediately stop DeepSeek, but it gives newer crawlers clearer signals.
Finally, monitor by searching your brand in DeepSeek weekly for the next month. The false claims should fade as external directories update and as DeepSeek's next refresh cycle picks up corrected data. If they persist after 4–6 weeks, the source is likely a single high-authority directory or review site that needs manual correction.
