# Dr. Karl Jacobs MD: Agent-Direct Score F (38.5%) Site: http://karljacobsmd.com/ Report: https://directindex.org/r/karljacobsmd.com Scanned: 2026-10-24 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.) Dr. Karl Jacobs MD is largely invisible to agents. Some AI assistants are turned away by Dr. Karl Jacobs MD's website. It can't find a menu or price list, so it answers from other sites. It finds a phone number, but no link to book or order online. ## Direct links - Phone: 8587502411 - Address: 4150 Regents Park Row Ste 340, 92037, La Jolla - Languages: German, English, Spanish, French, Indonesian, Italian, Korean, Dutch, Polish, Portuguese, Russian, Turkish, Chinese ## Nearby, also direct Places near Dr. Karl Jacobs MD that take a booking or an order on their own website, with no marketplace in between. - Kolstad Facial Plastic Surgery (40 m): https://directindex.org/r/drkolstad.com - Koorosh Kooros, MD, AGAF (60 m): https://directindex.org/r/unitedmd.com - Life Smiles Dental Care (60 m): https://directindex.org/r/drhayattdmd.com - La Jolla Happy Smiles (70 m): https://directindex.org/r/smilesoflajolla.com ## What to fix first - **No online booking link on the website.** (+13 points) There's only a phone number or WhatsApp, and agents can't use those yet. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add an online appointment page. Guide: https://directindex.org/guides/book-direct-on-your-own-website - **The server turns AI crawlers away at the door.** (+10 points) Requests as GPTBot (http_403), ClaudeBot (http_403), PerplexityBot (http_403) were refused, but a normal browser got the page. That's usually a bot list at the host or in a firewall that the owner never chose. Ask the host to allow these user agents. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing - **No list of services and prices found.** (+7 points) Agents answer 'what do they treat and what does it cost?' from directories instead. Add a page that lists services and prices as text, and link to it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai - **Structured data is incomplete.** (+4 points) Missing: telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant - **No working HTTPS.** (+3 points) The page is only served over plain http. Browsers and agents rank it lower or refuse it. - **No llms.txt.** (no points, but worth doing) Optional for now and cheap to add. It's a short text file that describes the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business ## Fix kit: What to paste Structured data (JSON-LD). Paste it as one block in the page's head, or in the builder's custom code box. Change anything that's wrong. ```html ``` llms.txt. Save as /llms.txt at the root of the site. ``` # Dr. Karl Jacobs MD > organization in 4150 Regents Park Row Ste 340, 92037, La Jolla, San Diego dentists, clinics and vets.
