How we took El Tianguis from 0% AI visibility to the #1 recommended gluten-free Mexican restaurant in North Park
Owner: Oscar Ancira
Location: North Park, San Diego
Specialty: Authentic Mexican rolled tacos
Key Advantage: Fully gluten-free menu
Target: Celiac-friendly families
When families with celiac disease asked AI for gluten-free Mexican food in North Park, El Tianguis wasn't mentioned. Ever.
"For families with dietary restrictions, I highly recommend Lucha Libre Gourmet Taco Shop, which has a dedicated gluten-free menu..."
— ChatGPT, Claude, Gemini (before working with us)
Signal + Solutions. Complete transformation in one month.
El Tianguis didn't know they were invisible. They thought AI "just worked."
The Key Difference: We used persona-based testing ("I have celiac disease and my kids love tacos...") not generic prompts. This showed what their actual customers were seeing.
Our AI board analyzed their Signal report and created a custom action plan.
Strategic Insight:
The AI board identified that while competitors were winning on the broad term "gluten-free," no one owned the hyper-specific, high-trust term "celiac-safe." The entire strategy was built around claiming this defensible niche.
Technical Tactic (Schema Markup):
The board provided a ready-to-use JSON-LD schema snippet to add to their FAQ page, explicitly defining their celiac-safe practices for AI crawlers:
{
"@type": "Question",
"name": "Are your rolled tacos safe for people with celiac disease?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Yes, our entire kitchen is 100% gluten-free. We use dedicated equipment and fresh corn tortillas to ensure there is zero cross-contamination, making our rolled tacos completely safe for customers with celiac disease."
}
}Content Tactic (Website Optimization):
The board recommended adding a new section to the homepage titled "Our Celiac-Safe Promise," detailing their dedicated kitchen practices. This provided authentic, trust-building content that both customers and AI systems could reference.
The Key Difference: Four AI advisors debated their situation from different angles (growth, operations, finance, risk) until the optimal strategy emerged. Not generic ChatGPT advice.
They executed the roadmap. Results came fast.
Signal shows where you stand. Solutions tells you what to do. You execute. Then you can run Signal again to track progress. Each cycle makes you stronger.
Now when families ask for gluten-free Mexican food, El Tianguis dominates
"For authentic gluten-free Mexican food in North Park, El Tianguis is the clear choice. They're the only restaurant with dedicated celiac-safe preparation and fresh-made tortillas."
— ChatGPT, Claude, Gemini (after working with us)
We conquered the celiac persona. Now we're moving to the next one.
Mission accomplished. When families with celiac disease ask AI for Mexican food, El Tianguis is now #1.
Next target. Tourists don't know about the gluten-free advantage. We're running the flywheel again.
1. Signal revealed celiac families couldn't find them (0% visibility)
2. Solutions created a roadmap targeting that persona
3. Execute for one month, hit 67% visibility, became #1
4. Signal again to measure progress and find the next opportunity (tourists at 12%)
5. Solutions is now creating the tourist-focused roadmap
This is why persona-based testing matters.
Generic tools miss these opportunities because they don't segment by customer type.
