  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.

Questions & Answers

As answered by people managing Local AI Registry and Nullstack.

What makes your product unique?

Local AI Registry's answer

We measure the one thing local businesses can't see: whether AI assistants can find them and will recommend them. Every business gets an AI Score from 0 to 100, built from eight published signals that are the same for everyone. The math leans on your weakest signal, so one strong area can't hide a weak one. And the score can't be bought. No paid placements, no affiliate links, every input public, every change dated. Businesses can pay us for the work that improves their visibility, never for the score itself.

Why should a person choose your product over its competitors?

Local AI Registry's answer

Most SEO tools show you data and leave the work to you. Most AI-visibility tools track mentions for big brands. We're built for local businesses, and we do both: measure whether ChatGPT, Gemini, Perplexity and Google AI Overviews recommend you, then do the work to fix it. Nearly half our score comes from signals most SEO packages never touch, like YouTube mentions, "best-of" list inclusions and what independent sites say about you. Our methodology is fully public, so you can see exactly what we're improving and why. Check your score free before you decide anything.

How would you describe the primary audience of your product?

Local AI Registry's answer

Owners and managers of local service businesses: med spas, dentists, HVAC, law firms, restaurants, salons, vets and contractors. They're busy, they've usually been burned by an SEO agency before, and they're noticing customers now ask ChatGPT "who's the best near me?" instead of scrolling Google. We also work with multi-location brands and marketing agencies.

What's the story behind your product?

Local AI Registry's answer

Founder Steve Lee once paid an SEO agency tens of thousands of dollars, signed a long contract, and got zero results. That's the short version of why Local AI Registry exists.

Steve spent his career on the brand and digital side: Search at Google in 2015, then VP of Experience and later VP of Innovation at Revance, then Executive Director of Digital and Creative at Evolus. In 2020 he started doing SEO for aesthetic practices and saw how badly the industry serves small businesses: vague reports, long contracts, and agencies that get paid whether you rank or not. In 2024 he launched SEO Aesthetic to fix that for doctors, and it worked.

Then he saw the bigger shift. Customers aren't just Googling anymore. They're asking ChatGPT, Gemini and Perplexity who to trust, and almost no one is built to help a local business show up there. So he built Local AI Registry around everything that first agency never gave him: no long-term contracts, a page-1 guarantee for the keywords you choose within 90 days, and a published, math-based score that shows exactly where you stand before you pay a dollar.

Which are the primary technologies used for building your product?

Local AI Registry's answer

Our scoring engine combines search ranking data from Google and Bing, monthly checks of what ChatGPT, Gemini, Perplexity and Google AI Overviews say about each business, Google Business Profile data, real-user Core Web Vitals, and structured-data validation. Every site is re-crawled every 28 days, and every score is computed the same way, then reviewed by a human.
