Short answer: you don't "rank" — you get cited inside the answer. Here's exactly how businesses get named by ChatGPT, Gemini and Perplexity — and how to check where you stand right now, free.
Traditional SEO is a competition for position in a list. You optimize a page, Google ranks it #1 to #10, and people click. AI search deleted the list. When someone asks ChatGPT, Gemini or Perplexity "who's the best plumber in Austin?" or "what marina software should I use?", they get a single synthesized answer naming two or three businesses. There is no page two. You are either in the answer or invisible.
That changes the goal completely. Instead of chasing keywords and backlinks for a ranking position, you're making your business easy for an AI model to find, verify and quote. This discipline has a name — Answer Engine Optimization (AEO), also called Generative Engine Optimization (GEO). The mechanics below are the core of it.
Mark up your site with Organization, LocalBusiness, Service and FAQ schema. This is the machine-readable label that tells AI exactly who you are, what you offer and where — so it can quote you with confidence instead of guessing.
Open your key pages with a direct, self-contained answer to the real question a customer would ask, then support it. AI models lift clean, quotable answers — burying the point three paragraphs down means it never gets cited.
Add an llms.txt file that summarizes your business for language models, and make sure your robots.txt isn't blocking GPTBot, Google-Extended or PerplexityBot. Many sites accidentally lock the AI crawlers out and wonder why they're invisible.
Same name, address, phone, hours and description on your site, your Google Business Profile and every directory. Conflicting details make AI distrust all of them — and recommend the competitor whose data is consistent.
ChatGPT and Perplexity build answers from sources they trust — review sites, directories and "best of" roundups for your niche. Getting listed in those is how you enter the pool the AI is quoting from.
Ask ChatGPT, Gemini and Perplexity the exact questions your customers ask, and track whether you get named. Re-test after each change so you know what actually moved the needle.
That last step is the one most businesses skip — and it's the one that tells you whether any of this is working. That's the part AnswerGap automates.
Enter your site and industry. We ask ChatGPT, Gemini and Perplexity 20 real customer questions about your niche and show your mention rate, who gets recommended instead of you, and the exact signals you're missing — in about 60 seconds.
