We Audited 20 SaaS Homepages for AI Visibility — Here's What We Found
A systematic audit of how well-known SaaS brands are (and aren't) showing up when AI tools like ChatGPT, Claude, and Perplexity answer buyer questions.
Why we ran this audit
The shift from Google to AI-powered search is already here.
When a buyer types "best sales outreach tool" into ChatGPT or Perplexity, the answer doesn't come from a ranked list of blue links. It comes from what the AI was able to crawl, parse, and trust about your site. Most SaaS teams are still optimising for Google's signals — and completely invisible to the new AI search layer.
We used our own AI Visibility Audit tool to run structured audits across 20 SaaS homepages spanning sales, HR, marketing, and B2B software categories. Each site was scored across five dimensions: AI crawler access, structured data, technical foundation, trust & directory signals, and SaaS content depth. The results were stark.
💡 The #1 issue across every site we tested: zero JSON-LD structured data on the homepage. Without it, AI engines cannot reliably parse what the product does, who it's for, or how to cite it in an answer.
How we scored each site
Our tool checks 5 categories, each with weighted sub-signals totalling 100 points.
Deep Dive: lemlist.com
A well-known, well-funded outreach tool — scoring F on AI visibility.
lemlist scores well on technical hygiene and content depth — they have pricing, case studies, and integration content. Their robots.txt doesn't block AI crawlers, and CDN-level access is open. But the score collapses entirely on structured data: 0 out of 25 points. There is no JSON-LD on the homepage. No Organization schema, no SoftwareApplication schema, no Product schema. AI engines have no machine-readable signal to parse what lemlist actually does.
The second gap is the missing llms.txt file — worth 8 additional points. This file is to AI crawlers what robots.txt is to Google: it tells them what pages to prioritise and how to understand the product. Without it, AI crawlers are navigating blindly.

What this means for SaaS marketing in 2026
AI-powered search is not a future threat to prepare for. It is the current buying behaviour of your prospects. When someone asks ChatGPT to compare outreach tools or Perplexity to recommend an HR platform, the tools that get cited are not necessarily the best — they're the ones that gave AI engines the clearest, most structured signal to work with.
The good news from this audit: the technical barriers are low. Every site we audited had solid foundations. Pages load fast, crawlers aren't blocked, content is present. The gap is almost entirely in AI-specific signals — llms.txt and structured data — that most SEO teams haven't prioritised yet because they weren't on the traditional checklist.
That window won't stay open. As more teams catch on, the first-mover advantage in AI visibility will compress. The sites that implement these signals now will be the ones AI recommends by default six months from now.
