01 / What the data shows

The pattern is the same on almost every site we score.

more organic trafficmedian monthly visits — AI-visible vs. below-the-bar sites
AI-visible sites
Below the bar

In our 2026 audit, the sites answer engines can read pulled 14× the organic visits of the ones they can’t — a gap that held in every industry tested. Being unreadable isn’t a vanity score. It’s the traffic. Read the study

crawlerWARNING

Googlebot burns its budget on junk.

  • Faceted-nav and parameter URLs eat the crawl
  • The pages that pay you get reached rarely
  • Critical content streams in after LCP
  • Indexation lags publishing by weeks

answer engineCRITICAL

ChatGPT answers your category — without you.

  • No extractable answer for engines to quote
  • Your entity is unresolved: "who is this?"
  • llms.txt missing, schema thin
  • Competitors get cited; you get paraphrased away

youNOTICE

You don't get a warning. You just stop getting found.

  • Traffic flattens; dashboards don't say why
  • "Do more content" stops moving the line
  • Being unreadable to machines is the new invisible
  • The fix is knowable — once you measure it

02 / Who's behind it

An engineer who scored thousands of sites — and published the data.

You can feel the traffic flattening. The dashboards don't say why, and “do more content” isn't an answer. The free scan runs the same engine those studies are built on — so you get a real reading, not a sales pitch.

“Published the data” isn't a figure of speech — it's a 2026 audit of 4,688 service-business sites, scored on the same engine behind this free scan. Read the study

04 / What the free lens measures

The AI-Ready Lens: 17 signals, three buckets.

A pass means an answer engine can read it cleanly; a fail is a discrete, named fix — not a verdict on your business. Every signal is yours to keep.

Does the site clearly describe your business?

05 / What people say about the scan

Small ask. Immediate clarity.

[NEEDS COLLECTION]

“Ran the scan, and for the first time I could see why we weren’t getting cited. Took five minutes. The grade was uncomfortable — and correct.”

“I expected vanity metrics. Instead it named the three things actually costing us traffic and ranked them. No fluff, no upsell theater.”

Methodology is public — the scan is built on the same data study behind our crawl-budget research.

06 / Why now

The engines are deciding either way.

✗ Without the scan

Every month you don’t know your score, the engines keep deciding without you — and the competitor who is extractable gets the citation, the click, and the customer.

$ status → 7 critical · unreadable to 3 of 4 answer engines
✓ With the scan

Know exactly what crawlers and answer engines see, fix the findings that move revenue first, and get found by both — on purpose, not by luck.

$ status → 0 critical · cited by 4 of 4 answer engines
$ ./scan --free

If your traffic is flattening and you can't see why,
the scan is the right next step.

It costs you a URL and 60 seconds. By the way — the scan runs whether or not we ever talk. If the score looks bad enough to act on, the full diagnostic is where that goes.
