What the scan measures

24 scored sections, each with the evidence attached.

Every section is scored from what your site actually served, never from what it says about itself.

Why it matters

Agents ask before they act.

AI agents can ask us about your site before they read, quote or buy from it. A clean site gets a better answer; a registered site is named as yours. Register your site → · See the answer for your domain →

Questions about this page

QWhat does the free scan check?
What each AI and search crawler is served compared with a browser, your robots.txt, sitemap and llms.txt, the structured data and claims on the page, your business details against the directories, and speed. Every problem names the page and the evidence.
QDoes scanning change anything on my site?
No. Nothing is installed or written; the scan only reads. Your scan is never published, and any domain can opt out without an account.
QWhat does the fix cover?
Every problem on the list, fixed on the site itself, then re-checked so you see the before and after. One payment of $749, thirty days of monitoring included.
QWhat does Watch add?
We check the site twice a day, date and sign every change, and tell you the day anything breaks. From $29 a month; agencies watch forty client sites on one key.
QCan paying improve my grade?
No. No licence, plan or fix moves a measurement, a finding or a decision. Paying buys the work and the record over time, never a better reading.
