The PBN footprint checker

What publicly ties your sites together, how the score works, and how to use the fix for each finding.

Zinn®, our Viking, reading his checklist beside an index of articles with one open.

Footprint checker (in the sidebar) checks a set of your sites for the traces anyone can see that tie them to one owner, and tells you how to break each link.

What is checked

Every site you host with us, always, on every plan. Sites you host with other providers are included too once you add a site pack: open Sites, enter the domain and press Add site. Checks run on their own — monthly or weekly, depending on your plan — and Check now starts one whenever you have changed something.

Reading the score

The score is out of 100 for the whole set, with a grade from A to E. 100 means nothing we could see ties your sites together. Each finding costs more the more serious it is and the more of your sites it covers. The line under the score shows how it has moved between checks.

The four tabs

Risks lists every finding, most serious first. Open one to see which sites it involves, what it means and how to fix it; some have a button that takes you straight to the fix. Findings that come from our own platform are listed apart, under We are handling these — they are ours to fix and never lower your score.

Site pairs shows the two sites most closely tied together, strongest first. Choose a site to see everything it is tied to.

Sites shows what was read from each site on the last check, and your allowance of sites hosted elsewhere.

History lists every check, automatic or started by you, and what each one covered.

Checking one site, or comparing a few

On Sites, tick one site and press Check this site to check it on its own, or tick several and press the Compare button to check just those against each other. The result opens like any other check. You can only choose sites that are yours: hosted with us, or added as hosted elsewhere. These count as check-now runs.

One site's history

Press History beside a site to see every finished check that covered it, whether it could be read each time, and which findings named it. Open takes you to that check.

Keeping a copy

Download as CSV saves the check you are looking at as a spreadsheet file, in your own language: one row for each finding and site, with what it means and how to fix it.

When we e-mail you

Only when a scheduled check comes out worse than the one before — a lower score, or a kind of finding that was not there last time. The e-mail gives the two scores and how many links there are to fix; the detail stays on this screen. A steady or better score sends nothing, and neither does a check you started yourself. If you add, rename or remove a site, the next scheduled check is brought forward so the change is picked up within about an hour — at most once a day.

Check-now runs

Your plan includes a number each month. Automatic checks never count, and a check that could not read any of your sites is not counted either. If an invoice is unpaid, automatic checks pause and pick up again once it is settled.
