When you list a backlink, a guest post or a niche edit on the Zinn® marketplace, you give us the address of the site. You do not give us its authority scores — we measure them ourselves.

What we measure

Four figures, read from the site you named:

• Trust Flow (0-100) - how trustworthy the sites linking to it are.
• Citation Flow (0-100) - how much linking there is, regardless of quality.
• Referring domains - how many distinct domains link to it. This is the number most

buyers judge a domain on.

• Topical Trust Flow (0-100) - how trusted the site is within its own subject area.

A finance blog at 40 is often worth more to a finance client than a general news site at 60.

Why you cannot type them in

A seller-supplied authority score on a marketplace we operate is not a data-entry convenience, it is a fraud vector. If sellers could type their own numbers, the numbers would be worth nothing to buyers - and the numbers are the product. So the form shows them read-only, under "Measured by us", with the date we last checked.

If you try to send one anyway, the API refuses it and tells you why.

When they appear

Measurement runs on a schedule, so a brand-new listing can show no figures for a short while. That is "not measured yet", which is a different thing from "this domain has nothing" - we never write a zero we did not read.

If a domain is not in the index at all, we say so rather than showing zeros.

What buyers see

Every figure on a listing carries the host it was measured against and the date. If you list a subdomain, we measure the subdomain - never its parent - so the score belongs to the thing being sold.
