Free backlink checker: what a link from any website is worth

A backlink is worth what the site it comes from can pass on, less the kind of link you can actually get there. Enter any website for its BV score: what one new followed link from it is worth in ranking benefit, in dollars — not what anyone charges for it — worked out by the same model bklink uses to value every link it audits.

Free, no sign-up. You get the BV score, what each type of link from the site would be worth, how it links out, its traffic, its server and its age, with the source of each figure. Reports are public.

What the free backlink checker shows

What a link from the site is worth: the BV score of one new followed link, and what each kind of link it gives, A to D, would be worth.
Links to the site: how many websites link to it, how many of them with nofollow links, how many links in all, their average spam score from 0 to 100, how many IP addresses and subnets they come from, and where on the linking pages the links sit.
The site itself: how it links out, its traffic, its server and network, and its age, each with its source and date.
Everything else on record: its tech stack, page speed, social profiles, which AI crawlers its robots.txt lets in, and more — 195 datapoints in all.

The link counts come from a third-party backlink index, read once a month. They are counts, not a list of every page that links to the site. A site checked for the first time gets them within a day or two, once it has an authority rating.

How to estimate the value of a backlink

How to value a backlink: an Ahrefs guide, and what BV adds

Ahrefs' Domain Rating is its 0 to 100 score of the relative strength of a site's backlink profile, and BV uses it as half of Site Strength, with the site's organic traffic as the other half. BV then prices the kind of link the site gives you, from an editorial citation (×1) to a network link (×0.05). The result is a dollar figure, so two sites with the same Domain Rating can be worth very different amounts.

How to estimate the monetary value of a backlink: traffic, conversion and the calculation

BV's calculation is Site Strength × link type × relevance: a followed editorial link is worth up to $2,265 at strength 100, and half as much every 16.2 points lower. It prices the ranking benefit a link carries, so traffic enters only as half of Site Strength; it does not model conversions or what a visitor is worth to you. What a link earns a business also depends on how its own traffic converts, which only that business knows.

Moz Domain Authority: what is it, and is it a backlink value guide?

Domain Authority is a search engine ranking score developed by Moz: it predicts, from 1 to 100, how likely a site is to rank compared with competitors, and it is not a direct Google ranking factor. It is a score, not a dollar value, and BV does not use it. To value a backlink, BV reads Ahrefs' Domain Rating and the site's traffic, then the kind of link you can get there.

Majestic Trust Flow and Citation Flow in backlink valuation

Trust Flow and Citation Flow are Majestic's metrics, each from 0 to 100: Majestic describes Trust Flow as a quality score that is higher for sites closely linked to trusted seed sites, and Citation Flow as a measure of a URL's link equity from how many sites link to it. BV reads neither. Its valuation rests on Site Strength and the kind of link, and a site whose server shows footprints of one owner is priced as a network link, level D.

Backlinko: how to evaluate backlinks

Backlinko's guide The New Rules of High-Quality Backlinks weighs four things: topical relevance, source credibility, editorial placement and link status, dofollow or nofollow. BV prices the same four its own way: relevance moves a link from ×0.5 for an unrelated site to ×1.25 for the same topic, the site's strength is Site Strength, placement is the link level from A to D, and a nofollow link counts at level C.

How to estimate the value of a backlink with mxverify

Enter the site in the checker: mxverify returns its BV score, what one new followed link from it is worth in dollars, with the level it usually gives and what each level would be worth there. Set that beside the price a publication asks; the score is what the link is worth, not what anyone charges.

the report's limitations

See them on a real report: google.com. What each figure means, and what it cannot tell you: how to read a site report.

The price is what the seller asks. BV is what the link is worth.

BV — backlink value — is what one new followed link from a site is worth to the site it points to, in dollars, before anything about your own site is known. It measures ranking benefit, not cost. Publications set their own prices; the BV score is the figure to set beside a quote, so you know what a backlink is worth before you pay for it. mxverify sells no links, and no site pays to be listed or valued. The score is the one bklink puts on every link in an audit, worked out by BV 2.9.

google.com: up to $1,829, and $183 for the link you can get

google.com is about as strong as a site gets, so a followed editorial link from it would be worth up to $1,829. But Google is a search engine, not a publication: it publishes no guest posts and sells no link placements. The links a business can realistically get there are a business or map listing, or a page on one of Google's services that anyone can make — links Google's own guidance asks sites to mark as user-generated, so neither is an editorial vote. Both are type C, which puts google.com's BV score at $183. The size of the site sets the ceiling; the kind of link decides how much of it you get. Social networks, video platforms, messaging apps and AI assistants are valued the same way, at the link you can actually get.

A link from google.com	Type	Worth
Featured by the company	A · ×1	$1,829
Business or map listing	C · ×0.1	$183
A page it hosts for users	C · ×0.1	$183
Search results and ads	Not a backlink	$0

See google.com's report →

How the value is worked out

1 · Site Strength

0–100: half the site's authority rating, half its organic traffic. It sets the ceiling, halving every 16.2 points below 100.

2 · Link type

A editorial×1
B guest, sponsored×0.5
C neutralised×0.1
D network×0.05

How much of the ceiling the kind of link the site gives keeps: a nofollow link counts as C.

3 · Relevance

×0.5 unrelated×1.25 same topic

To the site the link points to: ×1 on a report, read link by link in a bklink audit.

BV score

$ per link

What one new followed link from the site is worth to rankings. Not a price anyone charges.

google.com: up to $1,829 × C ×0.1 = $183

Two things about the linking site decide it. Site Strength, from 0 to 100, is half the site's link authority rating and half its organic search traffic on a log scale. Strength sets the ceiling: a followed editorial link is worth up to $2,265 at strength 100 and about half as much for every 16 points below that — about $179 at strength 41, where a mid-sized site sits. The scale is pinned to published guest-post asking prices at two points, but the score is what a link is worth to rankings, not what anyone charges. Link type decides how much of that survives, following the distinctions Google's link guidance draws between editorial, sponsored and user-generated links and link schemes:

Type	What it is	Keeps
A	An editorial citation: the site linked because it is useful to its readers.	×1
B	A guest post, sponsored post or paid listing.	×0.5
C	A press release, syndicated copy, profile, forum post, listing — or any nofollow link.	×0.1
D	A link from a site on one owner's network.	×0.05

Where bklink has audited links on a site, the type is read from those links; otherwise mxverify reads the site itself — its homepage and up to ten articles — to see how it links out and whether it sells posts. Each report says which set its type. The full method →

The audits behind the value

bklink has audited 4,447 links on 3,001 publications, 14,912 checks in all. Each audit records whether a link stayed followed, was switched to nofollow, was removed or sat on a dead page. Where bklink has audited links on a site, its BV score takes the link type from them, and its report shows how those links held up.

Link networks: many sites, one owner

Sharing a server does not make sites a network: large hosts put unrelated sites side by side, and one syndication host can carry pages for hundreds of real newspapers. A shared server counts as one owner's network only when the footprints agree — shared private nameservers, registrations within one 90-day window, one registrar, one theme, identical audited purchases. Of 21 shared servers, 12 are networks. A link from a site on one is type D.

Limitations: what this page does not show

3 stated plainly

BV is a model's estimate of what one new followed link is worth to rankings. It is not a price anyone charges, and it does not predict what a link will do for a particular site.
A site Ahrefs does not rate is valued at $0: without a rating there is no link equity to price. It is valued again once it is rated.
Audit figures describe links bklink customers chose to audit, not a random sample of any site's links.
