Backlink Sheet Checker

Yes. The checker reads both the column names and the values: a column of URLs on many different sites is where links were placed, and a column of URLs mostly on one site is your target. You can change any guess before the check runs.

Link builders often keep directory and forum logins next to the links. Any column that looks like a password, API key, token, 2FA code or card number is removed in your browser and never sent. Stray keys in other columns are blanked cell by cell.

The link is gone from the page, the page returns 404 or 410 or now redirects elsewhere, or the whole site is down. A 403 or 429 is shown as "check by hand", because many sites turn away automated visits but work fine in a browser. On a saved sheet, a link that was working and then misses is checked again a few hours later, and only counts as lost if it misses twice. A site that was down for ten minutes will not send you an alert.

The link is on the page, but Google is told to skip that page: it is set to noindex, robots.txt blocks Google from it, or it names a different URL as its canonical. The link is there for readers and passes nothing to your rankings.

Type your website in the "Your website" box and every row is checked for a link to it. With no target at all, only the page itself is checked.

Visitors can check 50 rows at a time. Signed-in users can check 500 and save the sheet to the Backlink Monitor, re-checked daily, weekly, every two weeks or monthly, and told when a link disappears.

No. The check reads the page as it is first served, the way many crawlers do. When a page is an empty shell that scripts fill in, the row says "check by hand" instead of "removed", so open it to confirm.

A sheet is fine for a one-off check. For links you need to keep, our post on tracking backlinks in spreadsheets explains what goes wrong, and the backlink manager re-checks every link in a project each week.
