Why it matters on an HVAC site
It is routinely presented to contractors as maintenance. It is not maintenance; it is a remedy for a specific situation, which is a manual action or a known history of buying links.
A disavow file built from a tool’s toxicity report can remove links that were helping, and there is no undo that works on the original timescale.
How to check it yourself
- Check Search Console for a manual action. No manual action is the normal state and means there is nothing to remedy.
- Establish whether links were deliberately built, from the anchor profile and from asking the previous agency.
- If a file is warranted, build it from links you know were bought rather than from a vendor score.
Worked through in numbers
A contractor arrives with a disavow file containing 2,900 domains, uploaded by a previous agency in 2022.
No manual action existed then or now. Reviewing a sample of the 2,900 found the county newspaper, a manufacturer dealer page and two supplier listings among them, all disavowed automatically because a tool scored them low.
The file was replaced with one containing the 40 domains from a genuine paid-link campaign the owner confirmed. The three legitimate links were already lost to time, which is the part that could not be undone.
