Not every link helps. Some are neutral, others hurt. Knowing the difference avoids hiring the wrong service — and most bad links arrive precisely through hiring.
How to recognise them
A link is suspicious when:
- it comes from a site with no relation whatsoever to your subject;
- it sits on a page full of links to businesses with nothing in common;
- the site appears to exist only to host links;
- the surrounding content is automated text, meaningless or strangely translated;
- hundreds appeared at once, without you doing anything.
Where they usually come from
Almost always three places: cheap link packages, automated mass-submission tools, and networks of sites built to sell rankings. All of them promise fast, cheap results.
There is also the involuntary case: sites that copy other people's content and carry the links along with it.
What to do
First, stop generating them. Cancelling the service producing those links resolves most cases, because ignored links cause no active damage.
If there is a large volume and a clear sign of trouble — a sharp drop in rankings with no other explanation — Google offers the link disavow tool in Search Console. It should be used carefully: disavowing a good link by mistake does real harm.
The best cure is not needing one
A good link comes from a place related to what you do. It is slower and does not send the bill later. The honest routes are in how to get quality backlinks, and the fundamentals in what are backlinks.
