Spam backlinks spike: triage before you disavow
A sudden pile of junk links triggers panic and, too often, a rushed disavow file. A calm ten-minute triage usually decides the question.
First, what Google has said
Google has said for years that its systems ignore most spammy links, and its link spam update of December 2022 leaned on SpamBrain to neutralise them rather than punish the target. The disavow tool still exists in Search Console, but it is meant for sites with a manual action or a real paid-link history.
Still, a spike deserves a look. Ten minutes. It may be a rival's negative SEO attempt, a hacked site, or your own agency's old work resurfacing. We cannot tell which from a count. So we triage on three facts: how many, how fast, and what anchor.
Keep the record boring. Date, count, top anchors, top linking TLDs and what you decided. Our tld_breakdown action costs 1 credit and shows at a glance whether a spike comes from one odd region. Compare it with last month's run, and see the severity table for the anchor threshold.
If this, then that
| If you see | Then | Why |
|---|---|---|
| A manual action in Search Console | Clean up what you can, disavow the rest, file a reconsideration | This is the case the tool was built for |
| Hundreds of new domains in a week, all with one commercial anchor | Save the list, set a weekly watch, do not disavow yet | Likely ignored, but you need a record if it grows |
| Spike plus a visible traffic drop on the same date | Run the traffic runbook before touching any file | Correlation is not cause, and update dates matter |
| New links on pages you never created | Treat as a hack: check pages, sitemaps and server logs | Spam links may be a symptom, not the problem |
| A few odd links, no change in anchors | Ignore | Every site collects junk |
Red flags that justify action
- More than one new anchor phrase appears across 100 or more domains in a month.
- The anchors are your money keywords, and you never bought them.
- Linking pages sit on hacked sites, with gambling or pharma text.
- The same link pattern appears on your rivals, which suggests a shared vendor.
- You received a manual-action message, not just a bad feeling.
Our index shows that links exist and which anchors they carry. It cannot show intent, nor who built them. We will not tell you a rival did it, and neither should a tool that guesses.
Questions we keep hearing
- How long does Google take to reflect a disavow file?
- There is no published timetable. Google processes the file as it recrawls the linking pages, which can take weeks or months. That is another reason to disavow narrowly and keep a dated record of what you submitted, so you can compare before and after.
- Can a rival wreck my site with toxic links?
- It is possible to attempt it, but Google says its systems are built to ignore such links. Treat a spike as a monitoring event: save the list, watch the anchors weekly, and only escalate if a manual action or a clear traffic loss follows.
- Should I disavow whole domains or single URLs?
- Disavow at the domain level only when a site is entirely junk, for example a hacked network. For mixed sites, list the URLs. If unsure, do nothing and watch for a month; the cost of waiting is lower than the cost of cutting good links.
