Negative SEO is an attempt to harm a competitor rankings on purpose. Most of it does not work, but some tactics genuinely do. Here is the difference.
Negative SEO is a deliberate attempt to damage another site’s search performance. Spam links pointed at a competitor, scraped copies of their content, fake reviews, or an outright hack.
Most of it does not work. Some of it does and the quieter tactics cause real harm.
The link attack, and why it usually fails
The classic version is blasting thousands of junk links at a rival, hoping Google punishes them. Google spent years building defences against exactly this, for the obvious reason that a search engine you could sabotage this cheaply would be worthless.
In practice, obvious spam links get ignored. Google’s own guidance is that most sites should never touch the disavow tool, and that holds even when your link report looks alarming. If you see a spike of Russian pharmacy links, the correct response is usually to note it and carry on.
The exception is a site with an already shaky link profile. If someone bought links for you in 2018 and a competitor adds a fresh layer of spam on top, the combination can be enough to draw a manual review. That is a reason to clean up your own history, not a reason to panic about theirs.
The attacks that actually work
These do damage, and they get far less attention than link spam.
- Content scraping. Copies of your pages published elsewhere. Rarely outranks you, but it dilutes and wastes crawl budget, and occasionally the copy wins on a thin page.
- Hacking. Injected spam pages, hidden links or redirects. This causes genuine, immediate ranking loss and sometimes a malware warning in the results.
- Fake negative reviews. A coordinated run of one-star reviews hits local pack rankings and conversion rate at the same time. The conversion damage is the worse half.
- Fake Business Profile edits. Anyone can suggest a change to your listing. Wrong opening hours or a wrong phone number can sit live for days.
- Malicious redirect claims and false DMCA takedowns. Filed against your pages to get them removed from the index while you appeal.
What to actually do about it
Monitoring beats reacting. Set up Search Console alerts, watch your referring domain count monthly rather than daily, keep an eye on review velocity, and turn on notifications for Business Profile edits. Most attacks are visible within a week if anyone is looking.
Security is the higher value work. Two-factor authentication on your CMS, your registrar and your Business Profile closes off the attacks that genuinely hurt. A strong, established link profile is also its own defence: junk links look like noise against a background of real coverage rather than the whole picture.
That is the honest answer for most businesses worried about this. Build enough real authority that spam cannot shift the balance. Our digital PR team works on that side of it rather than the disavow file.
Common questions
Can a competitor really hurt my rankings with spam links?
It is difficult and usually fails. Google discounts obvious spam rather than penalising the target. The risk rises only if your existing profile already contains links you would rather Google did not look at closely.
Should I disavow links that appear suddenly?
Generally no. Google advises against routine disavowing, and removing links you did not fully assess can cost you ones that were helping. Disavow when you have a manual action naming links, or when you know links were bought for you.
How do I deal with fake reviews?
Report each one through your Business Profile with a short factual reason, respond publicly and calmly, and keep collecting genuine reviews. Volume of real feedback dilutes an attack faster than the reporting process resolves it.
What if someone copies my content?
Check whether you are still ranking first. If you are, ignore it. If the copy is outranking you, file a DMCA removal request with Google and contact the host directly, which is often quicker.
