What is negative SEO?
Negative SEO is the use of black hat tactics against a competitor’s site to make it rank lower. The usual forms are pointing thousands of spammy links at the site, hacking it to inject spam, copying its content elsewhere, posting fake negative reviews and filing false removal requests.
It is labelled black hat because it is done to others, not because the target did anything wrong. Google’s position is that negative SEO is rarely effective. Its systems are built to ignore most spammy links rather than count them against a site, and Google has said for years that it works hard to stop third parties harming sites this way.
The forms that do cause harm are the ones that change the target site itself or its reputation directly: hacking, which can get spam pages indexed under the site’s name, and fake reviews on its Google Business Profile.
Why negative SEO matters
Fear of negative SEO drives a lot of bad decisions, mainly mass disavowing of every odd link. Most sites collect some junk links naturally, and Google already ignores them. Disavowing good links by mistake can do more damage than the attack.
Knowing the real risks lets you spend effort where it counts: site security, review monitoring and checking Search Console, rather than chasing every spam domain in your link profile.
Risks of negative SEO
- For the attacker: hacking or fake reviews can break computer misuse and consumer protection laws, and fake removal requests can amount to fraud.
- For the target: hacked pages or injected spam can trigger a security warning or manual action until cleaned up.
- For the target: fake negative reviews can hurt local rankings and conversions until they are removed.
- Wasted effort on both sides: Google ignores most spammy links, so link attacks and panicked mass disavows usually achieve nothing.
How to protect against negative SEO
- Keep the site secure: update the CMS and plugins, use strong passwords and two-factor login, and check the Security issues report in Search Console.
- Watch your backlink profile monthly for sudden spikes of spammy links, but do not act on them unless something changes.
- Use the disavow tool only when you have a manual action for unnatural links, or when you believe a large set of spammy links is likely to cause one. Google says most sites never need it.
- Monitor your reviews and report fake ones through Google Business Profile.
- If your content is copied and outranks you, file a copyright removal request.
- Report spam to Google through its spam report form.
Negative SEO FAQ
Does negative SEO work?
Rarely, through links. Google says it ignores most spammy links. Hacking and fake reviews can do real harm, which is why security and review monitoring matter more.
Should I disavow spammy links pointing to my site?
Usually not. Google suggests disavowing only if you have, or expect, a manual action for unnatural links, for example after buying links in the past.
How do I know if I am under a negative SEO attack?
Signs include a sudden flood of spammy links with explicit anchors, pages appearing on your site that you did not create, or a burst of one-star reviews from new accounts.
