Negative SEO is any deliberate attempt by someone else to hurt a website's search rankings. The best-known example is a competitor pointing thousands of spammy, low-quality links at your site, hoping Google will think you're manipulating rankings. Other forms include copying your content across the web, hacking your site or posting fake reviews.
For a business, the fear of negative SEO often causes more stress than the attacks themselves. Google says it works hard to make sure actions on third-party sites don't negatively affect a website, and it ignores most spammy links on its own. Knowing which threats are real, and which aren't, helps you spend your time on what actually protects your site.
What is negative SEO?
Negative SEO describes tactics aimed at damaging another site's visibility in search, rather than improving your own. It borrows methods from black hat SEO but points them at a target. Common forms include:
- Link spam attacks: building large numbers of low-quality or irrelevant backlinks to a site, often with spammy anchor text
- Content scraping: copying a site's pages and publishing them elsewhere to create duplicate content
- Hacking: breaking into a site to add spam pages, hidden links or redirects, or to change robots and indexing settings
- Fake reviews: posting false negative reviews on a Google Business Profile or other review sites
- Bogus removal requests: filing false complaints to get a site's links or pages taken down
The term isn't an official Google category. Google's documentation doesn't use the phrase "negative SEO," but it covers the underlying issues, such as link spam, hacked content and links you didn't build yourself.
Why negative SEO matters
Most link attacks don't work. Google's disavow documentation says that in most cases, Google can assess which links to trust without additional guidance, and that Google works very hard to make sure actions on third-party sites don't negatively affect a website. In 2022, Google's John Mueller told a site owner worried about spammy links, "I'd just ignore them," as reported by Search Engine Journal.
Hacking is the real danger. A hacked site can be filled with spam, cloaked pages or malicious redirects. Google's spam policies treat hacked content as a violation, and sites with spam can rank lower or disappear from results. Unlike spammy links, this needs fast action.
Reputation attacks affect AI answers, too. AI assistants often draw on reviews, forums and third-party pages when describing a business. Fake reviews or false information spread across the web can shape how AI tools summarize your brand, which is why monitoring your AI brand sentiment is useful.
Misdiagnosis wastes time. Ranking drops are usually caused by algorithm updates, technical problems or stronger competitors, not attacks. Blaming negative SEO can distract from the real fix.
How negative SEO works
Link-based attacks
An attacker buys or automates thousands of links from low-quality sites, link farms or spammy directories, sometimes with keyword-heavy or adult anchor text. The idea is to make your link profile look manipulative. Google's systems are designed to discount links like these, which is why most such attacks have little effect.
Content and technical attacks
Scrapers copy your content to other domains. Hackers may inject spam pages, hidden links or redirects, or change settings to block crawlers. Google notes that hackers often use cloaking so the site owner doesn't notice the hack. These attacks can cause real damage if they go unnoticed.
Reputation attacks
Fake reviews, false listings and misleading posts target what customers and AI tools read about you. They don't change your rankings directly, but they can hurt trust and conversions.
How to protect your site from negative SEO
- Secure your site first. Keep your CMS, plugins and themes updated, remove unused ones, use strong passwords with multi-factor login and keep backups.
- Verify Google Search Console. Search Console alerts you to security issues and manual actions, and shows your top linking sites.
- Monitor your link profile. Check new referring domains occasionally with a backlink tool. Sudden spikes are worth a look, but they usually don't need action.
- Use the disavow tool only when it fits. Google says to disavow links only if you have a considerable number of spammy, artificial or low-quality links and they have caused, or likely will cause, a manual action. See disavow tool.
- Watch for copied content. If a scraper outranks you or copies large parts of your site, you can file a legal removal request with Google.
- Monitor and respond to reviews. Reply professionally to negative reviews, and report reviews that break the platform's policies.
- Report spam. Google invites anyone who believes a site is violating its spam policies to report it through its search quality user report.
Common mistakes and misconceptions
- "Every spammy link is an attack." Most sites collect random low-quality links over time. That's normal web noise, not a targeted campaign.
- "I need to disavow every bad link." Google says most sites don't need the disavow tool. Overusing it can mean disavowing links that were actually helping.
- "A ranking drop means someone attacked me." Check for core updates, technical issues, lost links and competitor changes first.
- "Negative SEO can't happen." Link attacks rarely work, but hacking, scraping and fake reviews can cause real harm. Security and monitoring still matter.
Negative SEO vs. black hat SEO
Black hat SEO uses manipulative tactics to boost your own rankings, such as buying links or stuffing keywords. Negative SEO uses similar tactics against someone else's site, hoping to trigger penalties or ranking drops. The tactics overlap, but the target is different. In both cases, Google's position is the same: it tries to ignore manipulative signals and protect sites from actions taken by third parties.
How Butter approaches negative SEO
At Butter, we start by ruling out the more common causes of a ranking drop, such as technical issues, indexing problems, content changes or algorithm updates. When we review a client's link profile as part of our off-page work, we look for real patterns rather than reacting to every odd link.
We recommend disavowing only when Google's own criteria apply, and we focus on what protects a business most: a secure site, clean indexing, steady monitoring and earning quality coverage over time. Our AI prompt testing also helps us spot when false or negative information starts showing up in AI answers about a client.
Frequently asked questions
Can a competitor hurt my rankings with bad links?
It's unlikely. Google says it can assess which links to trust in most cases and works hard to make sure actions on third-party sites don't negatively affect a website.
Should I disavow spammy links pointing to my site?
Usually not. Google recommends disavowing only if you have a considerable number of spammy or artificial links and they have caused, or likely will cause, a manual action.
What is the most serious type of negative SEO?
Hacking is usually the most damaging, because attackers can add spam, hidden links or redirects to your actual site. Keeping your site secure and watching Search Console's security alerts are the best defenses.
How do I know if I'm a victim of negative SEO?
Look for sudden spikes in spammy links, unfamiliar pages indexed on your domain, security warnings in Search Console or a wave of fake reviews. Rule out algorithm updates and technical issues before assuming an attack.
