attack library13 Types of Negative SEO Attacks
Every negative SEO attack falls into one of three groups: off-site attacks that happen on other websites, on-site attacks that change your own site or server, and reputation attacks that use Google's tools, review platforms and your brand name against you. Here's how each one works, how to spot it and how to fix it.

Toxic link blasts
+4,812 links · 212 new domains · 9 days
The attacker points thousands of spammy links at your site from link farms, hacked pages, comment spam and auto-generated sites. The hope is that Google decides you bought them and lowers your rankings.
- // warning_signs
- A sudden jump in linking domains in Search Console or your backlink tool, mostly from unrelated, low-quality or foreign-language sites.
- // how_to_fix
- Record the dates and keep watching. Google is built to ignore most of these links, so usually no action is needed. Use the disavow tool only if you get a manual action for unnatural links, or the attack is huge and clearly matches a ranking drop.

Anchor text bombing
anchor: "buy cheap pills" ×1,206
A variation of the link blast. The links use exact-match money keywords, or adult, gambling and pharma words, to make your link profile look manipulated or to tie your brand to spam topics.
- // warning_signs
- Your anchor text report fills up with keywords you never targeted or with off-topic adult and gambling terms.
- // how_to_fix
- The same as link blasts: document, monitor Search Console for a manual action, and disavow whole domains only in extreme, clearly harmful cases.

Content scraping and duplication
"your exact sentence" → found on 14 domains
Bots copy your pages and republish them on other sites, sometimes within minutes. The goal is to make Google see the copy first, or so often that your original looks like the duplicate.
- // warning_signs
- Exact sentences from your pages show up in Google on other domains, or copies appear right after you publish.
- // how_to_fix
- Use self-referencing canonical tags, a clean sitemap and strong internal links so Google finds your version first. If a copy outranks you, send a copyright (DMCA) removal request with links to both versions.

Fake DMCA takedowns
notice: /services/ removed · claimant: unknown
Someone files a false copyright complaint claiming your page copied theirs, often using a backdated copy of your own text. Google may remove the URL from search while the claim is reviewed, so a key page can vanish overnight.
- // warning_signs
- A "Notice of DMCA removal" email or Search Console message, an important page missing from Google, or a complaint about your URL in the Lumen database.
- // how_to_fix
- File a counter-notice through Google's form with proof that the content is yours. If the claimant doesn't start a lawsuit, the page is normally restored after the legal waiting period of about 10 to 14 business days.

Hacking and spam injection
+412 pages /?p=cheap-* · lang: ja
The attacker gets in through an outdated plugin, a weak password or a vulnerable theme. Then they add hidden links, create thousands of spam pages, or show spam only to Googlebot (cloaking) so you don't notice.
- // warning_signs
- "This site may be hacked" under your result, a warning in the Security issues report, pages in a site: search that you never created, unknown admin users or a sudden jump in indexed pages.
- // how_to_fix
- Clean every infected file, update and patch, change all passwords and remove unknown users. Return 410 or 404 for the spam URLs, then request a review in Search Console. Reviews for hacked spam can take several weeks.
06on-sitedamage
Malware and sneaky redirects
mobile + google referrer → 302 → scam-site
Injected code sends some visitors, often only mobile users or people coming from Google, to scam, adult or malware sites. Google and browsers then warn people away from your site.
- // warning_signs
- A red browser warning page, a malware or social engineering notice in the Security issues report, or customers saying your site sends them somewhere else.
- // how_to_fix
- Remove the malicious code and its back door, scan the whole server, harden logins and request a review. Malware reviews usually take a few days once the site is fully clean.
07off-sitedamage
Fake link removal requests
The attacker emails websites that link to you, pretends to be you, and asks them to remove your best backlinks. It's quiet, cheap and hard to spot.
- // warning_signs
- Strong backlinks disappear without explanation, or a site owner mentions the request you supposedly sent.
- // how_to_fix
- Track your most valuable links, always contact partners from your own domain email, and let key sites know you'll never ask them to remove a link from a free email address.
08reputationdamage
Review bombing
★1 ×9 · 48 hours · 7 brand-new accounts
A wave of fake one-star reviews hits your Google Business Profile, Trustpilot or other review sites, often written with AI so each one looks different. It hurts trust, clicks and local rankings.
- // warning_signs
- Several low ratings in a short time from new or empty accounts, with no matching customer, booking or invoice, and similar wording.
- // how_to_fix
- Reply calmly, report each review under Google's fake engagement policy, keep a record of the pattern and escalate to Business Profile support. Keep genuine reviews coming from real customers.

Google Business Profile sabotage
suggested edit: status → "Permanently closed"
Anyone can suggest edits to a Business Profile. Attackers mark you as closed, change your phone number, hours, website or category, create duplicate listings, or report your profile so it gets suspended.
- // warning_signs
- Your profile suddenly shows the wrong details, says you're closed, has a pending "Google update" or is suspended.
- // how_to_fix
- Check your profile every week, reject wrong updates straight away, keep it verified and appeal any suspension with proof such as signage photos and business documents.

Smear campaigns and fake news
"yourbrand scam" → forum post ranks #3
Fake articles, "Is this company a scam?" posts, fake complaint pages and AI-written listicles are published and pushed up for your brand name, so customers and AI assistants find them first.
- // warning_signs
- New negative results when you search your brand name, AI answers repeating claims you've never seen, or fewer branded clicks and calls.
- // how_to_fix
- Work through the removal routes: the site owner, the platform's own policies and legal routes where the content is false. Where removal isn't possible, push it down with stronger pages you control. See the removal service.

Impersonation and lookalike domains
yourbrand-official.shop · registered 3 days ago
Fake social profiles or a cloned website on a lookalike domain use your name and logo to scam your customers or steal your branded traffic.
- // warning_signs
- Customers ask about orders or messages you never sent, or profiles appear with your logo and photos.
- // how_to_fix
- Report impersonation to each platform, send abuse reports to the registrar and host, and ask a lawyer about a domain dispute (UDRP) where you own the trademark.

Bot floods and server overload
requests: 48k/min · 503 errors ↑
Fake traffic or a DDoS attack makes your server slow or unavailable. Googlebot meets errors, crawls less, and your analytics fill with junk visits.
- // warning_signs
- Server errors in the Crawl stats report, a slow or crashing site, and huge traffic spikes from one country or network with no engagement.
- // how_to_fix
- Put the site behind a CDN with a firewall, add rate limits, ask your host for help and filter bot traffic out of your analytics.

Internal search and URL parameter spam
/?s=casino+bonus · indexed ×2,340
The attacker links to your internal search pages or URL parameters with spam words in them, so Google finds thousands of junk pages on your domain that show spam text.
- // warning_signs
- Indexed URLs with ?s= or odd parameters in the Pages report, often containing gambling, adult or pharma words.
- // how_to_fix
- Add noindex to internal search results, keep them out of your sitemap and never link to them. Once the junk has dropped out of Google, you can block the search path in robots.txt.
// damage = how much harm the attack can do if nobody acts. log lines are examples
