Is Someone Pointing Spam Links at Your Website? How to Tell

It starts with a weird feeling

You check your analytics one morning and something's off. Traffic is down — not dramatically, but enough to notice. Your rankings for a couple of key terms have slipped from page one to page two. You haven't changed anything on the site. No algorithm update that you know of.

So you dig into your backlink profile. And there they are: dozens, maybe hundreds, of new links from websites you've never heard of. Blogspot blogs with gibberish names. Foreign-language directories. Pages stuffed with outbound links to totally unrelated sites. None of it makes any sense.

Welcome to negative SEO.

What negative SEO actually is

Negative SEO is when someone deliberately builds low-quality backlinks to your website, hoping that Google will see the spam and penalise you for it. The idea is simple: make it look like you've been doing dodgy link building, so Google drops your rankings.

It sounds dramatic, and honestly, it's not as common as some SEO forums would have you believe. Google has gotten much better at ignoring spam links automatically. But it does still happen, particularly in competitive niches where knocking a competitor down a few spots is worth real money.

The typical attack looks like this: someone buys a cheap negative SEO package (you can find them for under £10 on sketchy forums) and points thousands of links from link farms, scraped blogs, and spam directories at your domain. They might use exact-match anchor text like "buy cheap widgets" to make it look even more unnatural.

How to tell if you're being targeted

Not every spike in spam backlinks is an attack. Websites naturally accumulate junk links over time. The difference between normal spam and a deliberate attack comes down to a few patterns:

Volume and speed. Normal spam trickles in — a few links a week from random directories. An attack looks like hundreds or thousands of links appearing within days. If your backlink count jumps by 500% in a week and you haven't done anything to cause it, that's a red flag. Patterns in the linking domains. Attack links tend to follow templates. Same hosting provider, similar domain names, identical page layouts. If you see 200 new links and 180 of them are from .xyz domains registered in the last month, someone is probably behind it. Suspicious anchor text. Attackers often use aggressive commercial anchor text — exact-match keywords stuffed with phrases like "best" or "buy" or "cheap." If your natural anchor text is mostly your brand name and URLs, and suddenly half your new links say "buy discount plumbing supplies London," something is off. No corresponding content. Legitimate backlinks usually come from pages with real content that references your site in context. Attack links come from pages with no meaningful content — just lists of outbound links or auto-generated text.

What you should actually do about it

First, don't panic. A single batch of spam links is unlikely to destroy your rankings. Google's algorithm is quite good at spotting and ignoring obviously fake links. The danger is when spam accumulates over months without being addressed.

Here's the practical response:

Document everything. Screenshot the spike. Export your backlink profile. Note the date range when the new links appeared. If you ever need to file a reconsideration request with Google, this paper trail matters. Audit and classify. Run a proper backlink audit to separate the spam from your legitimate links. You need to know exactly which domains are problematic before you can do anything about them. Build a disavow file. For the toxic domains you've identified, create a disavow file and upload it to Google Search Console. This tells Google to ignore those links when evaluating your site. It won't fix things overnight — Google needs to recrawl those domains, which takes weeks — but it stops the bleeding. Keep monitoring. Attacks don't always stop after one wave. Set up regular monitoring so you catch new spam links quickly. Monthly checks are the minimum; weekly is better if you're in a competitive niche.

The honest truth about negative SEO

Most ranking drops aren't caused by negative SEO. They're caused by algorithm updates, technical issues, better competitors, or content that's gone stale. Before blaming an attacker, rule out the boring explanations first. And if it turns out the problem is your old SEO agency rather than a competitor, our guide on cleaning up after a bad agency covers that scenario.

But if you've done that homework and you're still looking at hundreds of spam links that appeared from nowhere — yes, take it seriously. The disavow tool exists for exactly this situation.

The frustrating part is that there's no way to stop someone from building links to your site. You can only clean up after them. Think of it like cleaning graffiti off your shopfront — annoying, but manageable if you catch it early.

Don't wait for the damage

The worst response to a negative SEO attack is doing nothing and hoping Google figures it out. Maybe they will. But maybe they won't, and by the time your rankings have dropped far enough to notice, you've lost months of traffic.

Regular backlink audits are the cheapest insurance you can buy. Catch the spam early, disavow it, and move on. Our free toxic backlink checker gives you a quick snapshot of your backlink health — if you spot a sudden spike in spam, you'll know to act. The site owners who get hurt are the ones who don't check their backlinks until something has already gone wrong.
