Most advice about SEO focuses on what you can do to improve your own rankings, but there’s a darker corner of the industry that works in the opposite direction. Blackhat SEO, in this context, doesn’t just mean shady tactics people use to boost their own sites, it also refers to attacks aimed at damaging a competitor’s rankings instead. These attacks, sometimes called negative SEO, have become common enough that any website owner with a reasonably successful site should know what they look like and how to respond.
What These Attacks Actually Look Like
Negative SEO takes a handful of recognizable forms, and understanding them makes it much easier to spot when something’s wrong rather than assuming a sudden ranking drop is just an algorithm update.
The most common tactic involves building large volumes of low-quality, spammy backlinks pointing to a target site, often from link farms, foreign gambling sites, or adult content domains that have nothing to do with the target’s actual industry. Search engines have gotten better at recognizing and ignoring these links on their own, but a sudden flood of thousands of irrelevant backlinks can still occasionally trigger algorithmic suspicion or manual review.
Content scraping is another approach, where an attacker copies a site’s content and republishes it elsewhere, sometimes even managing to outrank the original in search results if the scraped version gets indexed first or ends up on a domain with stronger existing authority. Some attackers go further, creating near-duplicate versions of a target’s pages specifically to confuse search engines about which version is the legitimate source.
Fake reviews and reputation attacks fall into this category too, particularly for local businesses. A wave of coordinated negative reviews, sometimes from clearly fake accounts, can hurt both a business’s local search rankings and its actual reputation with potential customers browsing those reviews before making a decision.
Spotting the Signs Early
The earlier a negative SEO attack is caught, the easier it is to limit the damage. Regularly checking your backlink profile through tools like Google Search Console or third-party services such as Ahrefs or Semrush makes it much easier to notice an unusual spike in low-quality links pointing to your domain. A sudden, unexplained ranking drop across multiple pages, especially one that doesn’t line up with a known algorithm update, is also worth investigating rather than dismissing.
Running your own content through a plagiarism checker occasionally can reveal whether it’s being scraped and republished elsewhere, and setting up alerts for your brand name or key phrases from your content can help catch unauthorized copies faster than stumbling across them by accident months later.
Protecting Your Site Before an Attack Happens
A certain amount of protection comes simply from having a technically solid, well-maintained website. Search engines are generally good at recognizing when spammy backlinks aren’t the site owner’s fault, particularly if the rest of the site’s link profile looks healthy and natural. Keeping your own backlink profile clean, avoiding shady link-building schemes yourself, and maintaining consistent, original content all make your site more resilient if someone does try to target it.
It’s also worth setting up Google Search Console if you haven’t already, since it provides direct visibility into how Google sees your site, including manual actions, security issues, and backlink data that would otherwise be much harder to track down.
Responding If You’ve Been Targeted
If you identify a wave of spammy backlinks pointing to your site, Google’s Disavow Tool allows you to formally tell Google to ignore specific links or domains when evaluating your site. This tool should be used carefully, since disavowing legitimate links by mistake can do more harm than good, but it remains the standard response to a confirmed negative link attack.
For content scraping, filing a DMCA takedown request with Google, or directly with the hosting provider of the offending site, is usually the most effective route. These requests can be time-consuming, but they’re generally taken seriously and can result in scraped content being removed from search results entirely.
Fake review attacks require a different approach, usually involving reporting the reviews directly through Google Business Profile or the relevant platform, along with documenting the pattern in case an appeal or escalation becomes necessary. Responding calmly and professionally to any reviews that do stay up, rather than getting into public arguments, also helps limit reputational damage to actual visitors reading them.
Negative SEO attacks are frustrating precisely because they target something you built rather than something you did wrong, and the response usually requires patience rather than a quick fix. Staying on top of your site’s backlink profile and content footprint, and knowing which tools to reach for when something looks off, puts you in a far better position to limit the damage and get back to normal rankings once the issue is resolved.
