Here are three methods you can use to detect spam links (that you did not build) pointing to your site.
Method 1: Find spam links in real-time
The simplest way to detect an active link spam attack is to monitor new backlinks pointing to your site.
You can do that by setting up a Backlinks alert in Ahrefs’ Alerts.
Alerts > Backlinks > New alert > Enter domain > New backlinks > Set email interval > Add
You’ll get a regular email notifying you of all new links Ahrefs has discovered pointing to your site.
The image above shows a standard daily distribution of new referring domains to ahrefs.com. Links from 0-30 DR domains will always be more prevalent. Some of them are spammy. It’s normal and nothing to worry about.
After setting up the alert and looking at the history of new referring domains, you should have an idea about your daily backlink portfolio influx. If you see an abnormally high number of new referring domains, it’s almost certainly a negative SEO attack.
Dividing the workload like this whatsapp number list allows both the vendor and the affiliate to focus on their strengths. The improvements are similar on desktop and mobile. Most of the focus in 2021 was on mobile results.
Method 2: Check the referring domains and pages graphs
Use the referring domains and pages graphs in Ahrefs’ Site Explorer to quickly identify spikes in your backlink profile.
Site Explorer > Enter domain > Overview
Now, it’s important to note that a sudden increase in referring domains could be a good thing. For example, one of your posts may have gone viral, or you could have had success with an outreach campaign.
But it could also be a sign of a negative SEO attack.
Here’s how to investigate further using Ahrefs Site Explorer:
Click the Backlinks report
Change the mode to “One link per domain”
Click the Dofollow filter
Click the New backlinks filter
Select the period when the spike occurred
Sort the results by ascending Domain traffic
