How to check bad backlinks for SEO?

A bad backlink is an inbound link from irrelevant or malicious websites that can hurt your SEO. They make your website look spammy and destroy your reputation with Google and other search engines. 

You need to get rid of these backlinks before Google hits you with a penalty.

In this blog post, we will show you how to identify bad backlinks, what makes them harmful, and how you make them disappear. Here’s the step-by-step process of identifying bad backlinks:

  1. Export the list of all backlinks listed in Google Search Console and Ahrefs
  2. Check if linking domains look shady or qualify as a link farm
  3. Looks for backlinks from forums or blog comments
  4. Identify press release links
  5. Highlight backlinks with over-optimized anchor texts
  6. Keep an eye out for domains that pump multiple backlinks
  7. Looks for these signs of a bad backlink
  8. Filter out spammy backlinks and move into a new spreadsheet

Google Search Console is a free tool that shows how your audience, from Google Search Pages, interacts with your website. It also enlists detected backlinks to your website.

You can find the list by clicking on Links in the Google Search Console Menu, and scrolling down till the Top linking sites list.

Alright, now that you have the list, it’s time to filter out harmful backlinks. 

Does the host website have tons of ads? Blog posts full of affiliate links? If yes, there is a chance that the website is spammy. When you see content stuffed with keywords and every blog pointing back to sales pages, you must get rid of backlinks from that website. 

Quality websites take a content-first approach – they offer value to their readers.

On the other hand, link farm websites boost their domain authority by linking to each other. Effectively, these websites got backlinks because of a business deal, not because they offer value. These low-quality websites are collectively known as Private Blog Networks (PBNs.)

Google knows that these websites offer nothing to readers, so even if you get a backlink from them, Google might ignore it. But with Google pressing down on poor quality bad backlinks, it’s wise to get rid of backlinks from link farms.

3. Looks for backlinks from forums or blog comments

Not every discussion forum backlink is spammy. But, if your backlink profile is full of discussion forum backlinks, you must get rid of them. Instead, focus on creating top-quality content that generates natural backlinks.

Comment links are backlinks from the comments section of a blog post. Before the Google Penguin update, this technique worked wonders. But now, it is an ineffective method of building backlinks.

4. Identify press release links

Press Release backlinks are created by crafting one press release copy and publishing it on many forums. This means the same content is published on multiple websites, backlinks from such sites can get under the black-hat category.

5. Highlight backlinks with over-optimized anchor texts

An anchor text that matches exactly with the blog title is over-optimized. These backlinks may not be harmful, but to make your profile look cleaner, reach out to website owners to edit the anchor text.

6. Keep an eye out for domains that give out multiple backlinks

Some domains may give multiple backlinks – one each from different category pages. Essentially, these domains create many different pages on closely related topics and link to your website. This fills your backlink profile win low-quality bad links that may impact your rankings negatively.

7. Looks for these signs of a bad backlink

1. Backlinks look like they were generated through Fiverr

With Fiverr, you may get poor quality bad links unless you know how to qualify a Fiverr backlinking gig. These backlinks are generated using crappy content and irrelevant websites that add no value to readers or your websites.

If you got any Fiverr backlinks from guest-posting, check if the backlink is worth keeping.

2. Backlinks from foreign language sites

If you see a surge in backlinks from Turkish websites, while you write in English, it is a matter of concern. These backlinks, in bulk, indicate a negative SEO attack on your website.

3. Hidden backlinks

In the early days of SEO, it was common to link agency websites from client websites. Often, these backlinks had anchor text of the same color as the webpage background. This caused backlinks to hide in plain sight. The visitors could not see them, but search engines could.

But this is a black-hat SEO method now. If you have such backlinks, you need to get rid of them fast.

4. Multiple backlinks from unrelated websites

Google prefers relevant backlinks to your website. If you own a dog grooming website, you should get backlinks from other dog grooming websites, or dog behavior websites, or dog park websites.

But if you get tons of backlinks from a Tupperware website, Google may ignore those backlinks or penalize you for them.

5. Paid Backlinks

Paid backlinks are a grey-hat SEO technique. Paid backlinking is a way to cheat the Google algorithm. As of now, Google can’t discern between paid and natural backlinks, as they can’t openly peep into your mailbox.

But the recent link spam update shows that Google is putting more focus on quality backlinks. Once they find a way to identify paid backlinks, a lot of websites are losing rankings.

6. Sitewide Footer or Sidebar Links

Another old method of building backlinks was to add a backlink in the website footer that occurs on multiple webpages. It’s obvious that not all those pages are relevant to the backlink, this makes such backlinks black-hat.

7. Slow loading pages

If the page takes too long to load, has a poor layout, or low quality content, you can assume that the backlink is low quality. A quality website has it’s technical SEO taken care of and loads within 5 seconds. You can confirm the speed using Google pagespeed insights.

Alright, now you know what a spammy backlink looks like. You can individually assess every backlink to your website and determine if it’s spam. But it’s a highly time consuming process, plus it’s difficult to identify every bad backlink, so you may end up removing good backlinks and keeping bad ones!

This can be avoided if you use Semrush. In fact, you can complete the whole backlink audit using Semrush alone! 

Semrush is a powerful tool that can simplify and speed up your backlink audit process. This tool assigns a toxicity score to each backlink to your website, eliminating misjudgment in picking bad backlinks.
