There are a lot of questions regarding how Google tracks backlinks. When a website has a number of links coming from the same IP address even with different referring domains, it does not look natural. In fact, it looks very spammy and fabricated. Google figured that out a long time ago. What else is Google looking at?
1. Total Number of Inbound Links
Looking at all of the competitors in this matrix, we can see that some of them have massive amounts of links. This information is completely useless. I’ve seen spammy blog networks hit websites with 100k backlinks and take their traffic down by 30%. What is more important is the referring domains.
2. Referring Domains
When comparing the amount of referring domains to total links, I typically look at the ratio. For instance, dizzyheights.com has 116,714 links coming from 63 referring domains. This means absolutely nothing to Google! If anything, it’s most likely hurting their rankings. It appears spammy and completely fabricated. Going deeper, we step into the referring IPs.
3. Referring IPs
Many websites share IP addresses. When your hosting multiple websites on the same server, in many cases you’re sharing an IP address with the same IP address. You can use a reverse IP domain check
to see other websites you’re sharing an IP with. You not only want your links to be coming from different domains, but different IPs as well, otherwise anyone could manually build backlinks which wouldn’t be good for Google.
4. Referring Subnets
To take it a step further, Google checks to see if your backlinks are all on the same subnet. Even with different IP Addresses, they can still be on the same subnet.
5. Deep Link Ratio
When people naturally link to a website, they usually link to a relevant page. If all of your backlinks are pointed to the root domain, chances are that it’s either a bunch of directories or backlinks are being manually fabricated. The higher the deep link ratio, the better.
