Backlink diversity is an important ranking factor in search engine optimization (SEO). One important factor to consider is the Class C IP range of the domains linking to your site. Google and other search engines reward backlinks to a diverse range of unique Class C IPs, as they are highly likely the result of organic link-building, and not the product of a manipulative link farm.
Even here, the Class C IP Checker makes an important component of the SEO tool. In this post, we’re going to clarify what a Class C IP Checker is, why it’s important to your SEO strategy, and how to use one efficiently.
Understanding IP Classes
As we know every website is hosted on a server which has a unique IP address. IP addresses are divided into four sections (octets), such as 192.168.1.1.
When search engines see that all of your backlinks come from websites hosted on similar Class C IP addresses, they might interpret your backlink profile as unnatural — a sign of either link farming or manipulative link building. Conversely, you can mislead Google with backlinks from other Class C IPs indicating a natural and diverse link profile you will increase your SEO performance.
A Class C IP Checker analyzes the IP addresses of all your backlinks and shows you how many unique Class C IP ranges they come from. This allows you to assess the variety and quality of your backlink profile.
Link diversity is a powerful quality signal in the SEO world. Having all your backlinks from the same network and coming from the same hosting provider can be slightly suspicious even. Internet search engines like Google may consider this to be a link farm or a link building scheme, which is bad for your rankings.
181 unique referring Class C IPs — on the one hand, links from a large number of different Class C IPs indicate that your site is receiving links from many different independent sites, adding trust and credibility.
A Class C IP Checker is usually very easy to use:
1.Enter your website URL: The tool will crawl all the backlinks that are pointed to your domain.
2.Collect IP Data: The referring domain of each backlink is resolved down to the IP address.

Here are some best practices to maintain a natural backlink profile:
1.Target Diverse Websites
For backlinking, link to any webpages hosted on unique providers and networks. Try never to get links ever again from the sites served on the same shared hosting IP blocks.
2.Emphasize Quality Instead of Quantity
Instead of chasing hundreds of blog network backlinks, you should get genuine links (with dedicated hosting and different Class C IPs) from companies of your industry.
3.Regular Backlink Audits
Here is the catch: This process can take time, and you don't want to wait until a Google penalty hits. Regularly monitor your backlink profile using tools such as a Class C IP Checker and correct potential issues in their infancy.
4.Stay away from Private Blog Networks (PBNs)
