Other than keyword density, social signals and website speed, link building is among the most crucial factors that influence SEO. Each bank link that leads from a reputable site to yours can give your site a higher page rank.
However, not all websites that link to your site are desirable. Possibly, you’ve engaged in spammy link-building strategies in the past, and are now attempting to correct this.
Perhaps, some links to your website have strangely appeared on a forum or website you’ve never thought about.
Unfortunately, you may not be able to determine whether a third party site should take your links down. It’s here that the disavow tool comes in handy.
What’s the disavow tool?
The disavow tool is the tool that webmasters can use to ask Google to disregard certain bank links when it comes to determining the page rank of a site.
When to use it
You should use this tool if you realize that a particular website has spammy, artificial links that point to your site.
The Possible harm of using the tool incorrectly
Therefore, do not disavow any links from your website for another reason such as if it’s a low PR. This can potentially harm the ranking of your website in a way you cannot reverse.
Remember Google’s algorithms are so fine-tuned and so, you shouldn’t do anything extreme that might throw them off.
Google’sEric Kuan in a thread onGoogle Webmaster Help puts it clearly that you should use the disavow tool with caution because it can cause potential harm to your website’s performance.
Therefore, if you use the tool to disavow those links that are useful in your ranking, it will affect the performance of your site.
So, do not just blindly, disavow links because you’re afraid. Instead, you should be careful, slow, and patient with those links.
