What are Nofollow links?
No follow links are a low percentage on the web. They prevent sites from getting spammed. They are a way for webmasters to tell search engines not to follow a specific link or links on a page. The meta tag was suggested initially to stop comment spam in blogs, back in 2005.
How does the nofollow meta tag look like?
The attribute appears in the page-level meta-tag:
<meta name="robots" content="nofollow" /> For telling search engines and bots not to follow a specific link, and to instruct robots not to crawl it, you can use:
<a href="signin.php" rel="nofollow">sign in</a>
Why are they important?
The basic idea with nofollow links is that Google does not transfer Juice (Authority) or anchor text across these links. You might want to use the meta tag for untrusted content. If you have doubts about user comments or guestbook entries, you can no-follow the links. This way you’ll discourage spammers and you won’t pass Authority to those who don’t deserve it.
In a similar way, you can use the meta tag to control the content on your site and any time you don’t want your site to be seen as endorsing links.
You could also want to use the meta tag to prevent paid links from influencing search results and negatively impacting users.
Another benefit of nofollow links lies in the crawl prioritization you can make. Whenever you have “register here” or “sign in” links you can add the meta tag. This way you can crawl other pages that would count in your Google’s index.
How to use it
You can simply add it on your own, like this:
<a href=”http://www.example.com//” rel=”nofollow”> link to a page</a>
Many times, it will be automatically added, or you can talk to your webmaster or team to show you how to do it.
What are disavowed links?
You can disavow untrusted links by using Google Webmaster Tools. By doing this, the next time that Google crawls that link an invisible no-follow tag is added to it. Both your disavowed and no-follow links are listed in your Google Webmaster Tools.
How to disavow links?
You can get all the explanations here, of which I’ll make a summary.
- You need to download all the links to your site and put the ones that you want to disavow in a separate file. Upload it to Google.
- The file must be a .txt. type and it must be encoded in UTF-8 or 7-bit ASCII. You should write one link per line.
- If you want to disavow links from an entire domain, use: “domain:example.com”.
- You can add comments and additional information, by using “#” before your comments.
- Go to the disavow links tool page. Select your webpage. Clink on “disavow links” and upload your file by clicking “choose file.”
Now you know what nofollow links are and disavowed ones, and how to use them. Hope you’ve found this helpful!
