Hello, I am a newer in SEO filed . so, Please tell me what is the NoFollow Link and why we use it in sites.
hi, To avoid spamming we use nofollow, but nowadays Search engines pick some of the quality links from nofollow also.
In a simple way no follow links are crawl by search engine spider and also you can get no follow back links. But they don’t share PR juice. So you can't get any advantage in page rank. One advantage of that like if you have a page inquiry.php in your site and there is no need to upgrade that page so at that time you can give no follow relation with the help of robots.txt file. Through that you can save your PR juice.
No follow :- is a value that can be assigned to the rel attribute of an HTML a element to instruct some search engines that a hyperlink should not influence the link target's ranking in the search engine's index. It is intended to reduce the effectiveness of certain types of search engine spam, thereby improving the quality of search engine results and preventing spamdexing from occurring.
