Many individuals don't have the foggiest idea about the real distinction between rel="nofollow" and rel="dofollow" links.
A typical hyper link in which Google and other web search engine bots follows through the link is do follow link. I know this is too short to get it.
Here is an illustration – To rank in Google for a specific keyword you require a few points and the points are number of backlinks indicating your site (inbound links) and Google considers just the link that can be taken after and that is do follow links. More do follow links indicating your site means more the points and more the points that means you rank well.
It isn't so much that all do follow links gets you points. Google has a few elements when positioning a site and one that it considers to give more indicates a site is by PR (Page Rank). A do follow link indicating your site from a high power site (ex: getting a link from BBC)
Example of Do-Follow Link
<a href=”http://www.crunchdigital.in/”>Crunch Digital</a>
It is not required to put rel="dofollow" link because by default hyperlinks are dofollow.
No-follow links attributes don't permit internet searcher bots to take after link.That implies if the site proprietor is linking back to you with no-follow properties, it doesn't go on link juice. Just Humans will have the capacity to take links. In spite of the fact that sooner or later back Google made it clear that they don't consider no-follow link characteristics yet weightage of such links are truly less. Despite the fact that, its a decent practice to utilize No-follow link credit to those link, where you would prefer not to pass link juice. In Short, a link that doesn't permits web crawlers bots to complete are no follow links. A no follow link is included with rel="nofollow" trait.
Example of No-Follow Link
<a href=”http://www.crunchdigital.in/” rel=”nofollow” >Crunch Digital</a>
As indicated by Google webmaster, both the links are useful for SEO yet as contrast with nofollow, dofollow link has more significance.
