Nofollow vs Dofollow is a big confusion among newbie bloggers. For them nofollow backlinks don't have as much importance as compared to dofollow backlinks. This is the reason, they keep looking for the blogs which can give them dofollow backlinks.
But this is also a reality that when you comment on a post which is giving you dofollow backlinks then there might be huge comments already on that post. When Google pass link juice to any blog then they check out-bound links on that post and then according to the number of total comment PR is passed to your link.
Let me give you one simple example –
Suppose any blog have PR 8 on any of its post and you dropped your comment there. If there is total 8 comments on that posts then Google will pass PR 8 / 8 Comments means PR1 to all url who commented there.
And if the situation is PR 8 / 4 Comments then Google will pass PR2 to all urls who commented there.
In simple words Google divide PageRank to all the people who commented on that post. Here I took the example of PR 8 with 8 or 4 comments only, but the real scenario is totally different.
So if 100 people are commenting on any PR 5 post then Google will give you only 5/100 value of that PageRank.
So when next time you comment on any post then count all the comments first and then decide what you should do,
So what is importance of nofollow backlinks?
You might have heard many times that Google keep suggesting content relevancy.
What is Content Relevancy?
This is a concept which Google use to distinguish quality of backlinks. According to Google, you must make backlinks from relevant websites only.
If you have a health blog and you are making backlinks from tech or blogging niche blogs than this is totally wrong. When Google spiders will crawl your link then they will keep content relevancy in their mind, and if the backlinks are not from relevant sites then they are not going to give you more priority in search engine ranking.
So if you are in tech niche then try to make backlinks from tech blogs and if you are in health niche then try to make backlinks from health blogs.
How nofollow helps here?
Here comes the importance of nofollow backlinks which you were thinking is a waste of time, because they don't help in getting pagerank for your blog.
When you are commenting on other blogs then most of the times you will get nofollow backlinks, so sometime you think that I should not comment because this is a nofollow backlink.
But by avoiding this activity you are avoiding link popularity.
Now what is link popularity here?
Link popularity is the term used for explaining mutual link between two objects. Means how two websites are connected with each other with links.
Nofollow backlinks help you to make your link popularity strong by giving you relevant backlinks.
So if you are not making backlinks just because sites are giving you nofollow backlinks then start making backlinks from relevant sites and soon you will see great improvement in your blog.
