There are nofollow and dofollow in SEO. I have read some blog that they says dofollow link brings better ranking. Is it right ? Then why will I use nofollow link?
Why will I use nofollow links, because look like a natural. If we all are submit only dofollow links then google thing I am only marketing our website or blog. Some time nofollow links is helpful for getting good traffic. For Example: Squidoo.com is provide nofollow links. So, i will not post my content squidoo site. No I will publish because Squidoo.com is high pr site and help of this site I will getting good no. of traffic.
Just get a plugin off firefox that displays all types of link commands and you'll see which links to use and will bring you rank.
To me do-follow or no-follow doesn't matter until and unless they provide me conversions. if a do-follow link provide me link juice and a no-follow link provide me conversions, I will opt for no-follow one. I don't think link building like this works any more, yes natural links whether no-follow or do-follow are still my choice. Since you asked opinion at board, my opinion is: The focus of a good link builder should be to get links from quality sites where client get conversions or sale. ROI matters a lot.
You should have to make a balance in between the use of both dofollow and nofollow links..Both are beneficial for a site in bringing a relevant traffic..
