please share your views about is really no follow and do follow sites shows an effect on sites keyword ranking? Should we check is site do follow or no follow before submitting a site?
Do Follow backlinks give some authority and Link Juice to the targeting site that No-follow does not give. So it is good to have Do follow backlinks but with a mixture of some No-follow to make your site backlinks more natural.
Do follow links also helps in getting Ranking in SERP as well as also helpful to increasing page rank of site due to they provide link juice from that site.
The dofollow for internal linking and inbound links very good for your site, The nofollow link is good for external website(other website) links. The dofollow increase seo ranking and page rank.
Yes, dofollow and nofollow links are helps for increasing website ranking. Dofollow links are better than nofollow links. So, try to working on high pr dofollow sites.
Dofollow links have effect on your rankings, but you should have a specific percentage of nofollow links as well, even though they are useless to your website.
Dofollow are the links you want to help you increase your PR, but I don't avoid nofollow as they might not help with your backlink building, but they certainly help bring in dribbles of traffic to your blog.
I agree with deansaliba, that both of us are important in SEO, but for ranking dofollow are helpful becoz dofollow links are index by search engine, while nofollow links are not index by search engine. But nofollow links is helpful to increase the website traffic.
Do follow and no follow are link attributes and contain instructions for search engine robots. Do follow links are crawled and indexed in search engines whereas no follow links are never crawled and indexed in search engines.
Nofollow links don't allow search engine bots to follow your links. These links don't pass on link juice. Only people can follow these links. They don't help you to boost Page Rank, website rankings and have no SEO value.
