Hi In my opinion Dofollow submission is the best for our website because backlink provide do-follow link and no-follow link not provide a backlink but you target your keyword so our keyword ranking increase in search engine.
Dofollow links are basically links that are crawled by bots or crawlers. They usually turn into backlinks but there are many factors that come in picture like for eg: the relevancy of the content, the age of the site and many more. It helps improve the pagerank of the site and more the no of backlinks to your site the better is your site ranking. Whereas no follow links are not crawled and followed by bots. They don't help to improve the pagerank but people normally use nofollow blogs and forums to improve the keyword ranking in the search engine results and drive traffic to their respective sites.
Link through which search engine crawler reaches at your link are dofollow links, while nofollow links don't allow crawlers to access your link. But traffic point of view nofollow links are also beneficial.
Do follow increase your page rank and no follow not increase your page rank so use always do follow websites
Any Search Engine works as per the algorithm and most of the algorithm can't track the no follow links. To create or increase the back links then there is required to get only the do follow links as per the anchor text. Do follow and No follow both links are generate the traffic but Search engine never consider No Follow links as back link.
Do follow link is usefull for link building to the site. and No follow links are also good for Serps.
Please clarify once more. Nofollow links are also count. When you will analyse the total number of backlinks.It will count both nofollow and dofollow. There is a still confusion in the seo people.The best example- Digital point is now nofollow and your signature will be shown in Alexa. Other example, visit the any backlinks website and count the backlinks.
Both do-follow and no follow backlinks can increase your ranking and traffic. The do-follow backlinks are efficient for bringing direct traffic or for increasing your search engine rankings indirectly( other people see the nofollow backlink and decide to link themselves to your website). The Dofollow backlinks can definitely increase your rankings, if you aim to rank high in the search engines you should look for ways to increase especially the number of dofollow backlinks to your website.
Dofollow links are those that gives you link back, while nofollow does not links back. Dofollow is effective than nofollow.
