Please tell me about what are the Do Follow Backlinks and No Follow Backlinks and how to effect them to traffic?
rel="nofollow" is a html attribute used in anchor tags. If these tags are present in your links, then those links are called nofollow backlinks(these links are not counted my search engine spiders, but still few people say they are taken into account. I don't think so). if this attribute is not there in the anchor tags of your links, then it makes a dofollow backlinks (usually taken into account my search engines, backlinks counters, and Page ranks). More the backlinks is more reputation according to search engine spiders and advertisers looking for sites to advertise. You can learn more about these links here
What geeks4share said is correct but just to be clear, there are a lot of opinions on whether no-follow links hold any authority or power, now I don't know for sure myself, I'm not the one to decide that but I believe that every link can be beneficial in some way, as long as it's not spammed or placed somewhere no one will ever notice it. It's hard to say for sure. But anyway yeah as discussed, the main difference is that do-follow links actively contribute to a links power/reputation in Google's Eyes, where as no-follow links don't provide any "link juice"
yea, i agree with you. Every link has some use. No matter if the link is nofollow or dofollow it can bring few traffic
Do follow backlinks are considered by Google but not No Follow, whereas other search engines consider both No Follow and Do Follow.
No-follow backlinks are those backlinks which didn't provide link juice and will not help in increasing PR. while do-follow are those which will give you link juice and will help you in boosting your PR.
If a site has No Follow links Or is No Follow,its links are not Followed or picked up by Google,whiles Do Follow links or sites do otherwise.
Dofollow and Nofollow backlinks can confuse people. The links all look the same if you are just surfing the web but there is a big difference between them to the Google Search Engine. Google intended the nofollow tag to be a spam-busting device. The basic idea is that adding the nofollow tag to a link simply makes it invisible to search engines. The links do not pass page rank and the search engine spiders do not follow them at all.

A do-follow link is that link which allows link juice to be passed to the site which is being backlinked. In short words, Google counts that link. A no-follow link is that in which no-follow attribute is added and search engines don't count any link. Also, no credit is given to linked site.
