when we comment on blogs either dofollow helpful for us or nofollow or both in making keywords positioning higher in google.also provide the authentic links if possible.thanks in advance.
get back links by commenting on a high authority blog only.Do real commenting after reading the whole blog post carefully.
You need a combination of dofollow and nofollow backlinks, otherwise you create an unnatural backlink profile.
Do-follow are more useful then no-follow but it doesn't mean that you only commenting do-follow. Also prefer no-follow for natural linking.
This. Those that focus entirely on dofollow backlinks are always going to run into difficulties. Finding the balance between the two is key. WebDev
First of all understand work of do follow and no follow back link. Do follow back link very help for crawler to go one link to another link, with the help of do follow back link visitor and crawler both will be reach your linking location.. But through no follow back link only visitor can reach on your linking location not crawler. so do follow back link is very beneficial for your website instead of no follow back links..
do follow help us but no follow links are also not worthless.... no follow is also beneficial but not more than do follow...
According to Matt Cutts, only Do-Follow helps! but practically people have noticed that nofollow links also helps, for example, link from Wikipedia also helps although its no-follow!
When using comments on blogs . No need to for any do follow/ no follow. But for directory and book marks do follow makes more value than no follow.
Regularly comment on your niche specific topics without caring about the dofollow or nofollow. This way you end up with a mixed combination of both type of links.
Do follow can help a lot.I cant say about no follow ,as per my knowledge try to choose do follow links.
