difference between nofollow and dofollow
If we talk about link building then the first question comes in mind is does nofollow or dofollow links are same?both will help me in indexing? Yes it is true most of the people who are new to seo they are not aware of nofollow and dofollow links atribute, some people says that nofollow and dofollow links both are important but some says that only doffollow links are helpful for your site success, now first we should try to know what is dofollow and noffollow links and how they can effect our ranking.
Dofollow links pass the link juice to the site and it tells the search engine spider to crawl this link and like that your site get link from this site,in other words it helps you in ranking.
Nofollow links do not pass the link juice to the site it have the opposite atribute from dofollow links and it tells the spider to do not crwal this link like that you cant get any benefits from this link.
Now the point is which type of links we should make for our site? there are many people who says that you should make both type and some says only dofollow links you need to make, but if you make only dofollow links it can be suspicious in search engine eye,
If you ask me i will recommend you to make dofollow and nofollow links because like that your seo thechniques will not look like black hat seo.Dofollow links helps you in getting search engine top position but at the same point you have to make nofollow links like i said before ,because there are many top sites, blogs, forums, which have nofollow atribute but it can genrate traffic to your site like that you can get one benefite through nofollow links also.
