i have got a link the html code is <a href="http://www.financecreditinsurance.blogspot.com/" rel="dofollow">blogs on finance</a> i want to know that is rel="dofollow" means google can follow the link?
Google will follow either way. The weighting they give to the link may change though depending on nofollow/dofollow.
Sounds like this trick is used for spamming. Like for example when commenting on a blog that is initially set as "nofollow" and then "dofollow" as other attribute.. Ex. <a href="http://www.example.com" rel="dofollow" rel="nofollow">link spam</a>
dofollow is not a real tag but it's likely google will index it provided there isn't another rel tag stating nofollow. If there is Google will go with the last directions stated within the code. So in wishbone's case it would treat the link a nofollow. BTW know the difference between nofollow and noindex, a nofollow link still gets indexed. The nofollow is a misnomer in seo, it still has value.
1.There's no such thing as dofollow. 2. nofollow is not an attribute, neither it is a tag. nofollow is an attribute value.
