By which system I identify one blog is dofollow or nofollow.
Find a link in the page that you’re checking on.
Look at the source code.
Do a Ctrl+F and find the link text you’re looking for.
If it says rel=“nofollow” in the link tag than it’s ‘nofollow’. If it doesn’t then it isn’t.
PS - we’ve had that question asked and answered before. You’d be amazed how many questions have been asked and answered before. Another time, please do a quick search or have a look through the forums to see if the answer is already there, we don’t need to keep answering the same questions over and over again!
You can intall a toolbar which allows you to see all nofollow links
Quirk searchstatus is the one I use
There are also other FF plugins that you can use to check whether the link is nofollow or dofollow, if you’re using FF, just search for the nofollow plugin then you’ll find lots of them…
