Links can be made nofollow via the robots.txt file.
So view that file in your browser on the site where the link is placed i.e.
site.com/robots.txt
If you see something like:
Code:
User-agent: *
Disallow: /habaku
In this case, any URLs starting with habaku will be nofollow
And if you are expecting
PR juice to flow to your site, remember that it is diluted by the total links on the page.
Even nofollow links reduce the
PR juice of a page. This is a fairly recent thing as I recall.
And then there could be an automatic block in place in the search engine algorithm for the flow of
PR from some sites to others.
