Through experimenting, I think I have figured out something interesting
about Google's nofollow tag. The old way to discourage comment spam, before
nofollow, was to use a 302 redirect via a redirect script. But I believe that with Google's
recent algorithm updates in the last few weeks, that they are now treating
a 302 redirect the same as a direct link (without a redirect), at least
when calculating pagerank.
The reason I think this is because I had a bunch of external links coded
with 302 redirects, to
competitor sites and other sites that link back to me. But suddenly , with
the new algorithm update, the competitors jumped way above me in the
rankings, and my rankings sharply dropped (because of the newly detected
cycles in the linking structure).
Have you observed the same thing?

Yes, those webmasters using the 302 rederict
are stealing your traffic :O(

Thanks for the link. On that web page, a reader left a comment, "I think google will soon remove such handling of 302 redirects. That's just a big mistake. Or at least they could make outternal domains to be treated not as the part of your site."
This is in fact what I think Google has done at the same time they implemented rel=nofollow. I believe that a page "A" that links to a URL "B", that contains a 302 redirect to a page "C", can now be considered identical to the case where page "A" links directly to URL "C".
The only reason that Google couldn't implement this earlier was because 302 redirects had a legitimate use in Blogs to defend against comment spam. But now that nofollow is here, it makes sense that 302 redirects should be treated equivalently as direct links. |
Bobby, you can enter that question exactly like that into Google, and you'll get a definition... |
