Welcome to WebmasterWorld Guest from 220.127.116.11
Has anyone had good results using rel=nofollow to control PR flow?
Have you tried adding:
<meta name="robots" content="none">
<meta name="robots" content="noindex">
to the pages that don't matter? That will remove them from Google's index directly so they don't take up non-supplemental spots.
I'm was using content="noindex" already and adding rel="nofollow" to a lot of links on top of that had the above affect.
I found one of the reader comments on this blog post interesting:
In the context of trying to flow PR to your true content pages in an effort to help to get them out of the supplemental index, and not to waste PR on the way to your real content pages; it was suggested (unlike the “nofollow” link tag mentioned in the posts above) to use the meta: <meta name="Robots" content="follow, noindex"> on ALL pages (category navigation, tag clouds, sitemaps…) with the exception of your index page and your REAL content pages.
Which, as it was suggested (or as I understood it), would accomplish two things:
1) It would still give you the benefit of the onsite navigation PR flow that is followed on the noindex-ed pages, however (as it was suggested) that by not indexing those pages, it would flow more PR to your real content pages.
2) And leave room in the main index for more of your site to get bailed out of the supplemental index.
Has anyone tried this? Results?
A question though. Will PR still flow to a page with noindex? Will googlebot realize that if a page uses noindex that it is basically pointless for PR to flow to it?
Everyone's site is different. I particularly wanted to de-emphasize the Contact Us page to reduce the number of SPAM attacks on my web form in addition to giving my product pages a bit more ranking oomph. Generally speaking, my attitude is that if people want information about me or my site, I'd prefer that they start on my main page where they can easily navigate to the appropriate internal page through prominent links - but only after I've had a chance to give them some ideas for other pages to check out on my site once they've taken care of their first chore.
Will PR still flow to a page with noindex?
Yes. The noindex keeps that url from being shown in search results. But as long as links point to a url, then that url will accumulate PR.
Its outbound links will pass PR along to their target urls, too, unless the meta tag is "noindex,nofollow" or there's a rel="nofollow" in the anchor tag itself. That passing along of PR can be far from pointless, itcan be important for other pages on the site.
Unintentionally shutting down this PR circulation can also be one area where people hurt their own site when they are too casual about using nofollow for internal links.
Let me ask, since the others are also supporting the nofollow attribute, what type of behavior have you seen with Yahoo!, Live, etc.?
It is interesting that you ask about Yahoo. It is generally understood that when you search for back links in Yahoo, that Y lists them in order of “importance” or weight.
My number one back link on Yahoo is from Matt Cutt’s. I posted in his blog with my url. And he is using the no follow tag for blog comments.
So, it would appear, that Yahoo is not recognizing the no follow tag.
