I have a forum where members post lots of link in their forum, i'm worries that pagerank will be drained to each one of those link So I'm thinking on place a meta tag like <META NAME="ROBOTS" CONTENT="NOFOLLOW"> Code (markup): Will it effect my pagerank (I've heard some people say that Google will award me a pagerank of 0 if I do so, is it true ?) Tell me more about it. Thanks
This will only help to stop google indexing your pages! Remove it immediately. If you are concerned about PR leak / linking to bad neighbours - you will have to add "nofollow" to the links posted by users and optionally to the links in their signatures. Can be done easily in most bulletin board softwares.
But according to http://www.google.com/support/webmasters/bin/answer.py?answer=35303 <META NAME="ROBOTS" CONTENT="NOFOLLOW"> will instruct robots to index the page on your site but instruct them not to follow outgoing links
this tag is something like to stop google knowing about your outbound links in your website. If you already have a PR that will not be effected. Even it will not make any improvement in your PR
The mentioned tag doesn't have to do anything with your pr, however I assume that meta description tag contributes a little bit.
This tag does prevent google from following (Or at least counting) the links on that page, including your own internal links. I agree with the people here who've said that you should automatically ad rel no follow on the links people post - if you are worried about this. If it's a webmasters forum, people will resent that. On any other type forum: I really don't think most people will notice. On DP, where people are specifically looking for SEO advice and help, people really appreciate it that links are not handled with rel no follow. I don't think the PR leak will be that bad though. That sort of thing perhaps mattered when google relied on PR a lot. Right now it really doesn't any more.
Well, yes the meta directive will just disallow the spiders from crawling the content and indexing it. It has no effect on PR. PR will depend entirely on the backlinks pointing towards the page
Yes, it affects PR. Just like not including Google in your prayers and not sending them 10% of your money as a donation.
