Our policy
When Knol launched, we began with all pages marked with a blanket "nofollow" directive. This means that Google and other search engines would not crawl outbound links from knols, and those links would not flow PageRank to the pages to which they point. The advice Google provides webmasters is to make links "nofollow" if they represent untrusted or low quality user contributed content.
We are now at a point where we "trust" a certain fraction of authors and a certain proportion of user contributed links, and so we now use a "follow" directive for links within such knols.
Not all links are "follow". Some links will permanently remain rel="nofollow", including:
- Links found within comments
- Our automatically generated links to "similar content on the web".
- Brand new pages and recently-added authors are liable to remain "nofollow" for a period of time.
Beyond that, the rules determining which links and pages use "follow" vs "nofollow" will change over time as we adjust our policies to find the right balance for users and search engines
Example
For those of you who are technically inclined, here is an example. Visit this high quality sample knol on Backpacking, and select "View Source" in your browser. Search for where "follow" and "nofollow" appears on the page. You should see that the page itself gets a global "follow" directive, but certain individual links get rel="nofollow" directives.
FAQs
Q: Are there steps I can take to help my chances of getting into the "follow" club? Is the decision based on volume of non-spammy Knols? I realize there will not likely be a magic formula, but some guidance would be appreciated.
- Follow our Content Policy
- Follow our Best Practices
- Beware of performing behavior that is "spammy". Produce knols that serve the public and not a narrow commercial interest. Avoid bulk uploading of non-unique content.
- Be patient, as our signals do fluctuate over time, and it may take a while for a new user to accrue some trustworthiness.
- If you know that you satisfy all of the above, you can contact us at knolhelp@google.com and report it as a possible bug.

Again, problems with nofollow
I am afraid the follow and nofollow policy affects to my pageviews, currently my knols are nofollow and I don't know why.
I think these changes (or other ones I didn't realize) affects also to the position in google searches, now negatively.
Something related, I cannot check the pagerank of my knols but these one has 6, and other Spanish authors have the "follow" policy with a pagerank of 1.
More things related, the policy for creating metatags from the first words of the summary of each knol is going to be here to stay?
Thanks!!!

Currently meta tags are from the first words of the knols. We cannot comment on whether it would change. You may want to read more at http://knol.google.c

I hope it is a bug. Thanks!

I'm really glad you brought this to our attention. After closer inspection, we did find a critical flaw in the algorithm that determines the "follow'ability" of any particular knol and author. We hope to have the fix to this problem deployed in the next few days. I'll update this thread once it's live and you can verify that the knols of concern are correctly being "followed".

I'm really glad I got your attention! I have checked there were some features which had problems in Spanish interface but not in the English one (recently the references feature in the editor), if you wish you can tell me by e-mail or a comment new features when updating. (I know I should check Knol Announcements and Release Notes, but it is sometimes hard to remember periodically) I can also show new features on the Groups.
Another important issue is about the metatags. Previously there were a cell where we could entry keywords. These keywords remain currently on the metatags of the old knols while after the "keywords cell" dissapeared, the metatags are taken from the summary. The "categories feature" as a "social organization" is great, but so far it is more important the information for search engine Google, isn't it?
Changing SEO policies about Knol is a hidden damage on its position in Google searches. It is one of the most important criticism on Knol. I think the policy must be clear for authors and they should be able to choose (if they want) metatags, but it is quite different to a summary.
Thank you very much for your quick answer and your hard work!

Then, the applied metatags for
meta name="description" content=
Will be the summary as it is being done?
And what about keywords?
Thank you a lot!
Maybe I am excessively worrying about metatags, I am not a SEO expert but anything that could improve the traffic for Knol is a necessary added value to Knol as it is going, that's what I think.

nofollow?
If you see examples of knol pages of exemplary quality which fail to use "follow" View Source, let us know! Conversely if you see examples of obviously low quality / spammy knols which fail to use "nofollow", please tell us.

What is the big deal?
In general I appreciate Google has made Knol as a "do follow" This will encourage more content(hopefully good ones) to be input on on Knol..

We want to make an appropriate and thoughtful choice between "follow" vs "nofollow".
If you look back on our home page, we give this definition "A knol is an authoritative article about a specific topic."
We indeed do want to reward any content that resembles that definition. But we certainly do not want to reward just any content.

I removed the index/follow tag from my web site over the last year or so.... while I still use individual nofollow tags on some of the links I'm unsure of.
In cases where we don't want to indicate the "no" states we could drop those tags and save some bytes.

What does THIS actually mean?
Who is this proverbial "we"? Which authors are you granting this status? And by what criteria is the entry measured?
Sorry, Gregory, if we cannot be more specific about the factors involved. But -- do feel free to offer suggestions if you think they will benefit the experience of both searchers and authors.
Cheers,
Michael McNally writing as Knol Help (signed this one time since the anonymous "we" bothered you.)
