Backlinks from PR sites not showing in Open Site Explorer

[pugh]

Hi,

Over the last year I have used a range of different PR sites to post news articles that link back to various pages on my site. However, barely any show up as link backs on Open Site Explorer, neither follow nor nofollow links.

Can anyone explain why this is and whether or not the dofollow links count towards SEO if they are not picked up by OSE?

When did you sign up for SEOmoz Pro? It can take a while for the crawler to acknowledge links. This is from a past Q&A by Joshua Mullins:

"the seomoz crawler is very conservative and will take a while to pick up on links. This has both good and bad aspects. Don't worry though you can always check in Google's webmaster tools for backlinks to your site.

It usually takes 1-2 months for the mozcrawler to find links to my sites. If you are impatient you can try pinging the links with something like pingomatic.com although i am not sure if the mozcrawler listens to those signals or not...."

And a similar reply from Casey Henry:

"OSE is updated monthly with the freshest data that it crawled from the month before.  There are a few different things you need to remember when looking at links in OSE.  First, It may take up to two months before you link will appear depending on when it was crawled and when the system processes it.  Second, the web is very very large and sometimes the spiders don't get to every website and collect every link you've earned.  I suggest you not worry too intensely that the link doesn't appear in OSE but continue to work on getting a wide variety of links.  It is highly likely that Google has found this link and we are still working on it."

Thanks for the reply, sorry it's taken me a while to respond.

I've used a variety of PR sites for the best part of a year now so it seems strange that barely any of them are being picked up.
