Is Open Site Explorer ignoring 301 redirects now?
-
I just recently saw a huge decline in the page rank of a specific page on my site. When I investigated a bit further I noticed that the drop in page rank looks like it is due to the fact that most of the links to the page come through 301 re-directs from an old page. I know you just made a change to Open Site Explorer. Did you change the way that you are treating 301 re-directs?
Here is the new page:
http://www.justjen.com/shop/big-sister-tshirts.htm
Here is the old page:
http://www.justjen.com/shop/bigsister-tshirts.htm
Up until the last couple of days, the new page was showing the links from the old page in your cache, but as of today, the new page is only showing the links that go to it, not the links to the old page that is re-directed to it.
If there was a change recently, was this intentional (trying to replicate the search engines better) or is it an oversight or database anomaly?

Hey Lawrence,
The changes made to the PA model do not treat 301 redirects any different - we haven't made any updates to how we handle redirects. However, if you've seen a drop in your links, we probably didn't crawl the pages redirecting to you. This would definitely affect your PA score.
I hope this helps, but let me know if you have more questions! If you want to find out more information on the new PA model, Matt Peters, the engineer who worked on the new model, has a great blog post here:

Thanks,

Open Site Explorer: Facebook Shares, Likes, etc.
I don't fully understand what this means in the report for our site: http://screencast.com/t/aG5jbkYWLA here is our site: www.discountqueens.com & we have thousands of fans & facebook likes and all the time on all our posts. For example yesterday we had 73 likes on this post alone: http://www.discountqueens.com/amazon-ultimate-shrinky-dinks-jewelry-designer-1495/ So here's my questions: Is there an error in the reporting? Are we using a social sharing method that isn't giving us valid credit for these links? What should I consider doing differently & why isn't our likes, shares, tweets & Google+ being calculated into our score?

I can't find any inbound links that I know I have on open site, ahref or majestic. Does anyone know why?
Since the linkscape update before Christmas I have built a couple of links to fairly high quality sites. I can't find them on open site though or the other tools I mentioned. I'm a bit concerned there is an issue with my site. Does anyone have any idea why? I'm stumped. My site: www.emporiumofmanliness.co.uk

BOTW links not recognized by Open Site Explorer
Hi there, I was wondering if I buy a submission to the Best of the Web directory (waiting for the new directory list promised by the seomoz team 🙂 ) but when I get to the category on BOTW website that will fit for my website, I took some links already there and put them on open site explorer to see their value, I had the surprise they are not even recognized... So I am still wondering if it is worth or not... voilà , if anybody knows if this directory still has value...
