I've just been checking backlinks in google webmaster tools, and two of my sites are showing links from google directory. I think google directory just imports it's data from dmoz, and I know both these sites didn't get listed on dmoz until late last year. This is definitely a recent dmoz export.
dmoz.org has a pagerank of "no information" so something is happening. One of my sites just got listed in DMOZ a few days ago and my pagerank went from 4 to 3 so I'm really hoping this is fluctuation.
Even my sites fared well in the number of backlinks indexed by google. It went from a mere 20 to 165. I checked it in the google webmaster tools. That shows that the work for PR update has started
Google updates its Webmaster Tools 'Inbound Links' approx every 3-4 weeks, not before every update. However, they do usually export the 'link:www.yourdomain.com' data just before a PR update. With regards to the Google Directory update, it happened before Christmas. See this post: http://forums.digitalpoint.com/showthread.php?t=616586
Thanks spider-man, I missed that. Been out of the loop for a couple of weeks, perhaps a bit too much Hogmanay partying Sorry for duplicate post.
Inbound links are updated at different intervals depending on how popular your site is, just like how google crawls your homepage depending on how often it changes. If you only have a handful of backlinks, it might only update once every 2 months. Or, it could update every week.
I also noticed that the "link:yourdomain" data changed. What I observed though is that the count went up across the board for my sites and those of my competitors. One of my sites went up 3-fold, and I didn't do an ounce of link-building on it for the past year.
