no I doubt it. we'd have to know what it was to fix first wouldnt we? it could be so many aspects of the structure or algo changes that we can never know, from inbound links being counted differently to age / trust /brand tweaks its pointless trying to speculate really.
i pointed you to the thread to show you that:
a) you are not alone
b) its more than likely nothing you guys have done
c) its pointless speculating
d) so you know im not making it all up
longtail traffic is mainly affected by inner pagerank and your supplemental index ratio / performance, the more pages are in the main index (and hence can rank) the higher the deep traffic count.
the link sculpting we were discussing previously would likely help in this regard anyway, (unless youre removing important links)
We've done a lot in this space. I'm holding off a bit to see if it make a difference.
We have 500,000 threads and for folks that are not logged in, we've trimmed a lot of links off of that page. So we should get a little more SEO focus?
For "Java" we seem to be hovering around #22, but once in a long while I'll see us jump up to #19.
As for overall traffic, last week we had traffic that was better than the previous four weeks. I had hopes that this week would be better still. Monday was by a hair, but tuesday and wednesday were slightly lower than last week.
If forums are still nose diving and we got a bump, that means we are doing awesome! If, however, all forums got a bump, then that means that our SEO efforts didn't really do anything.
