My site was hit on august 25/26 update and hasnt recovered yet. When i do a site:site.com i find more pages in google index than ever before but my main pages which are in root folder get listed as url only for eg: site.com/widget.htm and yes no "www" infront...the fuuny things is all the other pages are fine. Just the main pages are listed as url only? Also i used to get 9000 hits by google now its like 100. Can somebody help?
I can't help out with an explanation but i can confirm that i've been seeing the same type of behavior on several sites recently. I can't find any correlation between the sites that is is occuring on..yet.
def sounds like a penalty of some sort, only time google ever displays just url, its either not crawled the page fully yet, or, its a penalty. Seeing its on your index page, that im sure, was once crawled fully, i would be worried something is up. i would assume u have many links in as well, meaning google is at ur index daily. i would check everything over, also try doing a search for very specific sentences that only your index would come up for, see if someone else is trying to cloak your index. i know there was some redirect issues recently surfacing, where people were creating sites, based on other sites.
Yea i thought it might be a dup content filter or something too. What if google blocks any effect to pass through these main pages then all the other pages inside those dir would also not rank anywhere? Its funny but the index page also has a full listing and not just url only. But all the pther main pages are on url.
