Google and Duplicate Content listing changes

[$5 submissions]

Maybe it is related to stuff similar to http://www.gofuckyourself.com/showthread.php?t=745365 but anyone with a LOT of pages notice that Google is no longer showing "similar" pages as independent listings but HIDING them?

Similar pages will simply hit supplemental results. If these pages are to close it will show the most dominant ranked listing since it can't determine the differences between the pages. Otherwise it's a standard suppl result and needs to more backlinks with proper anchor text.

Two weeks ago google hit a sandbox on some sites, and they started to lose ranking. About a week ago they did some algo change which shifted some rankings but overall didn't seem to change much. And as of late last night some big happened or a relist is taking place.

Either way, I'm waiting a few more days before I start looking for problems.

Thanks, Doc. The reason I ask is because we produce THOUSANDS of pages of original content for clients. I was looking at competing pages and it looks like those pages are getting socked while the original content stuff are still alive. It used to be that competing pages (which used duplicated, scraped, or spun content) would be listed as supplemental but the listing # (total results # not listed entries) would be very high. This seems to have completely changed now. I would not have noticed if I didn't look at the competing stuff. I noticed this last week. This might or might not explain the recent surge in SERPs across differing categories.

This could be a duplicate filter update, very hard to tell at this point. The last major google update made the serps look odd for a couple of days, like they are now, then a few days later they settle back in.
