Although they may be getting around dupe filters, I think that ultimately their page perfect SEO will be their downfall.

I suspect that Google is quite adept at differentiating the ‘average Joe’ website from the highly optimized site by closely reviewing on-page attributes. I also suspect that Google is penalizing already (albeit ever so slightly) pages that are in fact, overly optimized.

I suspect this because many of us have reported that our unkempt sites are tending toward higher PR and SERP position while those sites that receive our greatest efforts tend to stay the same, or may even fall.

If this is true, the site you reference that is so good it gets around dupe filters, will ultimately fall because of its SEO perfection.

Think about it. . . Google created this monster with reliance on links. Now, linking is totally out of control. So if Google de-emphasis links, where can it go. . . back to on-page stuff.

The issue is simple in my simple mind. SEs can evaluate only two primary data sets, on-page and off. So, if Google tweaks down off-page importance, it will probably increase on-page importance. If so, Google must then work harder to cull pages that are built specifically for ranking (highly optimized) and must diminish visibility on those pages.

That’s my speculation on where this is going. If I’m right, the SEO experts may start getting paid to undo the work they did yesterday.
