I have seen many Mega-Sites fall in this last update, while smaller Sites gained PR.
Many Sites have taken advantage of replication technologies and list in directory pages for every City in the US, with a lust for "conquering" every city in the world.... Get Real! The Sites using these proliferation technologies seem to be getting hit pretty hard for duplicity of content this time around.
ie... Doing a search on "Dobbin Texas": Hey we live in a town populated with less than 100 residents. We have 2 country stores, railroads tracks, a greasy spoon cafe, clean air and no terrorist threats and we damn sure don't need a "cherry picking" web design and SEO company out of Chicago playing local.
We don't have Dentists
We don't have Lawyers
We don't have Doctors
Hell, many days we don't even have local news.
Veterinarians might be another story, as long as they are in a 20 mile radius and/or pay house/ranch calls!
Are Sites subscribing to these pseudo directory page proliferation technologies the target now? Aren't these "bad neighborhoods" by the strictest definition? Are these not "Gateway Pages"?
We don't have hotels, resteraunts, etc. here either!
Guess what, they are all turning up "Goose Eggs" now, as in PR0.
Do I hear a cleaning for regional or local searches whisping in the latest "house-cleaning" winds?
700-5000 pages - My "bleep"! Why do you have that many pages? Very Few International Conglomerate Corporations create that many products and/or services.
We have a client that markets to 20 Industries with 110 pages having more top 10 SERPS for 1, 2, 3, 4, and 5, keyword phrases than I can count, many in the 5 and 6 digit highly competitive SERP return numbers.
