Thank you Airport...
How google judge 'duplicates page'? I think most of those pages are UNIQUE on my site . I know a Ecommerce site, they have many many affiliates partners and host those pages for these affiliates partners , all these pages are almost same except top of these pages(I mean only company LOGO and main navigate bar different ). I traced the site's pages indexed by google for years, these DUPLIACTE PAGES increased to 1.4 million from 0.4 million only six months. That calls googel algo change? Or google doesn't consider that's duplicates page and my unique pages are duplicates page?
sorry I'm cowboy IT person and would like to listen your opinion .Thanks again!
