I have a large website, twenty thousand pages plus, with half a dozen landing pages that have been optimized for SEO. All of those landing pages had 301's from different URL's that I had set up in the past few years before combining them all into a single webpage. I used a paid link building service for all of the 301ed URL's that point to those six landing pages. Most of the links to the new webpage were built by a paid "professional SEO service" (for whatever that's worth). Most are relevant, might have some spammy looking stuff, but I think typically what you would generally get from a paid service. All of my most important keywords to those six landing pages got hit. I had about 150 keywords/ phrases on page 1 almost all have been scattered from page 2 to 20, and some beyond that. (The same group of keywords that came from the original 6 webpages). The strange thing is; I have all these other pages that still rank in the top 3 positions that had no links to them at all- no SEO at all- just the title of the page (the keyword) in the URL. So my question is this: Is it possible that the Penguin Update didn't demote my entire website, but only the six pages that had the bad links? Or.... Could they have demoted the actual keywords, but not the entire website?
