I'm about to begin a DMCA take-down campaign. There are hundreds of infringing pages out there, and about half of my 200 pages or so have been scraped to some extent (in many instances just a paragraph or two, in other instances entire pages or multiple pages spliced together). I'm starting with Google Search, submitting all infringing URLs to Google to have those URLs (or at least the infringing content on them) de-indexed. I fully expect that G will comply with my requests and de-index the infringing pages. Here's what I'm wondering:
Can I expect to see a material improvement in the rankings for my entire site on Google's SERPs as a result? Or should I expect page-specific improvements only? Or will all this make no difference at all? Is it fair to assume that the higher ranked the infringing page, the more likely I'll move up (i.e., if it ranked above mine I'll move up one notch, otherwise I won't)?
I guess what I'm getting at is whether G runs an algorithm that accounts for duplication of a site's content in toto, such that the greater the portion of my content that is duplicated and the more instances of duplication Google has indexed, the lower my site's position in the SERPs. If so, then when the dupes are de-indexed I should see a site-wide improvement in the SERPs -- sort of an acknowledgment that I am now more authoritative because G now knows that I'm the one who actually wrote all this stuff.
Keep in mind that I'm talking here just about requests to G to de-index infringing content, and not about filing DMCA notices with web hosts to actually remove the infringing content. (That will be my next step.)
