A new “multiple domain name penalty" will then hit everyone who owns more than a single domain name, and it will be written off as collateral damage because people should “put all their focus into one site”.
I think as any other Google algos changes, this one would have its own collateral damage share too.
However I don't think Google would only look at number of domains owned by a specific company or individual as the only signal of Multiple Domains Crowding spammers.
I think for example when Google notice several domains which belonging to same company are within top 10 listing of search results for a specific search query, Google would take a close look at the profile of said company.
I might expect the profile of a company practicing Multiple Domains Crowding spam to include something like:
- company owns a main domain.
- Company might owns several other domains of just slightly different content than content of the main domain.
- Company might owns several mini sites containing only few pages of similar or very thin content linking back to the company main domain.
- Company might owns one or several "thin" blogs linking back to the main domain.
- Company might be leasing one or several sites to display the company ads which link back to the company main domain.
I don't think the profile of a White Hat company which owns several domains would look like above ;-)
