I want to be sure that all possible ways that google can link my multiple accounts is stopped. I am going to start an SEO campaign with backlinks from Google properties - like Knol, profile pages, etc. I have removed the google toolbar, and ensure that the googleupdate.exe and similar processes have been stopped and all programs that initiate them have been removed. However, I still have many SEO plugins for FF that use google data to check pagerank, ranking positons for domains/keywords, etc. Do I need to remove any and all add-ons/toolbars that tell me google data? It stands to reason that the only way that data can be had is by querying google itself. I will want to eventually make my Google properties (and thus the backlinks on them) look more legit over time by visiting them from other google accounts and making comments, posting links, etc - you know, the type of interaction that looks natural and makes a property look worth indexing, ranking, and giving linkjuice to the sites they link to (money sites I own).
