Does anyone happen to have an experience with linking two interrelated websites together on the menu bar (primarily for the traffic)? Large authority sites do practice this; Thekitchn and apartment therapy being one that I can think of off the top of my head. This is NOT technically against Google guidelines and Matt Cutts has even said its ok to do within certain parameters. However, what Matt says and what a manual reviewer (probably working under a quota) listens to/does are two different things. This is for two white hat sites (tinged with shades of grey). I wish I could combine the database (wordpress) as well so users would only have to log one time if they wished to post on either site but gave up on that idea - too many technical and security concerns. I do wish to keep the two sites separate both for branding and subject market - both cover related but different very large niches/markets that are separate enough to have their own domains but close enough to be linked together both in content, menu bar, and bottom/side bar related articles. Both are targeted for authority sites status over the course of the next few years unless I do something to get them penalized/banned.
