I own four sites. Two are similar topics. I've just watched a Youtube clip of Matt Cutts explaining if you should cross link sites.
Now I know I'm not supposed to mention my own type of site here, so I am going to make up two examples (my sites aren't about jogging, riding, cooking or roof repairs).
Site 1 is about jogging
Site 2 is about bike riding
So, both are about exercise, but riding and jogging are different. Some people do both. Would you cross link those sites? I understand linking a site about cooking to a site about roof repairs might be a bit weird.
