hi, i have 3 sites with the same theme, all of the on the first page. i wonder if i can put crossed side wide links between them to give a little push on the serp? i host them on the same server. thanks
Yes you can cross link them if they are of same them & if you think they will provide value to users. Check this link for more information http://googlewebmastercentral.blogspot.com/2007/08/server-location-cross-linking-and-web.html
Yea you can..but it's not going to give them a push..you will have to do some good old seo to make that work..
