After a server crash a couple of years back I decided not to keep all my eggs in 1 basket and split my site onto 3 different servers so for example I have
mysite1.com - 1st database with forums etc
mysite2.com - 2nd database
mysite3.com - 3rd database
All 3 have the same look and feel and include my organisations name. My concern is that search engines will just see my navigation links as external links etc
Is there a way to show search engines these 3 websites are all in affect the same site?
