Wow, my head hurts, just out of bed and this topic has exploded. I read a couple more pages. Firstly, i make zero cash from the site, in fact it costs me to run it. I tried putting adds on it before but i was making something like 20 cent per day so took it off again. I also have an add on the homepage of the main site but i dont even have the login or password to check how much i have made on account of it being so low as well. I should really take it off but totally forgot about it. I'll remove it now.
Anyway. I still have the main
www.ps3.ie and
www.ps3-leagues.co.uk domains but the forum is only on .co.uk. I had the 2 domain endings before but then i had two copies of the exact same site on two seperate domains which google classes as duplicate content spam so i had to remove one of the sites. I kept the .co.uk as as a .co.uk domain does a lot better on google.co.uk which is where i get the majority of the hits so it made sense.
Also, the title of your site is very important to google and also appears as the link text when people do a serach so i am just testing to see if i get more people signed up when i add the UK in the title.
Hope this clears it up further.
