I've been seeing a steady rise in hits since I changed my domain (from
http://www.devlsoft.co.uk/ to
http://www.wizardslair.co.uk/)
My top 5 sources since the change (these are fairly accurate pre-change as well):
1) Direct traffic [63 hits]
I talk about stuff and link to things on my site via IRC a lot.
2) Google Searches [55 hits]
People using Google. I generally don't count this much, as I don't consider myself to have hit the stage in which people would actively google me.
3) TIGSource [9 hits]
People click on the link in my signature, simple as.
4) Twitter [5 hits]
I occasionally tweet about my site, or people click the link in my profile.
5) Retro Remakes [4 hits]
I get a few clicks from here because I did a remake of an old game back in 2006-7.
I get clicks from Facebook and a couple other forums as well.
I'm by no means a "huge" indie developer, but I still get a bit of traffic.
