While this isn’t applicable to all niche’s, flash games are a great wait to encourage people to link to you.
The reason why this works so well (in theory) is because not many people know how to view your html source code and jack the .SWF file So they have no other choice other than to link to you.
Just a small little tip that has never failed me.
I’ve hired flash game designs from $100-$200. It isn’t that expensive.
