(I hope this is the right section to post) How will someone SEO a coupon site because there is no article writing only press release?
There are many way to SEO a site. On page things you can do are keywords in your urls. Off page things such as backlinks, social bookmarking, Forum posts. Hope this gives you a good place to start.
I agree with Flexin, for offsite at least you should have a fairly standard job of building your backlinks from various places, web directories etc
Ok, so if you have coupons you can obviously provide information related to the product\service the coupon is related to, there is "plenty" of relevant content you can use with this type of website.
