It seems like (all?) of the discount/coupon websites are focused on things that you can physically buy. Do you know about any where I could promote my web hosting service?
Google for something like "coupons for webhosting services". On the website retailmenot.com, for example, there are such coupons and promo codes. Seek, and ye shall find.
You can submit your web hosting site to web hosting directories. You can also use Bing ads or Google Adwords top get initial boost to your web hosting campaign.
I agree with "avpol"... seek and you shall find. Just think about how you want people to find your deals and go where they would go.
yes I too have a coupon website with a enough traffic on it if you want to advertise coupon on my website you can too check out for sample too hostgator black friday more such type of coupons on web hosting you can share with us
If you can't find a site (or there are scarce sites) for you to promote your website on, then that sounds like a great niche where you can build your own site a promote it with little competition. Things that make you go hmmm.
