Need some advice please. I am wondering what a website such as domainpromocodes.com likely makes per month and how do they do it. Also curious as to what domain reseller sites usually make per month.
I run a competing site to domainpromocodes/retailmenot.com/etc so I can try to help out a little here.
It is a very tough, saturated market. The commission or markup on a domain name is very small, around 40 cents per domain. You are not likely to make anything as a reseller unless you have a very popular site. Hosting commission is higher, but once again it is a very tough and saturated market. Everyone and their mom has a reseller account and wants to start a hosting company.
As for the HOW: It's the same as any affiliate marketing. You sign up for affiliate programs, publish your unique link, and get people to click it. It's a lot of work keeping up with coupons, a lot of work building up traffic, and lots of people simply copy your coupon code and don't use your link... meaning you don't get commission. If you fall behind on adding coupons, people will go elsewhere. Black Friday and Cyber Monday are very busy times for me and I'll be working around the clock those days, but typically I spend about an hour a day updating coupons and stuff.
If it's a market you'd like to get into, I might possibly have 2 domains for sale with matching logos already created. AllHostingCoupons and AllDomainCoupons dot com. Great domains, but they won't be cheap. The script I use is largely custom and I'm not willing to discuss specifics about it, but CouponPress is a decent script to use.
People making money on websites are not likely to tell their competition or potential competition how to compete with them. I debated about even replying to this but I happen to be feeling generous today with the holidays
