I typically made between $500 and $1,000 a day every day during Black Friday Week, Cyber Monday and Cyber Week. It is lower during other holidays like Mother’s Day, Father’s Day, Presidents Day, Valentines Day etc. but you can still promote various sales during these holidays as well. I target every holiday because Amazon creates an actual dedicated sales page every time one of these holidays come around. The deals shared on these pages are generally really good too.
Again, if your blog has a large reader base, then businesses may be interested in paying you to review their services or products. Not only will you get a free trial using whatever these businesses are selling, you will also get a fee for writing them a review and posting it to your site. Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.
