Research selling prices of items similar to yours. Look up completed sales or current listings of items similar to yours. Find the high- and low-end prices, and price your object around the median price level. If you want your item to sell quickly, price it at the low end. The condition of the item also affects the price. Items in poorer condition should be priced at the lower end. Also, consider how many listings there already are of items similar to yours. If many similar items will be competing with yours, you may have to set the price lower to get the sale.
If you try to sell a product that is in low demand then chances are that you are not going to get many sales no matter how hard you try. So it is a good idea to spend a bit of time researching and finding out if a product that you are thinking of promoting is a product that your audience needs. If your site gets decent traffic then you can conduct an online survey and easily get input from your visitors.
If you’re planning on relying on SEO for traffic which most people do, it’s all about finding keywords where people would be interested in purchasing an affiliate product, and analyzing the competition of each of those keywords. Back when I was promoting Genesis themes, I saw hardly any articles about “Genesis eCommerce themes” (when I Googled it) which was a popular keyword. I got myself #1 for it. For SiteGround and StackPath, I saw opportunities to write articles on “settings” for each cache plugin (W3 Total Cache Settings, WP Fastest Cache Settings, WP Super Cache Settings, etc). After researching these keywords I was confident I could write better tutorials that the ones out there.
Your domain is the address for your website (e.g., www.affilorama.com) so this is the first thing you will need to do when setting up your site. Considering there are millions of websites on the internet, it's possible that the domain name you want may already be taken by someone else. So make sure you have several options in mind. Be sure to read our advice on how to choose a good domain name.
