Got this valuable tips to find what people are looking for or want to buy on the net
If people search using 1-2 keywords, most probably they are just looking around such as they search for “computer parts”
If they want to buy something, they would more likely to search more specific keywords with 3 or more words like “cheap computer parts” or “discounted computer parts”
Also can use other affiliate or merchant programs to look for high-demand products such as at e-bay, amazon, book stores etc.
