This is one of my commercial photo websites where photos may be licensed for products or advertising. What I like about Shutterstock is that the photo upload process is quick, and most importantly, they have a good key word tool. When you upload photos to a stock photo site, you’ll need to think of lots of keywords to help your photo be seen in searches.
It’s difficult to think of everything, but the Shutterstock tool finds similar images to yours, and then you can copy all of the keywords used by similar photos. That’s really helpful.
