The best way to optimize product pages is by using keyword density, optimizing images, and listing the benefits of your products. You can ensure that your content is found by potential buyers when they are searching for information about your products.
The higher the keyword density, the more likely it will be found by Googlebot when someone searches for that term.
Optimizing images can also help improve click-through rates (CTRs), which is how many people who see an image click on it instead of scrolling past it. Too often, images are low quality and need to show off portions of a product adequately. Listing all the benefits associated with each product helps educate consumers about what they're buying before making their purchase.
