Image Alt Tags.
Empty image alt tags are very common SEO boo-boos. Image alt tags describe what your images are to robotic search engines.
If you run an ecommerce website, you definitely want to make sure your alt tags are filled out. A good idea is to make sure that the product brand name and serial number are in the alt tag description.

Now, you don't want to use alt tags for decorative images. That can be seen as an over optimization and be a penalty. Just make sure you have your alt tags filled out for:
- Images of Merchandise
- Your Website Logo
- Photos of Team Members
