Do img alt tags have an factors on SEO?
I am currently in the process of working to make a clients site ADA Accessible. I`ve spoken with 2 ADA Compliance professionals who have stated according to their data they don`t believe the `alt text` has any actual affect on SEO. However, an Wordpress SEO presentation I attended told me that it does have affect SEO.
What is the general consensus when it comes to images? Is there a hierarchy of importance (Ex: File name > Title > Alt Text > Description, etc).
I bring up the ADA because we find ourselves needed to add descriptions in the alt text that don`t necessarily hit any keywords that particular page is looking to grow in rank.
