Alt tags
These are highly overused or under used. Alt tags are used for the visually impaired for the images on your site. Some people just used to stuff them with keywords, competitor’s names, link other sites and more. The new authority way is to utilize these in the way they should be used. A simple description of what the image on your website is showing. Color, size, even ingredients on a bottle. Alt tags use what they call a screen reader and when someone is partially blind or has different disabilities to use this feature it actually speaks what you type in there. Google seems to reward those now that are using this feature for what it is. Those who stuffed those words and create a higher bounce rate will be shown less.
