Optimizing images on website. Is it bad to use the same alt names and keywords?

[artscube.biz]

I have a webpage that I have 6 separate images showing step by step instructions of how to use our product with a sentence describing instruction inside image. I took screenshots of the instructions from the products App and uploaded them to webpage because they provide a great visual. I want to make sure I optimize correctly, can I use the same keywords for all the image names?

thats what I prefer to do - describe the image with the alt tag.
When you can use the target Keyword (in step by step instruction you surely could find ways) do it, but describe the image first.

You need to consider why practically we use alt text to start with.  Alt text assists  visually impaired as they tend to use screen readers in order to browse web pages. Repeating the same information is superfluous not engaging and not helpful to the visually impaired.

Alt text is also how Search engines read pictures. Image search is becoming increasingly important, so repeating the same phrase would not be overly helpful for google to know what to show to answer a searchers inquiry. In fact it could be considered a negative at some levels.

Your alt text should give context and information to each image displayed.  If your image fails to load one day... the alt text is what will be displayed in lieu.

In short each photo should have a context and hence there own description.

Hope that assists.

Hi there.

You surely can, but it wouldn't be called optimization then It's like if you ask if you can have the same text on all pages.

Usually, image optimization includes unique descriptive alt and title tags, as well as file name. Size optimization is probably the most important part, especially on mobiles.

There are lots of guides on the internet about image optimization, but they all go back to UX and looking good + what i said above.
