ALT attribute keyword on the same image but different pages

[Stuart26]

Hi there,

As i'm sure you're probably aware, moz advises to use a keyword within the ALT attribute on pages...

On a new website I am launching, I have the ability to add an alt keyword to image headers. On multiple pages we have the exact same image but with different keywords associated them inside the alt attribute. The image itself is a collage of different images and so the keywords used can, quite sneakily, match the image.

My question is therefore, will using different keywords on the same image on different pages have a negative effect on SEO?

Thanks,

Stuart

I doubt that using different anchor texts for the same image will have a negative impact on SEO.
After all, a picture is worth 1000 words and since we can't put all 1000 in the alt attribute at the same time, we can put them in smaller groups

Not to forget, that technically even if your image source is the same, what you display can be totally different via CSS so Google can't blame you for using different anchor texts.

I doubt it would have a negative impact, but I would make sure that the alt attribute accurately describes the image. The alt attribute is just a small factor in ranking, so I would not spend too much time on it

Just make sure that you're using the most appropriate image: if you're re-using the same image to target different types of keywords, you might be using images that depict something too broad. You be the judge: if you think it's a good image for the user, I can't imagine it getting you into trouble.
