I am running Magento 2.3 with the Porto theme. The problem I have is that every product in my category pages is missing an alt tag.
Any pointers as to where I can fix that would be appreciated.
Magento have default ALT tag on all images but few themes override alt tags of images. Since themes override alt tag so normally category pages of Magento don't show ALT tag of products. You can refer to following link to resolve your issue.

I am having a similar issue with Porto 2.3 ALT on the product page. I do have ALT's and in the inspect page it shows I do. However every SEO scan I run it show everyone of my Product pages is missing the ALT. I have notice this only on Porto Themed Sites. I have submitted a ticket to Porto and they have denied this.
