Quick fixProduct photos your customer can't identify
A shopper using a screen reader lands on your product page and hears the word "image" — or a filename like "IMG_4471.jpg". They have no way to know what they're looking at, so they leave.
Where you fix itOpen the page → click the image → Design tab → Alt text.
Quick fixHeadings used for looks instead of structure
Screen reader users jump around a page by its headings, the way you'd skim with your eyes. On your pages the headings jump from large to small out of order, so that shortcut breaks and they have to listen to everything.
Where you fix itOpen the page → click the text block → in the text toolbar change the style (Heading 1 / Heading 2 / Heading 3). Use Heading 1 once at the top, then Heading 2 for sections under it — don't skip a level to get a smaller font.
Quick fixLinks that say nothing, or say 'click here'
Screen reader users often navigate by pulling up a list of every link on the page. On your site that list reads "click here, click here, read more, link". It's unusable as a way to move around your store.
Where you fix itOpen the page → edit the text or button block → replace vague link text with its destination. Check header icons in Edit Site Header.
