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 itProducts → open the product → click the image in Product gallery → fill the Alt text field in the media panel.
Quick fixText too faint to read
Light grey text on white is invisible to a lot of people — including anyone over 50 with normal age-related vision, and anyone shopping outdoors on a phone. This one quietly costs you sales from customers who never complain.
Where you fix itAppearance → Customize → Colors, or your theme's typography settings. Darken body text and any grey 'sale price' or 'shipping note' text.
Developer fixCheckout fields with no label
At checkout, a shopper hears "edit text, blank" and has to guess whether the box wants their address, their city, or their card. Most people abandon the order right here. Checkout form problems are among the most commonly cited issues in web accessibility complaints.
Where you fix itCheckout labels usually come from your theme or a checkout-fields plugin. Ask its developer to add a real <label> for every field; placeholder text is not enough.
