Avoid: “image product shoes best shoes buy shoes”

Chart: “Monthly orders rise from January to June; full figures in the table below.” Provide the detailed data nearby.

05 / QUICK ANSWERS
Alt text questions, answered.
What is alt text?
Alt text is a text alternative that conveys the purpose or information of an image. It is commonly stored in the HTML alt attribute and read by assistive technology.
How long should alt text be?
Use the shortest wording that communicates the image’s purpose clearly. One sentence, often around 80–125 characters, is a practical writing target, not a WCAG character limit. Explain complex charts in nearby text or a data table.
Does alt text affect SEO?
Alt text helps search engines understand images in context. It does not guarantee rankings; describe the actual image naturally and avoid keyword stuffing.
Do decorative images need alt text?
Purely decorative images should normally use an empty alt attribute, alt="". Do not simply omit the attribute. If an image is a link or conveys information, describe its function or meaning instead.
Can I generate alt text in bulk?
No, this preview does not support bulk processing or AI generation. You can preview one image at a time and write and copy your own description.
How do I add alt text in Shopify?
Open the image’s details in Shopify, edit its alt text field and save. For product images, start from the product’s media section. This site does not connect to Shopify or update your store automatically.
