Image alt text and heading checker.

Writing good alt text

Alt text is read aloud by screen readers and shown when an image fails to load. Search engines use it to understand images, and it helps images appear in Google Images. Good alt text describes what the image shows and why it's there, in a short sentence.

• Describe, don't label: "Technician fitting a solar panel on a terraced roof" beats "solar panel".
• Skip "image of" or "photo of": screen readers already say it's an image.
• Keep it under about 125 characters.
• Include a keyword only where it naturally describes the image. Don't stuff.
• Use alt="" (empty) for purely decorative images such as dividers and background shapes, so screen readers skip them.
• For an image that's a link, describe where the link goes.

Heading structure, simply

Headings work like a table of contents. There should be one H1 that says what the page is about. H2s are the main sections, H3s the sub-sections inside them, and so on. Skipping from H2 to H4 is like a book jumping from chapter to sub-sub-section.

Screen reader users navigate by headings, and search engines and AI tools use them to understand which part of the page answers which question. Pick heading levels for structure, not for their size: change the look with CSS.

Beyond the basics

Well-structured headings phrased the way people search ("How much does a website cost in Lahore?") are among the things AI assistants quote most.
