Question 1

What is image alt text and why does it matter?

Accepted Answer

Alt text (alternative text) is a written description of an image that appears in HTML code. It serves two critical purposes: helping visually impaired users understand images through screen readers, and helping search engines understand and index your images for better SEO rankings.

Question 2

How long should my alt text be?

Accepted Answer

Keep alt text concise but descriptive, ideally under 125 characters. Screen readers may cut off longer descriptions. Focus on the most important aspects of the image and avoid unnecessary words like 'image of' or 'picture of'.

Question 3

Should I include keywords in my alt text for SEO?

Accepted Answer

Yes, but only naturally. Include relevant keywords that accurately describe the image, but never stuff keywords unnaturally. Alt text should primarily serve users, not search engines. Focus on clear, descriptive language that benefits both accessibility and SEO.

Question 4

When should I use empty alt text (alt='')?

Accepted Answer

Use empty alt text for purely decorative images like design elements, icons, spacers, or images that don't add informational value. This tells screen readers to skip the image, preventing unnecessary interruptions for visually impaired users.

Question 5

What are common alt text mistakes to avoid?

Accepted Answer

Avoid these mistakes: leaving alt attributes completely missing, using generic descriptions like 'image' or 'photo', including file extensions (.jpg, .png), keyword stuffing, using 'image of' or 'picture of' prefixes, and writing overly long descriptions that exceed 125 characters.

Question 6

Does missing alt text affect my Google rankings?

Accepted Answer

Yes, indirectly. While missing alt text isn't a direct ranking penalty, it negatively impacts user experience and accessibility, which are ranking factors. Additionally, images with proper alt text can appear in Google Image Search, driving additional traffic to your site.

Question 7

How often should I audit my website's image alt text?

Accepted Answer

Run an image alt text audit whenever you add new content with images, at least quarterly for existing pages, and especially before major SEO campaigns or accessibility compliance reviews. Regular audits ensure your site remains accessible and SEO-optimized.
