Question 1

What is alt text and why is it important?

Accepted Answer

Alt text (alternative text) is an HTML attribute that describes the content of an image. It serves two critical purposes: it makes images accessible to visually impaired users using screen readers, and it helps search engines understand what your images contain for image search rankings.

Question 2

How does alt text affect SEO?

Accepted Answer

Alt text is a key factor in image SEO. Google uses alt text to understand image content and context. Well-optimized alt text helps your images appear in Google Image Search results, driving additional organic traffic to your website.

Question 3

What makes good alt text?

Accepted Answer

Good alt text is descriptive, concise (under 125 characters), and naturally includes relevant keywords without stuffing. It should accurately describe the image content while providing context about why the image is on that particular page.

Question 4

Should decorative images have alt text?

Accepted Answer

Decorative images (like background patterns or dividers) should have empty alt attributes (alt=""). This tells screen readers to skip them. Only meaningful images that add content value should have descriptive alt text.

Question 5

How is this different from image captions?

Accepted Answer

Alt text is hidden in the HTML and read by screen readers and search engines. Captions are visible text displayed below an image. Both are valuable for SEO, but alt text is specifically designed for accessibility and image search optimization.
