Alt Text
Descriptive text added to images that tells search engines and screen readers what the image shows.
Alt text (alternative text) is a written description of an image in your HTML code. It serves two purposes: it helps visually impaired users understand images through screen readers, and it tells search engines what an image depicts since they can't "see" pictures.
Good alt text is specific and concise. Instead of "image" or "photo," write "golden retriever puppy playing fetch in a park." Describe what's actually in the image, not what you wish was there.
Don't stuff keywords into alt text. Writing "best SEO tool free SEO audit SEO scanner" as your alt text is spammy and helps nobody. Describe the image naturally, and if a relevant keyword fits, great.
Decorative images (like background patterns or spacer graphics) should have empty alt attributes (alt="") so screen readers skip them. Not every image needs a description — only ones that convey meaningful content.
Why It Matters for SEO
Alt text helps your images appear in Google Image search, which drives real traffic. It's also essential for web accessibility — without it, screen reader users miss your visual content entirely. Google uses alt text as a ranking signal for image search results.
