Frequently Asked Questions

Everything you need to know about our free SEO tools

What is alt text and why is it important?

Alt text (alternative text) describes images to search engine crawlers and users who rely on screen readers. It's essential for both SEO and web accessibility.

Should I include 'image of' in my alt text?

No, screen readers already announce that it's an image. You should start directly with the description to save time for the user.

Can alt text help with image search rankings?

Yes! High-quality, descriptive alt text is the primary way Google understands your images, helping them show up in Google Image Search.

What is the ideal length for alt text?

Keep it under 125 characters if possible. Most screen readers stop reading after that point, so brevity and clarity are key.

Should every image have alt text?

Decorative images (like background patterns) should use an empty alt attribute (alt=''), while informative images should have descriptive alt text.
