FAQ

Frequently asked questions

Why is Image SEO important?

Optimized images improve page load speed (a core ranking factor), provide better accessibility, and allow your site to appear in Google Image search results.

What makes a good Alt Text?

Good alt text should be descriptive and include relevant keywords naturally. Instead of 'image1.jpg', use 'Hand-crafted ceramic coffee mug on wooden table'.

Why use local scanning for images?

It's 100% private. Your HTML source is processed entirely in your browser, ensuring your private content isn't sent to our servers.

How large should image files be?

For web pages, aim to keep most images under 200kb. Large hero images should be compressed and converted to modern formats like WebP for maximum speed.

What is 'Image Weight'?

Image weight refers to the file size. Heavy images (megabytes) are the most common cause of slow loading times and poor mobile SEO performance.

Does the filename matter for SEO?

Yes! Use descriptive filenames like 'best-coffee-maker-review.jpg' instead of 'DSC_001.jpg' to provide more context to search bots.

What is the difference between Title and Alt tags?

Alt tags are for accessibility and SEO context. Title tags are for the small tooltip that appears when a user hovers over an image. Alt tags are significantly more important for SEO.

Should I use captions?

Captions provide extra context for both users and search engines. They aren't required but can improve user engagement and time on page.

Is this tool free for startups?

Yes, our Image SEO Assistant is 100% free for all businesses and creators looking to optimize their visual assets.

How do I fix large image files?

Use our 'Social Media Image Optimizer' to compress your heavy assets before uploading them to your website.

What is WebP?

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for web images compared to JPEG and PNG.

Can I use emojis in Alt text?

It's not recommended. Screen readers often struggle with emojis in alt text, which can degrade the accessibility score of your site.
