Image SEO: Best Practices for Ranking in Google Images

You’ve got killer images on your site—but are they bringing in traffic? If not, you’re missing out on free Google Images traffic that could boost your visibility and conversions.

Most people think SEO is just about text. Wrong. Image SEO is a game-changer, and if you’re ignoring it, you’re leaving money on the table.

Let’s fix that.

Why Image SEO Matters

Google Images drives 20%+ of all web searches. That’s a massive chunk of eyeballs you could be capturing. But most websites screw this up by:

• Uploading huge, unoptimized files that slow down their site.

• Using generic filenames like IMG_1234.jpg.

• Skipping alt text, captions, and structured data.

If your images aren’t optimized, they’re invisible. Let’s change that.

Image SEO Best Practices (That Actually Work)

1. Optimize File Names Before Uploading

Google reads file names to understand your image. Ditch DSC00234.jpg and use:

• Descriptive names: blue-running-shoes-women.jpg

• Hyphens, not underscores: Google prefers blue-shoes.jpg over blue_shoes.jpg.

2. Compress Images Without Losing Quality

Slow-loading images hurt rankings. Use:

• TinyPNG (free)

• ShortPixel (bulk compression)

• Squoosh (by Google)

Aim for under 100KB for most images.

3. Write Killer Alt Text

Alt text tells Google what your image shows. Do this:

• Be specific: “Nike Air Max running shoes for women” instead of “shoes.”

• Keep it under 125 characters.

• Don’t keyword-stuff—make it natural.

4. Use Captions & Surrounding Text

Google looks at context. If your image is about “best DSLR cameras,” the text around it should mention that.

5. Leverage Structured Data (Schema Markup)

Want rich snippets? Add Schema markup for images. This helps Google display your images in featured snippets and knowledge panels.

6. Choose the Right File Format

• JPEG: Best for photos.

• PNG: Best for graphics/logos (transparency support).

• WebP: Next-gen format (smaller + faster).

7. Add Images to Your Sitemap

Submit an image sitemap in Google Search Console. This helps Google index them faster.

FAQs on Image SEO

Q: Does image size affect SEO?

Q: How do I check if my images are indexed?

Go to Google Search Console > URL Inspection Tool and check if your images appear in the report.
