Google Images is one of the most underutilised traffic sources for bloggers. With a well-implemented image SEO strategy, many blogs derive 15-25% of their total organic traffic from image search. This guide shows you exactly how.
Blogs publish content regularly, covering specific topics in depth. This creates a natural alignment between page content and images — exactly what Google's image search algorithm rewards. A food blog's photos of recipes, a travel blog's destination photos, a DIY blog's step-by-step images — all can rank prominently in Google Images when properly optimised.
| Option | SEO Value | Notes |
|---|---|---|
| Your own original photos | Highest | Unique content Google hasn't seen |
| AI-generated images | High | Unique, but label as AI-generated |
| Licensed stock photos | Medium | Same image on many sites — harder to rank |
| Free stock (Unsplash etc.) | Low | Thousands of sites use same image |
Use descriptive, hyphenated filenames: chocolate-chip-cookie-recipe-close-up.jpg not IMG_4521.jpg
Each image on every post needs unique, descriptive alt text. Don't copy the post title — describe what's actually in the image.
Captions are read 3x more than body text. They also provide keyword context. Use them on editorial and tutorial images.
Target under 80KB for inline blog images. Use Squoosh or TinyPNG.
