Turn every product image into SEO traffic
The problem: Most galleries use generic captions like "Product image 1" or require manual alt text for hundreds of images—hurting SEO and accessibility.
PhotoSwipe Pro with AI SEO analyzes each image and auto-generates:
- SEO-optimized alt text for better image search rankings
- Descriptive captions that convert browsers into buyers
- ImageObject schema that search engines love
All without manual work. All without slowing down your site.
See it in action
Try the demo below: The images start with generic placeholder captions (what you'd write manually). Enable AI generation with a license key to see AI-powered, SEO-rich descriptions instantly.
👉 How this demo works:
- Without AI: Images show generic manual captions ("Running shoes — example caption")
- Enter license key (format:
pswp_demo_xxxx
) and click "Save key" - Enable AI by checking the box, then click "Generate" on each image
- Watch: AI analyzes the image and writes SEO-optimized alt text + captions
- Bonus: Click "Show JSON-LD" to see the ImageObject schema for search engines
