- [Do image or video product ads perform better?](https://framepx.com/blog/image-or-video-product-ads.md): Neither wins everywhere. Images are fast and cheap to run at scale, video shows more. Start with images for every product and test video where it earns it.

- [How do you show price and discount badges on ads automatically?](https://framepx.com/blog/automatic-price-and-discount-badge-on-ad-images.md): If you tie the price and discount badge to your feed instead of typing them into the image, the ad updates itself when the price changes.

- [From Feed to Creative: Scaling Product Ads Without Losing the Brand](https://framepx.com/blog/from-feed-to-creative-scaling-product-ads.md): Templates, not designers, scale product advertising. How placement constraints, feed-field bindings, and render-time validation keep automated creative on-brand.
