Spectare uses a multi-armed bandit algorithm to select images. Each image in your library can be tagged with audience affinities and buying-stage affinities so the engine learns over time which visuals convert best for each segment. An image tagged for developers and the consideration stage will be weighted more heavily when those signals are detected.
Images are now organised into purpose-specific pools using a usage tag you assign in the media library. Overlay images, intended for hero components that place text and a CTA button on top of the visual, are drawn exclusively from the pool tagged as overlay. This prevents a product screenshot or a busy infographic from being placed behind copy where contrast would make it unreadable.
When you upload or tag an image in the admin, the Usage selector lets you designate it as an overlay image or leave it available for general use. Selecting overlay triggers a 16:9 preview so you can judge composition before saving. Images without the overlay tag remain available for all other component types.
The selection algorithm runs independently for each pool, meaning conversion data from general-use images does not pollute the ranking of overlay images and vice versa. Each pool develops its own performance history, which makes optimisation faster and more accurate as your library grows.
