Your recommendation widget is empty or missing. Recommendations need three things in place: a feed, tracking, and a spot to render.
Check these
- Is the catalog feed connected and fresh? No feed (or a stale one) means nothing to recommend. See setting the product / content feed.
- Enough data for the algorithm? Behavioral algorithms (viewed-together, trending) need interaction history. On a new site or a cold catalog, they can return little — set a fallback (e.g. best-sellers or newest) so the widget is never empty.
- Filters too strict? In the recommendation settings, over-tight filters (in-stock only, one category, price band) can filter everything out. Loosen them and re-check.
- Is the widget placed? The action needs a placeholder or selector that exists on the page. Confirm in the QA Simulator.
- Interaction tracking on? Product events (view, add-to-cart, purchase) power the models — confirm they’re firing.
The Product Recommendations Wizard walks through algorithm choice, filters, and fallbacks end to end.
