If you have subscribed to Smart Recommendations, it is important to understand what events are considered Recommendation Impressions.
Klevu allows a merchant to create recommendation banners on pages such as Homepage, Category/Collection Pages, Product Page, etc with various strategies/logic. Anytime a shopper visits any of these pages, an Impression will be registered for the banners visible on that page.
For example, if you have added 1 Klevu recommendation banner to your home and 2 banners on product pages, then when a shopper visits your home page and views a product page, a total of 3 impressions will be considered.
Note: In a case where you have set up recommendation filters/rules that DO NOT yield any recommended products, then impressions will NOT be considered.
