You can make sure that some products are never pushed to visitors in the automated campaigns such as the AI wishlist or the Best Sellers campaigns. To do so, inside the campaign builder, click on the "Exclude products" section.
When you define product exclusions in one campaign, these will be shared with all other campaigns.
You can enter several search terms and separate them using commas: ","
You can exclude products using the following methods (without the apostrophes)
Exact title - for example "Blue summer socks"
Partial title - for example "sweater", which will match "Yellow summer sweater" but also "Red winter sweater"
Product id - for example "id:435345555" (make sure to include "id:" in front)
Product tags - for example "tag:t-shirts" (make sure to include "tag:" in front)
Product handles - for example "handle:bundle-product" (make sure to include "handle:" in front)
An example of a complete list of products exclusions could therefore look like:
Blue summer socks, sweater, id:45443454545, tag:t-shirts, handle:bundle-product
