Tips ↑ Back to top

Optimize Placement ↑ Back to top

Make sure that “Top Rated Alternatives” are offered at a very prominent position in the product page, ideally before all other recommendations:

  1. Navigate to WooCommerce > Recommendations > Locations.
  2. Go to the Product section.
  3. Click the After Product Meta tab.
  4. Drag the “Top Rated Alternatives” Engine deployment to the top of the list.
  5. Save your changes.
If the currently viewed product is out of stock, Engine deployments in the After Add-To-Cart Button Location will not be displayed. In this case, deployments in the After Product Meta Location will be the first to be displayed.

Notes on Full Page Caching ↑ Back to top

If your server is configured to serve cached content/pages, the recommendations generated by the “Top Rated Alternatives” Engine may:

  • fail to display correctly; or even
  • not be rendered at all.

To get these recommendations to display properly for visitors without an active session, you can use an alternative method for rendering recommendations that will bypass your server’s page cache on these pages:

  1. Go to WooCommerce > Settings > Recommendations.
  2. Locate the Deployments rendering > Use AJAX option and enable it.

Note that enabling this option may introduce a noticeable delay between the time that a page has fully loaded and the time that recommendations become visible to visitors without an active session. This delay will depend on the speed of your server, and the quality of your each visitor’s network connection. If this is an issue, the next option is to completely disable the page caching features enabled on your site/server (not recommended!).
