Why has recommendation revenue, CTR or CTP increased/decreased?

There are multiple factors which can contribute to an increase or decrease in engagement with recommendations and their performance on your site.

These can be for example one or more of the following:

1. Placeholders - products which are unknown to Episerver Personalization (i.e. products not in feed)
2. Incorrect product information in feed (e.g. attributes, categories, prices etc.)
3. Site structure change
4. Change to product feed structure/changes to ref codes
5. New season launch
6. Sale period/price adjustment
7. New AB test/new test group rolled out
8. Changes to merchandising/strategy on site without AB testing
9. Recent change in marketing activity
10. Expansion to other markets/channels
11. "markAsShown" functionality added/removed/broken
12. Recent changes/problems with revenue tracking
13. Problems with page tracking
14. Recent issues with serving recommendations
15. Changes to recommendation position
16. Changes to recommendation size
17. Changes to number of recommendations served
18. Changes to pages showing recommendations
19. Changes to recommendation styling (price, title, star ratings etc)
20. Recently underwent re-platforming
