What are the downsides of auto-generated categories?
The categorization from your webshop might be very specific. If this is the case, the generate categories functionality might exceed the maximum number of generated categories (which is 20 pages). However, usually the categorization of the platform you're trying to send your items to is often less specific than your own categorization.
What we see often is that users set a lot of rules to send many very specific categories to the same category of the export platform. This can cause a lot of unnecessary extra work. In addition to the extra work, completing 20 pages of generated categories probably won't categorize 100% of your items, as our maximum capacity have been exceeded.
To avoid extra unnecessary work and to make sure you actually end up categorizing 100% of your items, work smart in your categories. Instead of blindly matching all of your very specific categories to the same (less-specific) category on the export platform, look for keywords that appear in multiple categories and use the "contains" operator to categorize them. The image below describes what we mean by that.
