Tree merge

Tree merge is a tool I built in order to merge the category systems for all the DIY stores in the UK (see Everydiy).

It increased conversion rates by 100%.

The original issue was that when searching with vague terms, Elastic Search would return too many products.

Using search plus categories allows the user to very quickly drill down to what they are looking for.

Tree merge is described in much more detail at tree-merge.com.
