We have no way to determine if someone is using our new 'more like this datasets' feature or not.

I guess we could possibly use google analytics, but I'm not sure if that would work or not.

One thought is to add a query parameter to the url that states how the user got to the dataset page.

For example we could have the following on our 'more like this dataset' links:

../dataset/<dataset_name>.html?ref=more

We could possibly do the same for search and browse by functionality:
../dataset/<dataset_name>.html?ref=search
../dataset/<dataset_name>.html?ref=browse
../dataset/<dataset_name>.html?ref=topics
../dataset/<dataset_name>.html?ref=project
