Yeah, as a very general tool I think they work somewhat interchangeably among similar countries, though this one has a few specifically US-centric questions that were more difficult to answer. (I just pretended I was American for all of them.)
It absolutely has its faults, but I've always found the two-axis political compass to be the best at more generally arriving at a person's ideology outside of country-specific questions. I take that every few years and keep screenshots of my results to track my trajectory.
As a related point of conversation, something I've always had trouble with a lot of these tests is whether I should answer based on my philosophical or practical beliefs, as there's a bit of a divide there at least for me. Furthermore, the simplified nature of these tests can't really paint a full picture of an individual's beliefs. While any tests will place me on the left libertarian end of the spectrum, my beliefs aren't quite so binary. I consider myself a leftist, but the political philosophy that shaped my beliefs runs the gamut from anarchism & Marxism to classical liberalism and even select conservative philosophers (albeit from previous eras, and I do mean select).
