Before acquiring a domain name, I have a habit of comparing its search volume on Google Trends with a specific keyword to see if it gets a good amount of searches. I use 'exercise ball' because it gets a good number of searches but mainly because its search volume is constant so it is not influenced by temporary circumstances.
Do you also use this benchmarking method? If so, what keyword(s) do you use?
