@ChrisJWilson That sounds like a lot of work. Yeah at least 500 words. Enough to tell me if it is worth trying or to avoid.

You could make this a category on your personal blog. It does not have to be a pro job on it’s own domain if you are not going to monitize. Do it as a hobby with no pressure or schedule. The search engines will index each page anyway.

Example: I don’t have a website dedicated to search engines but my occasional reviews on my persoanl blog get traffic.
