Launched a Paid Search Campaign

So far I've primarily been "marketing" by being active in some maker communities (like Indie Hackers) and submitting NullBox to some project/product/startup registries. So far this has driven over a dozen trial users and even a paying user (who's brought greater feedback) but it's admittedly not very targeted. Maybe some of the people seeing NullBox through my efforts thus far have the problem I'm trying to solve, but that's more by luck than anything else. So I've decided that the product and landing page are in pretty good shape (but always with room to improve) so it was time to pull the trigger to spend a little bit of money trying to target my real user market with paid search ads (Google Ads) to try and get a better sense of market validation.

Additionally, I'm going to try to start targeting user communities that are likely to be more specifically potential users as a separate effort. Both through organic involvement in those communities as well as seeing if I can get paid advertisements in those spaces.
