Show HN: Tried a Google Ad campaign and failed

Hi all! I tried Google ad for my SaaS (MediaFa.st), but ended up loosing $50 over 4 days.

Today I made my second attempt and I can recommend to all - research or ask someone who knows first, may save you tons of time and money… For example I only today learned that there are 2 types, and I used maximum spread one (shows everywhere, YT, apps, websites etc) and it didn’t work, but there is a search focused one and this one may generate real traffic!
