I have very general blogs on celebs, fitness, etc. Get decent traffic but a low CTR. Two months ago I was making $1 a day; and now it's up to $3. Haven't done anything new, just kept posting new content.
$1 per day is a good start man, some suffer from years before gaining this kind of value in a day lucky for you to earn this much in a day, the only thing you need to do is how to make it multiplied twice
personally i think adsense is a waste of time you need load of work and effort to try to reach for a few dollars
