I remember posting almost the same question two years ago, broke and tired of spammy “growth hacks.” What actually moved the needle wasn’t another tool – it was understanding where my few dollars got actual returns. For SEO, I learned to write for questions my customers type into Google at 11pm. For email, Kit (free tier) and plain-text newsletters outperformed every fancy template. But the missing piece was always targeting: who sees my stuff, when, and how much I’m willing to pay for a real click. I ended up using a DSP here because it lets me run on CPM or CPC without a monthly retainer, and the reporting dashboard doesn’t hide fees. For a small business, that kind of transparency is worth more than any agency’s pitch.
