Honestly, three income streams. Eighteen months. One very organized Notion database. Let me walk you through exactly what happened when I ran display ads, chased sponsorships, and built an affiliate portfolio on my tech content side by side — and which one actually moved the needle on my real hourly rate.
The Setup: Why I Started Tracking Everything

After eighteen months of consistent tracking, I have some opinions. And I have receipts.

My blog pulls roughly 50,000 pageviews a month. The display ad revenue swings between $200 and $400 depending on
