I learned about pop-up advertising by accident when I was looking for ways to make money in arbitrage. At first, it seemed like the format was outdated, but I came across an article that explained and how to use it correctly in 2025 — taking into account new algorithms and requirements. There were real cases, and one of them matched my niche. I tried it — and the traffic really started flowing. Now I look at pop-ups completely differently. If anyone is interested in affiliate marketing, I recommend looking at that article — it helped me a lot.
