From my personal experience running a mid-sized crypto blog, finding quality traffic sources that actually convert was a real challenge. I tried a few popular options—some gave volume but poor engagement, others were just too expensive for what they delivered.
One platform that surprisingly worked well for me was 7SearchPPC. It’s not as mainstream as Google or social platforms, but that’s kind of the advantage. The traffic is more targeted, especially for niche crypto audiences. I ran a couple of test campaigns promoting a DeFi guide and a wallet comparison article, and I noticed lower bounce rates and slightly better time-on-site compared to traffic I bought from more generic ad networks.
That said, it's not magic—you still need solid landing pages and good offers. But if you're looking for affordable PPC options tailored to crypto, 7SearchPPC might be worth trying. I wouldn’t say it’s the “best” universally, because every site and audience behaves differently, but it was definitely one of the few networks where I saw a decent ROI without burning through my ad budget.
Also, experiment a bit before scaling up—small A/B tests helped me fine-tune the audience targeting. Hope this helps someone navigating the crypto traffic maze.
