I think SEO services are a scam...prove to me otherwise

I know they probably work, but anyone saying "it's a long game, you just have to spend the money and trust that it'll work" makes me suspicious...

Like, yeah, it works, but if I'm also pushing hard at PPC ads, that gets my name out there, so people might search for me and click on my site "organically" a few months after they search me.

Also, the more blog posts I write, the more products I upload, the more "SEO-friendly" information I'll have on my site.
