I like the idea of both. FB ads are a great way to snipe out your target demographic with laser precision quickly and even relatively cheaply if you know what you’re doing. SEO is a great way to get anybody and everyone over the long term. I used to be only about SEO since I’ve used it well enough to get half a million hits/month on my site from search…I wouldn’t be able to afford (nor do I want to) pay even $0.01 for any those hits. But to duplicate that level of success each and every time is exhausting for new sites and sometimes just not possible. If you’re know exactly what you’re fishing for, there’s no need to cast the giant net that is SEO.
