I just can't imagine throwing $1,200 per month on PPC type advertising, not on Facebook or even google. I know a lot of people do this, and it can help drum up some clients in the short term. However, that same $1,200 (whether in $$ or time) invested into web development, content creation, SEO and link building will yield 15X more results over the next 5 years.
I haven't run a PPC ad in over 5 - 6 years. I decided organic SEO was the better bang for the buck, albeit a much slower one. Now nearly 100% of my business is coming from Google organic searches. I don't do any cold calling, advertisements, brochures, or any other form of advertising now because I don't have to.
