Here are the basic facts:
Google is the largest search engine.
Facebook is the largest social network.
Like it or not, these are the two primary options for making your brand visible online and attracting new customers/clients to your business. The differences between them don’t necessarily make one better than the other. Ultimately, it’s important to find where you can be most successful. Try both! Just be thoughtful with strategy. Consult on your needs from experienced PPC managers to put your best foot forward.
