You'd be surprised... If you have a poorly optimized website, your own Facebook page can outrank your website. I see it about every day. Keep in mind, if you're not particularly skilled in Google Ads or aren't 100% sure what you're doing, it's a really good way to throw a bunch of money away. Also, the more you optimize for the local 3-pack, the better chance you have of being seen. Not only because it's at the top, but because companies like Home Advisor and Thumbtack can't be in there crowding up the listings.
