Citation Builder is my favorite service. It's allowed us to scale our Local SEO business without hiring the amount of workers it would take to do citations for every client.
I have used several different citation tools but BrightLocal is still at the top of my list, the citation building and tracking resources are perfection!
Citation Builder saves our agency hours every month at a low cost. It works on all the important citation sites and the support team will fulfill all of your requests promptly.
