You need a new roof, so you go to Google and search through half a dozen roofer’s sites. One saavy roofer has Facebook advertising tools installed on their website. Later, you log onto Facebook and see an ad from the saavy roofer you were looking at. You see a few more of their ads throughout the week, cementing their brand in your mind
When deciding on w.hich roofer to use, that saavy roofer will stand out among the rest.
The roofer converted a simple Google search into a sale through Facebook ads. Even after you left their website, thier Facebook ads brought you back.
