Before signing on the dotted line, you should always get to know an agency.
Do they seem interested in your business, your industry, and your personal goals? Are they interested in learning about your online presence so far, and what kinds of keywords you’re interested in targeting?
If not, they may not be the agency for you.
You should strive to find an agency that immerses itself in your industry to learn about your business, your competition, and how to make a PPC campaign as effective as possible.
