Welcome to the Q&A Forum

Hi, What's the URL & What keywords are you tracking?

GTM allows a great deal of tracking capabilities without having to use a programmer to modify your code. Better tracking equals the ability to make better decisions and determine what is and isn't work.  Google Search Console keeps an eye on the "heartbeat" of your website and helps you see any issues that Google may have with the technical aspect of your website.  Both free and both great tools. The better question to ask would be, "What should I do if my agency DOESN'T ask for or use these tools?" If an agency isn't tracking performance and using that data to continually improve, I'd be questioning the agency.

Thank you!!! These questions are golden! I agree. It's important to see if they have a good understanding of how to measure and track our goals. We ultimately want to make sure that our investment in an SEO agency has a good ROI. Thanks again! I appreciate all of the help!
