Ok to start with I have to admit that I am not a web developer by any means. My knowledge of HTML and CSS is incredibly basic. Though I want to share from that perspective as I am sure most people reading this are in the same boat. If you are a developer and are looking for more advanced techniques than I encourage you to jump right back to Google to continue your dive.
This kind of response is one I have heard multiple times from people who have tried tackling the world of Google advertising, especially in the nonprofit world. Though Google wouldn't be where it is today if this was true. I also know that many of the nonprofits I have worked with would not have seen the growth they have over the years if you removed Google Ads from the equation.
