Congratulations, you’ve finally created a popular abode for the denizens of the web. I guess the next step is attempting to monetize it! Chances are you’re thinking about putting ads on it.
One import thing about putting ads is that you’ve obtained your current positioning by putting content and users first. While it’s great to use the above heat map from Google Ads, it’s also very import to note that they’ve specified to think about how your users use your site, and to also put your users first.
There is a diminishing marginal return on ads. More ads do not mean more money. In fact, it might negatively impact the revenue on other ads, so it’s very important to take the placement, saturation, user-base, and usage of your site into account before placing ads willy-nilly. The heat map is used more as a “guideline” more so than the end-all-say-all of ad placements.
Your site is valuable to advertisers because users go to it; the users find it valuable for it being what it is. If you change what your site ultimately is, your user-base might react negatively to it, and your site can no longer be as effectively monetized.
