For example: There are many web agencies that do not provide direct access to the Google Ads tool, even though it is very easy to give clients access to this tool via an email from the client. This is how a client who was investing $1000 per month in Google Ads and was not getting the returns he was expecting, found out from a friendly employee in the agency that only 40% of the budget was really invested in buying the ad in Google, which means that this agency was taking 60% ($600 per month) in management fees despite the fact that they were telling the client that only 10% was being charged in management fees. You have the right to know how and how much money was invested in buying your ads in Google.

This is the place in Google Ads from where we provide access to our clients' Google Ads campaigns. As you can see, with this direct access to Google's reports, the client can know exactly what Google charged, which means how much money was invested to buy advertising for your business. Here you can see the real performance reports that come from Google and more.
In the Change History section, you can also see all the optimizations that have been made to your Google Ads campaigns in the last two years. This is very important, because some agencies leave your campaigns inactive, meaning they don't do any optimization even if your campaigns are doing badly, or the person in charge of the optimizations doesn't know how to make your investments with Google Ads profitable. Generally speaking, when a Google Ads campaign is not optimized to its maximum profitability, it should be optimized daily.
