On iOS luckily enough I found Apple Maps to have crossed the good enough threshold for most of my purposes and area, except for the occasional live and timetable transit info.
Those are not advertisements. There is nothing to ignore. Google is not paid to show me those, and they fight link-spammers every day to attempt to get the best organic results.
I find Google's search results ads to be exceedingly easy to ignore. I also find them useful and sometimes click them.
Please tell me how to ignore google search and google maps.
