[Help or advice on reducing digital footprint]

I looked for threads on here for help reducing or semi-eliminating my digital footprint - to no avail. So i am posting this to ask how to reduce my digital footprint when i have many different accounts over the years, remembered and forgotten. I know i need to go back and try and individually remove them but i wanted to know if there was an easier way to do this. is there? or how do you 'measure' your digital footprint to know how public or private you are to the internet? if anyone can give me some tips or advice outside of 'go back and individually delete everything' - it would be very helpful. And perhaps it would help others with this also.
