I always go back to this list every year or so to look through the major ones. At least for my relatively unpublic life, I have never gotten readded after the initial time I went through to delete everything. YMMV if you are more prolific with your public persona than I am, but like other comments have said, don't trust those 3rd-party services to do this for you because many use Mechanical Turk type of labor with your personal info to basically walk through this list themselves (i.e. people that might keep your PII for nefarious identity theft purposes).
Edit: one thing I have that helps a lot that is unique is that my name is a slight misspelling of a famous athlete in a sport that is not at all popular where I live. When people search "_huayra_", they usually get results for "_huayrack_ the legendary athlete in some far-flung non-mainstream sport", in a sense.
