Option 1: do it yourself (free, but it won't happen)
The weekly routine is simple, but "when I get time" means it slips, and the leaks reopen. If you are honestly too busy, DIY is free in money and expensive in missed waste. See the manual routine if you want to try.
Option 2: hire it out (works, but pricey)
An agency or freelancer takes it off your plate, but costs a retainer plus often a percentage of spend — a lot for what is mostly routine daily work.
Option 3: automate the routine (lowest effort)
The fit for a busy seller is usually software that does the daily work and only asks you to glance at it. AIAdKing runs bids, negatives and dayparting every night, writes a plain-English summary, and previews changes in shadow mode — minutes of supervision instead of hours of management, at a flat fee.
