From my experience managing PPC campaigns, there isn't a guaranteed way to make a restarted campaign perform exactly like it did before. The campaign settings are only one piece of the puzzle. Search demand, competitor activity, bidding algorithms, audience behavior, seasonality, and even economic conditions are constantly changing behind the scenes. Rather than expecting identical results, I now treat every relaunch as a fresh optimization process. I monitor the data carefully, avoid making quick decisions, and give the campaign enough time to settle before deciding whether changes are actually necessary.
