Weekly is ideal, but realistically many people do bi-weekly or monthly unless spend is high. The key is having a simple system like regularly adding negatives and grouping patterns instead of full deep audits every time. Even quick checks can save a lot.just did a deep search terms audit a few weeks ago and found around $2k/month of spend going to completely irrelevant queries. I try to do this weekly but honestly it slips. whats your cadence and do you have a system for it or just brute force?
