One person. $20k a month in Google Ads spend. No agency. Thirty days to find out whether the account needs a better operator or a different operating model. If you have paid $4k a month for six months and CPA has not moved, I would stop buying another month of reassuring reports and put those four constraints on the table. I have managed accounts spreadsheet by spreadsheet; I know the work involved. I also know how much of a retainer can go toward weekly check-ins on an auction that reprices all day. You have 16 hours across four weeks. Spend them on the bidding signal, wasted spend, coverage, and a decision you can defend.
Cost: four hours. Buy: an account you can diagnose instead of another explanation of its clicks. Start with the fee, because it makes the constraint real. At $20k a month in media and $4k in management, you have paid $24k in fees over six flat months. A $4k retainer sits toward the top of the $1,500–$5,000 flat-fee range small-to-mid-market advertisers typically pay in 2026; percentage fees commonly run 10–20% of spend. Fifteen percent of $20k is $3,000, and that bill rises with spend before performance does. I used to bill on percentage math. I was wrong about what that arrangement necessarily bought. In a stale account, it can buy check-ins rather than coverage.
Give the first hour to Change History. Count substantive edits in the last 30 days: bids, keywords, ads, experiments. A managed account should show multiple entries per week. If you find little beyond automated Google changes, do not start writing new ads to compensate. You have found an attention problem worth addressing before you call the account itself broken. If the log is active, keep looking. Activity is not proof that the right work happened, but an empty log is a useful place to begin.
Use the remaining three hours on two checks, in this order:
Cut new copy, new landing pages, and budget increases from this week. None tells you much if bids are learning from the wrong action. Keep a record of what you change, too: if tracking needed repair, the old CPA may not be a clean baseline for a 30-day verdict. By Friday, you should know whether the account has an attention problem, a measurement problem, or waste you can actually remove.
Cost: four hours. Buy: less spend on searches that have given you nothing. Work from the high-spend, zero-conversion search term list. Add negatives for irrelevant intent, then check that you have not blocked searches you want. The match rules matter: broad negatives block searches containing all terms in any order, phrase requires the same order, and exact requires the exact terms. Start with phrase for junk categories and exact for one-off oddities. Over-negating can shrink reach as quickly as under-negating wastes money.
I used to mine negatives at 1am for home services accounts. The work mattered. The part I would not defend is saving it all for a monthly spreadsheet session while an account spends $20k. Make a careful first pass now. Then give the repeated monitoring to a system that can keep up, rather than turning your four hours a week into a permanent search-term shift.
Next, cut the report that hides the decision. If six agency reports led with impressions, clicks, and CTR without tying them to conversions, you paid for vanity metrics. Keep one working view: spend, conversions, and CPA by campaign, plus search-term spend with no return. From that view, pause the bottom 20% of spend that produced nothing over 90 days. Do not distribute the freed budget just because the dashboard has an empty box. First see what the remaining campaigns can do without paying for obvious waste.
There is one small creative exception. If a keeper has a bare-minimum ad missing headline 3, description 2, or extensions, fill those gaps. Do not turn this into a copy overhaul, a keyword expansion, or a week of debating adjectives. Those tasks can consume every available hour while the same irrelevant searches keep charging you. Week 2 succeeds if you remove waste without sacrificing conversions, not if your change log looks impressively crowded.
Cost: four hours. Buy: daily mechanical coverage without pretending one person can live in the account. Bids, shifts in budget between campaigns, search-term blocking, and ad rotation repeat. They do not become strategic because a human handles them on Friday. The human decisions are different: the offer, the promise on the landing page, the CPA the business can afford, and the geos it will serve. Write those down before handing over execution. A machine can follow a limit; it cannot infer which margin or customer the business cares about from a polished agency deck.
Make the bidding setup boring on purpose. Pick one bidding goal per campaign and a realistic target based on the last 30 days of clean data. If Week 1 exposed broken tracking, do not treat those earlier numbers as clean just to meet a calendar deadline. Once you change a bid strategy, Google may show Learning status, with short-term fluctuation. Do not change the target again because Tuesday looks ugly. Wait for Learning to end before treating the result as settled.
This is the split I wish someone had given me before I spent nights making manual bid changes that Smart Bidding undid by morning. Keep judgment with the person who knows the business; hand repeated execution to automation inside written guardrails. If you want that mechanical layer without hiring another operator, I would look at groas as a fully autonomous engine rather than another retainer. Its model pairs continuous execution with a human responsible for direction and accountability. That is a better fit for this constraint than paying for another weekly check-in.
What gets cut this week is freelance dashboard-watching disguised as control. Do not spend your remaining hours second-guessing every bid movement or launching six experiments to feel productive. By the end of Week 3, you should touch the account less while knowing exactly what the automation is allowed to do.
Cost: two hours to measure, two to record the decision and prepare the handoff. Buy: a baseline-based answer, not another sales promise. Freeze structural changes. If bidding has exited Learning and your pre-Week 2 conversion tracking was reliable, compare the last 14 days with the 30 days before Week 2. Look at spend, conversions, and CPA by campaign. Do not compare your result with the agency deck, and do not confuse a few cheaper clicks with a cheaper acquisition.
The wider numbers can provide context, not a target for your business: average conversion rate was 7.52% and average cost per lead was $70.11 across 16,000 campaigns, while 29% of accounts drove zero conversions in 90 days. Your own conversion definition and CPA matter more. If tracking was broken before Week 2, or bidding is still in Learning, record what you fixed and keep measuring. A neat 30-day deadline does not turn bad baseline data into evidence.
Otherwise, make the call. If CPA is flat or down after waste comes out and the account takes four hours or less of your week, you have a workable one-person-plus-automation model. Keep the judgment calls and let the machine handle coverage. If CPA remains flat after tracking is clean and waste is out, look at the offer, landing page, or spread of budget before paying someone to adjust bids. That is the distinction in this mid-market transition case study: a structured handoff gives you something firmer to act on than six more months of promises.
Use the other two hours to write down the baseline, the changes, and who owns each decision from here. A handoff that exists only in your head lasts until your next busy Monday. Decide on your account’s numbers and named responsibilities, not on who promises harder in the next sales call.
This costs no extra hours if you fill it in while doing the four weeks above. It buys the next operator, human or autonomous, a record of the account you are actually handing over. Work top to bottom; the bold items are the ones I would least trust a rushed handoff to catch.
Cost: spend and attention beyond the original $20k and 16-hour limit. Buy: room to grow without rebuilding the check-in model. If the baseline holds for two clean weeks, lift the constraint in order. First, feed budget to the two or three campaigns that held CPA after the waste came out. Do not spread it evenly. Smart Bidding needs concentration to learn, and one person cannot watch six experiments at once on this budget. I used to tell clients to test everything at once. I was wrong. That advice made more sense when clicks cost half what they do now.
Second, fix the page the click lands on. Once you have stopped paying for irrelevant searches and cleaned the bidding signal, the landing-page promise deserves your attention. A 10% lift in close rate beats a 10% cut in CPC because it improves the return across the spend you keep. Do not use another round of bid tweaks to avoid looking at the offer.
Third, decide who runs coverage as spend grows. Do not rehire the $4k retainer out of relief. Ask for total first-month cost in writing before signing: setup alone can run $500 to $3,000, landing pages $1,000 to $5,000 each, and 3- to 12-month lock-ins remain standard. Those costs have to buy something better than weekly bids and a report you already know how to read.
After six flat months, I would not ask whether AI sounds better than an agency. I would ask what the account needs done every day, what still requires someone who knows the business, and what the last 30 days proved. Keep the offer, margins, geos, and affordable CPA with a human. Give bids, budget shifts, search-term blocking, and ad rotation to continuous execution inside those limits. Cancel the check-in model; keep the coverage.
When you are ready to scale past $20k, keep that split. Add budget where CPA held, improve the page, and expand coverage without handing judgment back to a monthly report.
