I spent a Friday night mining search terms for a home services account spending about $20k a month. Two hundred rows in, I was still paying for clicks from people looking for jobs, training, and DIY advice. I’d done work like that for years. Of the 11 recurring Google Ads jobs that ate my weeks, I’d hand eight to an autonomous engine today. Three still need a human, and the sales decks rarely say which three.

This list is for owners and in-house marketers asking whether an AI agent can run copy, bids, budgets, and the rest without turning the account into an expensive experiment. For each job, here’s what I did by hand, what changes when an engine takes over, and the first thing I’d check.

1. Mine negative keywords before they eat a week of spend

By hand, this was the 1am job: export the search terms report, filter for zero-conversion clicks, and stare at variants of free, jobs, DIY, and competitor names until I decided what to block. Miss a week and you could fund a pile of clicks that never had a chance.

The advantage of an engine is timing, not a prettier keyword report. Older scripts often waited for statistical proof. One veteran script builder describes the problem: at $50 to $70 per click in auto insurance, waiting for 100 clicks on a plainly irrelevant term could burn around $7,000 before the script acted (his breakdown). An engine that reads intent can block clear junk sooner while holding uncertain terms for review. I would not let it add every negative it dreams up.

Verdict: hand it over, with a threshold. First step: ask what confidence triggers an automatic negative and where you can review terms it held back.

2. Keep the match type structure from rotting

Exact for control, phrase for reach, broad only if you watched it like a toddler near traffic. That was my religion for years. Then Google changed what those labels mean: modified broad was folded into phrase in February 2021, and exact had already begun matching same-meaning rewrites in 2018. My old structures needed more pruning, not more reverence.

The stakes rise with spend. In a study of 30,000 accounts, broad dominated spend while exact’s share had fallen 9.5 points since 2022 (the breakdown). WordStream’s audit of 13,474 US search campaigns puts average CPC at $5.42 and cost per lead at $66.69 (its figures). Loose matching at those prices gets expensive fast.

An engine can read the query, bidding strategy, and negative-keyword foundation together, then decide whether a term needs its own exact home or belongs under broad with guardrails. There is no match type worth defending regardless of CPA. A separate study found exact leading on CTR, conversion rate, and ROAS with lower CPA, while broad offered scale that varied by bidding strategy (the summary).

Verdict: hand it over. First step: demand CPC and CPA by match type for your account. If the tool cannot show them, it is not managing structure; it is just spending.

3. Write ad copy and stop nursing weak tests

I ran the same tired test for years: swap one word in three headlines, wait four weeks, declare a winner that moved CTR 0.4 points and did nothing for CPA. I used to call that discipline. I was wrong. It was stalling.

Responsive search ads can assemble combinations from up to 15 headlines and four descriptions. Google can also create assets from landing pages, existing ads, and ad-group keywords, then select combinations it predicts will perform well (how Google describes it). That gives an automated system more combinations to work with than I could launch and inspect by hand. It does not make every generated claim safe to publish.

An engine that writes from the page, keeps required language in place, and retires weak assets earns its keep here. Hand over production; keep visibility into what went live. You can inspect added assets in the Asset report’s source column and turn off automatically created assets in Settings.

Verdict: hand it over, but keep the audit. First step: check that report weekly for the first month, and pin a guarantee or price that must appear exactly as written.

4. Set bids without strangling the campaign

By hand, I adjusted device bids and hoped Monday looked like last Monday. Smart Bidding made that routine look quaint: it prices auctions using signals I could not inspect or respond to one by one. The remaining work is setting a sensible target and giving the system room to learn.

I learned the second part by pushing a tROAS target up 30% to “force efficiency.” Volume shrank for two weeks. One practitioner calls unsupervised agents interns with terrifying confidence: they can propose budget and ROAS changes with tidy explanations while missing account details such as portfolio bid limits (his warning). Clean reasoning is not the same as account context.

An engine that watches performance intraday, respects a floor and ceiling, and records why it moved a target beats my monthly fiddling. The guardrail is part of the automation, not a concession to it.

Verdict: hand it over inside a range you set. First step: write down the permitted target range and require a logged reason for any move outside it. If you cannot see that log, you cannot tell management from meddling.

5. Shift budget before the month is gone

I used to move budgets once a month, usually after the waste was obvious. Brand was capped while a non-brand campaign with a $68 CPA starved. I told the client we would fix it next month. That delay was part of the operating model.

A pricing guide puts agency management at $1,500 to $10,000 a month or 10 to 20% of spend (its figures). Paying for management does not, by itself, make someone available to move money tonight. An engine can compare marginal cost per conversion across campaigns daily and feed the stronger opportunity first. If another $100 in campaign A buys two conversions at $50 while campaign B buys one at $100, the reason to move budget is not mysterious. The valuable part is making and recording the move while it still matters.

Groas works bids, keywords, and budgets around the clock for one flat $1,499 a month per service, whatever you spend. Judge that work by its action log, not a green arrow in a monthly report. I spent enough half-days writing reports that described spend and CPA without naming a single useful change.

Verdict: hand it over. First step: ask what rule moves budget, how quickly it acts, and where you can see one move and its reason.

6. Match landing pages to search intent

I once sent 40 ad groups to one generic service page because building 40 pages was a quarter of work nobody had approved. The click arrived with a specific need; the page greeted it with a vague service pitch. Conversion rate paid for that mismatch.

The fix is not glamorous. Put the offer the searcher came for on the page, answer the need near the top, and make the next action clear. Groas builds a landing page for every ad group on search accounts. That matters because ad management that stops at the click leaves a large part of the outcome untouched. A closer page-to-query match can improve landing-page relevance and give the visitor a clearer path to convert. It still has to be checked against what the business actually offers.

Verdict: hand it over. First step: pick a high-spend ad group and compare its search intent with the first screen of its landing page. If they make different promises, fix that before buying more traffic.

7. Catch a broken landing page before paying for a week of traffic

A client swapped a landing page on a Friday without telling me. The headline and offer disappeared, bounce rate doubled by Monday, and Quality Score followed it down. I found the change in a weekly check. The account had kept buying traffic in the meantime.

This is a monitoring job, and a weekly human check is too slow for a broken page. An engine that checks pages daily can spot a missing headline, a broken form, or a load-time spike and respond instead of continuing to send paid clicks to a promise the page no longer keeps. Pausing an affected ad group is better than discovering the problem in next week’s spreadsheet. Rolling a page back is only an option if the system has that ability and permission.

Verdict: hand it over. First step: ask what the system monitors beyond bids, how it alerts you, and what it can do in the first hour after a page breaks.

8. Triage search terms while a launch is still young

The first 14 days can decide whether a launch learns or bleeds. I built tight lists, let broad run too loose, then spent week two explaining spend on near misses. That is negative-keyword work at a different tempo: a new account or campaign has not yet shown you its full vocabulary.

The useful routine is sort, contain, then promote:

  1. Block terms whose intent clearly cannot turn into a customer.
  2. Contain uncertain terms rather than letting them consume the whole launch budget.
  3. Promote proven queries into a tighter structure with a page that matches them.

None of that helps if it waits for my Friday review. Continuous execution makes launch triage more valuable than a polished launch checklist, provided I can see the reasons for what was blocked and promoted.

Verdict: hand it over. First step: on day three, look for decisions on search terms and the reasons behind them, not a promise to “optimize next month.”

9. Set the offer and the margin the account has to protect

Here is where I stop handing over decisions. I worked on a SaaS account that changed its offer every quarter: same clicks, different trial length, onboarding fee, and close rate. CPA stayed flat while pipeline fell in half. The ad account could report the CPA. It could not decide whether that CPA still made business sense.

Say you spend $20k a month, close 10% of demos, and keep $6,000 in margin per customer. That puts a $600 margin ceiling on what you can pay per demo. Whether you should spend all the way to that ceiling depends on capacity, cash, and how much chaos sales can absorb. The ceiling comes from the business, not the bidding interface. An engine needs that constraint before it starts chasing more demos.

Verdict: keep it human. First step: write down the offer, your maximum acceptable CPA, and your break-even ROAS before handing over bids or budgets. Make the strategist hold that line.

10. Tell the engine when the business changes

That quarterly-pivot SaaS account also taught me the failure mode no demo covers. We changed pricing on a Tuesday. Ads kept selling the old promise until the following Monday, when I finally rewrote everything. Faster copy production would have helped only if the system had known about the change.

An autonomous setup can rebuild ads, pages, and guardrails faster than I could do it by hand. It cannot announce a pricing change it was never told about. The same practitioner who warned about confident agents notes that agents can retain corrections rather than merely follow fixed scripts (his discussion). Give groas that context through the guardrails call and private Slack channel, then check the logged actions. The rebuild can be automated. The alert is yours.

Verdict: keep the business-change decision human; hand over the rebuild. First step: when the offer, price, or service area changes, tell your strategist that day and confirm which live ads and pages need attention. For the wider boundary, see what genuinely runs unattended.

11. Decide what counts as a conversion

This is the job I would start with. I have seen audits where the real problem was tracking, not tactics. Set every form fill as a Primary conversion and Smart Bidding will pursue form fills, including spam and job seekers. The system is doing what you told it to do. That is precisely the problem.

Primary conversions feed Smart Bidding and the Conversions column; Secondary conversions remain available for observation in All conversions (the tracking breakdown). An engine can optimize against that setup, but it cannot decide for your business whether a call was qualified or a demo became pipeline. You have to define success, connect it to the account, and check that the signal still means what you think it means.

Verdict: keep it human. First step: choose a Primary conversion tied to money, decide what belongs in Secondary, and check the setup before changing bids. What an AI agent runs versus what stays yours is worth reading after that decision, not instead of it. I would hand over the other eight operational jobs today. I would start here, because automating the wrong goal only gets you to the wrong result faster.
