Most Google Ads accounts we inherit are not underfunded. They are leaking. The budget is adequate, the intent is there, and a meaningful share of the spend is going to searches that were never going to become customers.
That is good news, because waste is fixable and usually fixable quickly. This is what we look at first, in the order we look at it, and why experienced management tends to pay for itself before it costs anything.
Start with what you are measuring
Before touching a bid or a keyword, check that conversion tracking is telling the truth. If Google is optimising towards the wrong action, or counting one enquiry three times, every decision after that inherits the error.
The test is simple and almost nobody does it: compare the conversions reported in Google Ads against the enquiries you genuinely received in the same period. If the two do not reconcile, stop and fix that first.
An account optimised against bad data will look like it is improving while quietly getting worse. Tracking is not admin. It is the foundation everything else stands on.
Where the budget usually goes
- Searches you never wanted. Without a maintained negative keyword list you pay for "free", "jobs", "salary", "DIY" and every competitor's brand name. This is the single most common source of waste we find.
- Broad match running ahead of the data. Broad match is a reasonable tool once the account has conversion history to learn from. Before that, it spends your budget exploring.
- Traffic landing on the wrong page. Someone searching for one specific service should land on that service, not on a homepage that makes them hunt.
- Campaigns nobody has opened since launch. Auctions shift, competitors change their bids, and an account that was efficient a year ago rarely still is.
- Bidding towards the wrong outcome. Optimising for form fills gets you form fills, including the ones that never answer the phone. Optimise towards what actually becomes revenue.
What lowering cost per acquisition actually looks like
Cost per acquisition is the number worth managing, because it is the one that decides whether the account makes money. It comes down in four ways, and they compound.
| Lever | What changes | How quickly |
|---|---|---|
| Cut wasted spend | Negatives, placement exclusions, dayparting | Immediate |
| Improve relevance | Tighter ad groups lift quality score, which lowers what you pay per click | Weeks |
| Improve the landing page | More of the same traffic converts, so the cost per acquisition falls without spending less | Weeks |
| Feed better data to the bidding | Accurate conversion values let automated bidding chase profit rather than volume | 2 to 3 months |
None of these require a bigger budget. Three of the four require nothing but attention.
Why experience matters more than tooling here
Google Ads is not short of automation, and the automation is genuinely good. What it cannot do is decide what a customer is worth to you, judge whether a campaign type suits your business, or tell you honestly that your offer is the problem rather than your bidding.
That judgement is what you are buying. We have been at this for over 14 years and we are an accredited Google Partner, which means the best-practice framework is not something we are working out on your account. It is applied from day one, and the platform decisions are made by someone who has seen the same mistake in a hundred other accounts.
The production work runs on AI: search-term mining, reporting, first drafts of ad copy, anomaly detection. The strategy, the budget calls and the accountability stay with a person you can ring.
You should be able to ask your account manager why a campaign was paused and get a straight answer the same day. If that is not happening, the fee is buying you something other than management.
What good management should give you
- Conversion tracking you have personally verified against real enquiries
- A maintained negative keyword list, updated weekly rather than quarterly
- Reporting that leads with cost per acquisition, not impressions
- Ownership of your own Google Ads account, so your performance history stays yours
- A named person accountable for the result, and no lock-in keeping you there
What it costs to have someone run it
In our experience management fees commonly run $300 to $800 a month for a small single-campaign account and $500 to $2,000 a month for a larger one, separate from your ad spend. Our pricing is competitive because delivery is AI-enabled, and what that frees up goes into your media budget rather than our overhead.
Results on this model include SatPhoneShop at a 15% increase in conversions and 10x ROAS, Six Barrel Soda at 25% and 6x, and Rush at 18% and 5x.
Results shown are actual outcomes achieved for the named clients. Individual results vary with market, budget and starting position, and past performance is not a guarantee of future results.

Frequently asked questions
How do I lower my cost per acquisition in Google Ads?
Cut wasted spend first, because it is the fastest win: add negative keywords, exclude poor placements, and stop bidding at times that never convert. Then improve relevance through tighter ad groups, which lifts quality score and lowers what you pay per click. Landing page improvements come next, since converting more of the same traffic lowers cost per acquisition without reducing spend at all.
Why are my Google Ads getting clicks but no conversions?
Usually one of four things: conversion tracking is broken or counting the wrong action, traffic is landing on a homepage rather than the relevant service page, negative keywords are missing so you are paying for the wrong searches, or the offer is not competitive. Check tracking first, because every other diagnosis depends on it being right.
Is it worth paying someone to manage Google Ads?
It depends on the size of your account, not on your feelings about agencies. The management fee is usually smaller than the waste an unattended account generates through missing negatives, untracked conversions and bids set by guesswork. If your account is simple and you have the time to learn it properly, self-managing is genuinely viable.
How long before changes to my account show results?
Cutting waste shows up within days. Relevance and quality score improvements take a few weeks. Anything that depends on automated bidding relearning needs roughly 2 to 3 months, and restructuring during that window restarts the clock. Patience is genuinely part of the method here.
Do I keep my Google Ads account if I change agencies?
You should, and it is worth confirming in writing before you sign anything. The account, its campaign history and its conversion data are yours, with the agency accessing them as a manager. If an account is created inside an agency's own manager account, leaving can cost you the entire performance history.
