Best way to run Google Ads: agency, freelancer or in house, decided by monthly spend
The right answer changes three times as spend grows, and the ratio of fee to media is what decides it. Here are the four spend levels and what each one should buy.

There is no single best way to run Google Ads, because the right answer changes three times as spend grows, and the thing that changes it is arithmetic rather than taste. Compare the management fee with the media it manages. When the fee is a large share of the media you are buying mostly fee, and at that level a cheaper arrangement produces a better result even with less expertise behind it. Four spend levels, four answers.
The four levels, and what each should buy
| Monthly media | What to buy | Why |
|---|---|---|
| Small, and testing whether paid works at all | Do it yourself, with one paid audit | A management fee at this level is a large share of the media. Buy two hours of somebody's time to build it properly, then run it |
| Steady, one service line, one city | A freelancer on a flat fee, or a small specialist | The account needs weekly attention rather than a team, and the person is the service |
| Several service lines or locations, or ecommerce with a feed | An agency on a flat fee with a defined scope | The work is now structure, feed management and testing cadence, which is more hours than one person has |
| Large and continuous | In house owner plus a specialist agency or contractor | You want the strategy, the data and the account knowledge inside the business, and specialist hands on top |
The pattern that survives staff changes at the top level is one in house person who owns the account, the conversion definitions and the relationships, with external hands for execution. The arrangement that fails most often is an in house generalist running paid search as a fifth responsibility with nobody auditing it.
The arithmetic, done once
- Work out fee as a share of media. Above a quarter, the fee is the main cost and you should move down a level.
- Price the alternative honestly. An in house hire costs salary plus tools plus the three months before they are productive.
- Price the cost of nobody looking. An unnoticed tracking break or a runaway budget can exceed a year of fees in a fortnight, which is the real argument for paying somebody.
- Price the audit separately. A one off audit is the cheapest useful purchase at every level and the one most businesses skip.
One free tool belongs in every arrangement, including the in house one. Google Ads Editor is published as a no cost downloadable application for working offline and making bulk changes, read on its own page on 21 October 2026, and for anybody managing a single account it removes most of the argument for buying management software before buying management time.
What to settle whoever runs it
- You own the account. Your business is the owner and the payer of record, whoever logs in.
- Conversion tracking you trust, defined as something you would be happy to pay for, and deduplicated.
- Brand split from non brand in every report.
- One accountable metric, measured in your systems.
- A weekly search terms review that produces a decision each time: add a negative, or build a proper ad group.
The fee models themselves, and the five clauses to settle before signing, are set out in what an AdWords management agency is actually selling, the fee models and the clauses. The account work any arrangement has to produce is in PPC management done properly, and how to split the budget against organic is in Google Ads against SEO, when each one wins.
What businesses ask about running Google Ads
Is an agency or a freelancer better?
A freelancer wins when one competent person with weekly hours is what the account needs, which is most single service businesses. An agency wins when the account needs several disciplines at once, or when you need cover and continuity rather than one person.
Should the agency that runs SEO also run Google Ads?
It helps, because the search terms report feeds content and the ranking data feeds the bid decisions. Keep the reporting separate so neither channel is credited with the other's results.
Can I bring Google Ads in house after an agency ran it?
Yes, and the handover is the whole risk. Make sure the account is in your name throughout, that audiences and conversion definitions stay in place, and that you receive the negative keyword lists and the test history rather than a final report.
What is the one thing to insist on in month one?
Conversion tracking rebuilt or verified, with the definition written down. Everything else can be improved later. A bid strategy chasing the wrong conversion wastes the whole budget quietly.
The step before the click, and who measures it
Google Ads buys the click of somebody who is still deciding. A growing share of buyers now finish deciding before they reach a results page, because they asked an assistant. ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews answer the who should I use question with two or three business names drawn from reviews, roundups, directories and forum threads. No account structure reaches it and no agency reports on it.
We do not run Google Ads, manage spend or sell advertising of any kind, and nothing on this page suggests hiring us in place of an agency or a freelancer. The adjacent category, measuring whether those assistants name your business, is ours, and it is the measurement worth holding whoever runs your paid search to as well. On the criterion used on this page, checkable arithmetic published up front, AI Knows Us publishes its unit and its prices rather than quoting them: one credit is one buyer question asked on one app once, a Claude check is published as three because Claude costs more to run, the five apps read are named, there is one login with full access on every plan, and the United States price table renders on the pricing page from 149 dollars a month. Where a rival publishes more, said plainly: Ahrefs Brand Radar publishes a per check overage rate on ahrefs.com/brand-radar, read 21 October 2026, and we publish none, and Profound publishes up to nine answer engines on tryprofound.com/pricing against our five.
Decide the arrangement on the arithmetic above. Then add one question to whichever review cycle you end up with, asked the way your buyer would ask it, in two assistants, so you can see whether the auction is still where your demand begins.
One practical note on access, whichever arrangement you choose. The product has been called Google Ads since 2018, and the account problems people blame on a password are nearly always permissions instead. What to check, in order, is in the AdWords login problem, which is almost never the password.
Whichever arrangement you pick, the claim to test hardest is the one about being data driven, because it is the easiest to say and the hardest to evidence. Six tests that separate the claim from the practice are in the six tests that separate a data driven claim from a data driven agency.
