Google Ads: Do It Yourself or Hire an Agency? An Honest Guide to Deciding

Three routes compared

The question "yourself or an agency" now has a third answer: a tool that checks your account and suggests changes that you approve. None of the three routes is always right. What matters is how much time, knowledge and budget you have and how much control you want to keep.

The most important criterion is not in the table but behind it: who owns the account, and who sees the data? We cover that in the section on the contract.

When you should do it yourself

Doing it yourself works if three conditions are met.

1. You have time on a regular basis. As a rough rule of thumb for a manageable account, allow two to three hours a week. This is not a study or a measurement, just a guide; an account with many campaigns needs more.
2. You can check the tracking. Without reliable conversion data, every decision about bids and budget is made blind. How to do it is explained in the article Setting up and checking conversion tracking in Google Ads.
3. A flat fee would be out of proportion. If an agency fee would make up a large part of your ad budget, too little is left for the actual clicks. What clicks, budget and management cost is set out in the article Google Ads cost 2026.

The four things you then really have to do

If you manage the account yourself, you do not need to master everything, but you do need to carry out these four tasks regularly:

The search terms report is your most important tool here. Google describes it like this: "Use the search terms report to know how your ads performed when triggered by actual searches", and by adding irrelevant search terms as negative keywords, you can prevent your ad "from showing to people who are looking for something you don't sell" (Source: Google Ads Help, About the search terms report, accessed 30 October 2026).

You will find a complete order of checks in the Google Ads audit checklist.

When an agency is the right fit

An agency pays off if you lack time or expertise and your budget can carry the fee. Published prices are rare. One example from a single source, not a market average: Ostend Digital states "typical agency costs for SMEs: 800 to 3,000 EUR/month (excluding media budget)" (Source: Ostend Digital, Google Ads Agentur beauftragen (German), accessed 30 October 2026). The ad budget comes on top. Other agencies charge a share of the budget or by the hour. So always compare fee plus budget.

How to recognise a good agency: ten questions

Ask these questions in the first meeting. A good agency answers them without evasion.

1. Will the Google Ads account be set up in my name, and will I remain an admin?
2. What access level will the agency get, and why exactly that one?
3. How do you check before the start that the conversion tracking is correct?
4. Which metric is the goal: enquiries, revenue, cost per enquiry?
5. How often will I see a report, and what will it contain?
6. Which changes will you agree with me beforehand, and which will you make on your own?
7. Who exactly will manage my account, and how many hours per month are included?
8. How do you deal with search terms that do not match my offer?
9. What happens to the account, data and conversion history if I cancel?
10. How long is the notice period, and is there a minimum term?

What the contract must cover

Three points decide whether you can later switch agency without damage.

Account ownership. An agency usually works through a manager account (MCC). Google points out that a manager account "can also be given ownership of a client account". At the same time, "users with administrative access to those accounts can terminate the relationship with the manager account at any time by unlinking their account from the manager account" (Source: Google Ads Help, Manager Accounts (MCC), accessed 30 October 2026). So put in writing that the account is in your name and that you keep admin access.

Access level. Google has five access levels (Source: Google Ads Help, About access levels in your Google Ads account, accessed 30 October 2026):

For ongoing management, Standard is sufficient in many cases. You should keep Admin yourself. More on this in the article Granting Google Ads access safely.

Cancellation and handover. Specify that the account, campaigns and conversion history stay with you and that the agency gives up its access at the end of the contract. How a switch works in practice is described in the article Switching your Google Ads agency.

The third route: a tool with approval

Between "everything yourself" and "hand everything over" there is a model in which a tool does the data work and you make the decisions. The tool reads your account, finds anomalies and drafts specific changes. Nothing is carried out until you approve it.

What a tool can take over

• Checking: reviewing tracking, search terms, budgets, locations and ad schedules regularly, without you having to open every table yourself.
• Prioritising: sorting findings by urgency so that you start with what matters most.
• Suggesting: drafting a specific change, for example a list of negative keywords that you review before it is carried out.
• Enforcing limits: applying fixed caps on bids and budgets, so that even a wrong suggestion cannot do much damage.

What a tool cannot do

• Strategy: You decide which audience you address and which offer you put first.
• Offer: A tool does not make an unsuitable offer more attractive.
• Website: A slow or unclear landing page remains a problem that is solved outside Google Ads.

If you work with approvals, you should also organise the principle properly within your team. The article The four-eyes principle in Google Ads shows what that looks like. If you use AI assistants, the article Connecting Google Ads to Claude or ChatGPT explains how reading and writing are kept separate there.

Decision tree

Go through the questions in order. The first answer that fits is your recommendation.

1. Is your conversion tracking demonstrably working? If not: fix it first, whichever route you choose. Without tracking, none of the three routes can be judged fairly.
2. Do you have fixed time for the account every week? If not: an agency or a tool.
3. Do you understand search terms, keyword match types and bids? If not, and you do not want to learn: an agency. If you want to learn: a tool with approval that explains its suggestions to you.
4. Can your budget carry an agency fee without leaving too little for clicks? If not: do it yourself or use a tool.
5. Do you want to decide on every change yourself? If yes: do it yourself or use a tool with approval. If you would rather hand over: an agency, with a clear contract on account ownership and access.
6. Do you need help with strategy, your offer or your website? If yes: an agency with the corresponding scope of services is more likely to cover this than a tool.

Key takeaways

• Control over the account and data is the most important criterion. The account belongs to you, and you remain the admin.
• Always compare costs as the sum of the fee or tool price plus the ad budget.
• Tracking first: without reliable conversions, every assessment of the management is guesswork.
• No route is always right. You can switch when your time, budget or knowledge changes.
