Should a marketing agency create Google Ads inside the client's own account?

Yes, that is usually the cleanest arrangement because campaign history, conversion data and ownership stay with the business.

The short answer in context

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. The commercial relationship matters as much as the tactic. Ownership, accountability, access to data and a clear definition of success prevent many of the problems businesses experience with marketing suppliers.

Follow the money from search term to customer

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. A useful Google Ads audit follows the complete chain: the exact search term, keyword, advert, landing page, conversion and final sales outcome. If the account stops at ‘conversion’, you can easily optimise for the wrong thing. A form submission from outside the service area, a two-second accidental call and a genuine £5,000 customer should not all carry the same value. The closer the data gets to real customers and gross profit, the better the bidding and budget decisions become.

Search terms matter more than the keyword list

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. Advertisers often look at the keywords they chose and assume that is what they paid for. The search terms report shows what users actually typed. Broad or automated matching can reach searches with very different intent, so irrelevant terms need to be excluded and valuable patterns need to be separated into clearer ad groups or campaigns. This is one of the fastest ways to improve a local service account without simply raising bids.

Ownership should be separated from management

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. An agency may manage the website, Google Ads, analytics or hosting, but the client should know who legally and technically controls each asset. The business should normally retain owner-level access to the domain, analytics, Search Console, advertising accounts and Google Business Profile. That avoids a common nightmare where changing supplier means losing years of data or being locked out of the company’s own domain.

Ask for decisions, not just activity

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. ‘We wrote four pages’ is an activity report. ‘We wrote these four pages because Search Console showed demand, the current site had no relevant landing pages and those services have high margin’ demonstrates strategy. A competent provider should be able to explain why the work exists, what result it is intended to influence and how that result will be measured.

Use a decision framework rather than a yes-or-no rule

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. Define the upside, downside, cost of being wrong, reversibility of the decision and evidence already available. A tactic may be sensible for a high-margin business with spare capacity and completely wrong for a low-margin business that cannot handle more leads. The answer becomes much clearer when the decision is tied to the actual operating model.

A practical process

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. A good way to handle this is to work through the issue in a fixed order rather than changing several things at once. That makes it easier to identify what actually caused the improvement or decline.

• Keep owner-level access to domains, analytics and advertising accounts.
• Ask what will be done in the first 30, 60 and 90 days.
• Define a qualified lead before judging performance.
• Understand contract notice periods and ownership clauses.
• Ask how content, links and technical work are produced.
• Require reports to connect activity with commercial outcomes.

Common mistakes

• Letting a supplier be the only owner of critical accounts.
• Accepting guaranteed ranking claims.
• Reading reports full of activity but no commercial outcomes.
• Signing contracts without understanding the exit process.

Important exceptions and edge cases

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. There are usually valid exceptions. A tactic that is sensible for a high-margin business with spare capacity may be wrong for a low-margin company that is already overloaded. Similarly, a strategy that works in a low-competition town may fail in central Belfast or another dense market. Use the rule as a starting point, then check it against the business model and local competition.

How to measure whether it is working

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. Track completed deliverables, account access, lead quality, acquisition cost and revenue outcomes against the agreed scope. Require explanations for meaningful changes rather than reports that simply list activity.

Local-business perspective

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. For local businesses in Northern Ireland, the same tactic can perform very differently by area. Belfast often has denser competition than smaller towns, while regional work may have higher travel cost and lower search volume.

Worked example

Imagine a local campaign buys 112 relevant clicks at an average of about £3.70 per click, for roughly £414 in media spend. If that produces 10 genuine enquiries, the raw media cost per lead is about £41.40. That number is still not enough to judge the campaign. If only one lead is in the correct area and ready to buy, the effective cost of a qualified lead is much higher. If several become profitable customers, the campaign may be excellent. This illustrates why click cost and even headline cost per lead should never be viewed without lead quality and close rate.

What I would do next

• Export the last 30–90 days of search terms and label them relevant, irrelevant or uncertain.
• Check that only commercially meaningful actions are marked as primary conversions.
• Compare performance by location, device and hour/day before changing bids.
• Send the highest-value intent to a dedicated landing page where possible.
• Record which leads became customers so future optimisation can use sales quality.

Bottom line

When assessing should a marketing agency create Google Ads inside the client's own account, the practical issue is not whether the tactic exists, but whether it fits the business, customer journey and competitive market. The strongest answer is the one that can be tested against real business data. Avoid shortcuts, preserve what already works, and change one major variable at a time where possible. If the activity produces more qualified enquiries at an acceptable acquisition cost, keep improving it. If it produces impressive-looking metrics without useful customers, the strategy needs to change.
