Your Google Ads Agency vs a Meta-Dedicated Service: Who Should Run Your Facebook Ads?

Your Google Ads agency will probably say yes to running your Meta ads before you finish asking. For a small business already paying that agency for search, the choice is the familiar Google agency running Meta on the side or a service dedicated to Facebook and Instagram ads. The familiar option looks easier. It is often the wrong hire.

Search rewards keyword, bid and budget work against demand that already exists. Meta depends much more on the ads you put in front of people and how quickly you learn which ones work. I spent the better part of a decade managing Google Ads accounts. Some habits from that work carry over: clean conversion data, budget discipline, and an unwillingness to celebrate clicks that do not become customers. Others quietly burn money on Meta while the dashboard looks busy.

I would compare these two options on five things: creative production, testing, tracking, reporting and the full contract price. Then I would pick a winner for each kind of business. No consolation trophy for the agency with the nicest slide deck.

First, understand why search habits fail on Meta

On search, you choose which queries to show up for and what they are worth. The ad needs to answer demand the person has already expressed. On Meta, there is no search query to intercept. Targeting is largely automated, so the assets you supply and the response they earn carry much more of the work. Creative is not decoration on top of the media plan. It is a major lever in the plan.

That changes the staffing question. A search account can run on a relatively small set of ad variants refreshed when performance calls for it. On Meta, you need fresh concepts before existing winners wear out. In an r/PPC discussion about staffing both channels, commenters recommended separate specialists rather than assuming one PPC hire would approach both the same way.

The most expensive carryover habit is assuming that putting new ads into an ad set means you have tested them. Meta may send most of that ad set’s budget to an established winner, leaving the new work too little delivery to teach you much. Advertisers describe this problem often. A manager can then report that the new ads lost. They may never have had a fair run.

1. Creative output: who makes the next ad?

Ask both candidates: How many new ads enter my account each month, and who produces them? Do not accept “we handle strategy” as an answer to a production question. If the agency expects you to provide every video, image and line of copy, say so in the plan. If the dedicated service produces them, ask what it needs from you and when.

The workload is different from a quarterly search-ad refresh. Biddyco tracked the top 50 ads across 10 large US accounts with $22 million in combined spend and found that most top ads were replaced within two months. Its working rule is to introduce new ads every 2–4 weeks and keep roughly one live creative per $1,000 of weekly spend. At $20,000 a month on Meta, that rule points to roughly five live creatives at a time. It does not mean you must produce five new ones every week.

Production targets also depend on spend and the account’s ability to generate useful results. Creative-volume benchmarks by spend tier offer starting points, not a universal quota. The question is whether your provider has a repeatable way to make, launch and replace ads at a pace your account can support. A dedicated Meta service should be able to show you that process. A Google agency adding Meta to an existing retainer may have a designer’s spare hours instead.

This is the first practical filter: if nobody owns production, nobody owns Meta performance.

2. Testing: did the new ad get a real chance?

Producing ads is only half the job. The account has to test them in a way that answers a question. Search managers optimise campaigns; strong Meta operators design tests. They decide what is changing, what stays constant, and whether the available conversions can support the experiment.

Say you have hooks, formats and angles to try. A creative-testing matrix can turn those possibilities into a sequence rather than launching every combination at once. Change a hook and a format together, and a winning ad does not tell you which change helped. Launch too many variants, and each gets too little data. One testing framework points out the mismatch between a 36-asset test and an account generating only 20 conversions a month.

I have seen the search-trained version: put three variants together, “let the algorithm decide,” and check back in a fortnight. The problem is not that automation made a decision. It is that the incumbent may receive most of the spend before the newcomers can prove anything. Buyers sometimes keep the winner running while giving new concepts their own test budget. That is not a rule to apply blindly; it is evidence that delivery structure matters.

Fatigue makes the testing cadence more important. A Meta creative-fatigue benchmark found CTR falling before CPA rose, without fatigue necessarily announcing itself as a CPM spike. Meta also provides a “Creative fatigue” delivery status and recommends a materially different ad when it appears. Watch the response to the creative, not just the auction price.

Ask each provider what happens when a new concept goes up against a current winner. A useful answer describes how the newcomer gets enough delivery to be judged.

3. Tracking: can you trust the conversion count?

Here is where channel experience matters without making the Google agency automatically wrong. Both providers can set up tracking well, and both can get it wrong. But a team taking on Meta as an add-on needs to show that it has checked Meta’s particular failure points, not merely that Google Ads and GA4 are working.

Meta’s Conversions API sends server-side events alongside the browser Pixel. If the same purchase arrives through both, the events need deduplication using event_id and event_name. Miss that step and a reported purchase can be counted twice. The chart improves; revenue does not. One Meta-specialist agency says it regularly inherits accounts with broken or duplicated events. That is its experience, not a reason to assume every transferred account is broken. It is a reason to check yours.

Ask who verifies Pixel and Conversions API events, how they check deduplication, and what happens when platform-reported conversions do not match the business’s view of sales. A nice ROAS number is not an answer if the underlying purchase count is wrong.

4. Reporting: will it tell you what to make next?

A bundled monthly report can give Meta a second tab and call the job done: spend, CPC, CTR, conversions. Those numbers have uses. They do not, on their own, explain which creative idea is carrying the account or what the team plans to replace next.

For Meta, I want to see performance at the creative level: the hooks and angles in play, which ads earn attention, which lead to conversions, which are tiring, and what the next test will change. Hook rate, hold rate and creative-level CPA can help tell that story when the format and data make them useful. The report should connect an observation to the next production decision. Otherwise it is a receipt with charts.

The same standard applies to the dedicated service. A Meta label on the website does not make vague reporting more informative. Ask both teams to walk through what you will learn each month, not just what metrics you will receive. If the answer ends at clicks and leads, you still have to work out what to do next yourself.

5. Cost: read the fee and the creative scope together

The headline management fee is not the full comparison if one provider makes the ads and the other expects you to supply them. Price the work you actually need, including production. Then read how the fee changes as spend grows.

Percentage-of-spend and flat fees separate as budgets rise. At 15%, management costs $450 on $3,000 of monthly spend and $3,750 on $25,000. A $1,500 flat fee stays $1,500 at either level. Those two fees meet at $10,000 a month: below that, the percentage costs less; above it, the flat fee does. Published agency pricing ranges include 10–20% of spend or flat fees of $1,000–$2,500 a month, with more expensive full-service arrangements too. Watch for minimums as well as percentages; one agency owner quotes a $25,000 minimum monthly spend for its Meta service.

This is where groas has a clearer offer than the usual retainer add-on. Its Meta Ads management is $1,499 a month flat, with no percentage of ad spend or setup fee, month-to-month terms, a 7-day money-back guarantee and a named account manager. It works on audiences, budgets and ads continuously, tests new ads and scales winners. You still need to establish who supplies or produces the creative assets your account needs. The fee structure, though, does not rise simply because your media budget does.

Do not buy a cheaper line item that leaves you with an unstaffed creative job. And do not buy a costly production promise without checking what it delivers.

The head-to-head in one table

The table is a shortlist of questions, not a certificate of competence. Hire the team that can show you who makes the ads, how they test them, and what the results change.

Who should still pick the Google agency?

The bundled option wins in two specific situations.

• Meta is a small remarketing supplement. If you spend under about $3,000 a month on Facebook and Instagram, already have search traffic to remarket to, and do not need a steady flow of cold-audience creative, your Google agency may be the practical hire. At low spend, a dedicated retainer can swallow too much of the budget. Even people selling Meta agency services advise smaller advertisers to consider a freelancer or DIY. Check the add-on fee before you call it cheap.
• Creative reliably comes from your team. If a founder or in-house person will produce video and copy on schedule, the outside provider may only need to handle a simple media-buying setup. Settle who makes the Meta ads before signing. “The agency runs it” is not an ownership plan.

In either case, make the Google agency explain its testing and tracking process. Familiarity is a reason to consider it, not a reason to skip those questions.

Who should pick the dedicated service?

Once Meta is an acquisition channel rather than a remarketing supplement, I would pick the dedicated option. Past about $10,000 a month in Meta spend, the need for ongoing creative work becomes hard to treat as a side task. More spend can exhaust a winning ad faster unless production keeps pace; one agency describes fatigue as a systems problem. That is the right frame. You need a process, not a heroic last-minute request for three more videos.

The dedicated service still has to earn the hire. Have it specify creative ownership, testing structure, event checks and reporting. A shop that cannot answer those questions does not become a specialist by putting “Meta” in its name. But a capable dedicated team is built around the work a scaling Meta account keeps demanding. The search agency is usually built around something else.

My verdict by business type

Local service: If Meta spend is under $3,000 a month and mostly remarketing to search visitors, let the Google agency handle it if the add-on is sensible. If you are spending past $10,000 a month to reach cold audiences, choose a dedicated Meta service with a real creative cadence. Judge it on lead quality and booked jobs, not CTR.

Ecommerce: Choose dedicated at serious spend. Creative refresh and feed performance are too important to leave to the search team’s spare capacity. If you want a flat management fee rather than a percentage that rises with spend, groas is $1,499 a month, tests new ads continuously and logs its actions so you can see what changed. Confirm the creative-production arrangement before you start.

B2B or SaaS: Modest Meta spend for awareness in a search-heavy mix can stay with the Google agency. If Meta contributes meaningful pipeline, go dedicated. The partner needs to evaluate creative against qualified opportunities and closed-won revenue, not congratulate itself on form fills.

The bundled option keeps winning because it saves a hiring process. That convenience is real, but it is a one-time saving. An account that cannot produce and test enough creative pays for the gap month after month. Before you sign, ask both contenders three questions: How many new ads will enter my account, who makes them, and how will you know when a winner is exhausted? The wrong hire hesitates on all three.
