The choice between an independent Google Ads specialist and an agency isn’t about skill, it’s about continuity and coverage: an independent specialist usually costs less and knows your account better, while an agency usually covers vacations, illness, and the areas that paid search alone can’t fix, like tracking and landing pages.
What an independent specialist does better
A good independent specialist has two advantages that are hard to replicate. They handle few accounts, so they know yours in depth, and you talk directly to the person doing the work, with no account manager layer in between.
The cost is also lower, since there’s no structure to maintain. For a company with one product line and one main campaign, this is usually enough.
Where an independent specialist falls short
The problem is rarely technical. It’s about coverage.
Google Ads management isn’t an isolated discipline. A campaign that isn’t converting could be losing out on the landing page, due to poorly set up tracking, the offer, or a sales team that never calls back. An independent specialist can often see the problem but can’t fix it, because the fix is outside of Google Ads.
There’s also a continuity risk. A person gets sick, travels, or takes on a bigger client. Meanwhile, your account keeps spending every day.
- Who manages the account if they’re out for two weeks
- Who adjusts the page when conversions drop
- Who sets up GA4 if tracking breaks
- Who responds to Google if the account gets suspended
What an agency delivers beyond the campaign
An agency solves the same problem with more hands on deck. The real gain isn’t having several people, it’s having several skill sets under the same contract.
When the campaign is performing well but sales aren’t coming in, someone needs to look at the page, the form, the tracking, and the funnel. If that’s all under the same contract, the fix happens in days. If it’s split across three vendors, each one points to the other and the month goes by.
This is the setup our Google Ads management follows, with conversion tracking and page analysis included in the same scope.
Where agencies fall short
It’s worth saying the other side too. A bad agency delivers a pretty report and a stagnant account. You talk to an account manager who passes your request along, it goes into a queue, and the account that needed an adjustment on Tuesday gets touched on Friday.
The warning sign is simple. If you don’t meet the person who’s actually going to run your account during the sales meeting, you’ll probably take a while to meet them afterward.
The cost nobody puts in the spreadsheet
Comparing an independent specialist’s fee with an agency’s fee is only looking at half the equation. The other half is your time.
With an independent specialist, someone at your company has to be the bridge with the website developer, whoever manages the CRM, and whoever handles the lead. That someone is usually you. If your time is worth anything, add that to the fee before concluding it was cheaper.
With an agency, that coordination is part of the contract. The risk shifts: you might not know who, inside the agency, is actually handling your account today.
The three most common scenarios
Local service business, one campaign, budget under R$2,000 a month. A competent independent specialist can handle this, and an agency tends to be too expensive for the size of the problem.
Business with multiple product lines or multiple cities. This brings multiple campaigns, separate budgets, and reporting by line. This is where one person alone starts to become a bottleneck.
Anyone already running ads who doesn’t know how much they’ve sold. That’s not a campaign problem, it’s a tracking problem. It requires someone who can work with GA4, GTM, and the website, and that’s rarely the same person managing bids.
How to test before deciding
You can’t know for sure without putting someone to work, but you can reduce the risk.
Ask for a diagnosis of your current account before signing any monthly contract. What comes back reveals more than any meeting. Whoever opened the dashboard will cite your search terms and your numbers. Whoever didn’t will write something that could apply to any company.
And agree on a review timeline. Switching providers every 45 days prevents the algorithm from learning anything and guarantees neither approach will work.
The question that decides it
Don’t ask which one is better. Ask which problem you’re closest to.
If your campaign is simple, your budget is small, and your site already converts, a good freelancer gets the job done for less. If you’ve been running ads for months, spending money, and can’t say how many sales came from Google, your problem isn’t campaign management, it’s measurement, and that takes more than one skill set.
The most honest test is to ask whoever you’re considering for the search terms report from the last 30 days and the list of configured conversions. Anyone who can’t deliver both won’t improve what you already have.
