Choosing a marketing agency is a big decision for a small business. This article covers how to figure out what you need, how agencies charge, what to check before you sign, and the red flags to watch for — including newer AI-powered agencies. It’s written for small business owners, founders, and managers who are evaluating agencies for the first time or want a second opinion before switching.
Outsourcing your marketing is often a smart move, especially if you don’t have the time or expertise to run it yourself.
What you need is an agency that delivers results in a way that still leaves you a profit. You need the agency to understand your company, your products, and your services.
You’ll want your agency to adapt as things change, and you want to be able to communicate easily with the people running your account.
An agency has to deliver results that lead to more sales. If you’re getting thousands of clicks a day but no sales, something is wrong. It could be your ad, your sales pitch, click fraud, a mismatch between your offer and your audience, or your price point. You want a company that helps you hit your goal, not one that just shows a lot of activity with no sales to show for it.
Key Points and Facts About Choosing a Marketing Agency
- Agencies typically charge one of four ways: a percentage of your ad spend, a monthly retainer, a flat project fee, or an hourly rate.
- Percentage-of-spend fees generally run 10% to 20% of your monthly ad budget.
- Hourly rates vary widely by seniority, from around $50 an hour for junior staff to $300 or more for senior strategists.
- Watch for exaggerated results, secret formulas, guaranteed rankings, and promises of instant followers or traffic — these are common red flags.
- AI-powered agencies are now common and come with their own set of things to check before you sign.
Figuring Out What You Want
Define Your Goals
It’s essential that you understand your own needs and goals. Don’t depend on the marketing company to tell you what you need.
They may try to sell you something you can’t afford, or a strategy that doesn’t match your goals. Know what you want first, then listen to their ideas.
Will You Focus On Brand Marketing?
Brand marketing builds awareness of your product over time. It takes longer to see results and costs more, because building awareness means repeating your message until it sticks.
TV and radio commercials that run repeatedly are a classic example. Magazine ads and billboards work the same way.
Will You Focus On Direct Response Marketing?
Direct response marketing is trackable, because the prospect responds directly to the ad. Flyers, direct mail, Facebook ads, Google ads, banner ads, and infomercials are all examples.
Define The Service You Want
What matters most to you in a marketing agency? Do you want regular reports? A dedicated account rep? Fast campaign turnaround? A steady posting schedule?
Define what you need before you start searching for a company.
Details To Look Into
Contracts And Cancellations
What is the cancellation process? Are there fees if you cancel? Do you keep the ad and campaign designs, or does the agency own them?
How Do You Pay For Services?
Fees Based On A Percentage Of The Media Spend?
Most agencies that charge based on ad spend fall between 10% and 20% of your monthly budget, according to 2026 industry pricing data. If you spend $10,000 on a campaign, expect to pay roughly $1,000 to $2,000 in agency fees, sometimes more at lower spend levels and less at higher ones.
Monthly Fee?
Monthly fees are common for social media and online campaigns. The agency sets up the campaign, then maintains it.
Many agencies offer packages of different sizes, so you can start small and test results. Once you see results, you can move up to a bigger package.
Flat Fee?
Some agencies charge a flat fee covering setup, ad creation, artwork, and placement.
Hourly Fee?
Hourly rates vary a lot depending on who’s doing the work. Junior staff often bill $50 to $100 an hour, mid-level specialists $100 to $175, and senior strategists $175 to $300 or more, according to 2026 agency pricing data. Many small business agencies land around $100 to $150 an hour on average.
Checking Out A Company
Check Their Portfolio
Check the company’s portfolio to see the style, quality, and type of clients they work with.
How Does The Company Promote Themselves?
Look at how the agency handles its own marketing. Does it meet your standards? Is this the kind of representation you want for your business?
Find out how long the agency’s clients typically stay. A high retention rate suggests satisfied clients. A low one suggests clients try the agency out but don’t get results.
Contact Previous Clients
Try to contact past clients to hear about their experience. Consider asking:
- What did you like about the company?
- How long did you work with them?
- What were the challenges of working with this company?
- Were there any hidden costs?
- Did you have a dedicated account representative?
- Did you get the results you expected?
- Is there any advice you’d give me about working with this company?
What To Watch Out For When Choosing A Marketing Agency
Exaggerated Results
Watch out for agencies that make claims that seem too good to be true. Imagine an agency tells you: “We increased sales for one client by 12,000 percent in two weeks.”
Here’s the math behind a claim like that. Before the agency stepped in, the client had one sale. The agency ran a $3,500 Google Ads campaign over two weeks and generated 120 sales — a 12,000% increase from a baseline of one.
Is that technically true? Yes. Was it profitable? At 50 cents per click, $3,500 buys about 7,000 clicks. That’s 120 sales out of roughly 7,000 clicks, or about 1.7%.
That’s not necessarily bad, but it’s not the eye-popping result the “12,000%” headline suggests either. It’s worth noting that even well-run campaigns lose some clicks to invalid traffic — as of 2026, Google Ads sees an average invalid click rate of around 11.5% — so a rough patch in performance isn’t automatically the agency’s fault. Look at the real numbers, not the headline percentage.
Secret Formulas
If an agency is offering a “secret formula,” look elsewhere.
Ask yourself: if someone had a secret formula to get swarms of people buying products, would they sell that secret for a few thousand dollars? Or would they keep it and make ten times as much themselves?
If you’re after search engine marketing, you need links from authority sites, good content, solid on-page optimization, and a clear picture of who you’re competing against.
Don’t fall for a guaranteed first-page ranking on Google. It could happen if you’re targeting a long-tail keyword with no competition, but treat any promise of a guaranteed position as a red flag — credible agencies report directional, dated results with clear caveats, not guaranteed rankings, according to current industry vetting guidance. Ask the agency what they’d say about ranking for a highly competitive keyword like “Real Estate,” and see how they respond.
Guaranteed Results
In marketing, there are no guarantees on results. Any agency promising guaranteed results is a red flag.
The only credible guarantee an agency can offer is the number of ads they’ll run, where those ads appear, and the work they’ll do. Beyond that, forget about guaranteed results.
Offering A Flood Of Traffic Or Thousands Of Likes And Followers Within A Few Days
Promises of thousands of new visitors, likes, or followers appearing within days are a red flag.
Don’t fall for promises of thousands of new people suddenly swarming your business, website, or social media page. That kind of spike in a short period usually means fake accounts and automated bots.
Vetting AI-Powered Marketing Agencies
More agencies now describe themselves as AI-powered or AI-driven. Before hiring one, ask exactly what’s automated and what’s done by a person, and expect a straight answer.
Red flags include an agency that can’t name the actual tools it uses, gives you one vague flat quote with no breakdown, wants to own your ad accounts, has no accountable person assigned to your account, or shows you screenshots instead of tracked, verifiable results. A long-term contract demanded before you see any measurable results is also worth a hard pause.

FAQ: Choosing a Marketing Agency
How much does a marketing agency typically charge?
- It depends on the pricing model. Percentage-of-spend fees usually run 10% to 20% of ad spend, while hourly rates range from about $50 to $300+ depending on the specialist’s experience.
What’s the difference between brand marketing and direct response marketing?
- Brand marketing builds long-term awareness through repetition and takes longer to show results. Direct response marketing asks for an immediate, trackable action, like a click or a call.
Is a guaranteed first-page Google ranking a red flag?
- Usually, yes. Rankings depend on too many variables for any agency to guarantee, and credible agencies describe results as directional rather than guaranteed.
What should I ask a marketing agency’s past clients?
- Ask about hidden costs, communication quality, whether they had a dedicated account representative, and whether the agency delivered the results it promised.
What’s different about vetting an AI-powered marketing agency?
- Ask what percentage of the work is automated versus human-reviewed, which specific tools the agency uses, and who is accountable for your results. Vague answers or an unwillingness to share this information is a red flag.
