Search for the best digital marketing agency and you get three kinds of answer: ranked lists, directories full of star ratings, and agencies describing themselves as the best. None of them has seen your numbers. The agency that suits a bakery running Facebook ads is rarely the one that suits a software company chasing search traffic.
So treat "best" as a test you set, not a title someone else hands out. Here's what the test should include, how to read the lists, and checks you can run on any shortlist in an afternoon.
- Best means best for you. Fit with your channel, customers and budget comes first, then who actually does the work.
- Judge on revenue. The right agency reports cost per customer and revenue, not reach and clicks.
- Own everything. Ad accounts, tracking, your website and your data should sit in your name, with an exit you can use.
- Lists are a starting pool. On Clutch's directory pages, sponsors are listed above non-sponsors, so the top of a page can be bought.
What "best" should mean for a small business
It's tempting to compare agencies on price and portfolio. Neither tells you whether your account will be run well next month. These six tests do, in the order we'd weigh them.
| Test | A good agency shows you | Worth a second look |
|---|---|---|
| Fit | Clients like you, and which channel should carry your growth | Every service for every industry, or a minimum budget above yours |
| Who does the work | The named person running your account, and how many others they handle | A senior person on the sales call, then nobody you've met |
| Reporting on revenue | Spend, leads, customers and the cost of each | Reach, impressions and clicks as the headline |
| Ownership | Ad accounts, tracking, analytics and website in your name | Accounts built inside the agency's own business portfolio |
| Contract terms | Month-to-month or short notice, with a written handover | Long minimums, automatic renewal, creative you can't keep |
| Pricing model | A predictable fee for an agreed scope, ad spend on your own card | A fee that rises with your budget whether or not results do |
Fit comes first because everything else depends on it. An agency that's excellent at SEO for software companies can be the wrong choice for a dental practice that needs booked appointments from Facebook ads this quarter. Ask which channel they'd start with for you, and why.
Who does the work is easy to miss on a sales call. At some agencies the person who sells the work never touches your account. If you're also weighing a solo specialist, agency vs freelancer vs in-house sets out the trade-offs. Reporting, ownership and price have guides of their own: what a report should lead with, what you should own, and how fees are built.
The best agency for which business?
The same agency can be a strong choice for one business and a poor one for the next. What to weigh depends on what you sell and how a sale happens.
| Your business | Weigh most heavily | Ask specifically |
|---|---|---|
| Local service | Booked jobs, calls and fast lead follow-up | How will you count a booking, not just a form fill? |
| Online store | Purchase tracking, creative testing, profit after ad spend | What return on ad spend do I need to break even? |
| B2B or high-ticket | Lead quality and tracking through a long sales cycle | How will you know which leads became revenue? |
| Coach or consultant | Booked calls and a funnel that qualifies first | What happens between the ad and the call? |
| Healthcare | Health ad policies and patient privacy in tracking | How do you set up tracking for regulated clients? |
| Early-stage startup | Testing message and channel before scaling | What will we know after 90 days? |
How to read "best agency" lists and directories
Every ranking you meet can help you build a shortlist. None of them is neutral by default.
Listicles. An article titled "the 10 best digital marketing agencies" was published by someone. Check whether the publisher appears in its own list, and whether the agencies listed paid to be there. In the US, the FTC's rule on consumer reviews and testimonials, in force since 21 October 2024, bars a business from misrepresenting that a website it controls gives independent reviews or opinions about a category that includes its own services. An agency can publish a list. It can't present a list it controls as independent.
Directories. Clutch's own help center says sponsors appear above non-sponsors on its directory pages, though sponsorship doesn't change its rankings or Leaders Matrix, and the highest-tier sponsors appear first. So the first names on a directory page may have paid most, not rated highest. Look for the sponsor marker and read the agencies further down too.
Reviews. Fake reviews are now illegal in the US and the UK. The same FTC rule bans fake reviews and paying for reviews that must be positive. In the UK, the Digital Markets, Competition and Consumers Act 2024 made fake reviews and reviews with hidden incentives a banned practice, with guidance from the Competition and Markets Authority since April 2025. Genuine still doesn't mean useful: look for reviews that name the service, the period and the result, and read the three-star ones.
Badges. A Google Partner badge is earned, but read what it measures. Google's requirements are a 70% optimization score, $10,000 of ad spend over 90 days across the accounts an agency manages, and at least half its account strategists certified in Google Ads. Optimization score is an estimate of how well an account is set up, and Google notes that an account can reach 100% by applying or dismissing all of its recommendations. The badge shows an agency runs real spend through Google's process, not what it achieved for a business like yours.
Agencies calling themselves the best. The UK advertising regulator's advice is that a "best" claim people read as measurable is an objective claim that needs evidence, usually about competitors, and that awards alone won't support it. So ask: best at what, measured how, against whom? A vague answer tells you how other numbers may be treated too.
AI assistants. Ask ChatGPT, Gemini or Perplexity for the best agency and the answer usually draws on pages like these. Open the sources it cites and put the same questions to each.
Checks you can run yourself
These eight checks take an afternoon across three or four agencies, and most need nothing more than an email. For the questions to put on the sales call itself, see 12 questions to ask before you hire a Facebook ads agency.
Ask for a sample report
Ask for a recent monthly report from a client like you, name removed. If customers, revenue and the cost of each appear nowhere in it, that's the report you'll get too.
Get the ownership answer in writing
Ask whose business portfolio the ad account, Pixel and audiences will sit in, and whose login owns Google Ads, Analytics, the domain and the website. The answer you want is "yours". Our Facebook ads audit checklist shows where to confirm it.
Read the exit clause before the price
Find the minimum term, the notice period, any automatic renewal, and who keeps the ads, landing pages and creative files when you leave.
Look up the person, not the brand
Get the name of whoever will run your account and look them up. How long have they done this work, and how many other accounts sit alongside yours?
Read one case study for context
A result needs its context: the type of business, the period, the spend and the starting point. A "3x return" with no before and no timeframe can't be judged.
Look at work that's live
If an agency names clients, look at their ads. Google's Ads Transparency Center searches an advertiser's ads by name or website, and Meta's Ad Library covers Facebook and Instagram. You'll see whether the work is current.
Ask who they turn away
A good agency can name the businesses it isn't right for. If every business is a fit, nobody has thought hard about yours.
Price the whole bill
Add the fee, ad spend, creative, tools and setup costs, and set the total against what a new customer is worth to you. Our breakdown of agency costs lists what usually sits outside the quote.
Where NCMborz fits, and where it doesn't
A guide like this would be worth little if it ended by calling us the best. Here's how we'd score on the tests above instead.
- Who we suit: US and UK small businesses that want Facebook and Instagram ads to bring in leads, bookings or sales, often alongside Google Ads, SEO or a new website.
- Who does the work: the person who sells you the work is the person who runs it.
- Ownership: you keep full ownership of your ad accounts, and ad spend goes straight to the platform on your own card.
- Terms and price: month-to-month. Ads management and SEO run $500-$2,000 a month; website and landing page builds are fixed-price, mostly $1,200-$15,000. Details are on our pricing page.
Our published proof is narrow, and we'd rather say so. Two case studies are Meta ads accounts for climbing gyms that sell bookings online. On the first, cost per booking fell from £28.82 to £5.13 on essentially the same budget once purchase tracking and a sales objective replaced a link click objective, and over ten months the account returned 2.95x. The second came from another agency with a sales campaign returning £0.82 for every £1 spent; eight months after the handover the account returns £2.99 for every £1. The third is a coach's funnel build. All three are on our case studies page.
- You want the lowest monthly fee you can find.
- Your offer hasn't sold without ads yet. Ads put a working offer in front of more people; they rarely fix one that doesn't work.
- You can't set aside a real ad budget alongside the fee.
- You want TV, radio, print or PR, or a large team with separate account managers and buyers on every call.
- You need a published case study from your own industry first. We may not have one, and we won't pretend otherwise.
Questions people ask
What is the best digital marketing agency?
There isn't one for every business. The best one for you fits your channel, customers and budget, puts an experienced person on your account, reports on customers and revenue, and leaves you owning your accounts and data.
How do I find the best digital marketing agency for a small business?
Shortlist three or four from referrals, directories and search, then run the same checks on each: a sample report, a written answer on who owns your accounts, the exit terms, the person who would run your account, and the full monthly cost.
Can I trust "best agency" lists and directories?
Use them to find names, not to decide. Check who published a list and whether the publisher appears in it. On Clutch's directory pages, sponsors are listed above non-sponsors, so the first names can be paid positions.
Does a Google Partner badge mean an agency is good?
It means the agency meets Google's thresholds for optimization score, ad spend and certified staff. That shows experience with Google's tools, not results for a business like yours.
Should I hire a specialist or a full-service agency?
A specialist suits you when one channel does most of the work. A full-service agency suits you when the channels depend on each other, like ads sending traffic to a landing page that has to track sales. Either way, one named person should answer for the result.
Is NCMborz the best digital marketing agency?
We don't claim to be. We may suit a US or UK small business that wants Facebook and Instagram ads to bring in customers. We're not the right fit if you want the lowest price, haven't sold your offer without ads yet, or can't commit a real ad budget alongside the fee.
