Hiring a Facebook Ads Agency: What to Expect, What It Costs and How to Pick One That Brings Customers

What you are hiring an agency to do

A Facebook ads agency runs paid campaigns on Facebook, Instagram, Messenger and Meta's partner apps to bring you leads, sales or bookings. Since Meta's Advantage+ campaigns became the default, the platform chooses most of the audience itself. That changes what a good agency does. It no longer wins by finding a clever interest; it wins by producing enough genuinely different ads for the system to work with, by feeding Meta accurate conversion data so it finds buyers rather than browsers, and by improving the offer and the page people land on.

What the service should include

Tracking: pixel and Conversions API with deduplication, the right standard events, and qualified-lead or purchase events sent back from your CRM or store. Creative: a steady flow of new concepts, usually four to six a month, in video for Reels and Stories, square for Feed and static versions, with a testing log of what won and why. Campaign management: structure, budgets, exclusions, placements and the automation settings Meta keeps adding. Lead handling: forms with qualifying questions and fast follow-up through CRM or WhatsApp. Reporting on cost per qualified lead or sale.

What it costs

Agencies charge a flat monthly fee, a percentage of ad spend, or occasionally a fee per result. Creative production is sometimes included and sometimes billed separately, so ask. Our management starts at INR 35,000 per month in India and $500 per month elsewhere, with ad spend paid directly to Meta. On top of the fee, budget enough ad spend for campaigns to exit the learning phase, roughly 50 optimisation events a week per ad set, or start with an earlier event until volume allows. Our guide to what drives Facebook ad costs explains how much is enough.

Creative is where the money is made

Ask any agency you are considering to show you their creative process. Who writes the hooks? Who films or designs? How many concepts per month? How do they decide what to test next? For service businesses, a 30-second video of the owner explaining the offer often beats polished studio work. For e-commerce, product demonstrations, user-generated content and clear offers do the heavy lifting. An agency that produces one new ad a month will watch costs rise as the audience tires of it. See what a Meta Ads expert does.

Questions to ask

Will the ad account and pixel stay in my business portfolio? How do you set up the Conversions API? How many new ad concepts will you produce each month, and who makes them? What will you optimise for: leads, qualified leads or sales? How will leads reach my team, and how fast? What does your report show? What happens in the first 30 days? Specific answers mean experience; vague talk about "targeting the right audience" means the agency is a few years behind how Meta works now.

Red flags

Boosting posts instead of running campaigns. No mention of the Conversions API. Reports built on reach, likes and cost per click. One ad running for months. Optimising for traffic when you need leads. Owning your ad account. Promising a cost per lead in the first conversation. Changing everything every few days, which keeps campaigns permanently in learning.

One more: an agency that never asks what happens to a lead after the form. Most Meta lead problems are follow-up problems. If nobody calls within the hour, the best campaign in the world produces disappointing numbers, and an agency worth hiring will raise that in the first week rather than adjusting audiences to hide it.

What results look like

Week one is setup and tracking. Weeks two to six are testing: several concepts, broad audiences with hard exclusions, fast follow-up on every lead. Weeks seven to twelve scale what works in steps of 20 to 30 per cent and retire what does not. By the end of the first quarter you should know your real cost per qualified lead or sale and what moves it. For our clients, Meta has been part of results such as Careers Ninza filling its first batch with 35 admissions from 150+ qualified leads, and RAP Education growing from 4 to 5 admissions a batch to 30 or more every month.

Next step

If you are comparing providers for Facebook and Instagram ads, the quickest way to see whether we are a fit is a discovery call. It is paid, $9 in the USA, UK, UAE and Canada or INR 499 in India, and lasts 45 to 60 minutes with a senior consultant, not a salesperson. Bring your current ads, what a customer is worth to you and how leads are followed up. We will show you what we would test first.

Our services start at $500 per month in the USA, UK, UAE and Canada and INR 35,000 per month in India. You own every account, page and piece of data, and we report on leads and sales, not vanity numbers. We will tell you plainly if your constraint is the offer, the price or the sales process rather than marketing.

Apply for a discovery call through the short form on this page, or message us on WhatsApp.
