A good paid social agency is one that can show you real results from accounts like yours, with numbers you can check.
This directory lists paid social agencies, performance marketing agencies and freelance media buyers who publish their results, and links each one to the tests in our archive.
Start with the platform you spend most on, then check every case study the same way.
How the list works: published results only
We only list agencies and people whose results are public.
Most of them post account screenshots on X or publish case studies on their own sites, and we log those results in the ROASArchive database with the credit attached.
We have not hired any of them. We checked that each agency exists and does what we say on its own website, and we note when a number is self-reported. A listing is not an endorsement.
Here is the kind of evidence we look for.
A media buyer posting as @runtraffic reported November sales up 63% year over year after an agency takeover across Meta and Google.
The Moonlighters founder @SamPiliero showed a 45% drop in cost per purchase after cutting a product's price by €10 with the same ads and budget.
Agencies by platform and specialty
Most brands should pick an agency by the platform that drives most of their revenue.
Each directory below compares agencies on what they specialize in and the results they have published.
- Facebook ads agencies: Meta account structure, creative testing and scaling. The Moonlighters, founded by Sam Piliero, focuses on scaling ecommerce brands on Meta and Google.
- TikTok ads agencies: Spark Ads, creator content and app installs.
- Google Ads agencies: Search, Shopping, Performance Max and Demand Gen. JXT Group, founded by Menachem Ani, is a Google Premier Partner that also runs Meta and YouTube ads.
- Ecommerce ads agencies: Shopify brands that need paid ads, email and conversion work together. Budai Media covers Google Ads, email, SMS and Meta creatives, and its founder @thedanielbudai reported scaling revenue from $4.5k to $505k a month at a 2-2.5x ROAS with 10-15% budget steps.
- Ad creative agencies: hooks, statics, UGC and motion ads for brands that already have media buying covered. AdCrate, co-founded by Alex Cooper, says it works with brands spending $100K to $3M a month on paid.
- UGC agencies: creator videos and whitelisting. inBeat's Hurom case study reports a 65% lower CPA and 300% higher ROAS after moving from discount messaging to health-benefit creator videos (agency-reported).
Freelance media buyers and creative strategists
If you spend less than an agency's minimum, or want one senior person instead of a team, look at freelance media buyers.
Many of the best-documented results in our archive come from individuals who post their own account data.
For creative, a creative strategist plans angles and briefs before anything gets produced. @alexgoughcooper shared an ad built from old footage and B-roll that ran at a $58.61 CPA on $107k of spend.
A freelancer costs less and you work with the person doing the work.
The trade-off is less coverage when that person is busy or away.
What they charge
Agencies usually charge one of three ways: a percentage of ad spend, a flat monthly retainer, or a base fee plus a performance bonus.
Freelancers more often charge a flat monthly fee.
As one example, ATTN Agency's published guide to fee structures puts typical percentage fees at 10-20% at $5K a month of spend, falling to 8-12% at $100K.
Its own published rates go from 15% to 8% as spend grows.
That is one agency's view, not an industry survey.

How to check their case studies
Agency case studies are marketing, so read them like marketing. Before you sign, check these five things:
- Before and after: a result needs a starting number, not just a final ROAS.
- Spend and timeframe: a 5x ROAS on $500 over three days says little.
- What changed: the case study should name the change that drove the result.
- Attribution: platform ROAS can overstate results; ask for blended MER or incremental numbers.
- Similar accounts: ask for results in your vertical and at your spend level.
We grade every result in our database by evidence type.
Our guide on how reliable agency case studies are explains how a screenshot, a split test and a self-reported claim compare.
