1.72 → 3.2×ROAS in three months for a DTC food brand — cleaned of pixel mis-attribution
3×+ROAS held for two full years for a UAE hair-care brand
€31.50per ready-to-buy enquiry for a €300–900 B2B product
We report the numbers the ads actually drove — never what a flattering pixel claims.
The work
Ads we've actually made.
Real campaigns from real accounts — hair care in the UAE, food in Ireland, agri-tech in Serbia. Every one tested against alternatives before it earned its budget.
A selection of ads we proposed and built. The Nola comparison angle's family reached a 7.1× ROAS at its peak.
What happens on the call
Thirty minutes. Three steps. Zero pressure.
1 · You talk, we listen
Your business, your goals, what your ads are doing today — and what's been frustrating you about them.
2 · An honest verdict
We tell you straight whether paid social can grow your business right now — and whether we're the right people to run it.
3 · A next step, only if it fits
If it makes sense, a fixed-fee €200 audit turns the call into a concrete plan — refunded if it shows no clear value, credited toward your first month if we work together.

Proof, not promises
Three brands, three honest stories.
OAC Snacks — from 1.72 to 3.2× ROAS, honestly.
DTC FOOD · IRELAND · META, GOOGLE & PINTEREST
They arrived at a 1.72× ROAS with a pixel counting the brand's own internal purchases as ad revenue. We fixed the tracking first, then rebuilt the account as one system: 20+ creative angles tested across six themes, retargeting structured as its own funnel stage (converting at 25%), Google Search protecting the brand at €0.49 a click — all read through one Looker Studio dashboard.
3.2× blended ROAS in three months — cleaned of mis-attribution — then handed over fully documented when OAC brought paid media in-house. A planned, successful exit.
The actual dashboard every decision was read through.
Nola by Gala — a held 3×+ ROAS in the UAE.
DTC HAIR CARE · UAE · META · TWO-YEAR PARTNERSHIP
A blank Meta account in a crowded, claim-heavy market. We made creative the engine — video-first, ingredient-led, tested relentlessly — and built reporting the brand could finally trust. ROAS moved between 3× and 6× with the seasons and never fell below 3× in two years, holding even after we fixed the pixel and tightened attribution: 3.26× prospecting, 4.5× retargeting, 18.8% click-to-landing conversion.
From our monthly report — the first clean month after the pixel fix.
HektarMeteo — ready-to-buy growers at €31.50 each.
B2B AGRI-TECH · SERBIA · META LEAD GEN
A €300–900 considered purchase, a niche audience of growers, a lean budget. We built a two-track lead engine — a free eBook plus direct product enquiries — with creative, targeting and landing pages all designed by us. On roughly €880 of spend: 28 sales-ready enquiries at €31.50 each and 447 eBook leads at €1.97, until the pipeline outran the team's capacity and campaigns were paused by choice.

Who you'll be talking to
Your call is with the founder.
No sales team, no account managers — the person on the call is the person who'd run your strategy.
Nadja was a media buyer first — years of hands-on Meta advertising before she founded Southside Social. Along the way she became an activist, taking everything the ad accounts had taught her — audiences, messages, relentless testing — into advocacy, and building a community around it. Same craft in both places: find the real story, put it in front of the right people, and never waste their trust.
Behind her is a deliberately small team — strategy, paid media and design — so senior hands stay on every account. Tracking fixed before a cent is spent, numbers cleaned of anything flattering but false, and everything we build stays yours.

Before you book
The questions everyone asks.
Is this actually free, or is it a sales pitch?
Actually free. Thirty minutes, no deck, no pressure. If we don't think we can help, we'll say so on the call — and tell you what we'd fix if we were you.
What happens after the call?
Only if it makes sense for both sides: a fixed-fee €200 audit of your accounts, delivered in 1–2 weeks. It's refunded if it shows no clear value, and credited toward your first month if we end up working together.
We already run ads / have an agency. Is the call still useful?
Especially then. A second pair of senior eyes on your account structure, tracking and creative usually finds something — and you keep whatever we spot, whoever ends up running the ads.
Which platforms do you run?
Meta, Google, Pinterest, TikTok and LinkedIn — as one connected system, not five silos. Meta creates demand, Google captures intent, Pinterest and TikTok drive discovery, LinkedIn reaches B2B.
