Stop Burning
Ad Spend
On Broken Data.
If iOS14+ broke your attribution, your agency is optimising against phantom data — and you're paying for it. We fix your tracking at the server level, build creative that converts, then let Meta's algorithm compound the results. No guesswork. No excuses.
Your Agency Can't Fix
What They Can't Read.
When an API breaks, most ad agencies don't notice — they just keep spending. Our team comes from technical systems and custom web architecture, not media buying. We treat your Meta account like a software pipeline: we instrument it, monitor it, and only scale it once the data is clean. That's the difference between an agency that reports ROAS and one that engineers it.
Three Pillars.
One Machine.
Most agencies skip straight to media buying. We build the foundation first — because scaling broken infrastructure just loses money faster.
Fix the Leaks First
You're likely losing 30–40% of purchase signals right now — and your agency has no idea. We audit your full tracking stack, then implement server-to-server CAPI so every conversion your pixel misses gets captured directly from your server.
Tracking & InfrastructureCreative That Earns Its Budget
Bad creative wastes good data. We source real creators, write scripts built on direct-response principles, and launch 10–15 native UGC variations at a time — giving the algorithm enough signal diversity to find your best-converting audience at scale.
Creative LayerScale What's Working. Kill What's Not.
Once tracking is clean and creative is converting, we deploy automated budget rulesets that run 24/7. Winning ad sets get compounded. Losers get cut before they drain your margins. No emotion. No lag. Just clear, measurable decisions made at machine speed.
Media LayerThe Problem Is
Industry-Wide.
These aren't our numbers — they're published benchmarks from Meta, AppsFlyer, and Statista. They show exactly why tracking infrastructure has to come first.
Of Purchase Events Are Lost
On browser-pixel-only setups, iOS App Tracking Transparency causes roughly 30–40% of purchase signals to disappear before they reach Meta. The algorithm optimises against incomplete data — and your CPA rises accordingly.
More Conversions Attributed with CAPI
Businesses that implemented Conversions API alongside the Meta Pixel saw on average 19% more attributed website conversions, per Meta's own published case data. Server-side tracking recovers what the browser loses.
Higher ROAS with Advantage+ Shopping
Meta's Advantage+ Shopping Campaigns delivered on average 2.5× higher return on ad spend versus manually structured campaigns in published advertiser tests — but only when fed clean, high-quality conversion signals. Bad data in, bad results out.
Of Consumers Trust UGC Over Brand Ads
62% of consumers say user-generated content is the most authentic form of advertising — more than polished brand creatives. Native UGC formats consistently outperform studio-produced video in direct-response Meta campaigns.
A note on results: Siderium is a new agency. We don't yet have our own client case studies to show you — and we won't fabricate them. The benchmarks above are published third-party data showing what properly implemented CAPI and Advantage+ can deliver. Your actual results will depend on your product, margins, audience, and creative. We'll tell you what's realistic for your specific account on the strategy call.
Skin in the Game.
Not Retainer Capture.
We charge a flat fee to build the infrastructure. After that, our compensation scales with your ROAS — so we're incentivised to perform, not just to invoice.

You're Spending on Ads
US-based e-commerce brands doing $20k+ MRR in Premium Tech, Functional Wellness, or Pet Care — with at least $5k/mo in active Meta ad spend.
Your Attribution Feels Off
Post-iOS14, your reported ROAS looks fine — but revenue isn't moving. You suspect your data is broken but don't know where the leak is.
You Want a Partner, Not a Vendor
You're done paying flat retainers to agencies that report vanity metrics. You want a team whose income depends on your actual results.
