Optimising Paid Social After Meta’s Server-Side Update

If you’ve been running Meta ads over the past few years, you’ll know the struggle is real.

Since Apple’s iOS 14 update in 2020, Meta advertisers have grappled with reduced access to user data, leading to gaps in tracking conversions and optimising campaigns. This has pushed Meta Ads Manager toward more reliable methods, emphasising Server-Side Tracking to rebuild signal quality.

If you want to maintain strong ROAS, understanding these changes isn’t optional anymore.

Meta is projected to capture 60% of global social media advertising spend this year.

With that in mind, below we share our top 3 tips for navigating this shift with emphasis on Meta.

Prioritise High-Quality Signals Today

The foundation of effective paid social ad optimisation lies in accurate data.

Browser-based pixels often miss at least 20% of events due to ad blockers and device privacy restrictions. This skews paid social performance reports and leaves you flying blind on conversions.

Meta’s Server-Side Tracking solution via Conversions API (CAPI) is designed to bypass browser (client-side) hurdles by sending events directly from your server to Meta.

Why CAPI Matters

Implementing CAPI alongside browser pixels creates a dual-tracking setup that can recover lost data.

In fact, Meta has evidenced that businesses using CAPI report up to 22% better performance in attribution accuracy. This means clearer views of customer journeys, from awareness to purchase, enabling more precision in bidding and audience building.

Getting Started

If you haven’t already implemented a server-side solution, our advice is to do so soon.

At a minimum, advertisers should ensure events like purchases and leads flow server-side to boost signal quality. Start with tools like Google Tag Manager for Server-Side to test then aim for 50-100 optimisation events in the first week to accelerate learning phases.

Our own clients benefit from this setup via more accurate ROAS figures which helps us avoid over or under-spending on creatives (bringing us to the next topic).

Creative-Centric Optimisation as the New Targeting

Although signals are important, we have always prioritised creatives as the primary driver in Meta campaigns.

Traditional audience layering and segmentation tweaking is giving way to AI-led matching where diverse ad assets guide delivery. This is especially true of Meta’s Advantage+ campaigns which automate placements and targeting

Simplify Your Campaign Structure

Throughout this year, we have noticed simplified campaign structures featuring just one ad set with 25+ ad variations outperforming more complex manual setups.

We’re seeing an average 37% lift in incremental conversions when we let the creative do the talking. This is especially true when running the same ads across funnel steps such as reach, traffic and conversion.

How to Approach

Typically we lean heavily into a client’s own organic social media content to meet ad variant quotas but we encourage the use of diversified ad assets across formats (static images, carousels and Reels) to feed the algorithm.

Here’s what we’ve observed:

Ad creatives often influence outcomes 10 times more than demographics. Why? Because AI analyses engagement signals like scroll time to pair ads with intent-matched users.

Not only does this translate to faster campaign setup times, but you should also experience 16-20% lower cost per conversion just from testing.

Timeline for “Upload and Go” Ads Manager Pivot

Let’s talk about where all this is heading.

Meta’s product development trajectory points to full automation by 2026, where advertisers input basics like budget and URLs then AI handles the rest. This “upload and go” model builds on current tools, reducing manual inputs in Ads Manager.

Meta’s Automation Timeline:

• 2021-2025: Server-Side Push (CAPI) – Essential for iOS attribution. Dual setup becoming (pixel + CAPI) becoming the standard. Streamlined integrations rolling out in 2025.
• Early 2025-2026: Andromeda Update – Meta’s AI engine consolidates campaigns and improves conversion matching. Full rollout completes through 2026.
• October 2025 onwards: Marketing API Updates – AI-led targeting focus with broader placements for Advantage+ campaigns.
• Late 2026: Full AI Automation – Brands upload images and budget; AI generates complete ads (creative and targeting). Phased testing throughout 2025.

What is Andromeda?

Meta Andromeda is an AI-powered ad retrieval engine that determines which ads are shown to users on platforms like Facebook and Instagram. Think of it as the brain behind your ad delivery.

As Andromeda fully deploys mid-2025, expect consolidated campaign flows that prioritise signals and creatives.

By 2026, automation will dominate the Meta campaign experience. We project at least 35% efficiency gains for early adopters over and above incremental conversion lifts.

The Bottom Line

The landscape’s changing fast, but the fundamentals remain: accurate tracking, strong creative, and preparing for increased automation.

Get server-side tracking implemented, test more creative variations, and prepare for full automation by 2026. Do this well and your paid social performance will stay strong as you scale.
