Facebook Ads Agency
Precision targeting meets creative scale. 3B+ monthly users, one platform.
Facebook remains the world's most powerful advertising platform — 3B+ monthly active users, the most sophisticated ad auction system in digital marketing, and an AI engine that has fundamentally changed how campaigns are built and optimised. We run Facebook Ads across the full Meta stack: Advantage+ Shopping, Custom Audiences, CAPI integration, and creative testing at scale. For hands-on Facebook marketing strategies for brands, Social Media One delivers campaigns for Henkel, Toyota, and PURELEI.
Meta Advantage+ Shopping Campaigns
Advantage+ Shopping Campaigns (ASC) are Meta's AI-powered campaign type that automates audience selection, budget allocation, and creative delivery simultaneously. Instead of defining fixed ad sets, ASC tests up to 150 creative combinations and allocates budget to the top performers in real time. Meta's own data shows an average +12% ROAS uplift versus manually structured campaigns — making ASC the default starting point for e-commerce advertisers with a product catalogue. We layer ASC with manual campaigns for high-intent retargeting segments that benefit from tighter control.
Custom Audiences & Lookalike Strategy
Precision targeting is the engine of Facebook's performance advantage. We build layered audience architectures across four Custom Audience types:
- Customer List Audiences — CRM uploads hashed by email/phone for retention and upsell campaigns
- Website Visitor Audiences — Pixel-based segments by page visited, time on site, and purchase stage
- Engagement Audiences — Users who interacted with your Facebook/Instagram content, video, or lead form
- Video Viewer Audiences — Segmented by percentage viewed (25% / 50% / 75% / 95%) for sequential storytelling
From these we build Lookalike Audiences: 1% Lookalikes (tightest match, highest conversion probability) for performance campaigns, 2–5% Lookalikes for reach expansion. Advantage+ Lookalike Audiences (LLA) let Meta's algorithm dynamically extend the similarity threshold when it detects higher-quality signals — combining precision with scale.
Meta Pixel + CAPI: iOS 14+ Compliant Dual Tracking
Browser-based tracking via Meta Pixel alone loses 20–40% of conversion events due to iOS App Tracking Transparency, Safari ITP, and ad blockers. The Conversions API (CAPI) sends event data directly from your server to Meta — bypassing client-side restrictions entirely. Running both in parallel with deduplication enabled (matched by event ID) maximises signal fidelity. We target an Event Match Quality (EMQ) score of 7 or above, which Meta correlates directly with lower CPAs and improved automated bidding accuracy. CAPI setup typically recovers 15–30% of previously unmeasured conversion events.
CPM Benchmarks (UK/EU, 2026)
Realistic cost benchmarks for budget planning: Video Ads average £4–12 CPM depending on audience size and seasonality. Collection Ads (combining video cover with a product grid) run at £6–18 CPM but typically deliver significantly higher engagement and conversion rates — making their effective cost per conversion competitive despite higher CPMs. Story and Reels placements trend 20–35% below Feed CPMs and are often the most efficient awareness channel.
Combine Facebook Ads with LinkedIn Ads Agency for B2B audiences or Email Marketing Agency for lower-funnel nurturing — the two channels reinforce each other with Custom Audience syncing.

Frequently Asked Questions
Everything you need to know about Facebook Ads.

A Facebook Ads agency plans, builds, and continuously optimises paid campaigns across Meta's platforms — Facebook, Instagram, Messenger, and the Audience Network.

Facebook ad costs depend on your objective, audience, industry, and seasonality. UK/EU average CPMs range from £4–12 for Video Ads and £6–18 for Collection Ads. Most brands see meaningful results from £1,500–3,000 per month in ad spend. Agency management fees are charged separately. We work with brands from £2,000/month combined upwards and provide a tailored forecast before any commitment.
-
Advantage+ Shopping Campaigns (ASC) use Meta's machine learning to automate audience selection, budget allocation, and creative delivery across up to 150 creative combinations simultaneously. Meta reports an average +12% ROAS improvement versus manually structured campaigns. ASC is the recommended starting point for e-commerce advertisers with a product catalogue. We typically run ASC for broad prospecting and pair it with manual campaigns for high-intent retargeting segments.
-
Meta Pixel uses browser cookies, which are blocked by iOS App Tracking Transparency, Safari ITP, and ad blockers — causing 20–40% of conversion events to go unmeasured. The Conversions API (CAPI) sends events directly from your server to Meta, bypassing these restrictions. Running both in parallel (with event deduplication via matched IDs) improves your Event Match Quality score. We target EMQ 7+, which Meta directly correlates with lower CPAs and more accurate automated bidding.
-
Format performance depends on your objective. Video Ads on Reels and Stories are the most cost-efficient for awareness (CPM £4–12). Carousel Ads work well for consideration campaigns with multiple products. Collection Ads drive e-commerce conversions through an immersive mobile experience. Lead Ads reduce friction for lead generation by keeping users on Facebook. Advantage+ Shopping dynamically tests and serves the best-performing format automatically — making it the most versatile option for conversion-focused campaigns.
