Meta has been pushing Advantage+ (their fully automated campaign type) aggressively since 2022. The pitch: let the algorithm handle targeting, bidding, placement, and creative selection while you focus on providing good creative and a clear objective. In theory, the machine knows better than you do. In practice, the reality is more complicated.
How we set up the test
We ran 90-day parallel campaigns across six client accounts spanning three verticals: B2C e-commerce (two accounts), B2B lead generation (two accounts), and professional services (two accounts). Each account ran an Advantage+ Shopping Campaign or Advantage+ Audience campaign alongside an equivalent manually structured campaign with similar budgets, same creative assets, and same conversion objectives. We analysed ROAS, CPL, CPA, and reach metrics, and we considered vertical-specific context in interpreting the results.
E-commerce: Advantage+ wins, conditionally
For our two e-commerce clients, Advantage+ Shopping Campaigns outperformed manual campaigns on ROAS by an average of 28% over the 90 days. This was consistent with Meta's own published benchmarks and with third-party reports we'd seen. The algorithm's ability to dynamically allocate budget across placements (Feed, Stories, Reels, Audience Network) and its access to broader signal pools drove incremental conversions that manual audience targeting missed.
However: both clients had product catalogues over 500 SKUs and existing pixel data from 18+ months of conversion events. Advantage+ performs best when the algorithm has signal to work with. For newer accounts or smaller catalogues, the performance advantage diminished significantly in our testing.
B2B lead gen: manual wins, clearly
Both B2B accounts performed meaningfully better with manual campaign structures β 22% lower CPL on average. The reason: B2B audience definition matters in ways that the algorithm's broad targeting approach doesn't handle well. When you're targeting IT Directors at companies with 200+ employees in specific industries, the algorithm's expansion into "similar users" produces a lot of reach that doesn't convert.
Manual campaigns with tight Lookalike Audiences built from CRM uploads of actual qualified leads, combined with interest and job title layering, consistently produced better-quality leads at a lower cost. The machine's strength is finding conversions efficiently across a broad consumer market β it's less equipped for the narrower, intent-based targeting that B2B requires.
Professional services: mixed, context-dependent
The professional services results were the most interesting. One account saw better performance from Advantage+; the other performed better with manual. The difference came down to the existing audience size: the account with a larger existing customer base and more pixel data favoured automation; the newer account with limited historical data favoured manual control.
What this means for your account
Our updated approach based on this testing:
- For e-commerce accounts with 12+ months of pixel data and 100+ conversions/month: test Advantage+ Shopping. The probability of outperformance is high.
- For new e-commerce accounts or accounts with thin historical data: build manual campaigns first, generate conversion signal, then introduce Advantage+ after 90 days.
- For B2B lead generation: manual structures with carefully constructed Lookalike Audiences are still the better default. Test Advantage+ with a small budget allocation to monitor.
- For all accounts: don't treat Advantage+ as a replacement for good creative strategy. The algorithm optimises distribution and targeting β if your creative isn't driving engagement, automation can't fix it.
The creative question
One finding we didn't expect: the creative mix mattered more in Advantage+ than in manual campaigns. Advantage+ applies its own creative selection layer, favouring assets that drive initial engagement (often videos with text overlay or motion graphics in the first 3 seconds). Advantage+ accounts with diverse creative sets β multiple aspect ratios, multiple formats, 3+ video options β outperformed accounts with limited creative options by a wider margin than in equivalent manual campaigns.
