The Meta Ads System Working in 2026
Nick Shackleford, co-founder of Structured Agency and partner at Brez, explains why Meta ads still work in 2026 — founders just aren't reading the right signals anymore. Rather than a platform problem, Shackleford argues the issue is that most founders are using outdated playbooks from the growth-at-all-costs era and failing to understand how Meta's AI systems now evaluate and allocate ad spend, making success dependent on business fundamentals, offer strategy, and creative diversity rather than media buying alone.
Key takeaways
- • Meta's algorithm has fundamentally shifted — it now uses advanced AI systems like Andromeda to bucket customers by natural CAC and expected spending patterns, requiring founders to present diverse offers and landing pages rather than relying on a single product positioning.
- • The biggest scaling mistake is running too many ads in too few campaigns, which dilutes Meta's ability to identify winners; instead, use a "graduation period" approach where proven ads are duplicated and isolated into separate campaigns to let them flourish.
- • Offer and business model trump media buying — at scale, success depends more on AOV manipulation, bundling strategies, and landing page optimization than on ad account optimization, making this fundamentally a business problem not a creative one.
- • Use the "accordion view" decision framework — make daily budget decisions based on the past day's data, then validate against 3-day and 7-day trends before scaling, and track hourly updates when spending at highest levels to catch profitable or unprofitable shifts before they compound.
- • Repeat purchase rate is a true product-market-fit indicator — if customers aren't coming back on their own after an initial purchase, the product may not have real market fit despite initial sales, signaling the need to revisit positioning or product quality rather than spend more on ads.
- • Founders must understand their contribution margin, CAC, and LTV numbers with precision before handing budgets to agencies; vague ROI targets like "3x ROAS" are meaningless without knowing exact product costs, shipping, and customer acquisition economics across new vs. returning customers.
- • Creative should follow a smoke-test-to-investment hierarchy — start with low-cost static images or AI-generated concepts, graduate to motion graphics only if they perform, then move to full UGC/video only after validating multiple times, avoiding wasteful high-production spending on unproven concepts.

"Meta ads don't work anymore. You probably thought it, said it, or heard another founder say it after one bad month of performance."
