Most optimization tools are pure garbage because they’re built for people who don’t understand the platforms… if you actually know what you’re doing the native platforms give you everything you need plus the tools usually make decisions based on surface metrics that tank performance long term.
I manage accounts spending $200K+ monthly (so i know what works at scale) and honestly 90% of optimization is just checking the data daily and making small strategic adjustments based on what the numbers are telling you… the only external tool worth using is a proper analytics dashboard like Looker Studio or Supermetrics to pull cross-platform data into one view so you’re not tab-switching between Google Ads, Meta, GA4, and your CRM all day.
Main issue IMO isn’t tools… it’s knowing what to optimize for. Most people chase CPCs or CTRs when they should be focused on backend metrics like customer LTV, contribution margin per channel, and cohort retention rates because those determine if you’re actually making money or just burning budget on vanity metrics that look good in reports but don’t drive profit.
For my clients in ECOM and lead gen I build custom dashboards that show blended ROAS across all channels, new vs returning customer splits, and day-parting performance so we can shift budgets in real time based on what’s actually converting not what some AI tool thinks should work… the accounts that scale profitably are the ones where decisions come from understanding the business economics not from letting software auto-optimize toward the wrong goals.
