FAQ
Agency creative testing, answered
What is ad creative testing software for agencies?
Ad creative testing software helps agencies compare client ad variants and learn which creative attributes track with stronger performance. We built GetCrux as a creative testing platform for agencies: we use live campaign data to compare client ad variants, identify performance patterns, generate new assets and report results across accounts.
Which ad platforms do you support for creative testing?
We bring creative performance from supported Meta, Google and TikTok accounts into one reporting workflow, so you can compare the same concept across campaigns, placements, formats and platforms. You can resize assets for supported placements and publish through connected ad platform workflows, including Meta.
Do you run A/B tests or declare statistically significant winners?
No. For randomized A/B or multivariate assignment, use the experiment tools provided by the ad platform. We analyze the resulting creative performance and help you prepare the next variants.
We don't replace statistical-significance, incrementality, holdout or power-analysis tooling, and we don't automatically declare winners or change campaign budgets.
Can I evaluate creatives on each client's own KPIs and attribution?
Yes. We support platform metrics, configurable attribution windows and custom metrics based on your client's reporting logic. When available through a connected source, you can evaluate creative on CAC, ROAS, revenue, LTV or another client-specific KPI.
Our attribution and analytics integrations include AppsFlyer, Northbeam, Triple Whale, Adjust and Singular. Data and BI connections include Snowflake, Databricks, Amazon S3, Postgres, Power BI, Tableau, Sigma, Looker and Metabase.
How do you handle multiple client accounts?
You can configure multiple ad accounts, collaboration roles, permission controls and shared reports, and reuse label structures across accounts under the same company while client metrics, performance criteria, attribution settings and reporting views stay specific to each account.
Do audience breakdowns isolate audience effects from creative effects?
No. Audience labels and breakdowns show how creative performance varies between segments. They don't isolate audience effects from creative effects in a controlled experiment.
