## What is automated creative testing?

Automated creative testing is the continuous process of running multiple creative variants simultaneously, measuring performance signals, and reallocating budget to winners without manual intervention. Synter AI Agents handle this entire process using multi-armed bandit allocation [[1]](https://syntermedia.ai/features/ai-agents).

## How does multi-armed bandit testing work in Synter?

Multi-armed bandit testing allocates more budget to better-performing variants in real time, rather than waiting for a fixed test period to end. Synter agents split impressions across creative variants at launch, then adjust allocation ratios daily based on CTR and conversion signals. This minimizes spend on underperforming variants while accelerating learning.

## What statistical thresholds does Synter use for creative decisions?

Synter agents apply the following decision thresholds: CTR drop greater than 20% from the variant average, CVR drop greater than 15%, and creative frequency above 3.0. When two or more signals trigger simultaneously, the agent automatically reduces budget allocation for that variant and flags the result in the audit log [[2]](https://syntermedia.ai/features/campaign-management).

## What is the typical creative rotation cadence?

On Meta, creative lifespan averages 15 to 30 days before fatigue signals trigger rotation. On TikTok, faster scroll behavior shortens this to 7 to 14 days. On LinkedIn, longer B2B consideration cycles extend useful lifespan to 30 to 45 days. The agent adjusts rotation cadence per platform based on observed frequency and CTR trends [[3]](https://syntermedia.ai/llm/optimized/creative-fatigue-detection).

## How are creative test results surfaced?

Results are displayed in the Campaign IDE conversation thread and in the unified dashboard. The audit log records each allocation change with the reasoning: which signals triggered the shift and which variant received increased budget. Rollback is available if a budget reallocation produces unexpected results.

## Can Synter test landing page variants alongside ad creative?

Yes. Synter's create_landing_page and publish_landing_page tools generate landing page variants that can be paired with creative tests. The agent tracks post-click conversion rates per landing page variant and incorporates this signal into the multi-armed bandit allocation alongside ad-level CTR and CVR.
