What AppTweak's 2026 Report Actually Tells Apps to Fix

The 2026 AppTweak report on App Store Optimization (ASO) and Apple Search Ads (ASA) trends highlights a significant disconnect between industry best practices and the actual behavior of most mobile app teams. The primary thesis is that many developers are neglecting low-cost growth opportunities, specifically through A/B testing and consistent metadata iteration, while failing to adapt to evolving ad placement dynamics.

Data from the report reveals a surprising lack of experimentation, with 90% of apps failing to A/B test their icons or videos. While top-performing apps and games demonstrate a clear correlation between high download rankings and frequent metadata updates—with top games updating screenshots approximately 12 times annually—the broader market remains stagnant. The analysis suggests that teams are effectively paying for traffic without optimizing the conversion rates of their store assets, representing a missed opportunity for efficient growth.

Regarding Apple Search Ads, the report analyzes the impact of new search result placements introduced in March 2026 across approximately 2,800 US advertisers. While Discovery campaigns experienced substantial growth in reach—including a 44.9% increase in impressions and a 41.6% increase in taps—they were the only campaign type to see an increase in cost per install, which rose by 4.3%. Conversely, Brand, Generic, and Competitor campaigns saw decreases in cost per install ranging from 2.6% to 3.8%. The findings suggest that the rise in Discovery costs is likely linked to the introduction of "Maximize Conversions" campaigns, which mandate the use of automated search match groups that target lower-volume, previously untapped keywords.
