Keywords & Discovery

Keywords are the foundation of organic App Store Optimization. Cortex collects search suggestions, Apple Search Ads (ASA) Search Popularity metrics, and competitive density to help you choose high-intent terms.

Keyword Metrics

Every keyword in Cortex is evaluated against three core dimensions:

  1. Search Popularity (0–100): Derived from Apple Search Ads and live store search auto-complete frequencies. A popularity score above 40 indicates strong search demand.
  2. Difficulty Index (0–100): Measures how hard it is to break into the Top 10 rankings, based on the domain authority, download volume, and ratings velocity of current top-ranking apps.
  3. Relevancy Score: An AI semantic alignment score measuring how closely the search query matches your application's category, features, and target audience.

The Golden Ratio Formula: Focus your optimization on terms with high Popularity (>40) and moderate Difficulty (<50) where your app has direct semantic relevance.

Keyword Suggestion Engine

Cortex provides multiple discovery vectors:

  • Store Auto-Complete: Real-time keystroke predictions from Apple App Store and Google Play search bars.
  • Competitor Gap Analysis: Identifies terms where your top 3 competitors rank in the top 5, but your application is currently unranked.
  • Semantic Expansion: Uses LLMs to generate high-intent synonyms, long-tail phrases, and localization equivalents.
