Analysis Methods

Quick Wins Detection

Finds pages with high potential based on:

•Position 4-15 (close to page 1 or top 3)
•High impressions relative to clicks
•Low CTR vs position average
•Keyword difficulty feasibility

Content Gap Analysis

Identifies opportunities by:

•Queries with impressions but no clicks
•High-impression queries without dedicated content
•Related queries not covered by existing pages

Decline Detection

Monitors for:

•Position drops > 3 positions
•CTR drops > 20%
•Click volume decline > 30%
•Impression drops (may indicate SERP feature loss)
