What is SERP Similarity?
SERP Similarity measures how alike the search results are for two different keywords. We analyze the top ranking URLs for each keyword in real-time.
A high similarity score (above 30-40%) means Google sees these keywords as having similar search intent—they can likely be targeted with a single piece of content.
Understanding this is vital for efficient keyword grouping and avoiding keyword cannibalization.
