SERP Split
What SERP Split is
SERP Split is a free web tool for comparing test and control groups of similar pages and assessing SEO-related traffic changes. Users upload a CSV with URL and click columns, and the tool creates the groups using stratified sampling. For analysis, users upload daily traffic data with date, test_traffic, and control_traffic columns. The site says it measures uplift and confidence using Bootstrap Casual Inference; its results preview includes uplift, absolute clicks, a p-value, significance, and an exportable graph. Examples of testable changes include meta titles, H1s, internal links, templated copy, AI content, FAQs, schema, and performance fixes. The site recommends running tests for about 21–30 days and isolating one main variable to the test group. Its data guidance suggests 100,000 or more clicks across pages over roughly the last 100 days, noting that lower volume may reduce confidence. The privacy policy says tool data is processed locally and temporarily and is not stored, retained, logged, or transmitted for storage.
