SERP Split
What it is
SERP Split is a free web tool for evaluating SEO changes with holdout experiments on similar pages. Users upload a CSV with URL and click columns to create test and control groups through stratified sampling. For analysis, they 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. Changes that can be evaluated include meta titles, H1s, internal links, templated copy, AI content, FAQs, schema, and performance fixes. SERP Split recommends running tests for about 21–30 days and isolating one main variable in the test group. Its data guidance suggests 100,000 or more clicks across pages over roughly the last 100 days, while noting that lower volume may reduce confidence. The privacy policy says tool data is processed locally and temporarily, not stored, retained, logged, or transmitted for storage. It also says the service does not collect, store, or process personal data, though it uses limited non-personal tracking cookies for aggregated usage measurement and tool interaction insights. The listed free plan is free.
