Optux AI vs SERP Split

Optux AI is a web tool for A/B testing, SEO experiments, and website personalization. It compares page versions, can test temporary SEO changes such as H1s and meta descriptions without a full release, and can show different content to audiences in real time. Experiments run on Cloudflare Workers, and the documented setup requires websites to be proxied through Cloudflare. Automatic installation needs API access to the customer's Cloudflare account, with manual worker installation as an alternative. Optux AI supports single-page applications and lists integrations with Google Analytics 4, Segment, Mixpanel, Matomo, Heap, Hotjar, and custom setups. When enabled, experiment data can go to Google Analytics 4, and the product can optionally create audiences for new experiments. The Free plan lists one seat, 5K MTU for A/B and split testing, 500 MTU for AI text personalization, and one patch. Pro costs $39 a month, and Business costs $239 a month. Several targeting types, including behavioral, cookie-based, and time-based, are marked as coming soon.

SERP Split is a free web tool for SEO holdout experiments on similar pages. Users upload a CSV containing URLs and clicks to create test and control groups through stratified sampling. They then upload daily traffic data with date, test_traffic, and control_traffic columns for analysis. The site says uplift and confidence are measured with Bootstrap Casual Inference. Results preview uplift, absolute clicks, a p-value, significance, and an exportable graph. Test examples include meta titles, H1s, internal links, templated copy, AI content, FAQs, schema, and performance changes. The recommended test period is about 21–30 days, with one main variable isolated to the test group. Guidance suggests 100,000 or more clicks across pages over roughly the previous 100 days, while lower volume may reduce confidence. The listed search data source is Search Console, and organic traffic impact is the focus. Tool data is processed locally and temporarily, not stored or transmitted for storage. Personal data is not collected, stored, or processed, though limited non-personal cookies measure aggregated usage.
