Historian vs.
Google Analytics 4
GA tells you the numbers changed. Historian tells you what changed.
The short version
Google Analytics 4 is the standard for measuring traffic and conversions: free, deeply connected to Google Ads, with flexible events and attribution. Almost every e-commerce team has it.
What GA does not keep is the site itself. When conversion on a category page falls, GA shows the drop, but not that the banner changed, the sort order moved or a competitor launched a sale the same day.
Historian keeps that history, draws heatmaps on it and lets agents connect the change to the numbers.
Side-by-side comparison
| Google Analytics 4 | Historian | |
|---|---|---|
| Core question | How much traffic came, from where, and did it convert? | What changed on the site, and what did it do to revenue? |
| Data source | Google's tag, with events you configure | A tracking script on your store (sessions, page views, clicks, orders), a daily capture of your pages, and your ad accounts |
| Archive of the page itself | No — aggregated metrics only | Yes — your pages captured every day with a real browser, from the day you start |
| Change detection | No | Yes — what changed on the page, where and when, connected to the numbers |
| Heatmaps | No | Yes — on every captured version of the page, coloured by clicks, conversion or revenue per click, per template, device and traffic source |
| Attribution | Strong — channel attribution and native Google Ads linking | Traffic sources per page and per element, and your ad accounts next to the pages they lead to |
| AI | Generated insights and anomaly detection in the reports | A catalog of specialist agents that run on a schedule and deliver insights with an estimated revenue impact and the evidence |
| Price | Free; Analytics 360 for enterprises | Not published; we tailor it in a demo |
Key differences in depth
Metrics vs. memory
GA turns millions of interactions into numbers. Those numbers are the outcome of changes, not the changes themselves.
Historian stores the pages. The drop in the numbers and the change on the page can be put side by side, which is usually where the explanation is.
The element, not just the page
GA measures pages and the events you set up. Historian's tracking script records clicks on every element, and ties them to the orders that followed, so you can see what a click on each banner, button and product tile is worth, without a tagging plan.
Reports vs. agents
GA answers the questions you know to ask. Historian's agents run on a schedule and bring the findings to you: what changed, what it did, and what to do about it, with the evidence attached.
When each tool makes sense
Choose GA4 when:
- You need free, standard traffic and conversion measurement
- Channel attribution and Google Ads reporting are your main needs
- You have the people to build and read reports
Choose Historian when:
- You need to know what changed on the site, not just that the numbers moved
- You want to see any page as it looked on any day since you started
- You want to know what each element on a page earns
- You want agents to bring you the findings
Used together
There is no reason to drop GA. It tells you a landing page's traffic dropped; Historian shows the page versions from the weeks before, so you can connect the change to the drop.
