Why SKUDrift
Validation only tells you so much.
Every existing tool checks one source in isolation. Nobody checks the gap between them, which is exactly where drift lives.
| Check | ||||
|---|---|---|---|---|

Feed validator. Checks your feed against Google’s rules. It catches a malformed price, but not a valid price that differs from your page.
Schema validator. Checks the structured data on a page. It catches broken markup, but not valid markup that disagrees with your feed.
Crawler. Reads what is on the page. It catches missing or broken pages, but doesn’t compare the page with your feed or markup.
SKUDrift. Compares all three for the same product and shows where they stop agreeing, with the value from each source.
From data to action
Don’t just find the issue.
Know how to fix it.
Every finding links to the affected products, the value in each source, and where it was captured.

Questions
Before you sign up.
Do I need to install anything?
No. You share the product feed you already send to Google, and SKUDrift reads your public storefront pages. No plugin, no code.
Is my data safe?
SKUDrift only reads public product data and your feed. Nothing is changed in your store, and you can ask us to delete everything at any time.
What does it cost?
Early access is free, including a one-off drift report on up to 5 products. Pricing for full catalogues will be shared before launch.
Which platforms does it work with?
Any store that sends a feed to Google Merchant Center, whatever commerce platform it runs on, including custom builds.
How is this different from a feed validator?
Validators check one source against rules. SKUDrift checks whether your sources agree with each other, the gap validators can’t see.
