WordPress A/B testing questions

Does Otter work with WordPress page builders?

Yes. Otter edits the rendered page in the browser, so it works with Elementor, Gutenberg, Divi, and most other page builders.

Do I need to edit my WordPress theme?

No. A header plugin can install the Otter snippet across the site without modifying theme files.

Can I A/B test WooCommerce?

Yes. Otter also provides an official WooCommerce plugin with automatic product, checkout, purchase, and revenue events.
