Question 1

Where do I edit a project?

Accepted Answer

Open the project from your dashboard and click the Edit button (or visit the project's settings page directly). The page header reads &ldquo;Edit Project&rdquo; with the description &ldquo;Update your project settings.&rdquo; Save changes at the bottom; the updates apply immediately.

Question 2

Who can edit project settings?

Accepted Answer

Owners and admins. Members and viewers can view a project but can't change its name, URL, integrations, or timezone. If a member needs a setting changed, an owner or admin can do it for them.

Question 3

Why is the Platform field read-only?

Accepted Answer

Once a project is created, its platform (the underlying runtime — Custom JS or Shopify) is locked. Changing platforms would invalidate the install snippet and history. If you've genuinely changed platforms, create a new project for the new platform and migrate intentionally.

Question 4

What's the Setup guide picker for?

Accepted Answer

Some runtimes have multiple install styles. Picking a different guide changes the on-screen install instructions to match how you actually deploy — for example, a Custom JS project might offer guides for Webflow, WordPress, Wix, and others. The runtime stays the same; only the displayed walkthrough changes.

Question 5

What does the Reporting timezone override do?

Accepted Answer

Otter A/B groups visitors and conversions into day buckets for reports. By default the buckets follow your account's reporting timezone. If a particular project needs a different timezone — say you have a US store on a UK account — set the override here. Leaving it blank inherits the account default.

Question 6

How is the project URL used?

Accepted Answer

Two places: the snippet verification check (so we know which domain to look for the snippet on) and as the default base URL when you build tests in the wizard. It doesn't restrict where the snippet can run — the snippet works on any page the install includes.

Question 7

What's the difference between the GA4 toggle here and the GA4 Integration section?

Accepted Answer

Two different directions. The toggle on this page (Google Analytics 4 under Analytics Integrations) forwards Otter A/B events into GA4 via gtag — so test impressions and conversions show up in your GA4 reports. The GA4 Integration covered in a separate help article goes the other way: it pulls existing GA4 events into Otter A/B as goals. You can use either, both, or neither.

Question 8

What events get forwarded to GA4 and GTM?

Accepted Answer

Three events per visitor: an impression (when they're assigned a variant), a conversion (when they convert on a goal), and a revenue event (when the goal carries a monetary value). GA4 receives these via gtag as experiment_impression, otterab_conversion, and otterab_revenue. GTM gets the same data in window.dataLayer, with the impression named otterab_experiment_impression and the other two unchanged. Each event carries the test ID and name, the assigned variant's ID and name, and (for conversions and revenue) the goal name and type — so you can join or segment on either side.

Question 9

Do I need a GA4 Measurement ID to enable the toggle?

Accepted Answer

Only if you don't already have gtag on your site. If your site already loads gtag (via your GA4 install), leave the Measurement ID blank and Otter A/B will use the existing gtag. If you don't have gtag yet, fill in the Measurement ID (it starts with G-) and Otter A/B will load gtag for you.

Question 10

Can I delete a project?

Accepted Answer

Yes — from the Edit Project page. Deletion is permanent and cascades to that project's tests, visitors, events, goal templates, and GA4 connection. There's no undo. If you just want to step back from a project temporarily, archive its running tests instead.
