Standard event explained — the predefined conversion events each ad platform supports, and why they are usually safer than custom names.

Updated July 22, 2026.
A standard event is an advertising platform’s predefined event name for a common action such as Purchase, Lead, AddToCart or ViewContent.
Why it matters
Standard events reduce ambiguity. Platforms can attach known reporting, audience, catalog and optimization behavior to a recognized event. A custom name that duplicates a standard action usually adds complexity without adding information.
How it works across ad platforms
Platform or system
Current treatment
Meta
Standard Pixel/CAPI events cover commerce, lead, registration, appointment and subscription actions.
TikTok
Standard events support reporting, optimization and audiences; TikTok migrated SubmitForm to Lead and CompletePayment to Purchase.
Reddit
Eight standard events: PageVisit, ViewContent, Search, AddToCart, AddToWishlist, Purchase, Lead and Sign Up.
Pinterest
Twenty current event types including Checkout, Lead, Signup, Subscribe and Custom.
Google Ads
Uses conversion-action categories rather than a shared browser standard-event dictionary.
LinkedIn
Uses current conversion categories such as Lead, Qualified Lead, Purchase and Other.
Microsoft Advertising
Uses destination, engagement, custom-event, app and offline goal types.
Implementation rules
Use the standard event only when the platform definition matches the business action.
Follow the platform’s exact capitalization/token in code.
Send required product, value or currency parameters for the use case.
Do not invent a standard event that appears in another platform but not this one.
Check whether the standard event is eligible for the campaign objective.
Common mistakes
Using Purchase when checkout merely started.
Using Lead for a page view or form start.
Copying an event name from Meta into Reddit or Pinterest without checking official support.
Continuing deprecated TikTok names in a new implementation.
Minimum QA
Confirm the event appears with the intended official name.
Inspect required parameters.
Verify the action definition against source-system data.
Confirm eligibility for bidding, audiences or catalogs.
