# Events, Parameters and Conversions

Reliable analytics depends on describing user actions consistently. Events record that something happened, parameters describe the context, and conversions—or key events in current GA4 terminology—identify outcomes that matter to the business.

## Events

Examples include `page_view`, `form_start`, `generate_lead` and `purchase`. Prefer platform-recommended event names where applicable, and use a consistent naming convention for custom events.

## Parameters

Parameters add details such as `form_name`, `button_text`, `currency`, `value` or `item_id`. Send parameters only when they are useful, consistently populated and permitted by privacy rules. Do not place names, email addresses or other personally identifiable information in event fields.

## Conversion events

A conversion is an event designated as a valuable outcome, such as a qualified lead or completed purchase. Not every click should be counted as a conversion. Define the success condition, deduplicate repeat submissions where appropriate, and distinguish micro-conversions (for example, newsletter sign-up) from primary business outcomes.

## Implementation workflow

1. Write a tracking specification with event name, trigger, parameters and business meaning.
2. Implement through the approved tag or application setup.
3. Test expected actions and edge cases, including errors and repeated clicks.
4. Verify event payloads and parameter values in debugging tools.
5. Mark only agreed outcomes as key events and test downstream reporting.
6. Record changes and retest after site or tag updates.

## Example specification

For a completed enquiry, fire an event only after the application confirms successful submission. Include a stable form identifier and, if appropriate, lead type. Do not fire merely when the submit button is clicked, because validation errors may prevent the enquiry from being sent.

## Common tracking defects

- Events fire twice because both hard-coded tags and tag-manager rules are active.
- Names differ by capitalization or spelling.
- Parameters are missing, inconsistent or sent as the wrong data type.
- Conversions fire before success is confirmed.
- Testing data is mixed with production data.
