Google Ads conversion pixels carry the ID in the path

The conversion ID is a path segment, not a query parameter. Without it the pack cannot tell which conversion fired. label is expected: without it the hit lands on the account rather than a conversion action. value when present is numbers and decimals only, so 20.00 is valid and $20.00 is not.

Rules

Codes are stable. A finding in CI, MCP, or the playground lands on the same id.

Field	Required	What it checks	Rule ids	Source
`conversion_id`	required	It is the numeric conversion ID, unique per Google Ads account, and it travels in the path rather than the query. Fix: Copy the conversion ID from the conversion action's tag setup.	`vendor.google-ads-conversion.param.conversion_id.missing` `vendor.google-ads-conversion.param.conversion_id.empty` `vendor.google-ads-conversion.param.conversion_id.invalid`	docs
`label`	recommended	It identifies which conversion action fired. Without it, the hit lands on the account rather than on a specific action. Fix: Add the conversion label from the conversion action's tag setup.	`vendor.google-ads-conversion.param.label.missing` `vendor.google-ads-conversion.param.label.empty`	docs
`value`	optional	It is the conversion value. Google documents google_conversion_value as numbers and decimals only, with no currency symbol or comma. Fix: Send a number such as 20 or 20.00, not $20.00.	`vendor.google-ads-conversion.param.value.empty` `vendor.google-ads-conversion.param.value.invalid`	docs
`currency_code`	optional	It is the ISO 4217 currency of `value`. Google documents it on conversion tags as `currency_code`. Fix: Send the three-letter code, such as `USD`.	`vendor.google-ads-conversion.param.currency_code.empty` `vendor.google-ads-conversion.param.currency_code.invalid`	docs
`ord`	optional	It is the cache buster on the image tag. Google documents a unique `ord` so repeat fires are counted separately. Fix: Emit a fresh `ord` on every fire, or drop the empty pair.	`vendor.google-ads-conversion.param.ord.empty`	docs
`guid`	optional	The generated image tag sends `guid=ON`.	`vendor.google-ads-conversion.param.guid.empty` `vendor.google-ads-conversion.param.guid.invalid`	docs
`script`	optional	The image fallback sends `script=0` to say no JavaScript ran.	`vendor.google-ads-conversion.param.script.empty` `vendor.google-ads-conversion.param.script.invalid`	docs
