# frontend-conversiontracking

Set of front-end javascript tools to handle Online Activity conversion tracking. 

## Prelander usage
When using a prelander hosted on a different domainname; you need to pass tracking variables to the landingpage. This modifies links and forms to include variables. 

*When using redirects (for ex: javascript) other than links or forms, you'll need to manually append the click-id variables*

    <script defer 
		src="https://cdn.jsdelivr.net/npm/oa-frontend-conversiontracking@1/dist/prelander.min.js"
		data-params="oa_clickid,subid2">
	</script>
