Once you’ve set up a website tag, reporting for website conversion tracking is available in the "Campaigns" tab. You’ll see the number of conversions driven at the campaign or Tweet level, as well as related metrics such as impressions, engagements, spend, and CPA.
You can see results for your conversion events by selecting "Customize Metrics".
Then, scroll to the "Conversions" section of customizable metrics, and select the conversion event types you want to view.
These analytics are also available via a downloadable .csv file under "Export Data" within Ads Manager.
The campaign dashboard will show conversions by conversion type. For example, if you're interested in tracking two different types of purchases, you may want to set one up as “purchase” tag and the other as a “custom” tag to report on the two separately.
Otherwise, the downloadable .csv offers an option to break out conversions by conversion event name. Post-view and post-engagement conversions are also broken out separately. To do this, select "Website Conversions by tag" when exporting your metrics.
