Conversion tracking for websites enables you to measure your return on investment by tracking the actions users take after viewing or engaging with your ads on Twitter. Twitter’s conversion tracking lets you attribute conversions beyond last link click, to include actions driven by all types of ad engagements (like link clicks, Retweets, or likes) and impressions.
Twitter’s conversion tracking for websites includes powerful capabilities to let you track conversions cross-device. For example, website conversions from users who view your Promoted Tweet on their mobile device, then convert on their home computer, can be attributed to your campaign performance. Advertisers that completely integrate the Twitter Universal Website Tag across all their site pages give Twitter more touch points with their site visitors and increase the likelihood that Twitter can report accurate cross-device conversions.
