Pretty sure Twitter has an ad metrics problem too. As I wrote last year:
> When I ran a Twitter Ads campaign for one of my clients, within two days I noticed that Google Analytics was reporting nearly 100% fewer visitors from the campaign than Twitter was reporting clicks. That is, if Twitter counted (and charged for) 100 clicks, Google Analytics showed fewer than 5 visitors from the campaign.
> The support team at Twitter Ads told me they are legitimate clicks, but people are probably clicking the image in the tweet to expand the tweet or image, not expecting it to take them to a different site. As soon as they realize they’ve just clicked an outgoing link, they go back or close the tab before our site and Google Analytics script even has time to load.
