It was a very important space for researchers - who, curiously, Twitter has opened its history of tweets - who wanted to analyze the advertising behavior of any account, the ads they had placed, what they had invested ... and what could be used, for For example, to find out the spending of political parties and their related accounts on advertisements when an electoral appointment was approaching.
However, the Twitter Advertising Transparency Center is no longer available. The company closed it - without making any announcement - on January 25. According to the social network, given that Twitter banned political advertising in November 2019 , and given that the review criteria for any advertisement purchased on the platform have been strengthened, "the Transparency Center has lost its original value."
The company now refers, "to maintain the same levels of transparency", to the address Business.Twitter.com , where you can learn more and download a history of political ads that were placed on the social network before they were banned. It ensures that users who want to know more about the advertisements that were shown to them can download this information by clicking on the account settings options, on the Settings and Privacy tab.
However, Twitter provides data from May 24, 2018 to November 22, 2019 (when the ban went into effect) but does not provide information prior to that date.
At least you can access some information, but anyway, keep in mind that the Advertising Transparency Center was not only used for political purposes . It could also be used by a brand when planning its campaigns and seeing how its competitors had used advertising on the social network. In this case, that historical information that might be useful to you will no longer be available.
Twitter is not the only social network that had an Advertising Transparency Center. Facebook also owns it, and in this case the social network does allow anyone to know all the advertising that any company has active - or had in the past - and that information can be accessed directly from its Page.
