Twitter Ads Transparency Center Assessment
Twitter pledges to provide public access to political ads in its “Ads Transparency Center”:
We believe that transparency is a core part of who we are. As part of our commitment to be more transparent, we’ve created a place where you can search for advertisers and see the details behind ads.
This document presents the difficulties and limitations of Twitter’s transparency effort concerning political ads.

Policies for restricted content
Twitter defines categories of prohibited and restricted content. Political content is one such category of restricted content. Twitter distinguishes two kinds of political content: “political campaigning” and “issue advertising”.
Twitter permits political advertising which includes political campaigning and issue advertising (Source).
These two categories are subject to different policies.
A political campaigning policy has been enforced from summer 2018 in the USA and policy enforcement for Australia, India, and EU Parliamentary elections began March 11th 2019. Political campaigning advertising is permitted worldwide except in the following countries: Brazil, Cyprus, France, Hungary, Latvia, Lithuania, Malaysia, Morocco, Pakistan, Portugal, South Korea, Vietnam.
Twitter Ads Transparency Center
October 24th, 2017, Twitter announced the launch of the Ads Transparency Center “in the coming weeks”. The Ads Transparency Center was effectively launched June 28th, 2018. Initially, it displayed only US federal election campaigning ads and it was extended to EU, India and Australia in February 2019.
As part of its political content policies, Twitter requires some advertisers to pass a certification process.
Policies and documentation are scattered
Statements are often duplicated in several places in exact or similar terms. All the pages do not seems to have been updated to reflect the March 2019 extension to the European Union. In particular, it is often unclear if a given statement applies to the US or worldwide and for which level of political campaigning (federal or state level; national or European) and in which cases the certification process is mandatory.
For instance, the issue ads FAQs applies worldwide, yet makes recurring references to the USA (bold ours):
Twitter’s Political Content Policy includes Issue Advocacy which applies to ads that refer to an election or a clearly identified candidate or ads that advocate for legislative issues of national importance. Note that this policy applies to promoted content related to federal, state, and local elections.
Will the issue ads policy cover other issues in the future? We are continually looking into these issues based on the U.S. political climate.
Does the policy apply to non-federal elections? Yes, all promoted political content will be considered an issue ad with a carveout for federal political content that is subject to a more stringent certification process.
The entire information regarding the list of topics that Twitter considers “legislative issues of national importance” subject to the issue advertising policy is:
Examples of legislative issues of national importance include but are not limited to: climate change, healthcare, immigration, national security, taxes. (Source).
Certification constraints are not clear outside the USA
Certification requirements are unclear outside the USA. In the help page for the certification process, we read:
As part of Twitter’s Political Content Policy and our overall commitment to transparency, we require that advertisers promoting political campaigning content go through a certification process. Note that this process only applies to advertising related to: US federal elections, US issue advocacy.
and immediately after, this contradictory reference to other countries:
Note: the certification process for Australia, India, and EU Parliamentary elections is closed.
The same ambiguity is found in the political content policy help page:
This policy applies to political content which consists of political campaigning and issue advocacy advertising.
Country-specific policies that require certification:
- United States
Advertisers can start the certification process here.
Note: the certification process for Australia, India, and EU Parliamentary elections is closed.
Political Promoted Tweets
What information is shown for political advertisers?
Once an advertiser agrees to the updated Terms of Service from their certified political ads account, the Twitter account will appear in the Ads Transparency Center under the corresponding country’s advertiser list. (Source)
If you are an advertiser that promotes issue ads you need to get certified. (Source)
Which is consistent with an announcement made February 19th, 2019:
Enforcement of this policy will begin the week commencing March 11th in these countries, after which only certified advertisers will be allowed to run political campaigning ads on our service.
However, these pages state that the obligation only holds for ads related to the European elections and not to national elections and issue advertising:
Answers below apply to Australia, EU Parliamentary elections, India, and the United States. (Source)
Political campaigning ads for EU Parliamentary Elections ONLY must meet additional eligibility requirements and apply for certification. (Source)
The old title of the help page for the certification process prior to the extension to the European Union still appears: “How to get certified as a political campaigning advertiser in the U.S.”.
No comprehensive access to political ads
As of June 17th, 2019, the Ads Transparency Center consists of:
- a search engine on Twitter’s ads;
- the list of certified advertisers for political campaigning, for the USA, the European Union, Australia and India;
- the list of certified issue advertisers for US issue advertising.
According to the Ads Transparency Center FAQs, “only ads from certified accounts per the Political Content Ads Policy are displayed in the ATC”. However, the Ads Transparency Center search bar gives access to advertiser timelines with no links to politics, such as a windshield dealer or pizzerias. The search bar does not give a mean to access the entire list of advertisers: this would require to search for all possible strings of characters.
Furthermore, from the content of the ads, it seems that the list of advertisers for political campaigning accessible through the Ads Transparency Center relates only to the European parliament elections. The Ads Transparency Center currently provides no way for researchers to access all political ads concerning national politics or issues.
Only a subset of political ads is shown
Twitter offers a wide range of advertising formats: “Promoted tweets” and “Promoted-only tweets”, “Promoted Accounts”, “Promoted Trends”, “Twitter Promote Mode”, “In-stream Videos”, “Conversational Ads”, “First View”, “Spotlight”, custom emojis… While political campaigning ads may only be promoted via the use of Promoted Tweets and In-Stream Video Ads, the issue advertising policy does not impose such a restriction. Yet currently, only Promoted Tweets appear in the Ads Transparency Center.
“In-Stream Video” political campaigning ads are thus not referenced in the Transparency Center, as well as all issue advocacy ads except Promoted Tweets. We have not been able to assess what proportion of all political ads this represents, in terms of numbers or spending.
Data cannot be downloaded
All the information provided by the Ads Transparency Center is tied to the interactive user interface. It cannot be downloaded as a file to be reused.
This means that researchers who want to conduct quantitative studies on Twitter ads first have to reverse engineer the user interface of the Ads Transparency Center. This is time consuming, requires advanced programming skills and entails potential violations of Twitter’s Developer Agreement on reverse engineering.
API is not documented
The Ads Transparency Center relies on an API to access data from Twitter. We have identified the following endpoints:
GET https://ads.twitter.com/transparency/political_advertisers.json GET https://ads.twitter.com/transparency/user_metadata.json GET https://ads.twitter.com/transparency/tweets_timeline.json GET https://ads.twitter.com/transparency/line_item_metadata.json GET https://ads.twitter.com/transparency/tweet_performance.json GET https://ads.twitter.com/transparency/data/line_item_delivered_targeting_criteria.json GET https://ads.twitter.com/transparency/data/line_item_targeted_audience.json
Unfortunately, this API is not publicly documented. This means that these endpoints can be affected by future breaking changes without notice to its external users, making any research based on it brittle.
Authorization tokens expire frequently
Having a Twitter account is not a requirement to access the Ads Transprency Center. Yet, access to the API endpoints is subject to a complex and undocumented process of temporary authorization.
POST https://api.twitter.com/1.1/guest/activate.json to request temporary “guest tokens”. Even though we could not find official documentation about these guest tokens, we observed that they need renewal after a few dozen requests before they become invalid. This makes it cumbersome to do large-scale analysis.
API returns frequent errors
We observed availability issues on the Ads Transparency Center API. An error with HTTP code 500 (Internal Server Error) is returned with body
These errors are transient (go away on retry) most of the case. However, on June 7th, for several hours we could not access the data about the targeted audience (endpoint
line_item_targeted_audience.json) of the second campaign (id
f2ajd) promoting a tweet about the EU parliamentary elections.
This could entirely be avoided if the data could be downloaded.
Poor data integrity
Twitter expresses a strong commitment to ensure public access to its promoted political content, with no time limitation, whether for political campaigning:
If you are a candidate running for a general election in supported countries you must always use your dedicated political campaigning ads account and all your Promoted Tweets will display a ‘Promoted (political) badge, disclaimer information, and show in the Ads Transparency Center indefinitely. […] All political campaigning ads targeting the US, EU, India, and Australia from non-certified accounts will be halted. (Source)
or issue advertising:
Promoted Tweets created from the dedicated issue ads account will show in the ATC indefinitely. Promoted Tweets from non-political advertisers will be available for seven days. (Source)
However, we have not seen this pledge honoured upon analysis.
Data can be removed at will by the advertiser or by Twitter
From the Ads Transparency Center FAQs, it becomes clear that data integrity is not guaranteed in any way since both the advertiser and Twitter may decide to halt the exposure in the Ads Transparency Center:
Country withheld ads will only appear in countries where the content is allowed.
If an advertiser deletes a Promoted Tweet or their Twitter @username, their tweets will no longer show in the ATC.
If an ad is reported and taken down from Twitter, it will be tombstoned in ATC within approximately 24 hours. If the account was suspended, tweets will not be shown in the ATC. The same applies to deleted users and tweets.
If the @username no longer exists, all associated ads will no longer appear in the ATC.
In case of suspended content, Twitter states that the reason for suspension is made public:
When you search for an advertiser, you’ll be able to see all Promoted Tweets that are currently running on Twitter, including Promoted-only Tweets, or if a Promoted Tweet was suspended and why.
Unexplained data removal
We are monitoring the content displayed in the Ads Transparency Center about European certified political advertisers, since June 7th, 2019.
We observed that among the 505 tweets classified as political advertising about the EU parliamentary election available on the Ads Transparency Center on June 11th 2019, 92 were removed by June 12th 2019. However, most of these tweets were still shown on Twitter as of June 19th, indicating that these removals were not justified by the content policies.
Here are some of the tweets that were removed:
