Chitika

In December 2005, some publishers reported a reduction in revenue after auditing between 25%-90%.^[8][9]

In 2010, Chitika removed their ads from thousands of websites. The company stated that the sites they had been doing business with were all suddenly placed under "Pending Review" or "Pending Further Review" status. This meant the company would no longer show ads on the sites. Many dropped the advertising service.^[10]

On March 16, 2011, the Federal Trade Commission (FTC) appeared before the United States Senate Commerce Committee and announced its first behavioral advertising case, filed against Chitika for use of a deceptive opt-out mechanism. According to the FTC, Chitika's cookies that opt users out of behavioral tracking were expiring in ten days rather than the stated ten years.^[11] A settlement was reached under which Chitika was forbidden from making misleading statements about the extent of data collection about consumers and the extent to which consumers can control the use of their data. Further, the settlement required that Chitika link all its advertising to an effective opt-out mechanism in future. It has been commented that, “this requirement of a hyperlink embedded in online advertisements is a good indicator of the type of Do Not Track mechanism that will be acceptable to the FTC if “Do Not Track” becomes mandatory.”^[12] According to a press release by the company, their opt-out cookies have been set to ten days since March 2010 when the FTC began their investigation.^[13] Chitika subsequently claimed to have made only a total of fifty-five cents from the ten-day opt-out expiration.^[14]

In 2017, Chitika shocked its publishers by changing the minimum payout from $10 to $50. It affected many existing publishers who joined Chitika for its lower payout option. Publishers who cross $50 are banned from the network.

On April 17, 2019, Chitika wrote to publishers advising them of their immediate cessation of business. The email advised publishers to remove all Chitika code from their website. The email further advised publishers that they would not be paid for impressions or clicks occurring since March 1, 2019.
