and National Institute of Family and Life Advocates (NIFLA). A CPC may be affiliated with more than one network. US based Care Net and Heartbeat International are the world's two largest CPC networks with about 3,000 associated centers between them in the United States and abroad. Italy, for example, has more than 400 CPCs associated with Heartbeat International, the largest number outside the U.S. The largest UK organisations are CareConfidential and LIFE, while the largest Canadian one is the Canadian Association of Pregnancy Support Services (CAPSS). Human Life International, a Catholic group opposed to abortion, also runs CPCs outside the United States. Advertising methods CPCs have been criticized for deceptive advertising. Some falsely advertise abortion services, attracting clients who wish to have an abortion. In the 1980s, investigative reporters from the Arizona Republic, the San Francisco Chronicle and CBS News, among others, filed stories about CPCs attracting women by offering free pregnancy tests but then presenting them with religious arguments and scare tactics against abortion. CPCs may intentionally locate near, and look like, abortion clinics; critics have also objected to CPCs' use of rhetoric and advertising language similar to those of abortion providers, such as "Plan Your Parenthood" or a directory listing under "abortion services" or "clinics". These, they say, may mislead pregnant women seeking abortion into contacting a CPC. In particular, the advertising approach of the Pearson Foundation, which assists local groups establishing CPCs, has been criticized by some other anti-abortion groups, including Birthright International, another CPC operator. The foundation recommends that a center seek out women who want abortions through "neutral" advertising, and refuse to answer questions that would reveal that they provide neither abortion services nor referrals to abortion services. Pearson, identified by some as the founder of the first CPC, said that a woman "has no right to information" that will allow her to have an abortion. In Ireland, when abortion was illegal except in circumstances where pregnancy endangered the mother's life and women often went to the United Kingdom to end their pregnancies, "rogue" CPCs, in contrast to government sponsored pregnancy centers, might falsely give the impression in their advertising that they referred women to Britain for abortions or otherwise provided information for women seeking to travel for abortion. In recent years, CPCs have also begun using the Internet as a means of advertising. Some use search engine optimization to get their websites closer to
