The Center for Countering Digital Hate found that people searching for information on abortion in "trigger states" are likely to be served with information about fake clinics that don't offer abortions.
There are laws on the books in some states that would criminalize abortion if the Supreme Court strikes down the law. A draft opinion from the Supreme Court was leaked in May.
In question are Arkansas, Idaho, Kentucky, Louisiana, Mississippi, Missouri, North Dakota, South Dakota, Tennessee, Utah, Texas, Oklahoma, and Wyoming.
For its report, London-based CCDH ran searches from each of the 13 states using a browser extension that allows people to set their computers to different locations.
When key terms like "abortion clinic near me" and "abortion pill" were entered, the first page of the search results were displayed.
Some users were directed to anti-abortion fake clinics.
A return rate of 37% was found on the 26 fake clinics that were directed to by 26 out of 70 results on the search engine.
The first three locations were used by the CCDH. The nonprofit is not the first to report on the issue of anti- abortion clinics showing up in search results.
In May, the British Broadcasting Corporation reported that it had found misleading adverts high up in the search results, which appeared to be clinics offering abortions, but were actually anti-abortion centers.
One woman said she went to a clinic that offered a free abortion consultation, but was given misinformation about the procedure, including claims that it was linked to infertility and breast cancer.
Almost 30% of the ads on the top of the search results were for fake clinics.
When it looked at the websites of the fake clinics, it found misinformation. The claims that "suicidal impulses" were common after abortions were included.
"We work to make high-quality information easily accessible, particularly on critical health topics, across our products," a spokesman for the search engine company told Insider.
"Any organization that wants to advertise to people looking for information about abortion services must be certified and show in-ad disclosures that clearly state whether they do or do not offer abortions," it said.
The company was always looking at ways to improve its results to help people find what they're looking for or understand if what they're looking for isn't available, according to the spokesman.
The placement of anti- abortion ads at the top of the results pages was still a problem, despite the fact that they were labeled with a label stating "does not provide abortions."
"When people search for information or services relating to their sexual and reproductive health, Google is sending them to sites that users expect to contain robust, scientific, evidence-driven healthcare information - but they actually contain ideologically-driven opinion and misinformation," the chief executive of the Center for Disease Control and
