Advertisements that appear in newspapers and their Web sites reinforce confidence in products and services, Google research has revealed.

A study commissioned by Google, conducted by Clark, Martire & Bartolomeo shows that consumers trust ads appearing in newspapers, and many times look at both newspapers and the Internet to evaluate and make purchases, the Newspaper Association of America announced Monday.

Two-thirds (67 percent) of people who do research on products and services after seeing ads for them in newspapers go online to learn more, while 70 percent of that group end up buying the product or service after doing more research, according to the NAA. Meanwhile, in the past month, almost 30 percent of newspaper readers who use the Internet went online to research at least one product they saw in the newspaper, the research showed.

Other highlights of the study:

• 42 percent of newspaper readers who use the Internet bought at least one product they saw in the newspaper in the last month
• 44 percent researched at least one product they saw in the newspaper
• 56 percent bought or researched at least one product they saw in the newspaper in the past month
