A few years back Google launched the program Google Guarantee aiming to help people to find reputable local businesses that offer in-home services. Eligible advertisers are shown on the top of search engines when people search for related services. Advertisers are charged only when a valid lead comes through. It not only can help users to easily connect with trustworthy service providers but also helps local service providers to find qualified leads. Now that the Google Guarantee program was a huge success, Google has introduced the Google Screened program to professional services such as lawyers, financial planners, and realtors.
