SEARCH RESULTS Link Passport enables businesses to target customers searching for specific products and services. Our unique automated bidding system allows advertisers to bid on keywords that relate to their site. An important benefit Link Passport offers is the listings at the top of the results page. These are advertisers who bid on the keywords. The highest bidder appears first and the remaining follow according to their declining bid amount. The sites listed first are those with the most drive to be associated with a given search keyword or phrase. This type of model produces the most relevant results for businesses and consumers alike.
