We increasingly utilize internet search engines such as Google, principally through the purchase of travel related keywords, to generate traffic to our websites. Search engines, including Google, frequently update and change the logic that determines the placement and display of results of a user’s search, such that the purchased or algorithmic placement of links to our websites can be negatively affected. In addition, a significant amount of traffic is directed to our websites through our participation in pay-per-click and display advertising campaigns on search engines, including Google, travel metasearch engines, including Kayak, and internet media properties, including TripAdvisor. Pricing and operating dynamics for these traffic sources can experience rapid change, both technically and competitively. Moreover, a search or metasearch engine could, for competitive or other purposes, alter its search algorithms or results causing a website to place lower in search query results. If a major search engine changes its algorithms or results in a manner that negatively affects the search engine ranking, paid or unpaid, of our websites or that of our third-party distribution partners, or if competitive dynamics impact the costs or effectiveness of search engine optimization, search engine marketing or other traffic-generating arrangements in a negative manner, our business and financial performance would be adversely affected, potentially to a material extent.
