If you can't tell, assume it's an ad. Think about who is giving you advice and what their knowledge is based on. Don't confuse form with substance as a guide to reliability. The best looking sites aren't necessarily the most accurate or the most useful. Evaluate advice by its relevance to your tastes.
People are different.
Look to the Internet especially for finding specialized, detailed, time sensitive, and international travel information. Don't limit your Internet travel research to travel sites on the World Wide Web. Some of the most useful online travel resources aren't on the Web, or are on Web sites that aren't specifically for travelers. You can get lots of useful travel information through Usenet newsgroups and e-mail, or by using the Internet to locate offline resources.
