How do I help C|ON|TEXT recognize which parts of the page contain relevant content?

Usually every page of your site contains parts that are not relevant for the topic of that page. For example, contact information usually found in the page footer or menu found on all site pages are probably not relevant for the page topic. Because C|ON|TEXT doesn't have human capabilities to analyze, existance of irrelevant content on the page might confuse the system so it thinks the page topic is different. That's why it's a good idea to point out to the system which parts of the page contain the relevant content.

There are several widespread examples of where you'd want to use this option. For example, if you're showing ads on a forum, you'd probably want only posts contents to be used as relevant, while removing parts with the poster's information, their signup date or their location etc. Or, if you're showing ads on a news site or blog, you'll probably want to remove text from the "related news" section. Titles and descriptions of related news are probably not exactly the same topic as the current page, so the ads the system will select having taken that text into account could be wrong.

To point out to the system which parts of the page contain relevant text, you have to enclose relevant sections in HTML comments with special content. C|ON|TEXT will recognize these comments as boundaries inside which the relevant text resides. Here is an example:

<HTML> <HEAD> <TITLE>Sample page</TITLE> </HEAD> <BODY> <P>This text is not relevant for the page topic</P> <!-- C-ON-TEXT_CONTENT_START --> <DIV>This text IS RELEVANT for the page topic</DIV> <!-- C-ON-TEXT_CONTENT_END --> <DIV>This text is not relevant for the page topic</DIV> <P> <!-- C-ON-TEXT_CONTENT_START --> This text IS ALSO RELEVANT for the page topic <!-- C-ON-TEXT_CONTENT_END --> </P> </BODY> </HTML>

As you can see in the example, relevant content is enclosed inside comments C-ON-TEXT_CONTENT_END for start and C-ON-TEXT_CONTENT_END for end of the section. If C|ON|TEXT finds one or more such sections on the page, it will ignore all the text outside of these sections. If there are no such sections on the page, the system will consider entire page content to be relevant.
