The service provides categorization information for web content at the page level. It represents topical context for content located at a specific URL on a website with the goal of linking ads to relevant content and increasing exposure to users who show an interest in the topic. By targeting contextual classifications at the page level, the service seeks to help advertisers identify individual pages of interest to their prospective customers rather than choosing overall websites, which may cover a range of topics.
API methods support submission of a page URL to be classified. The API returns content parameters, including length and time to load, along with up to five contextual "channels" where the content fits best. The advertiser interested in those channels can then decide which specific pages to target with its promotional messaging.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
