The fee structure is both a filter against superfluous submissions and a revenue generator. Typically, the fee covers an annual subscription for one webpage, which will automatically be catalogued on a regular basis. However, some companies are experimenting with non-subscription based fee structures where purchased listings are displayed permanently. A per-click fee may also apply. Each search engine is different. Some sites allow only paid inclusion, although these have had little success. More frequently, many search engines, like Yahoo!,[19] mix paid inclusion (per-page and per-click fee) with results from web crawling. Others, like Google (and as of 2006,[20][21]), do not let webmasters pay to be in their search engine listing (advertisements are shown separately and labeled as such).
