The following are several search engine characteristics from the Search Engine Watch's Web page. It provides a summary of important factors and features that can affect how a site is indexed. The larger the directory of a search engine is, the more likely pages from your web site will be included. Search engine size is determined by the number of pages it indexes in a day. The more it can crawl, the more likely it can maintain a fresh index.
Freshness defines the age of listings.
Submitted Pages Pages will appear faster if they are submitted directly to the search engine. The amount of time varies from the time the page is submitted until it is actually indexed. This is closely related to non-submitted pages. It indicates how many pages beyond the submitted page a search engine will gather. Frames Support Not all search engines follow frame links.
