Website Propagation (a.k.a. web site propagation): virtual multiplication and dissemination of a website, it's content and/or domain name to other data bases across the world wide web.
Website propagation occurs "naturally" and mechanically.
"Natural" propagation of a website occurs via different mechanisms. One mechanism of "natural" website propagation is via search engine robots which find and index websites and storing that information on servers other than the origin of the website. A second method of "natural" website propagation is via internet users who visit and tell others about the website. The visitors computers save the url and/or cookies in temporary and sometimes permanent files.
Mechanical website propagation occurs through the direct efforts of website marketers. Website marketers post links, urls, and web pages on servers, web pages, search engines across the Internet (These are the "seeds" of a website). A last method of propagation is duplicating a website with different domain names; slight differences commonly made to duplicate websites are only in the extension (example; .com, .net ,.biz...)
The seeds of a website can be hidden from site when embedded in any part of the website such as web pages, text, images, videos or other digital assets that are addressed with a common domain name or IP address.
Website Propagator: is the mechanism of virtual multiplication of a website across the internet.
Website Propagators can be "natural" or mechanical.
"Natural" website propagators refer to virtual mechanisms that occur without the implicit purpose of increasing or multiplying. Those "natural" propagators include but are not limited to internet users who visit a website and tell others about it. Other natural propagators are search bots who search and index websites.
Mechanical website propagators intentionally duplicate websites and embed links to a website in media and on websites across the internet. Internet Marketers (web marketers) are website propagators.
