Invisible Web
Typically, the invisible web is often referred to as 'deep web,' 'hidden web,' 'opaque web,' and 'private web;' and is associated with web pages that search engines cannot or will not index. In this case, web pages and documents may become 'invisible' or transparent to users and search engines.Some reasons why web pages are made to be or are invisible to search engines and users is due to the fact that new material has been added to websites, but has not yet been read by web crawler programs; no links lead to website content; or in the case of deep multi-structured directories spiders may be restricted from reaching them.
Other motives as to why invisible web pages exist or seemingly 'don't exist' is due to websites purposely excluding themselves from search engine results; and too, the fact that sites may be password protected. One more example would be that websites have programmed their website as a "Noindex" site; this communicates to spiders not to index web page(s).
In general, it is important to understand when to use specific programming to make a web page part of the invisible web; but it is also critical to realize that in order to generate traffic, higher search engine ranking and page rank, web developers should be careful when including part or their entire website in the hidden web.
