Some beginning Web masters face very simple problem - their PDF-files which are on a server, are not indexed by the searcher. For this purpose, that similar difficulties would not arise henceforth, it will be useful to explain - what PDF-documents happen also what of them can get to an index.
As already to you it became clear, not all files with expansion PDF are indexed by search cars. Searchers are ground exclusively on processing of the text information - them does not interest, in which document are the text (txt, Word, HTML, PDF - it is not important!). For this purpose, that your PDF-document would be proindeksirovan, it is necessary for you to create it in the form of the text, instead of in the form of a graphic representation. The matter is that PDF-converters, can translate text filling from vordovskogo (or any other) a format, both in the form of the text, and in the form of a picture - therefore, to begin with study the program-converter, and then watch closely, that it would compile symbols in text PDF-files, instead of in the graphic.
By sight, text and graphic PDF-documents differ nothing from each other - only in the first case, the text can be allocated and copied, and in a graphic variant, it to make any more it will not be possible.
Hence - if the searcher cannot read the text (that it is executed graphically), and, especially, it cannot it proindeksirovat.
Therefore, before hanging out PDF-files on a server, try save-Pastas - if symbols are allocated and copied in usual txt, any of searchers will not refuse what in due course to bring contents of your PDF-file in the index.
Here all is simple! :-)
Well and on the other hand, news from IT fronts come encouraging - not far off already that time, when technology OCR (Optical Character Recognition, i.e. optical character recognition) will start to be applied and in search engines. Then precisely need for the similar article will disappear on all of 100 % :-)
