How many PDF files are present on the Internet ?
Have you ever got this doubt.
I have got this doubt and Google answered me. But the answer is not through a direct question.You can not ask Google directly "number of files on Internet" . Even if returns some answer it may be a old number.
Instead of searching directly for the number of PDF files, we can use an operator search in Google.
enter "filetype:pdf" in Google search to find the number of PDFs available online.

You can try this for other file types also like Jpeg,png images; Ppts; Google earth files etc.
So here are some statistics of number of files indexed on Google
- PPT -10,100,000 files
- PNG -10,800,000 files
- JPEG -1,310,000 files
- PDF -723,000,000 files
- DOC -83,600,000 files
- TXT -40,500,000 files
- XLS -15,300,000 files
This is just one of the usage of search operators in Google.
Its awesome. Just typing 2 words, we can see files on internet..!! But one question that there are many websites which are not indexed in Google Search Engine. Then files which are uploaded there, can Google include them also in the total list?
ReplyDeleteGood point.......Google may not index the files under a website which is not indexed by google.
ReplyDeleteanother case is the webmaster(owner) of a website may also tell google not to index some unwanted files(using rel=nofollow logic)..and finally google will also skip the files which are encrypted(say a file uploaded by you into dropbox or your e-mail)...so here also we are missing the exact count...but the simple thing is Google will answer about the number of available files on internet
