Google don't read images but is it Read PDF File ?
If you have a web page that has simply been converted to a PDF and upload on various sites, wouldn’t seach engines consider that possibly duplicated content? Yes ,Question really is, if you put a PDF online, should you remove the non-pdf version if it exists?
Google is able to read text from PDF, so that might be counted as duplicated content. On the other hand, if you think about it, if you don’t go overboard, it should be fine. For example, if you only have one pdf and non pdf, you don’t need to remove it. Of course, if you want a complete unique in term of content in the PDF, you can remove the non-pdf version.
John Mueller: In general we index PDF files like we would like normal other pages on a website. What probably will happen with PDFs is that we don’t much refresh them as quickly as normal HTML pages because we assume that the PDF files stay stable. But that doesn’t sound like your problem. With regards to the indexing of PDF files if we see links to those pages we will try to index those pages to get them into the search results.
