File Types on search Engines. Which are indexed?




As an SEO consultant you must know what other channels and search options and positions your site can rank on different types of SERP.

Google can let you restrict your searches to only certain file types. This can be very helpful if you're looking specifically for file types, such as PowerPoint, (ppt) Word, (doc) or Adobe PDF.
To restrict your search to a specific file type, use the filetype: command. For example, try searching for:
bad hotel filetype:ppt

Users may also use the Google Advanced Search and restrict their searches only on specific file types.

http://www.google.ca/advanced_search 

You can use this same syntax with Google Desktop.
To search for that forgotten widget report, try:
widget report filetype:doc

Google can index the content of most types of pages and files.
The most common file types it indexes include:


  • Adobe Flash (.swf)
  • Adobe Portable Document Format (.pdf)
  • Adobe PostScript (.ps)
  • Autodesk Design Web Format (.dwf)
  • Google Earth (.kml, .kmz)
  • GPS eXchange Format (.gpx)
  • Hancom Hanword (.hwp)
  • HTML (.htm, .html, other file extensions)
  • Microsoft Excel (.xls, .xlsx)
  • Microsoft PowerPoint (.ppt, .pptx)
  • Microsoft Word (.doc, .docx)
  • OpenOffice presentation (.odp)
  • OpenOffice spreadsheet (.ods)
  • OpenOffice text (.odt)
  • Rich Text Format (.rtf, .wri)
  • Scalable Vector Graphics (.svg)
  • TeX/LaTeX (.tex)
  • Text (.txt, .text, other file extensions), including source code in common programming languages:
  • Basic source code (.bas)
  • C/C++ source code (.c, .cc, .cpp, .cxx, .h, .hpp)
  • C# source code (.cs)
  • Java source code (.java)
  • Perl source code (.pl)
  • Python source code (.py)
  • Wireless Markup Language (.wml, .wap)
  • XML (.xml)
  • When you use the filetype: operator in a Google search (for example, filetype:xml galway, Google searches for files with the .xml extension, not for files of file type XML.





Not all URLs or pages have the .html file extension. Some pages (like http://www.google.com) have no extension at all, and some have an extension that doesn't match their file type. Limiting your search to a specific file type will return pages with that file extension, and may return fewer relevant results.
