Search Tips: Searching by file type

In my article on SEO for PDFs, you learned how to restrict Google search results to PDFs by adding the "filetype:pdf" parameter. Here’s a few other file types you can search by:

• filetype:doc (Microsoft Word)
• filetype:xls (Microsoft Excel)
• filetype:ppt (Microsoft PowerPoint)

So if you're looking for an Excel loan calculator, you can cut through the search clutter and go straight to the files by entering:
loan calculator filetype:xls

Or if you had to find PowerPoint presentations on sea turtles, you could enter:
sea turtle filetype:ppt

There's a lot of sea turtle presentations out there...
