Google, Bing, Yahoo, and other commercial search engines index your PDF, Word, Excel, and PowerPoint files and the download pages that link to your files.  Follow these best practices for optimizing PDFs and native files for commercial search engines.


Add the title that appears in the document to the title field in file properties.  Commercial search engines will display the title in search results.


Create a unique, meaningful description of the content that is no longer than 150 characters and add the description to the "Subject" field in "File Properties."  Include terms used in the document. 

To save space, descriptions may be written as phrases instead of complete sentences. 

  • Information on…
  • Includes…

Commercial search engines may display the description in search results.


Use the same titles and descriptions on your download page.  See requirements for download pages.

Note: the search engine indexes download pages but not the PDFs and native files linked on download pages.
