Google’s most recent Webmaster Central Blog post, entitled Better page titles in search results covers the basics of how page titles and descriptions (called snippets) are generated.

A few things to note:

  • Best practices dictates you write your own title tags.
  • Best practices also dictates you write your own descriptions that are concise and easy to read.
  • Algorithms may generate alternative titles:
    • Mainly used to result in a higher clickthrough rate
    • May be used if title is absent or non-descriptive
    • May be used if the same title is present on every page
    • May be used if there is only slight variation between titles
    • May be used in the place of overly long or hard-to-read titles

In the New Year, Webmasters should take note that Google has updated their Site title and description page (including an eight minute video of Matt Cutts discussing optimizing websites for Google and snippets).   This page also offers a solution for Webmasters frustrated with titles and descriptions they did not write appearing in search engine results pages (SERPs).   If you have found that your titles or descriptions appearing in SERPs are sourced from the Open Directory Project (ODP), or DMOZ, there is a solution!

The following code, inserted in the head section of your code, will tell all robots not to display information from the ODP with regard to your snippets.
