Twitter also has lots of valuable content that is being indexed by Google. The search box in Twitter is intended to find friends by name, email and phone number - currently there isn’t a site search.

Twitter Search

The Twitter site search used by the toolbar button just uses Google.com

Update: Now uses Google Blog Search for even fresher and more relevant results

You can search by:-

• Entering a value in the box and hitting the Twitter button
• Selecting text in your browser and hitting the Twitter button
• For multiple searches you can switch to using Twitter for your default search

It should be noted I chose not to use Google Custom Search because I wanted as many results as possible, and items on Twitter don’t generate authority.
This isn’t monetized in any way.

Twitter RSS Friends Feed

When you first install the button, you will be asked to enter a number. This number can be grabbed from the RSS feed of your home page.

To see what your friends are chatting about, just click the drop down box

Add Twitter to your Google Toolbar

It should be noted that this will only work with the Google Toolbar for IE, or the beta version Google Toolbar for Firefox
