Some tips
Finding icons: Want to find icons to put next to your details? Here is a special Google search (opens in a new tab) that will help you find small icons. Just type the name of the services you're looking for in the search box, and you'll get icons size images you can copy and add to your signature.
More than one signature : Note that you can set up more then one signature if you have more than one email address associated with your Gmail account.
Track website traffic: If you have a website, you can monitor how many people get to it from the link in your signature. To do that, you need to tag the link, so that Google analytics (if that's your analytics application) will recognize the visit source. For example – to tag the link in my signature, I could add this tag:
http://www.productivewise.com?utm_source=MailSignature
To monitor clicks to your site, just replace the base address in the example above, and add the link to your signature.
