Want a Googler to come and speak at your conference or search engine optimization event? Google has a formal request mechanism to invite speakers from Google.

Check the Google Speaker Request Form. It lets you specify location, theme and date of your event. Tell them about your organization, sponsors and if any Googler has ever spoken at your event in the past. You can speak out why do you want Google to participate and even request a particular Google representative (looking for Matt Cutts?). Inform them about press coverage, any previous Googler you have contacted, type of audience and list of other speakers. Remember to supply contact details.

Now you can use this official form to directly contact Google and get a Googler to speak at your event and gain publicity.
