There is a good chance crawlers are looking for Twitter handles while they are out and about. We already know the search engines utilize social information and signals in their index. For example, you can see this information in Google’s “Realtime” vertical. If you are interested in seeing a live example check out this realtime feed of #smx.
Of particular interest today, and the reason I write this blog post, I had Google actually suggest a URL to me today inside the Google Suggest portion of the Google Toolbar. The URL that was suggested was one Google claimed was on the topic I was typing in the box and was a URL shared by one of the handles I am following on Twitter.
I tried to grab a screen shot of this Google Suggest feature in action, but I was too late. It was removed before I got the chance. Regardless, the social side of the web is blending rapidly with regular search. Make sure you have your bases covered. Utilize social with your SEO efforts.
And make sure you have your Twitter accounts available for the crawlers. Even if it’s only the spam bots.
