Some savvy webmasters were inspecting the HTML markup behind the last Google Webmaster Blog post and noticed the markup used on the posted by John Mueller hyperlink had a bit of extra code for rel=agent. Here is a screen shot of the code:
Paul Shaprio asked about it on Twitter after noticing it, saying “Weird, probably insignificant observation… JohnMu is tagged with ?rel=agent.” Indeed.
Often Googlers, especially on the webmaster blog, add markup to see if we are looking. It is Google humor, that is how Googlers have fun.
John replied:
Yea right, a typo. 🙂
As you know, Google has destroyed authorship so it would have said rel=author but John changed it to rel=agent to mess with us.
Love this stuff.
Forum discussion at Twitter.
Update: Now John changed it to google.com/+johnmueller?rel=AUTHOR
