Finally published my first Chrome Extension, which detects (or tries to at least) the Google+ profile for any website and displays a popup that pulls profile data from the public Google+ API.

Install it from the Chrome Web Store:

One of the goals I set for myself this quarter was to get more familiar with the various development platforms that we support at Google. I use a number of Chrome extensions on a regular basis, and I&...

Nice! Are there any meta tags we need to include in our sites to make them compatible?
The widget +Robert Scoble is using on his page is from, it's not the Google+ badge. The 'widgetsplus' badge relies on a global javascript variable named 'pid' to identify the Google+ profile ID. I'm really hesitant to rely on something like that given the opportunity for false positives.

Ideally, Robert should add a <link rel="me" href="" /> to his page, which will also allow things like author snippets in search ( to work.

As a secondary solution, I'll see about talking with the widgetsplus folks to use a more descriptive variable name like 'plus_id' or something.
+Will Norris does that mean every page on my site should have an <a href="[G+ url]" rel="me">...</a> link on it? I'm pretty sure only one of them does now. Is there a meta tag for pages that wouldn't normally link to a G+ profile?
+James Salsman: rel-me is used to tell that another page represent the same profile as the one linking to it.

rel-author is used to tell that a profile page represents the author of the content linking to it.

rel-publisher is a bit non-standard as far as I know - but is similar to rel-author with the difference that it tells which organization is behind/publishing the content instead.

So - in most cases you should use rel-author. Only if a page is kind of a profile page should you use rel-me.
+James Salsman: If you don't want to include an a-tag in the body of your HTML, then you can instead add a link-tag with the same rel and href to the head of your HTML.
Nice. What it can't do yet (I think), is to walk along a trail of rel=author -> rel=me local profile -> google profile So If I'm looking at a blog post that links to a profile page on the blogging platform, that links to a google profile, it won't find it. But then I'm having trouble getting Google to recognise all these trails and put content profile owners on search results.

I can't demo this at the moment without some more research, but I suspect you should be able to see this in your average page. The blogger account is probably linked to a G+ account. There might be a link on the blogger profile page. But getting all the way from a specific post to G+ doesn't happen.
Now if only Google+ badges supported profiles you could circle someone from the pageAction popup....
well, that and if the badge looked better in the popup window. I'm not a fan of the forced 1px grey border it has :-\
