The company said they would only be used in place of some URLs, mainly ones that don’t give the added context of a link the way that breadcrumbs do. Interestingly, there seems to be an incentive for those who go the breadcrumb route because of the multiple links that you just don’t get with regular search results.

Google’s move was generally well received. For example, a commenter going by the handle Stupidscript said, “It’s definitely a good time to start wrapping your head around the notion of ‘providing context’, because the web is heading into its “semantic” period … where each link will be more or less valuable based on its relationships with and context to information found behind other links.”

Google’s use of breadcrumbs in search results is the focus of a recently submitted question to the Google Webmaster Central team. The question was, “Google is showing breadcrumb URLs in SERPs now. Does the kind of delimiter matter? Is there any best practice? What character to use is best? > or | or / or???” Google’s Matt Cutts responded:

Matt says you should have a set of delimited links on your site that accurately reflect your site’s hierarchy. He also notes, however, that it is still in the “early days” for breadcrumbs.

“Think about the situation with sitelinks,” he says. “Whenever we started out with sitelinks, it took a while before…for example, we added the ability in Google Webmaster Tools where you could remove a sitelink that you didn’t like or that you thought was bad. So we started out, and we did a lot of experiments, and we’ve changed the way that sitelinks look several times. And we have different types of sitelinks (within a page, and the standard ones you’re familiar with). So we’ve iterated over time.”

In this same way, he says, Google is in the early stage with breadcrumbs and he has seen different experiments with them. For example, there have been prototypes where the breadcrumbs were in the rich snippet gray line, above the regular snippet. “Having it in the URL is kind of nice, but it could still change over time,” he says.

He says the best advice he can give is to make sure you have a set of delimited links that accurately reflect your site’s hierarchy, and that will give you the best chance of getting breadcrumbs to show up in Google, but Google will continue to work on ways to improve breadcrumbs. He says any new announcements about it will likely be made on the Google Webmaster blog.

While Matt doesn’t exactly lean toward one way or another with regards to which character to use as asked about in the submitted question, all of the examples I have seen highlighted show the “>” used. That includes examples from Google’s original announcement on the inclusion of breadcrumbs (if you see other ways, please point them out in the comments). Based on that, if I were going to choose one, I’d go with that.

“One of the great things about working at Google is that we get to take advantage of an enormous amount of computing power to do some really cool things,” says Patrick Chapman of Google’s Search Quality Team. “One idea we tried out was to let webmasters know about their potentially hackable websites. The initial effort was successful enough that we thought we would take it one step further by expanding our efforts to cover other types of web applications—for example, more content management systems (CMSs), forum/bulletin-board applications, stat-trackers, and so on.”

“This time, however, our goal is not just to isolate vulnerable or hackable software packages, but to also notify webmasters about newer versions of the software packages or plugins they’re running on their website,” he continues. “For example, there might be a Drupal module or Joomla extension update available but some folks might not have upgraded.”

One way Google identifies sites that need to be notified is by parsing source code of web pages that it crawls. Content management systems usually include generator meta tags that specify the version number. This helps Google figure out when sites aren’t running the latest version.

The company is encouraging developers to use such generator meta tags in their software if they are not already doing so. This, along with Google’s efforts, should theoretically keep their users using the most recent versions. That is Google’s goal, anyway.

Google says they will begin sending out notifications soon, but doesn’t give a more specific time. Do you think this is a good idea?
