The user question in this particular video says:

Some people are under the impression that blogs are good for SEO only if they’re updated frequently. How much does frequency play into PageRank for blogs & other dynamic sites? Isn’t the content more important than the simple # of posts per day/week?

Matt’s response is that it is indeed much more important to have quality content, but frequency can be a nice thing to have for the users.

Essentially, if you post more frequently, people have more of a reason to keep coming back. That can be good for page views. However, as Matt says…

“Whenever you’re thinking about search engines, it’s much, much, much more important to think about the quality of your content. For example, on my blog, I don’t post every day. Sometimes I don’t post every week. But I try to make sure that each post has something useful about it…”

Matt implies that you’ll be better off in terms of search, if you wait until you can deliver some value to a post, rather than just crank stuff out that isn’t that much different than stuff that’s already out there. This strategy is likely to attract a lot more links, he says.

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.
