Google has launched a couple of new Labs features for Webmaster Tools. One is "malware details" and the other is "fetch as googlebot."

Google is providing snippets of code from pages it considers malware, in order to help webmasters eliminate the malware on their sites quickly.

Hulu has added a couple of new features to Hulu Labs. These are Hulu Desktop for Linux and Hulu Publisher Tools.

Matt Cutts has appeared in yet another Google Webmaster Video, and this time he has a whiteboard with him so he can illustrate what he’s talking about. What he’s talking about this time are uncrawled URLs in search results.

Cutts says Google gets a lot of complaints from webmasters who say the search engine is violating their robots.txt files, with which they intend to keep Google from crawling certain pages. Sometimes those URLs still end up in search results.

Google has released a new product called the Google Docs Viewer. This is a way to display PDFs, Powerpoints and TIFF documents directly in a web browser without requiring a download.

Google has made some changes to the way Webmaster Tools users verify their websites.

Before, the user’s verification meta tag was based (partially) on the email address of their Google account, which meant that if they changed the email address in their account settings, their meta tags would also change, and they’d become unverified for any sites that used the old tag. Google has made a new version of the verification meta tag, which is unrelated to the email address to prevent this from happening.

While Google’s Matt Cutts has certainly provided a wealth of helpful tips via the company’s Webmaster Central YouTube channel, he is not the only one to do so.

Google has introduced what they call "Web Elements," which let users add their favorite Google products to their website. The company spins it as a way for AdSense publishers to "spice up their site" and help increase their revenue. This was first announced back at the Google Developer Conference.

Google has made some recommendations for "best practices" for sites that allow users to create their own sites. They give the examples of their own Google Sites and Blogger. So in other words, if you run some type of site that allows users to make their own pages, you may want to pay attention.

Google wants webmasters who offer video content to be able to get their videos displayed in search results more easily. The company has announced that that it now supports Facebook Share and Yahoo SearchMonkey RDFa, which are both markup formats that allow webmasters to specify information that is important to video indexing.

One thing that Google is pretty good at is providing resources for webmasters to learn from. The regular videos from Matt Cutts in which he answers user-submitted questions are no different. It just happens to be this very topic that is addressed in the latest upload.

Question: Whenever Google detects a violation of its Webmaster Guidelines, can we expect a feature to be added in Google Webmaster Central where it could help the webmasters learn what the issue was?

Google has introduced some new features to Google Sites, the company’s web site creation and publishing app. The new features were made to make it easier for users to copy their site, and use more options to search and announce updates.

Google Sites now allows users to copy entire sites. You can do this by simply going to "Manage Site," then "General," and "Copy Site."

Last month Google spoke about an initiative it was kicking off to call upon webmasters to help make the web faster. Larry Page once said he envisioned a web that could be surfed as easily as flipping through the pages of a magazine. This initiative is kind of an extension of that way of thinking.

There has been a lot of talk about the DiggBar and its handling of URLs this week, after the company implemented some changes in its service. To clear the air, Digg has addressed the situation.

Digg CEO Jay Adelson issued the following statement on Digg the Blog:

Google has released an update to Webmaster Tools, with the code name "Summer Shine." The update comes with several new features.

The first new feature is that the site selector now lists all verified sites that the user owns. It also allows the user to search as they type.

Google’s Matt Cutts frequently posts useful tips for webmasters on the Google Webmaster Central YouTube channel. The short clips generally offer valuable nuggets of info that can have an impact on your site’s performance in Google.

Microsoft announced the Bing Toolbox today, which is a new portal for webmasters, publishers, developers, and advertisers. Basically it is a resource for finding useful Bing-related tools. Here’s the official description:

The Toolbox is an organized set of tools for the entire Bing community. It’s a one-stop portal to all of the services you need to drive traffic and increase engagement with your site and applications.

Google has been working on updates to how it uses sitemaps. Considering research highlighted in this study (pdf), which showed how search engines find new and changed content faster with sitemaps, webmasters should take note.

As you may have read about by now, Google’s Matt Cutts participated in a fairly lengthy Q&A session at SMX Advanced in Seattle. One interesting question that Matt got was about how webmasters should deal with display:none and AJAX without being penalized by Google.

Cutts recommends making sure that whenever you write your own mouseover code that you don’t roll your own custom solution, which he says might do some really weird things that nobody else has done before.

Web Accessibility organization WebAIM has posted results from an interesting survey on the use of screen readers. Webmasters should pay attention to this, as accessibility is an important part of your online presence, but is often ignored or overlooked. Just ask Target, who settled an accessibility lawsuit last year for $6 million.

Google has introduced a new Sitemap Generator for webmasters to help them create better sitemap files. Google had previously introduced one back in 2005, and watched many other people make their own, but this one is different they say.

Google said today that it is introducing a new look to its Webmaster Help Group.
