As a follow-up to my recent post about how user reports of webspam and paid links help improve Google's search results for millions of users, I wanted to highlight one of the most essential parts of Google Webmaster Central: our Webmaster Help Group. With over 37,000 members in our English group and support in 15 other languages, the group is the place to get your questions answered regarding crawling and indexing or Webmaster Tools. We're thankful for a fabulous group of Bionic Posters who have dedicated their time and energy to making the Webmaster Help Group a great place to be. When appropriate, Googlers, including myself, jump in to clarify issues or participate in the dialogue. One thing to note: we try hard to read most posts in the group, and although we may not respond to each one, your feedback and concerns help drive the features we work on. Here are a few examples:

Sitemap detailsSubmitting a Sitemap through Webmaster Tools is one way to let know Google know about what pages exist on your site. Users were quick to note that even though they submitted a Sitemap of all the pages on their site, they only found a sampling of URLs indexed through a site: search. In response, the Webmaster Tools team created a Sitemaps details page to better tell you how your Sitemap was processed. You can read a refresher about the Sitemaps details page in Jonathan's blog post.

Contextual help
One request we received early on with Webmaster Tools was for better documentation on the data displayed. We saw several questions about meta description and title tag issues using our Content Analysis tool, which led us to beef up our documentation on that page and link to that Help Center article directly from that page. Similarly, we discovered that users needed clarification on the distinction between "top search queries" and "top clicked queries" and how the data can be used. We added an expandable section entitled "How do I use this data?" and placed contextual help information across Webmaster Tools to explain what each feature is and where to get more information about it.

Blog posts
The Webmaster Help Group is also a way for us to keep a pulse on what overarching questions are on the minds of webmasters so we can address some of those concerns through this blog. Whether it's how to submit a reconsideration request using Webmaster Tools, deal with duplicate content, move a site, or design for accessibility, we're always open to hearing more about your concerns in the Group. Which reminds me...

It's time for more Popular Picks!
Last year, we devoted two weeks to soliciting and answering five of your most pressing webmaster-related questions. These Popular Picks covered the following topics:

• Susan outlined a few ways to ensure your site is being indexed by Google.
• John answered some questions about spam reporting and reconsideration requests.
• John also wrote a blog post that is a great resource for meta tags.
• Wysz provided some clarification on hidden text.
• Matt detailed appropriate uses of the nofollow tag.

Seeing as this was a well-received initiative, I'm happy to announce that we're going to do it again. Head on over to this thread to ask your webmaster-related questions. See you there!

In the fight against badware, protecting Google users by showing warnings before they visit dangerous sites is only a small piece of the puzzle. It's even more important to help webmasters protect their own users, and we've been working on this with StopBadware.org. A few months ago we took the first step and integrated malware notifications into webmaster tools. I'm pleased to announce that we are now including more detailed information in these notifications, and are also sending them to webmasters via email.

Webmaster tools notifications
Now instead of simply informing webmasters that their sites have been flagged and suggesting next steps, we're also showing example URLs that we've determined to be dangerous. This can be helpful when the malicious content is hard to find. For example, a common occurrence with compromised sites is the insertion of a 1-pixel iframe causing the automatic download of badware from another site. By providing example URLs, webmasters are one step closer to diagnosing the problem and ultimately re-securing their sites.

Email notifications
In addition to notifying webmaster tools users, we've also begun sending email notifications to some of the webmasters of sites that we flag for badware. We don't have a perfect process for determining a webmaster's email address, so for now we're sending the notifications to likely webmaster aliases for the domain in question (e.g., webmaster@, admin@, etc). We considered using whois records, but these often contain contact information for the hosting provider or registrar, and you can guess what might happen if a web host learned that one of its client sites was distributing badware. We're planning to allow webmasters to provide a preferred email address for notifications through webmaster tools, so look for this change in the future.
