We've just released updates to several features in Webmaster Tools to provide you with more detail and more control of how your site appears in search results.

Search queries: Time does not stand still and neither should your site. With that in mind we've added a "Change" column next to the impressions, clicks, clickthrough rate (CTR) and position columns, making it easier to identify trends for each of these important metrics. The change column is tied to the date range you specify, which should help when you're trying to pinpoint when a particular change occurred.



Each query listed in Search queries now links to a query details page which includes a graph of impressions and clicks for that specific query, providing a quick visual of its performance in the search results over time. Below the graph is a table listing of the pages returned in search results for that query, along with impressions, clicks and CTR. Each column in the table is sortable, offering a quick way to re-sort the data based on what's most interesting to you. If you'd rather use your own favorite tool to slice and dice the data you can use the "Download this table" link to export all the information from the main Search queries page or from each individual query details page.



Better Parameter Handling: We've moved this feature under its own tab in the Settings section of Webmaster Tools, and introduced a new action to manage parameters. When we introduced Parameter Handling last year, we allowed you to specify URL parameters and whether they should be ignored or not. When you choose to ignore a parameter, you are telling us that this parameter has no impact on the displayed content. For example, consider a session id parameter, like “sid” in the following URLs:

http://example.com/product.php?item=swedish-fish
http://example.com/product.php?item=swedish-fish&sid=1234
http://example.com/product.php?item=swedish-fish&sid=5678

Assuming that these three URLs display exactly the same product page for tasty Swedish fish candy, Google only needs to crawl and index one of them. You can simply select action “Ignore” for parameter “sid” in Webmaster Tools and Google will just crawl and index one of these URLs, avoiding duplicates.

In addition to the old functionality, you now have the ability to choose a specific value among the known values for a given URL parameter. This is important when a parameter is relevant to the content, but different values of this parameter lead to similar pages. For example, consider a sorting parameter, like “sort-by” in the following URLs:

http://example.com/shop.php?category=candy&sort-by=asc-price&page=1
http://example.com/shop.php?category=candy&sort-by=desc-price&page=1
http://example.com/shop.php?category=candy&sort-by=asc-price&page=2
http://example.com/shop.php?category=candy&sort-by=desc-price&page=2

These four URLs show products in the candy category. There are enough items in this category to fill two pages, and the products shown can be sorted by price, in ascending or descending order. Selecting action “Ignore” for parameter “sort-by” would be incorrect and could potentially limit our indexing of the site. This is because, after ignoring “sort-by”, we would consider the first two URLs equivalent and may choose to index the URL with ascending sort order. We would also consider the last two URLs equivalent and may choose to index the URL with descending sort order. In this scenario, we would be indexing the candy category inconsistently, with some candy products appearing in both of the pages selected for the index, while other candy products not appearing in either of them. The right solution comes from the new action “Use specific value” now available in Webmaster Tools. To avoid duplicates but still keep our indexing consistent, you can simply select action “Use specific value” for parameter “sort-by” and choose one of the valid values, say “asc-price”. After this, our indexing would be fully consistent, as we would focus only on the pages with products sorted by ascending price.



Messages: Some sites receive lots of messages in the Webmaster Tools Message Center. With this update we've added the ability to "star" specific messages that you deem important. There's now a separate "Starred" view where you can see all the messages that you’ve starred, making tracking and finding the most important messages for your site a breeze.



We hope these updates make Webmaster Tools even more useful for your site. Please post a comment if you have feedback on any of these updates; or if you have questions, post them in our Webmaster Help Forum.

Last October, we launched Webmaster Tools Labs and it has been a huge success. Malware Details have helped thousands of users identify pages on their site that may be infected with malicious code, and Fetch as Googlebot has given users more insight into our crawler.

Today, we're happy to announce two additional Labs features:

• Fetch as Googlebot-Mobile
• Create your Sidewiki page owner entry

Fetch as Gooblebot Mobile (developed by Ryoichi Imaizumi)

After we launched Fetch as Googlebot, many users with mobile-specific sites asked if we could provide the ability to fetch their pages as Googlebot-Mobile. We thought it was a great idea, and added it as an option to our Fetch as Googlebot feature. We have two mobile options: cHTML (primarily used for Japanese sites), and XHTML/WML.





Create your Sidewiki page owner entry (developed by Derek Prothro)

Sidewiki allows users to contribute helpful information to any webpage using a sidebar in Google Toolbar or a Chrome extension. Webmasters can create a special entry, called a page owner entry, that appears above all entries written by users.



After Sidewiki launched webmasters kept asking, "How can I put a Sidewiki page owner entry on all pages of my site quickly?" With the feature that we're introducing today, you can now create these page owner entries directly within Webmaster Tools for any site you own.



We're really happy about these new features, and hope you enjoy them as much as we do. Let us know what you think!

Seo Master present to you: 2009 has been a busy year for the App Engine team, but all along we've looked forward to Google I/O and the excitement it brings to Google's developer community. At I/O last year, App Engine was brand new and many attendees were just getting familiar with the project. Well, what a difference a year makes - this year, in addition to sharing new information about our project, we got to learn about an amazing host of App Engine projects from you, our developers!

First, the big news - we are excited to announce open signups for our Java language runtime. During Wednesday's keynote, Engineering Manager Kevin Gibbs and Product Manager Andrew Bowers demoed the combined power of App Engine and GWT, all with easy deployment from the Eclipse IDE. If you've not tried our new language yet, please head over to the Admin Console to signup, then download the SDK and get programming.

The engineers behind Google App Engine for Java presented two sessions. First, Toby Reyelts and Don Schwarz introduced the new runtime with App Engine: Now Serving Java, including details of how our Java language layer exposes the power of Google's infrastructure. Be sure to check out the interactive game they demo'd with audience participation! Digging a bit deeper, Max Ross showed us The Softer Side of Schemas - how he mapped Java Persistence Standards to App Engine's datastore.

In addition to the new Java runtime, App Engine developer Brett Slatkin previewed some eagerly anticipated functionality: offline tasks. In his talk Offline Processing on App Engine: a Look Ahead, Brett revealed the first few milestones of App Engine's plan for offline processing with our upcoming Task Queue API. Leveraging the power of a web hook (an HTTP request body and URL) as the fundamental unit of execution on the web, this new API will allow you to organize and enqueue tasks for efficient background processing. Stay tuned to the App Engine blog for this feature's launch.

The App Engine team is always eager to share information about our infrastructure and how things work under the hood. Alon Levi kicked things off Wednesday morning with From Spark Plug to Drive Train: Life of an App Engine Request, in which he showed new information about how an application's incoming requests are received, scheduled, and executed by App Engine. Ryan Barrett presented some of the theoretical, yet practical challenges faced by the App Engine team with Transactions Across Datacenters (and Other Weekend Projects). Finally, Brett Slatkin took the stage once again, with Building Scalable, Complex Apps on App Engine, to give you insights on advanced data structures and algorithms.

In addition to the App Engine team, we were thrilled to have App Engine customers and partners present about their experience with the platform:

• The Walk Score team shared their experience combining App Engine with other products in App Engine Nitty-Gritty: Scalability, Fault Tolerance, and Integrating Amazon EC2.
• Ola Bini gave a language implementor's view of our new Java runtime with JRuby and Ioke on Google App Engine for Java.
• Daniel Wilkerson presented distributed database theory in A Design for a Distributed Transaction Layer for Google App Engine.
• Guillaume Laforge from SpringSource did a rapid walkthrough of Groovy and how to write Groovy applications for App Engine with Groovy and Grails in App Engine

Last but not least, more partners joined our Developer Sandbox to share their experience building projects on Google App Engine: 3scale, Best Buy, BuddyPoke, EZAsset, Gigapan, LifeAware, Salesforce.com, SpringSource, and ThoughtWorks.

Thanks for making this year's Google I/O a fantastic success! We have much more in store for 2009, so be sure to watch the App Engine blog for updates!
