salam every one, this is a topic from google web master centrale blog: By John Mueller, Webmaster Trends Analyst, Google Zürich

Last Thursday, many of you just couldn't get enough of us and joined our second live Webmaster Central chat, "JuneTune." It was an action-packed session with live presentations, questions and answers and chatting about cats and other important topics. Over the course of an hour and a half, we made four presentations, received over 600 questions and passed around close to 500 chat messages. It was great to see so many Googlers around the world involved: Adam, Bergy, Evan, Jessica, Maile, Matt (Cutts), Matt (Dougherty), Reid and Wysz in Mountain View; Jonathan and Susan in Kirkland; Alvar, Mariya, Pedro and Uli in Dublin; and me in Zürich. We had users from about as many places as Matt (Harding) has danced in: Alaska, Argentina, Arizona, Australia, Brazil, California, Canada, Chile, Colorado, Costa Rica, Denmark, Egypt, Florida, France, Germany, Greece, Hawaii, India, Indonesia, Ireland, Israel, Italy, Malaysia, Mexico, Minnesota, Missouri, Nebraska, New York, New Zealand, Ohio, Pennsylvania, Peru, Philippines, Poland, Portugal, Saudi Arabia, South Africa, Spain, Switzerland, The Netherlands, Russia, Ukraine, United Kingdom, Vietnam and a bunch from Seattle, Washington - thank you all for joining us!

To help make the most out of this session, we'd like to make the transcripts and presentations available to everyone. We're also working on filling in the blanks and have started to answer many of the unanswered questions online in the Webmaster Help Group. You'll find the full (and just slightly cleaned up) questions and answers there as well.

I presented an overview of factors involved in personalized search at Google:



Maile gave a nice presentation of case sensitivity in web search in general:



The audio part of these presentations is in the audio transcript below. It also includes Jonathan's coverage of reasons why ranking may change, Wysz's presentation of ways to get URLs removed from our index, as well as everything else that happened on the phone! Enjoy :)

salam every one, this is a topic from google web master centrale blog: Webmaster level: Intermediate

While maintaining a website, webmasters may decide to move the whole website or parts of it to a new location. For example, you might move content from a subdirectory to a subdomain, or to a completely new domain. Changing the location of your content can involve a bit of effort, but it’s worth doing it properly.

To help search engines understand your new site structure better and make your site more user-friendly, make sure to follow these guidelines:

• It’s important to redirect all users and bots that visit your old content location to the new content location using 301 redirects. To highlight the relationship between the two locations, make sure that each old URL points to the new URL that hosts similar content. If you’re unable to use 301 redirects, you may want to consider using cross domain canonicals for search engines instead.
• Check that you have both the new and the old location verified in the same Google Webmaster Tools account.
• Make sure to check if the new location is crawlable by Googlebot using the Fetch as Googlebot feature. It’s important to make sure Google can actually access your content in the new location. Also make sure that the old URLs are not blocked by a robots.txt disallow directive, so that the redirect or rel=canonical can be found.
• If you’re moving your content to an entirely new domain, use the Change of address option under Site configuration in Google Webmaster Tools to let us know about the change.

Tell us about moving your content via Google Webmaster Tools

• If you've also changed your site's URL structure, make sure that it's possible to navigate it without running into 404 error pages. Google Webmaster Tools may prove useful in investigating potentially broken links. Just look for Diagnostics > Crawl errors for your new site.
• Check your Sitemap and verify that it’s up to date.
• Once you've set up your 301 redirects, you can keep an eye on users to your 404 error pages to check that users are being redirected to new pages, and not accidentally ending up on broken URLs. When a user comes to a 404 error page on your site, try to identify which URL they were trying to access, why this user was not redirected to the new location of your content, and then make changes to your 301 redirect rules as appropriate.
• Have a look at the Links to your site in Google Webmaster Tools and inform the important sites that link to your content about your new location.
• If your site’s content is specific to a particular region you may want to double check the geotargeting preferences for your new site structure in Google Webmaster Tools.
• As a general rule of thumb, try to avoid running two crawlable sites with completely or largely identical content without a 301 redirection or specifying a rel=”canonical”. 
• Lastly, we recommend not implementing other major changes when you’re moving your content to a new location, like large-scale content, URL structure, or navigational updates. Changing too much at once may confuse users and search engines.
