To build a great web search engine, you need to:

1. Crawl a large chunk of the web.
2. Index the resulting pages and compute how reputable those pages are.
3. Rank and return the most relevant pages for users' queries as quickly as possible.

For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google's web search. It's the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions. The new infrastructure sits "under the hood" of Google's search engine, which means that most users won't notice a difference in search results. But web developers and power searchers might notice a few differences, so we're opening up a web developer preview to collect feedback.

Some parts of this system aren't completely finished yet, so we'd welcome feedback on any issues you see. We invite you to visit the web developer preview of Google's new infrastructure at http://www2.sandbox.google.com/ and try searches there.

Right now, we only want feedback on the differences between Google's current search results and our new system. We're also interested in higher-level feedback ("These types of sites seem to rank better or worse in the new system") in addition to "This specific site should or shouldn't rank for this query." Engineers will be reading the feedback, but we won't have the cycles to send replies.

Here's how to give us feedback: Do a search at http://www2.sandbox.google.com/ and look on the search results page for a link at the bottom of the page that says "Dissatisfied? Help us improve." Click on that link, type your feedback in the text box and then include the word caffeine somewhere in the text box. Thanks in advance for your feedback!

Update on August 11, 2009: [ If you have language or country specific feedback on our new system's search results, we're happy to hear from you. It's a little more difficult to obtain these results from the sandbox URL, though, because you'll need manually alter the query parameters.

You can change these two values appropriately:
hl = language
gl = country code

Examples:
German language in Germany: &hl=de&gl=de
http://www2.sandbox.google.com/search?hl=de&gl=de&q=alle+meine+entchen

Spanish language in Mexico: &hl=es&gl=mx
http://www2.sandbox.google.com/search?hl=es&gl=mx&q=de+colores

And please don't forget to add the word "caffeine" in the feedback text box. :) ]

Just in time for the holidays, the Webmaster Tools team has updated the "Search queries" and "Links to your site" features.

Search queries with top pages:
Throughout the past year we’ve made some significant changes to the search queries feature in Webmaster Tools. We've received lots of feedback about this tremendously popular feature. One frequent request we heard was that people wanted to be able to see search queries data for their site’s individual pages. Well, we totally agreed that this would be useful and promptly set out to add this functionality to search queries. The fruits of our effort have finally ripened enough on the vine and are ready for you to enjoy. Now when you visit the search queries feature in Webmaster Tools you'll see a new tab titled "Top Pages." The "Top Pages" tab lists impression, click, and position data for the top pages on your site based on their performance in Google's search results.


If you click on one of the individual pages listed you’ll see a list of the queries driving traffic to that page, along with impressions and number of clicks for each query.


Just like in the "Top queries" view, you can click on a specific query to see more detailed data and evaluate how the query is performing across the whole site.


To make filtering in search queries even easier, we've added pie charts to show visually the proportions of search type, location and traffic. Also in the "Top queries" view, you can now specify “containing” or “not containing” when filtering queries.


Links to your site with intermediate links:
Links to your site now shows when a particular URL redirects. If there's a link to your site that links to URL1 which then redirects to URL2, we are now showing the link from URL1 to URL2 as an intermediate link. We also added a "Download all links" option to all the tables in the Links to your site feature.


Now that you know about these updates, please take a few minutes to check them out for your site. We hope it will provide you with a little bit of extra joy this holiday season. Let us know what you think by submitting a comment here or posting in our Webmaster Help Forum. Happy Holidays from the Webmaster Tools team!

Seo Master present to you: If you attended Google I/O 2009 a few weeks ago, you may have noticed a kiosk station on the 2nd and 3rd floors of Moscone West labelled 'Interactive Conference Map, powered by Google Maps'. The kiosk simply pointed to a JavaScript Maps API-based interactive map of the venue I created in my 20% time.

Now that all the I/O session videos and presentations are live, we took the opportunity to mash up the videos with our interactive conference map to provide developers with an alternate way to navigate through 80+ keynote and session videos, and bring the action at I/O to life virtually. For example, here are videos of sessions that took place in Room 1 (click the tabs for Wednesday and Thursday sessions). And here's where the keynote sessions took place. Check out where we filmed interviews with I/O sandbox developers on their apps, technical challenges and business best practices.


Now, hopefully you enjoyed using the map and are now thinking, "Cool, I want to do something like this for my next event!" (or your college campus, or such). If you are, then good news everyone, I've open sourced the interactive conference map and all relevant resources. Inside the project, you'll also find a how to article outlining the steps I went through to create the map.

If you attended I/O, then I hope you enjoyed it and had time to stop by the conference map kiosk! If not, no worries, just make sure to check out the open source project and see if you can use the code and/or techniques in your next mapping project!

Seo Master present to you: On April 7th, Google launched a new version of Gmail for mobile for iPhone and Android-powered devices. We shared the behind-the-scenes story through this blog and decided to share more of our learnings in a brief series of follow-up blog posts. This week, I'll talk about a few small things you can do to improve performance of your HTML5-based applications. Our focus here will be on performance bottlenecks related to the database and AppCache.

Optimizing Database Performance

There are hundreds of books written about optimizing SQL and database performance, so I won't bother to get into these details, but instead focus on things which are of particular interest for mobile HTML5 apps.

Problem: Creating and deleting tables is slow! It can take upwards of 200 ms to create or delete a table. This means a simple database schema with 10 tables can easily take 2-4 seconds (or more!) just to delete and recreate the tables. Since this often needs to be done at startup time, this really hurts your launch time.

Solution: Smart versioning and backwards compatible schema changes (whenever possible). A simple way of doing this is to have a VERSION table with a single row that includes the version number (e.g., 1.0). For backwards-compatible version changes, just update the number after the decimal (e.g., 1.1) and apply any updates to the schema. For changes that aren't backwards compatible, update the number before the decimal (e.g., 2.0) at which point you can drop all the tables and recreate them all. With a reasonable schema design to begin with, it should be very rare that a schema change is not backwards compatible and even if this happens every month or so, users should get to use your application 20, 30 even 100 times before they hit this startup delay again. If your schema changes very infrequently, a simple 1, 2, 3 versioning scheme will probably work fine; just make sure to only recreate the database when the version changes!

Problem: Queries are slow! Queries are faster than creates and updates, but they can still take 100ms-150ms to execute. It's not uncommon for traditional applications to execute dozens or even hundreds of queries at startup – on mobile this is not an option.

Solution: Defer and/or combine queries. Any queries that can be deferred from startup (or at any other significant point in the application) should be deferred until the data is absolutely needed. Adding 2-3 more queries on a user-driven operation can turn an action from appearing instantaneous to feeling unresponsive. Any queries that are performed at startup should be optimized to require as few hits to the database as possible. For example, if you're storing data about books and magazines, you could use the following two queries to get all the authors along with the number of books and magazine articles they've writen:

SELECT Author, COUNT(*) as NumArticles
FROM Magazines
GROUP BY Author
ORDER BY NumArticles;

SELECT Author, COUNT(*) as NumBooks
FROM Books
GROUP BY Author
ORDER BY NumBooks;

This will work fine, but the additional query will generally cost you about 100-200 ms over a different (albeit less pretty) query like:

SELECT Author, NumPublications, PubType
FROM (
  SELECT Author, COUNT(*) as NumPublications, 'Magazine' as PubType, 0 as SortIndex
  FROM Magazines
  GROUP BY Author
  UNION
  SELECT Author, COUNT(*) as NumPublications, 'Book' as PubType, 1 as SortIndex
  FROM Books
  GROUP BY Author
)
ORDER BY SortIndex, NumPublications;

This will return all the entries we want, with the magazine entries first in increasing order of number of articles, followed by the book entries, in increasing order of the number of books. This is a toy example and there are clearly other ways of improving this, such as merging the Magazines and Books tables, but this type of scenario shows up all the time. There's always a trade-off between simplicity and speed when dealing with databases, but in the case of HTML5 on mobile, this trade-off is even more important.

Problem: Multiple updates is slow!

Solution: Use Triggers whenever possible. When the result of a database update requires updating other rows in the database, try to do it via SQL triggers. For example, let's say you have a table called Books listing all the books you own and another called Authors storing the names of all the authors of books you own. If you give a book away, you'll want to remove it from the Books table. However, if this was the only book you owned by that author, you would also want to remove the author from the Authors table. This can be done with two UPDATE statements, but a "better" way is to write a trigger that automatically deletes the author from the Authors table when the last book by this author is removed. This will execute faster and because triggers happen asynchronously in the background, it will have less of an impact on the UI than executing two statements. Here's an example of a simple trigger for this case:

CREATE TRIGGER IF NOT EXISTS RemoveAuthor
AFTER DELETE ON Books
BEGIN
  DELETE FROM Authors
  WHERE Author NOT IN
    (SELECT Author
     FROM Books);
END;

We'll get into more detail on triggers and how to use them in another performance post to come.

Optimizing AppCache Performance

Problem: Logging in is slow!

Solution: Avoid redirects to the login page. App-Cache is great because it can launch the application without needing to hit the network, which makes it much faster and allows you to launch offline. One problem you might encounter though, is that the application will launch and then you'll need to hit the network to get some data for the current user. At this point you'll have to check that the user is authenticated and it might turn out that they're not (e.g., their cookies might have expired or have been deleted). One option is to redirect the user to a login page somewhere, allow him to authenticate and then redirect him back to the application. Regardless of whether or not the login page is listed in the manifest, when it redirects back to your application, the entire application will reload. A nicer approach is for the application itself to display an authentication interface which sends the credentials and does the authentication seamlessly in the background. This will avoid any additional reloads of the application and makes everything feel faster and better integrated.

Problem: AppCache reloading causes my app to be slow!

Solution: List as few URLs in the manifest as possible. In a series of posts on code.google.com, we talked about the HTML5 AppCache manifest file. An important aspect of the manifest file is that when the version gets updated, all the URLs listed in the file are fetched again. This happens in the background while the user is using the application, but opening all these network connections and transferring all that data can cause the application to slow down considerably during this process. Try to setup your application so that all the resources can be fetched from as few URLs as possible to speed up the manifest download and minimize this effect. Of course you could also just never update your manifest version, but what's the point of having rapid development if you never make any changes?


That's a brief intro to some performance considerations when developing HTML5 applications. These are all issues that we ran into ourselves and have either fixed or are in the process of fixing in our application. I hope this helps you to avoid some of the issues we ran into and makes your application blazing fast!

We plan to write several more performance related posts in the future, but for now stay tuned for next post where we'll discuss the cache pattern for building offline capable web applications.

salam every one, this is a topic from google web master centrale blog: (This post was translated from our German webmaster blog, originally written by Stefanie.)

We are aware that a number of German webmasters have received fake penalty notification emails that allegedly came from Google Search Quality. These spam emails have created some confusion about their authenticity, since we send very similar email notifications, which you can read more about here. Therefore, we clearly want to state that these emails are not related to any of Google's efforts concerning webmaster notification.

Updated: Because these emails are easy to mistake for authentic ones from Google, we've temporarily discontinued sending them as we work on ways to provide more secure communication mechanisms. We hope this will reduce confusion.

In the original post, we had listed the ways to tell if the email you received was not from Google. However, as we've temporarily stopped sending emails about guidelines violations, you can safely assume that any email you receive isn't from us. Note that the emails we sent did not include attachments. In addition, some of the emails mentioned 301 redirects as being the violation in question. Rest assured that 301 redirects are not a violation of our Webmaster Guidelines. Note that we do provide information about some violations in webmaster tools. If your site previously violated the guidelines and you've made changes to fix it, you can let us know by filing a reinclusion request.

This post has been updated to indicate that we've temporarily stopped sending emails to webmasters about guidelines violations to reduce confusion.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

Seo Master present to you: At Google, we're passionate about making the web faster. To help web page owners optimize their pages for speed, we open-sourced the Page Speed web performance tool a year ago. Today, we're excited to launch a new Page Speed feature: Page Speed for ads, such as display and rich media ads, and trackers, also known as analytics.

Page Speed now enables developers to run a performance analysis of the ads, the trackers, or the remaining content of the page. Web developers can use Page Speed to determine how ads and trackers impact the performance of their web pages, and ad and tracker providers can use this feature to tune their services for speed.

For instance, when analyzing an example web page, Page Speed displays several suggestions that we can apply to make the page faster:


But which of these suggestions applies to the content on the page that we authored? Which apply to the ads and trackers? Using the "Analyze"menu, we can determine that, in this example, the ads are contributing to slowing down the page:


When we switch to analyze the content of the page, the score for the page improves to 93. We can in this case enable compression for the resource that is served uncompressed currently.


We hope that you try these and other new features and rules of Page Speed and find them useful to further optimize the speed of your web pages.

Please share your experience using this new feature in our discussion forum.

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

If your page is on the web, speed matters. For developers and webmasters, making your page faster shouldn’t be a hassle, which is why we introduced mod_pagespeed in 2010. Since then the development team has been working to improve the functionality, quality and performance of this open-source Apache module that automatically optimizes web pages and their resources. Now, after almost two years and eighteen releases, we are announcing that we are taking off the Beta label.

We’re committed to working with the open-source community to continue evolving mod_pagespeed, including more, better and smarter optimizations and support for other web servers. Over 120,000 sites are already using mod_pagespeed to improve the performance of their web pages using the latest techniques and trends in optimization. The product is used worldwide by individual sites, and is also offered by hosting providers, such as DreamHost, Go Daddy and content delivery networks like EdgeCast. With the move out of beta we hope that even more sites will soon benefit from the web performance improvements offered through mod_pagespeed.

mod_pagespeed is a key part of our goal to help make the web faster for everyone. Users prefer faster sites and we have seen that faster pages lead to higher user engagement, conversions, and retention. In fact, page speed is one of the signals in search ranking and ad quality scores. Besides evangelizing for speed, we offer tools and technologies to help measure, quantify, and improve performance, such as Site Speed Reports in Google Analytics, PageSpeed Insights, and PageSpeed Optimization products. In fact, both mod_pagespeed and PageSpeed Service are based on our open-source PageSpeed Optimization Libraries project, and are important ways in which we help websites take advantage of the latest performance best practices.



To learn more about mod_pagespeed and how to incorporate it in your site, watch our recent Google Developers Live session or visit the mod_pagespeed product page.

Seo Master present to you: We recently published deprecation policies for a number of APIs that graduated from Google Code Labs. They state how long we'll support each version from when it's deprecated or a newer version is introduced. It will be 3 years for most, but the time period varies a bit from product to product.

• AdWords API terms
• AdSense API terms
• AJAX Feed API terms
• AJAX Language API terms
• AJAX Libraries API terms
• AJAX Search API terms
• Apps APIs terms
• Calendar Data API terms
• Chart API terms
• Health API terms
• Geo APIs terms (Earth API, Mapplets, Maps API, Maps API for Flash, and Static Maps API)
• Secure Data Connector terms

We still need to update the terms for a couple remaining graduates, but should have them all done within the next couple weeks.

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

Webmaster Level: All

The homepages of multinational and multilingual websites are sometimes configured to point visitors to localized pages, either via redirects or by changing the content to reflect the user’s language. Today we’ll introduce a new rel-alternate-hreflang annotation that the webmaster can use to specify such homepages that is supported by both Google and Yandex.

To see this in action, let’s look at an example. The website example.com has content that targets users around the world as follows:

• http://example.com/en-gb: For English-speaking users in the UK
• http://example.com/en-us: For English-speaking users in the USA
• http://example.com/en-au: For English-speaking users in Australia
• http://example.com/: The homepage shows users a country selector and is the default page for users worldwide

In this case, the webmaster can annotate this cluster of pages using rel-alternate-hreflang using Sitemaps or using HTML link tags like this:

<link rel="alternate" href="http://example.com/en-gb" hreflang="en-gb" />
<link rel="alternate" href="http://example.com/en-us" hreflang="en-us" />
<link rel="alternate" href="http://example.com/en-au" hreflang="en-au" />
<link rel="alternate" href="http://example.com/" hreflang="x-default" />

The new x-default hreflang attribute value signals to our algorithms that this page doesn’t target any specific language or locale and is the default page when no other page is better suited. For example, it would be the page our algorithms try to show French-speaking searchers worldwide or English-speaking searchers on google.ca.

The same annotation applies for homepages that dynamically alter their contents based on a user’s perceived geolocation or the Accept-Language headers. The x-default hreflang value signals to our algorithms that such a page doesn’t target a specific language or locale.

As always, if you have any questions or feedback, please tell us in the Internationalization Webmaster Help Forum.
