salam every one, this is a topic from google web master centrale blog: Written by Raj Krishnan, Snippets Team

The quality of your snippet — the short text preview we display for each web result — can have a direct impact on the chances of your site being clicked (i.e. the amount of traffic Google sends your way). We use a number of strategies for selecting snippets, and you can control one of them by writing an informative meta description for each URL.


Why does Google care about meta descriptions?
We want snippets to accurately represent the web result. We frequently prefer to display meta descriptions of pages (when available) because it gives users a clear idea of the URL's content. This directs them to good results faster and reduces the click-and-backtrack behavior that frustrates visitors and inflates web traffic metrics. Keep in mind that meta descriptions comprised of long strings of keywords don't achieve this goal and are less likely to be displayed in place of a regular, non-meta description, snippet. And it's worth noting that while accurate meta descriptions can improve clickthrough, they won't affect your ranking within search results.

What are some good meta description strategies?
Differentiate the descriptions for different pages
Using identical or similar descriptions on every page of a site isn't very helpful when individual pages appear in the web results. In these cases we're less likely to display the boilerplate text. Create descriptions that accurately describe each specific page. Use site-level descriptions on the main home page or other aggregation pages, and consider using page-level descriptions everywhere else. You should obviously prioritize parts of your site if you don't have time to create a description for every single page; at the very least, create a description for the critical URLs like your homepage and popular pages.

Include clearly tagged facts in the description
The meta description doesn't just have to be in sentence format; it's also a great place to include structured data about the page. For example, news or blog postings can list the author, date of publication, or byline information. This can give potential visitors very relevant information that might not be displayed in the snippet otherwise. Similarly, product pages might have the key bits of information -- price, age, manufacturer -- scattered throughout a page, making it unlikely that a snippet will capture all of this information. Meta descriptions can bring all this data together. For example, consider the following meta description for the 7th Harry Potter Book, taken from a major product aggregator.

Not as desirable:

There are a number of reasons this meta description wouldn't work well as a snippet on our search results page:

• The title of the book is complete duplication of information already in the page title.
• Information within the description itself is duplicated (J. K. Rowling, Mary GrandPré are each listed twice).
• None of the information in the description is clearly identified; who is Mary GrandPré?
• The missing spacing and overuse of colons makes the description hard to read.

All of this means that the average person viewing a Google results page -- who might spend under a second scanning any given snippet -- is likely to skip this result. As an alternative, consider the meta description below.

Much nicer:

What's changed? No duplication, more information, and everything is clearly tagged and separated. No real additional work is required to generate something of this quality: the price and length are the only new data, and they are already displayed on the site.

Programmatically generate descriptions
For some sites, like news media sources, generating an accurate and unique description for each page is easy: since each article is hand-written, it takes minimal effort to also add a one-sentence description. For larger database-driven sites, like product aggregators, hand-written descriptions are more difficult. In the latter case, though, programmatic generation of the descriptions can be appropriate and is encouraged -- just make sure that your descriptions are not "spammy." Good descriptions are human-readable and diverse, as we talked about in the first point above. The page-specific data we mentioned in the second point is a good candidate for programmatic generation.

Use quality descriptions
Finally, make sure your descriptions are... descriptive. It's easy to become lax on the quality of the meta descriptions, since they're not directly visible in the UI for your site's visitors. But meta descriptions might be displayed in Google search results -- if the description is high enough quality. A little extra work on your meta descriptions can go a long way towards showing a relevant snippet in search results. That's likely to improve the quality and quantity of your user traffic.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

Good news for Google Gadget developers. We've just launched Google Gadget Ventures, a new pilot program for distributing grants and seed investments to gadget developers and gadget-related businesses. We're excited about the opportunity this will give developers to build even richer, more useful gadgets and get recognized for doing it.

The program will provide two kinds of funding. First, we'll invite promising gadget developers (individuals or businesses) to apply for $5,000 grants to fund further development. These are not loans or equity investments; they're simply grants for gadgets that already have a thriving user base and we think have potential for even more improvement. To be considered for a grant, your gadget needs to have more than 250,000 pageviews per week, and you need to provide a one-page proposal on how you'd like to improve your gadget. This is a no-strings-attached grant; we won't ask for repayment of any kind. We simply ask that you work on your project in good faith.

Secondly, the program will make $100,000 seed investments in companies that either start as a Google Gadget or have a large Google Gadget component. In order to be eligible for a seed investment, you must have received a $5,000 grant, and you must propose a plan for making your gadget financially sustainable.

If you're interested in creating your own Google Gadget, we have several tools that can help. The Google Mashup Editor has an option for instantly deploying your web app as a gadget. For Java programmers, Google Web Toolkit provides another good way to write a gadget or a full-featured AJAX app with a gadget component. The Google Data APIs and AJAX Feed API can help power your gadget with rich data sources. You can even add offline functionality using Google Gears.

We hope you find these tools useful for creating gadgets, and we're eager to hear what you think in the Google Gadgets discussion group.2013, By: Seo Master

Cross-posted with the Google Apps Developer Blog

Today at Google I/O, we announced many enhancements to Google Apps Script to help you build richer applications and share your apps with users. Apps Script began  as a tool for helping users get more done with their Google spreadsheets. Over time, Apps Script has grown to handle much more. It's a platform to extend Google spreadsheets and Sites, and a convenient way to create web applications.

We launched script.google.com  as a destination for Apps Script developers. You can now create scripts from script.google.com  or from Google Drive. Plus, your projects are now stored in Google Drive, and you can share them just like a Google document or spreadsheet.

HtmlService  can help you create beautiful interfaces using Apps Script. HtmlService allows you to create web apps using HTML, client-side JavaScript, and CSS. You can also use jQuery to build web apps. HtmlService uses Google Caja  to ensure that the HTML content served by your web apps is safer for you and your users.

We also launched a better way to store your application's data, ScriptDb . Every script now has an embedded JSON database. You no longer have to rely on a spreadsheet to store the data. Using ScriptDb, you can store a larger volume of data and search easily. We designed ScriptDb to be easy to use. It doesn't need connection strings or special passwords, and you can directly store and search your JavaScript objects without the need to convert them to a different format. You can learn more about ScriptDb on the Google Apps Script Developers page.

There are also now more options for deploying your web app. Your apps can now, with authorization, run as the user behind the keyboard, not just the script owner. This brings a new level of versatility to web apps built with Apps Script.

Finally, we wanted to make it easy to distribute your apps. You can now publish your apps in the Chrome Web Store . Register and package your app directly from the Publish menu in Google Apps Script. Then customize your listing from the Chrome Web Store and publish your app to the world.

We added a lot of new functionality to Apps Script, so in addition to our developer reference documentation , we've also created a new user guide . If you need further help you can reach out to us on Stack Overflow . You can also make feature requests and report issues on the Apps Script page on Google Code.

Building with Google Apps Script has become a lot easier and more powerful. We can't wait to see what you build. Happy scripting!
