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

One of the great things about working at Google is that we get to take advantage of an enormous amount of computing power to do some really cool things. One idea we tried out was to let webmasters know about their potentially hackable websites. The initial effort was successful enough that we thought we would take it one step further by expanding our efforts to cover other types of web applications—for example, more content management systems (CMSs), forum/bulletin-board applications, stat-trackers, and so on.

This time, however, our goal is not just to isolate vulnerable or hackable software packages, but to also notify webmasters about newer versions of the software packages or plugins they're running on their website. For example, there might be a Drupal module or Joomla extension update available but some folks might not have upgraded. There are a few reasons a webmaster might not upgrade to the newer version and one of the reasons could be that they just don't know a new version exists. This is where we think we can help. We hope to let webmasters know about new versions of their software by sending them a message via Webmaster Tools. This way they can make an informed decision about whether or not they would like to upgrade.

One of the ways we identify sites to notify is by parsing source code of web pages that we crawl. For example, WordPress and other CMS applications include a generator meta tag that specifies the version number. This has proven to be tremendously helpful in our efforts to notify webmasters. So if you're a software developer, and would like us to help you notify your users about newer versions of your software, a great way to start would be to include a generator meta tag that tells the version number of your software. If you're a plugin or a widget developer, including a version number in the source you provide to your users is a great way to help too.

We've seen divided opinions over time about whether it's a good security practice to include a version number in source code, because it lets hackers or worm writers know that the website might be vulnerable to a particular type of exploit. But as Matt Mullenweg pointed out, "Where [a worm writer's] 1.0 might have checked for version numbers, 2.0 just tests [a website's] capabilities...". Meanwhile, the advantage of a version number is that it can help alert site owners when they need to update their site. In the end, we tend to think that including a version number can do more good than harm.

We plan to begin sending out the first of these messages soon and hope that webmasters find them useful! If you have any questions or feedback, feel free to comment here.

salam every one, this is a topic from google web master centrale blog: Good news for webmasters of English-language news sites: If your site is currently included in Google News, you can now create News Sitemaps that tell us exactly which articles to crawl for inclusion in Google News. In addition, you can access crawl errors, which tell you if there were any problems crawling the articles in your News Sitemaps, or, for that matter, any articles on your site that Google News reaches through its normal crawl.

Freshness is important for news, so we recrawl all News Sitemaps frequently. The News Sitemaps XML definition lets you specify a publication date and time for each article to help us process fresh articles in timely fashion. You can also specify keywords for each article to inform the placement of the articles into sections on Google News.

If your English-language news site is currently included in Google News, the news features are automatically enabled in webmaster tools; just add the site to your account. Here's how the new summary page will look:

The presence of the News crawl link on the left indicates that the news features are enabled. A few things to note:

• You will only have the news features enabled if your site is currently included in Google News. If it's not, you can request inclusion.

• In most cases, you should add the site for the hostname under which you publish your articles. For example, if you publish your articles at URLs such as http://www.example.com/business/article123.html, you should add the site http://www.example.com/. Exception: If your site is within a hosting site, you should add the site for your homepage, e.g., http://members.tripod.com/mynewssite/. If you publish articles under multiple hostnames, you should add a site for each of them.

• You must verify your site to enable the news features.

We'll be working to make the news features available to publishers in more languages as soon as possible.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com
