Google is constantly trying new ideas to improve our coverage of the web. We already do some pretty smart things like scanning JavaScript and Flash to discover links to new web pages, and today, we would like to talk about another new technology we've started experimenting with recently.

In the past few months we have been exploring some HTML forms to try to discover new web pages and URLs that we otherwise couldn't find and index for users who search on Google. Specifically, when we encounter a <FORM> element on a high-quality site, we might choose to do a small number of queries using the form. For text boxes, our computers automatically choose words from the site that has the form; for select menus, check boxes, and radio buttons on the form, we choose from among the values of the HTML. Having chosen the values for each input, we generate and then try to crawl URLs that correspond to a possible query a user may have made. If we ascertain that the web page resulting from our query is valid, interesting, and includes content not in our index, we may include it in our index much as we would include any other web page.

Needless to say, this experiment follows good Internet citizenry practices. Only a small number of particularly useful sites receive this treatment, and our crawl agent, the ever-friendly Googlebot, always adheres to robots.txt, nofollow, and noindex directives. That means that if a search form is forbidden in robots.txt, we won't crawl any of the URLs that a form would generate.  Similarly, we only retrieve GET forms and avoid forms that require any kind of user information. For example, we omit any forms that have a password input or that use terms commonly associated with personal information such as logins, userids, contacts, etc. We are also mindful of the impact we can have on web sites and limit ourselves to a very small number of fetches for a given site.

The web pages we discover in our enhanced crawl do not come at the expense of regular web pages that are already part of the crawl, so this change doesn't reduce PageRank for your other pages. As such it should only increase the exposure of your site in Google. This change also does not affect the crawling, ranking, or selection of other web pages in any significant way.

This experiment is part of Google's broader effort to increase its coverage of the web. In fact, HTML forms have long been thought to be the gateway to large volumes of data beyond the normal scope of search engines. The terms Deep Web, Hidden Web, or Invisible Web have been used collectively to refer to such content that has so far been invisible to search engine users. By crawling using HTML forms (and abiding by robots.txt), we are able to lead search engine users to documents that would otherwise not be easily found in search engines, and provide webmasters and users alike with a better and more comprehensive search experience.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

salam every one, this is a topic from google web master centrale blog: Webmaster tools from Google are indispensable for people who optimize their site for indexing in Google. Eighteen months ago, Google launched another free tool for webmasters - Google Analytics - which tells you about your visitors and the traffic patterns to your site using a JavaScript code snippet to execute tracking and reporting. This past Tuesday, Google Analytics launched a new version, with an easier-to-use interface that has more intuitive navigation and greater visibility for important metrics. We also introduced some collaboration and customization features such as email reports and custom dashboards.

But we wanted to highlight some of the webmaster-specific metrics within Google Analytics for our regular readers, since it offers a lot of easily-accessible information that will enrich the work you're doing.

For instance, do you know how many visitors to your site are using IE versus Firefox? And even further, how many of those IE or Firefox users are converting on a goal you have set up? Google Analytics can tell you information like this so you can prepare and tailor your website for your audience. Then, when you are designing, you can prioritize your testing to make sure that the site works on the most popular browsers and operating systems first.



Are your visitors using Java-enabled browsers? What version of Flash are the majority of your visitors using? What connection speed do they have? If you find that lots of visitors are using a dial-up service, you're going to want to put in some more effort to streamline the load time of images on your site, for example.

Plus, Google Analytics will make your company's marketing division very happy. It reports on the most effective search keywords, the most popular referring sources and the geographic location of visitors, as well as the performance of banner ads, PPC keyword campaigns, and email newsletters. If you haven't tried Google Analytics, watch the Flash tour of the product or set up a free account now and see statistics on your visitors and the traffic to your site within three hours.

salam every one, this is a topic from google web master centrale blog: Google Gadgets are miniature-sized devices that offer cool and dynamic content -- they can be games, news clips, weather reports, maps, or most anything you can dream up. They've been around for a while, but their reach got a lot broader last week when we made it possible for anyone to add gadgets to their own webpages. Here's an example of a flight status tracker, for instance, that can be placed on any page on the web for free.

Anyone can search for gadgets to add to their own webpage for free in our directory of gadgets for your webpage. To put a gadget on your page, just pick the gadget you like, set your preferences, and copy-and-paste the HTML that is generated for you onto your own page.

Creating gadgets for others isn't hard, either, and it can be a great way to get your content in front of people while they're visiting Google or other sites. Here are a few suggestions for distributing your own content on the Google homepage or other pages across the web:

* Create a Google Gadget for distribution across the web. Gadgets can be most anything, from simple HTML to complex applications. It’s easy to experiment with gadgets – anyone with even a little bit of web design experience can make a simple one (even me!), and more advanced programmers can create really snazzy, complex ones. But remember, it’s also quick and easy for people to delete gadgets or add new ones too their own pages. To help you make sure your gadget will be popular across the web, we provide a few guidelines you can use to create gadgets. The more often folks find your content to be useful, the longer they'll keep your gadget on their pages, and the more often they’ll visit your site.

* If your website has a feed, visitors can put snippets of your content on their own Google homepages quickly and easily, and you don't even need to develop a gadget. However, you will be able to customize their experience much more fully with a gadget than with a feed.

* By putting the “Add to Google” button in a prominent spot on your site, you can increase the reach of your content, because visitors who click to add your gadget or feed to Google can see your content each time they visit the Google homepage. Promoting your own gadget or feed can also increase its popularity, which contributes to a higher ranking in the directory of gadgets for the Google personalized homepage.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com
