One of the most frequently asked questions about Accessible Search is: What can I do to make my site rank well on Accessible Search? At the same time, webmasters often ask a similar but broader question: What can I do to rank high on Google Search?

Well I'm pleased to tell you that you can kill two birds with one stone: critical site features such as site navigation can be created to work for all users, including our own Googlebot. Below are a few tips for you to consider.

Ensure that all critical content is reachable

To access content, it needs to be reachable. Users and web crawlers reach content by navigating through hyperlinks, so as a critical first step, ensure that all content on your site is reachable via plain HTML hyperlinks, and avoid hiding critical portions of your site behind technologies such as JavaScript or Flash.

Plain hyperlinks are hyperlinks created via an HTML anchor element <a>. Next, ensure that the target of all hyperlinks i.e. <a> elements are real URLs, rather than using an empty hyperlink while deferring hyperlink behavior to an onclick handler.

In short, avoid hyperlinks of the form:
<a href="#" onclick="javascript:void(...)">Product Catalog</a>

In preference of simpler links, such as:
<a href="http://www.example.com/product-catalog.html">Product Catalog</a>

Ensure that content is readable

To be useful, content needs to be readable by everyone. Ensure that all important content on your site is present within the text of HTML documents. Content needs to be available without needing to evaluate scripts on a page. Content hidden behind Flash animations or text generated within the browser by executable JavaScript remains opaque to the Googlebot, as well as to most blind users.

Ensure that content is available in reading order

Having discovered and arrived at your readable content, a user needs to be able to follow the content you've put together in its logical reading order. If you are using a complex, multi-column layout for most of the content on your site, you might wish to step back and analyze how you are achieving the desired effect. For example, using deeply-nested HTML tables makes it difficult to link together related pieces of text in a logical manner.

The same effect can often be achieved using CSS and logically organized <div> elements in HTML. As an added bonus, you will find that your site renders much faster as a result.

Supplement all visual content--don't be afraid of redundancy!

Making information accessible to all does not mean that you need to 'dumb down' your site to simple text. Making your content maximally redundant is critical in ensuring that your content is maximally useful to everyone. Here are a few simple tips:

• Ensure that content communicated via images is available when those images are missing. This goes further than adding appropriate alt attributes to relevant images. Ensure that the text surrounding the image does an adequate job of setting the context for why the image is being used, as well as detailing the conclusions you expect a person seeing the image to draw. In short, if you want to make sure everyone knows it's a picture of a bridge, wrap that text around the image.


• Add relevant summaries and captions to tables so that the reader can gain a high-level appreciation for the information being conveyed before delving into the details contained within.


• Accompany visual animations such as data displays with a detailed textual summary.

Following these simple tips greatly increases the quality of your landing pages for everyone. As a positive side-effect, you'll most likely discover that your site gets better indexed!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: By Miško Hevery, Google AngularJS team

AngularJS lets you write web applications as if you had a smarter browser.  It lets you extend HTML's syntax to express your application's components clearly and succinctly and lets use standard HTML as your template language.  And it automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding.

Today we are announcing the 1.0 release of AngularJS.  We’d like to thank our early adopters, and we’re excited to share it with you who haven’t yet experienced it.

Our goal with AngularJS is to eliminate the guesswork in creating web app structure and take the pain and the boilerplate out of web client apps.  We think we’re there and we’d love for you to take a look.

AngularJS’s core features are:

• Unobtrusive data binding. AngularJS automatically moves data from the UI to your model and back whenever either of them change.  There are no classes to inherit from, and no wrapper or getter/setter methods to call. Your model can be as simple as a as primitive, native array or as complex as you make it via your custom JavaScript type.
  
  
• HTML as the template. You, your browser, your editors and your other tools already know all about working with HTML.  Why introduce something else?  AngularJS lets you expand HTML’s vocabulary with your own app-specific elements, attributes, and class-types that are fully compatible with the HTML specification.
  
  
• Reusable components -- in HTML! AngularJS gives you the power to extend HTML’s syntax with your own elements, attributes that adds behavior or transforms the DOM.  Want to write <tab>, <calendar>, or <colorpicker> instead of <div><div><div>...?  Want to attach keyboard shortcuts to any element by adding an attribute like key=’ctrl-s’?  You miss the <blink> tag?  All these things and more are possible.
  
  
• Views and Routes. AngularJS lets you switch sub-views in your app with a simple route configuration.  And you get URL deep-linking for free.
  
  
• Tests and Testability. Shipping apps means testing them.  We provide common mocks, we take full advantage of dependency injection, and we encourage MVC structure making it easy to test behavior separate from view. It also comes with an end-to-end scenario runner which eliminates test flakiness by having the runner truly understand application state.

Come and check out our many examples, tutorials, videos and our API docs at angularjs.org.  And we’d love to hear your thoughts and questions on Google+ or on our mailing list.
