Significance of Validating a Website

Validation Tools
Building and hosting your website does not simply serve the purpose. You must make sure that your website conforms to certain specifications laid down by various organizations. These specifications ensure that your website pages are interpreted in a proper manner by search engines as well as users. There are a number of validation application available online, which can be used to validate your site.

Why Validate?
Let us have a look in detail, why it’s important to validate a site when a website still looks perfect in a browser. Websites should conform to the specifications mentioned by the organizations such as W3C for the reasons mentioned below. Validation tools are developed to test if your website conforms to these rules.

Accessibility: These specifications ensure that your site is not only accessible to normal people but also to the physically disabled. In fact, this requirement is not only served as a moral in many countries but also a legal requirement. Therefore, your website should adhere to the W3C Web Accessibility Guidelines or US Section 508 standards.

Search engines: In order to have a site visited more frequently, the website should be properly indexed by search engines. These search engines automatically avoid indexing pages or part of your website if they encounter invalid pages. So it is highly essential for anyone to have their site conformed to these standards for your search engines to properly rank your site.

Visitors: Websites are built and hosted with prime objective of getting users to view it. Therefore in order to have increasingly more users visit a site, one must take care to provide relevant information without broken links.

Maintenance:  These rules can enable a site to be easily maintained and upgraded to fit to the latest trends and developments.

CMS and Tools: The content management systems and authorized tools available today enable anyone with little or no technical knowledge to develop and maintain their own websites. But most of the pages developed through this technique fail to obey the above regulations. Hence it becomes inevitably important to validate a website if you are using these techniques.

What do the tools actually do?
Validation tools are designed to test if a site conforms the aforementioned regulations. They can validate an entire websites code from a missed html tag to spelling mistakes in blogs. A site can be checked by simply entering the site’s page URL. The website can also be validated by uploading r files and directly inputting a chunk of code into a validation tool. The tool can check the HTML, CSS, XHTML, MathML, SMIL etc. of a website. Validator tools do not only validate but also suggest the steps to be taken in order to improve the performance of a website.

Web Accessibility and Skip Navigation

Overview:
An important feature when making a website accessible to disabled users is adding skip navigation.  Adding a skip to content link should be included prior to a website’s navigation tools. A single skip to content link is usually adequate for a website. Adding a skip feature allows users needing assistive screen readers to “skip” between headers and sub headers labeled H2, H3, H4.

Importance of Skip Navigation:
Providing navigation links on a website, on the left hand side or atop the page, will benefit the overall usability and give proper assistance to individuals with mobility impairments. The skip feature, for example, will be highly useful for those that have difficulty operating a mouse or using a screen reader.

Conclusion:
Yet, visually impaired individuals that utilize screen readers may hear all the links at the start of each page, this can be time consuming and cause irritation. It is imperative to add a skip navigation strategy that allows a skip over a block of navigational links for screen readers.

It’s important for every website to have a web accessibility strategy. Implementing web accessibility features improve a sites usability and give access to the widest audience possible. Skip navigation is one of the many features that
