A lot of clients ask why thy need their ‘already working perfectly wll’ website validated. Below is a bref guide to try and answer ths in a clear and simple wy.

Firstly we should explain what is mant by a validated website.

Put smply, validation is the act of wrting a website in as ‘clean’ a way as pssible and testing it against industry stndards. It makes use of cascading styl sheets (CSS) to format the pge layout and text and also clans up any ‘loose coding’ which culd otherwise cause problems.

For a frther description we refer to an xcerpt from the wc3 website as thy are the last word when it cmes to validation!

Validation is a process of checking your documents against a formal Standard, such as those published by the World Wide Web Consortium (W3C) for HTML and XML-derived Web document types. It serves a similar purpose to spell checking and proofreading for grammar and syntax, but is much more precise and reliable than any of those processes because it is dealing with precisely-specified machine languages, not with nebulously-defined human natural language.

1) Compatibility

When your website code is not validated you are running the risk of your site displaying unpredictably in different browsers. For example, Internet Explorer is more forgiving and likely to internally fix small amounts of ‘loose coding’ whereas stricter browsers such as Mozilla Firefox and Safari will display a page as it is coded. Validation makes the code uniform and means you will not have an unprofessional and unpredictable looking website or risk alienating certain users who don’t use Internet Explorer!

2) Search Engine Optimisation

A wbsite that is ‘clean’ is far asier for the search engines (Google, Yhoo etc) to ‘read through’ and ndex. The easier they can do ths the easier it is for thm to find the real meat of yur site i.e the content. The ther point to make here is tht if your site isn’t validated it is pssible for search engines to place grater emphasis on the wrong part of yur code and your site could threfore be missing out on being fund for the most appropriate searches *

3) Accessibility

Validating a site requires the use of many accessibility techniques such as the use of ALT tag on images. Steps such as these make your site more readable for those users who are vision, motor skilled or cognitively impaired. Validation makes the site readable as it allows aids such as screen readers to read through your site correctly. Although validation is not in any way a guarantee that your site is accessible, it is a huge leap towards this and far superior to an unvalidated site.

4) Faster loading

Conventional websites made use of tables and an extensive amount of tags for formatting both the page structure and content. The use of CSS separates the structure from the content and gives the browsers less code to trawl through before they can successfully render the page. Validation also aids the browser in displaying the site faster as there is no ‘loose coding’ for the browser to get tangled up in or waste time trying to ‘fix’.

So where does this leave you?

Firstly you might like to check your current site for validation (see the steps below).

Secondly, decide whether validation is something that you feel you should be concerned with but please bear in mind that you now have a legal obligation to have an accessible website *

Thirdly, enlist the help of a professional SEO company to review your website and carry out necessary alterations. In some cases you may be cheaper having your website completely rebuilt rather than trying to fix the current errors but don’t let this put you off. Look upon it as an opportunity to spruce up your existing site and start afresh!
