what is the DOM?
Posted on: August 6, 2009
DOM stands for Document Object Model is a W3C (World Wide Web Consortium) standard.
The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document.
DOM has three different levels:
1. Core DOM – standard model for any structured document.
2. HTML DOM – standard model for HTML documents.
3. XML DOM – standard model for XML documents.
DOM also defines the objects and properties of all document elements, and the methods (interface) to access them.
The HTML DOM is a standard for how to get, change, add, or delete HTML elements.
The XML DOM defines the objects and properties of all XML elements, and the methods (interface) to access them.
I don’t think so but, its not yet proved that validation gives you better search engine ranking. But for sure that errors can create you lot of problems. Converting your website pages to XHTML will help you reach more customers, as your site will work better in more browsers and non-traditional devices. The W3C validation is just a standard for specified machine language, checking web documents, spelling, grammar, syntax, and proofreading.
XHTML is the newest standard markup language designed for web documents a combination of HTML and XML. Converting your HTML page to XHTML will take time as you need to check for the syntax and all.
The search engines might search your HTML or XHTML code of your website in search of relevant content. If they find invalid HTML or XHTML code – meaning code that is not following the official rules, you might be removed from indexes. If there is an error on your web page code, spiders will stop searching your whole website, and this could very well be the end of your optimization efforts. All errors doesn’t cause or lead to search engine rankings.
Spend some time and validate your code, fortunately there are some free services that allow you to check your documents for compliance with web standards. The W3C’s free online Validation Service (validator.w3.org ) is used by many professionals to ensure their sites comply with web standards.
Making your site 100% validated doesn’t mean or make our site first rank. But it makes you reach larger clients or audience and improve your long-term search engine optimization strategy for your business.
