Deva HTML/xHTML Validator Component

As a web tool, Deva HTML/xHTML Validator is integrated in the Deva xFTP main program. It is one of the important and very useful components of Deva xFTP for web developers and masters.

What is valid HTML code?

Most web pages are written in hypertext markup language or extensible hypertext markup language.

As for every language, HTML/XHTML has its own grammar, vocabulary and syntax, every document written in this language is supposed to follow these rules.

Like any language, hypertext markup language or extensible hypertext markup language is constantly changing. As the language has become a relatively complex language, it's very easy to make mistakes.

The code that is not following the official rules is called invalid HTML code.

Why is valid HTML code important?

Search engines have to parse the HTML code of your web site to find the relevant content. If your HTML code contains errors, search engines might not be able to find everything on the page.

Search engine crawler programs obey the HTML standard.

Search engine crawler programs can only index your web site if it is compliant with the HTML standard. If there's a mistake in your web page code, they might stop crawling your web site and they might lose what they've collected so far because of the error.

Although most major search engines can deal with minor errors in HTML code, a single missing bracket in your HTML code can be the reason if your web page cannot be found in search engines.

If you don't close some tags properly, or if some important tags are missing, search engines might ignore the complete content of that page.
