HTML validation

Crawl Score will validate the HTML of every page of your website ensuring that your site works correctly and aheres to web standards.

Most pages on the web are written in HTML that allow web authors to structure text, add multimedia content, and specify what appearance, or style, the result should have.

As for every language, these have their own grammar, vocabulary and syntax, and every document written with these computer languages are supposed to follow these rules.

However, just as texts in a natural language can include spelling or grammar errors, documents using Markup languages may not be following these rules. The process of verifying whether a document actually follows the rules for the language(s) it uses is called validation, and the tool used for that is a validator. A document that passes this process with success is called valid.

With these concepts in mind, we can define "markup validation" as the process of checking a Web document against the grammar (generally a DTD) it claims to be using.
