Some of you won’t be aware of the website validation process, right. So I decided to write an article on the same. Website validation is nothing but a process which ensures that the website works and functions according to the rule and regulations of the internet world. It is very necessary for the World Wide Web to have a regular check on all websites to ensure that they don’t make use of some really illegal tricks and techniques. The process of website validation though not simple is extremely essential for all websites.
If you have a blog or a website then you should know whether your website confirms to the set standards or not and for that you will have access to many tools which will help you perform those tests. There are many online tools available for this purpose. Here in this article, I have displayed 20 such online tools that you make use of to test your website.
Relaxed the HTML Validator
“Relaxed” is basically a swiss knife tool for XML document validation. It is open source and it has been developed in Java. Part of the Relaxed project is a HTML 4.0 / XHTML 1.0 schema written from scratch using Relax NG with embedded Schematron rules. Many additional and even complicated restrictions have been expressed thanks to the combination of those two languages which makes those schemas more powerful that the official DTDs provided by W3C. In addition, Relaxed is able to validate some of the WAI’s WCAG 1.0 restrictions using its own schemas.
Access Color Tool
AccessColor tests the color contrast and color brightness between the foreground and background of all elements in the DOM to make sure that the contrast is high enough for people with visual impairments. Assuring that you provide enough color contrast between foreground and background colors takes time and we hope that this tool will help web developers to build accessible websites by visually flagging the section(s) of a page with problematic color combinations. AccessColor will find the relevant colour combinations within your HTML and CSS documents rather than requiring you to find each value to input yourself in order to test the contrast between each colour combination.

A Checker – Web Accessibility Checker
Dr. Watson’s Site Validation Check
Welcome to version 5 of Dr Watson. The good Doctor started working on Internet web pages sometime in the mid-nineties and has been published in quite a few books on web site development. I’d like to thank all of you for your kind words over the years.
Accessibility with Style
HERA is a tool to check the accessibility of Web pages accoridng to the specification Web Content Accessibility Guidelines. HERA performs a preliminary set of tests on the page and identifies any automatically detectable errors or checkpoints met, and which checkpoints need further manual verification.
W3C Markup Validation Service
This validator checks the markup validity of Web documents in HTML, XHTML, SMIL, MathML, etc. If you wish to validate specific content such as RSS/Atom feeds or CSS stylesheets, MobileOK content, or to find broken links, there are other validators and tools available.
WDG HTML Validator
Enter the URL of an HTML document to validate. To quickly validate multiple URLs, try the batch mode. Alternatively, you can validate files on your computer or you can enter your HTML directly.
W3C Link Checker
This Link Checker looks for issues in links, anchors and referenced objects in a Web page, CSS style sheet, or recursively on a whole Web site. For best results, it is recommended to first ensure that the documents checked use Valid (X)HTML Markup and CSS. The Link Checker is part of the W3C’s validators and Quality Web tools.
STG XML Validation
To validate a small XML document, just paste it into the text field below and hit the validate button. If the document is too large to be conveniently pasted into the text field, enter its filename into the local file field. You may also validate an arbitrary XML document on the Web by typing its URI into the URI field.
Unicorn – W3C’s Unified Validator
The W3C validators rely on community support for hosting and development. Donate and help us build better tools for a better web.
Internet Supervision – URL Check
Monitoring your website’s uptime is imperative to the success of your online endeavors. While it’s important to know if your website is running and your host is providing a good service, it’s even more important to be proactive about getting it back online fast so you don’t lose search engine position, miss out on possible revenue or blow your advertising budget.
Robots Txt Checker
Robots.txt files (often erroneously called robot.txt, in singular) are created by webmasters to mark (disallow) files and directories of a web site that search engine spiders (and other types of robots) should not access. This robots.txt checker is a “validator” that analyzes the syntax of a robots.txt file to see if its format is valid as established by Robot Exclusion Standard (please read the documentation and the tutorial to learn the basics) or if it contains errors.
The validation check is performed against any XML schema or DTD declared inside the XML document. If neither an XML schema nor a DTD is declared, only a syntax check is performed.
To use it, simply enter the address of your feed and click Validate. If the validator finds any problems in your feed, it will give you messages for each type of problem and highlight where the problem first occurs in your feed. If you’re unsure what a message means, click the “help” link next to the message for a fuller explanation.
Total Validator is an (X)HTML validator, an accessibility validator, a spell checker, and a broken links checker all rolled into one tool allowing one-click validation of your web pages. Download this free tool and validate your web pages today:
W3C mobile OK Checker
This checker performs various tests on a Web Page to determine its level of mobile-friendliness. The tests are defined in the mobileOK Basic Tests 1.0 specification. A Web Page is mobileOK when it passes all the tests. Please refer to the About page for more details. If you wish to validate specific content such as markup validitation, or RSS/Atom feeds, or CSS stylesheets, or to find broken links, there are other validators and tools available.
WAVE Web Accessibility Evaluation Tool
WAVE is a free web accessibility evaluation tool provided by WebAIM. It is used to aid humans in the web accessibility evaluation process. Rather than providing a complex technical report, WAVE shows the original web page with embedded icons and indicators that reveal the accessibility of that page.
W3C Feed Validation Service
This is the W3C Feed Validation Service, a free service that checks the syntax of Atom or RSS feeds. The Markup Validation Service is also available if you wish to validate regular Web pages.
