Validate html free or validate html fast

Whatever standard you validate html to - speed counts

Validation of html isn't a new idea. Generally, to validate html, you paste your code into an online validator or give it the url for your site. It then returns a list of errors or tells you everything is fine. The advantages of html validation are pretty clear. As a reminder, they include:

  • Spiders like valid code. Next time Google crawls your site you don't want mistakes in the html stopping it. When you validate html you help visitors to find you.
  • Easier maintenance. It's much easier to take on or return to a project where the code is standards compliant.
  • Compatibility. If your code follows the standards it's more likely to render properly in all the major browsers.

There are many more reasons to validate html, but the above are enough for most people.

How validation usually works

You've probably tried to validate html the traditional way before. The most famous validator is probably the one maintained by the W3C, here. These validators are very useful. They allow you to upload your html or provide a link to it. When you click go they check the page and return a list of errors.

This is simply the way validation works for most people. It's stood the test of time, and the results for a single page are good quality & very useful.



Validating every page at once

With DeepTrawl we've taken a step forward. DeepTrawl validates html just like any other service, but the validation is applied to every page in your site with a single click. No more page by page checks, just instant validation of an entire site at once. A screenshot of how this works is below:

validate html in every page with one click

As shown above, every page in your site which contains a validation error is listed with the errors beneath. DeepTrawl also includes an integrated html editor. You can click 'View in html' to show every error highlighted in your html. The editor also allows you to re-validate with a single click, so you can make a change and instantly check it's had the desired effect.

Advantages

The main advantage when you validate html all at once is speed. If you're working with a single page validator you need to: go to the site, choose the url to validate, click validate & then examine the results. Optimistically, if you're working quickly that might take 20 seconds. Even if it's only 20 seconds, validating all the pages in a 500 page website would take nearly 3 hours.

It seems unlikely anyone could hold their concentration on such a task for that long, so in reality it's probably much more. Besides the other things it does (and there's a lot), a $149 DeepTrawl license will allow you to complete that task in seconds. Then every time you make a change you can re-check all your pages. You keep making the saving over and over.
