The AMP project has a brand new web validator for AMPlified pages to go along with the Chrome extension launched earlier this month.

You can either provide an AMP URL or you can paste the AMP code directly into the validator to test it.  It won’t find AMPlified for you, so you still need to use the AMP URL to validate.  You can access it at validator.ampproject.org

Here is an example of a page that passes validation.

And one that doesn’t:

The web validator is also open source.

They also recently launched the Chrome AMP validator, and it is a great tool to use while checking out webpages.  Not only will it check for AMP validation and show an icon whether it validates or not, the icon will also change to show when you are looking at a regular version but there is an AMP version available, which is a great tool to have just for general surfing.

Google has been promoting AMP aggressively this year and have been expanding it since it originally launched – as of last month there were 125 million AMPlified pages indexed.  It recently expanded into recipes and it is expected to continue to expand across the search results.
