Google have added a mobile usability section to their webmaster tools console and Search Engine Watch have written a piece that coincides nicely with this with some top tips on optimising your site for mobile devices, a link to which you'll find at the bottom of the page.

The last tip they give is in relation to Google's Accelerated Mobile Pages project or AMP for short.

It's more than likely you've experienced an AMP page on your mobile even if you weren't aware of it. News stories that appear in Facebook or as image rich snippets from Google searches are often AMP powered. Essentially it takes away all the clutter and load of the 'stuff' surrounding the content on a normal page and just delivers up the article. It's a really quick and I think exciting way of presenting data to a mobile user. But it's last on the SEW list, and if you read the article, there's another article about the slow adoption of the technology. Why is this?

From a personal perspective, I've only implemented AMP on one site so far. It was a WordPress site, brand new fresh out of the box and what I found was the plugin from Automattic only supports posts and not pages. The majority of our sites only use pages, even those with news and events sections have a custom post type which again isn't supported so you have to use the default post type to get it to work. I'm guessing Automattic figured you'd just want blog articles to be AMP friendly and therefore limited it to posts only.

Our blogs are usually through HubSpot, and at the moment they're not supporting AMP but hopefully that will change soon. I think in the case of both development teams, whilst it's fine to present a blog article in fixed AMP format, you're going to have to give editors the choice as to whether individual pages or pages of a certain type are AMP pages or simply responsive mobile pages, which might be causing the delay in expansion and inclusion of the technology. At the moment with WordPress you have append 'amp' to the end of the standard address to get the amp version.

Personally I think AMP gives a great user experience on mobile and I look forward to hopefully seeing it expand into all areas of prominent CMSs like WordPress and HubSpot COS so we can provide better journeys for mobile users across all our sites.
