Hi Rob!

Yes, this is already in process!

We started by just building an alternative asset-only template for Google AMP, however, there are some tags (like our internal stats code, or base href injected into the page) that are required for BLOX and not permitted on AMP (so the page will not validate). So this requires that we actually update the software to build in knowledge of Google AMP.

We are hoping this will be done in the next month or so, assuming we don't face any other roadblocks. :)

I would definitely do at least 600x600 if you wanted a square logo. Then you'll get the little side-floated image.

Also note that you can apply an og image at the section level (in both Zen and Flex templates). So, you can have a specific image for sports, another for news, another for entertainment, etc. It ends up being a little more specific instead of one single generic photo.

Lastly, some of their sites, as they move to Flex especially, are really emphasizing having images with all articles. This means that BLOX will automatically create a large-sized image of the first content photo to be used as an og.image.

Make sure your og image is the right size. Facebook has increased their desired og image sizes in the past few years, and if it doesn't like your og image (even though that's the image you are specifically telling them to use) they will use something else instead.

They recommend these sizes:

This is on our roadmap!

Yeah that's weird! We'll fix it in the next open release for Flex.
