Why do Squarespace sites create really tiny open-graph SEO images in Slack?

Site URL: https://opinionx.co

As a SaaS startup, we are active in a bunch of Slack-based communities that are relevant to our target customers and also use Slack for internal comms too. 

Whenever I share a link in Slack for a non-Squarespace site, it loads the site preview with a large image. Whenever I share a link to a Squarespace website, the Open-Graph image is really tiny and is placed to the right-hand side rather than beneath. 

Does anyone know why this is? I've also tried it with a bunch of other Squarespace sites (found via this link) and the same happens for all of them. Is there any fix for this or does Squarespace just not have up-to-date Open-Graph API integration?

Try adding Twitter's "Summary Card with Large Image" meta tags to the page, using code injection. For some reason Squarespace doesn't do this by default.

For your homepage, the code would look something like this (replace the parts in caps)

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@YOUR-TWITTER-HANDLE">
<meta name="twitter:title" content="PAGE-TITLE">
<meta name="twitter:description" content="META-DESCRIPTION">
<meta name="twitter:image" content="https://images.squarespace-cdn.com/content/5e22fb8d8524a16d5bd5683c/1629916794384-47XCJWB3ASMFS3SGE17Q/OpinionX+Open-Graph+Image+2021.png?format=1500w&content-type=image%2Fpng">

Not 100% but I'm guessing that will get you the desired result. This is based on Slack's API documentation which seems to prefer to use Twitter image markup for full size images in link previews.

Thanks for the DIY solution, Ed!

I played around with implementing it just now, but given that the problem seems mostly confined to Slack and that I'd have to do a custom implementation for each page (particularly on the blog), I've decided that I'll just leave it as is.

Pity that Squarespace doesn't have this set up for websites properly already, but I've got plenty of other fish to fry. Thanks for the help 🙂

You're welcome. I'm not sure why Squarespace doesn't implement open graph tags the same way most other CMSs do 🤷‍♂️
