Today I made a small change to my blog, I added some more HTML metadata for the Open Graph protocol.
Basically, when you share an url in most social networks or instant messaging, when some Open Graph headers are present the software will display you the website name, the page title, a logo and some other information. Without that, only the link will be displayed.
You need to add a few tags to your HTML pages in the "head" tag.
<meta property="og:site_name" content="Solene's Percent %" /> <meta property="og:title" content="How to cook without burning your eyebrows" /> <meta property="og:image" content="static/my-super-pony-logo.png" /> <meta property="og:url" content="https://dataswamp.org/~solene/some-url.html" /> <meta property="og:type" content="website" /> <meta property="og:locale" content="en_EN" />
There are more metadata than this but it was enough for my blog.
