About this link preview
Duolingo (duolingo.com) is filed under Business in the LinkPreview gallery. Its meta title is just 8 characters, well short of the 50–60 that usually show in full on Google, so there is room to add a keyword or a clearer promise. The description runs 148 characters, inside the 140–160 sweet spot for search snippets. The Open Graph image is 1200 × 630 pixels, the standard size for X, LinkedIn, Slack and WhatsApp cards.
