-------------------------------------------------------------------- NOTES -------------------------------------------------------------------- This is deliberately short. Your theme already outputs og:title, og:description, og:url, og:site_name, twitter:card, twitter:title and twitter:description through the social-meta-tags snippet, and it already outputs a canonical tag. Adding those again would duplicate them, and the browser takes the first one anyway. The two things it does NOT do: 1. There is no robots meta anywhere. Adding max-snippet:-1 and max-image-preview:large    tells Google it may quote the full answer block and show the diagram large. That is    what wins the AI Overview and the image result. 2. social-meta-tags only emits og:image for products and for articles that have a    featured image. Pages get no image at all, so the guide pages currently share as a    bare link. The block above fixes that for the two guide pages. Once the diagram PNG is uploaded to Shopify Files, replace all three instances of REPLACE_WITH_DIAGRAM_CDN_URL with its CDN URL. Until then, leave the second block out. For the touchmark post, set a featured image on the article and the theme handles the og:image on its own. Nothing to add.
