No Twitter Card meta tags

Twitter Card meta tags are short code snippets in your page's HTML that control how your pages appear when shared as links on X (formerly Twitter) — determining whether a link shows as a plain URL or as a rich card with image, title, and description. These tags were not found in your server-delivered HTML. (If your site uses JavaScript to load content, they may be present after the page fully loads — worth checking.) Without Twitter Cards, links to your site shared on X appear as bare URLs with no visual preview. Rich cards get significantly more clicks than plain links. Add the standard Twitter Card meta tags — at minimum twitter:card, twitter:title, and twitter:description — to the head of each page. If you already have Open Graph tags for Facebook/LinkedIn, Twitter Card tags require only a small addition.
