Missing twitter:card
Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

The og:title tag controls the title shown in social sharing previews.

Why this matters

Without og:title, social shares fall back to the <title> tag — usually awkwardly truncated or branded for SEO not social.

Learn more ▾

og:title controls what appears as the headline in social-share cards (Twitter, Facebook, LinkedIn, Slack, iMessage). When omitted, platforms fall back to <title>, which is usually optimized for SEO (longer, brand-suffixed) and reads badly in social context. A 50-60-character og:title gives a clean preview.

The og:description tag controls the description in social sharing previews.

Why this matters

No og:description means social cards either show no subtitle or scrape the first paragraph — usually unflattering.

Learn more ▾

Without og:description, social platforms either render no subtitle or pull whatever text appears first on the page. The first paragraph is rarely written for share-card context. A purpose-written 150-200 character og:description gives a polished card.

The og:url tag specifies the canonical URL for the shared content.

Why this matters

Without og:url, social platforms infer the canonical URL — often picking a tracking-param variant that pollutes share counts.

Learn more ▾

og:url tells the social platform which URL to count this share against. Without it, platforms use the literal URL the user pasted (which may include utm_* parameters, ref codes, etc.). Setting og:url to the canonical form keeps share-count attribution clean.

The og:type tag helps social platforms categorize the content.

Why this matters

Default og:type is 'website' but the right value (article, product, profile) unlocks richer metadata fields and higher engagement.

Learn more ▾

og:type controls which other og: fields a platform respects. og:type=article enables og:article:published_time, author, and section — surfaced in news cards. og:type=product enables price/availability fields surfaced by Pinterest and shopping integrations. Default 'website' silently disables those.

Source: Open Graph Protocol

The og:site_name tag displays the website name in social previews.

Why this matters

Without og:site_name, social cards omit the brand attribution — users see the post but not who published it.

Learn more ▾

og:site_name appears in the social card chrome (above the title in Facebook/LinkedIn previews). Without it, posts read as anonymous URLs. Set it to your brand name to get free attribution on every share.

Source: Open Graph Protocol

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

Why this matters

Without twitter:card, Twitter renders posts as plain text — no preview image, no structured layout.

Learn more ▾

Twitter requires `<meta name="twitter:card" content="summary_large_image">` (or summary) to render share-cards at all. Without it, links appear as raw text and engagement plummets vs cards. Twitter also falls back to og:image if twitter:image isn't set, so configure both.
