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:image tag provides a preview image for social sharing.

Why this matters

No og:image means social shares are imageless — measurably less engaging than image-cards across every major platform.

Learn more ▾

Twitter, Facebook, and LinkedIn all use og:image (or twitter:image as a fallback) for share-card thumbnails. Without one, the post renders as a text-only card. A 1200x630px image (Twitter's preferred size) covers all platforms.

URL: 218 chars

Descriptions over 200 characters may be truncated in social sharing previews.

Expected: 55–200 chars
Why this matters

og:description borderline-too-long — social platforms truncate around ~200 chars.

Source: Open Graph Protocol

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.

Source: Open Graph Protocol

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.

Missing recommended property "logo" for Organization
Adding "logo" can improve how search engines display your content.

Adding "logo" can improve how search engines display your content.

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Learn more ▾

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.
