Open Graph

Action

Open Graph tags need attention — social sharing previews may be incomplete.

FIX

Open Graph tags need attention — social sharing previews may be incomplete.

Missing og:description

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

og:title is short (7 characters)

Ideal length is 25–60 characters for social sharing previews.

Got: 7 chars Expected: 25–60 chars

Missing og:url

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

Missing og:type

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

Missing og:site_name

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

Missing twitter:card

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

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.

URL: 7 chars

Ideal length is 25–60 characters for social sharing previews.

Expected: 25–60 chars

Why this matters

og:title very short — may render with awkward whitespace in social cards.

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.

Image Optimization

Action

3 issues found across 7 images

FIX

3 issues found across 7 images

7 images missing explicit width/height

Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.

7 below-fold images missing loading="lazy"

Lazy loading defers below-fold images, reducing initial page weight.

7 images missing alt text

Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.

No Organization schema — Google can't render your logo in the knowledge panel

No structured data (JSON-LD) found

Adding structured data helps search engines understand your content and can enable rich results.

Why this matters

Without schema.org markup, your pages can't appear as rich results (stars, FAQs, recipes) in search.

Learn more ▾

Structured data is what unlocks rich snippets — review stars, FAQ accordions, recipe cards, breadcrumbs, etc. — that take up more SERP space and dramatically improve click-through. The schema.org vocabulary is well-documented and JSON-LD is the easiest format.

No structured data found

Structured data (JSON-LD) helps search engines understand your content better. Adding it can improve your search result appearance.

Common types include:

WebSite — your site identity and search box
Organization — your company information
Article — blog posts and news articles
Product — e-commerce product pages
BreadcrumbList — navigation paths

Rich Results Eligibility

Action

No JSON-LD found -- no rich-result eligibility

REVIEW

No JSON-LD found -- no rich-result eligibility

No JSON-LD structured data on the page

No `<script type="application/ld+json">` blocks found. Without structured data, search engines fall back to inferring page meaning from raw HTML -- which works but doesn't unlock SERP features (rich snippets, knowledge panel, FAQ accordion, breadcrumb trail). Adding even basic JSON-LD (Organization for the site identity, BreadcrumbList for navigation context) is a low-effort SEO win.
