Squarespace OG Image Not Showing? How to Fix Social Previews

Why Squarespace OG images fail

Squarespace automatically generates Open Graph tags from your site content. However, the image it picks is often wrong — too small, the wrong aspect ratio, or just the site logo. The most common culprits:

• No thumbnail set for the page or blog post
• Thumbnail image doesn't meet platform minimum dimensions
• Stale platform cache from before you added an image
• Social image header code block not configured in SEO settings

Fix 1: Set a thumbnail per page

Squarespace uses each page's Thumbnail image as the og:image. In the Squarespace Editor:

1. Click on the page (or blog post) you want to fix in the left navigation panel.
2. Click the gear icon (page settings) → SEO tab.
3. Under SEO Image (or Thumbnail in the main tab), click Add image and upload a 1200×630 px image.
4. Save the page settings and re-publish.

Fix 2: Set the site-wide social image

For the homepage and pages without a specific thumbnail, Squarespace falls back to the site-wide social sharing image:

1. Go to Settings → SEO.
2. Scroll to Social Sharing Logo & Image.
3. Upload a 1200×630 px image under Social Sharing Image.
4. Save.

Fix 3: Blog post thumbnail

For Squarespace blog posts, the og:image is drawn from the post's thumbnail:

1. Open the blog post in the editor.
2. Click Post Settings (gear icon).
3. Under Thumbnail Image, upload a 1200×630 px image.
4. Save and re-publish the post.

If there's no thumbnail, Squarespace will use the first image in the post body, which may be the wrong size or orientation.

Fix 4: Clear platform cache

After updating images in Squarespace and publishing, force each platform to re-fetch:

• Twitter/X: Twitter Card Validator
• LinkedIn: LinkedIn Post Inspector → Inspect → Scrape again
• Facebook: Facebook Sharing Debugger → Scrape Again (repeat 2–3 times)

Squarespace OG tag limitations

Like Wix, Squarespace controls your HTML and doesn't allow raw <meta> tag injection into page heads without a workaround (code injection via Settings → Advanced → Code Injection, available on Business plan and above).

If you need per-page custom OG tags, use the Page Header Code Injection field (page settings → Advanced) to add custom meta tags that override Squarespace's defaults.
