How to Fix: OG image 1200×630

OG image 1200×630 is an important SEO check in the Image SEO category. This is a high-priority SEO issue that should be addressed soon. It has a significant impact on your SEO performance.

What is This Check About?

This check verifies that your pages declare an Open Graph image at the recommended 1200×630 pixels — the size that renders cleanly as a large, clickable card when your link is shared on Facebook, LinkedIn, Slack, and most messaging apps. The og:image tag, and its 1.91:1 aspect ratio, is what decides whether a shared link shows a crisp full-width preview or a sad little cropped thumbnail. The check fails when the tag is missing, points at a wrong-sized image, or resolves to something that gets awkwardly cropped.

Why Does This Matter for SEO?

This is a social and click-through signal more than a direct ranking one, and it earns its high priority because:

• A correctly sized preview card gets dramatically more clicks than a bare link or a broken thumbnail — the image is the first thing anyone sees in a shared feed
• Those clicks and shares drive the referral traffic and engagement that support your rankings indirectly
• A wrong-size image gets cropped unpredictably across platforms, often chopping your logo or headline in half and making your brand look careless
• It is a ten-minute fix with an outsized effect on how every future share of your content looks

How to Check This Issue

You can identify this issue by:

1. Viewing a page’s source and confirming an og:image tag exists, points to a real image, and ideally declares og:image:width 1200 and og:image:height 630
2. Pasting the URL into a social debugger (such as a sharing preview or link-inspection tool) to see exactly how the card will render
3. Checking that the image is 1200×630, an appropriate file size, and reachable at a public URL (not blocked or behind login)
4. Running an SEO audit with the SEO Roadmap tool to list pages missing or mis-sizing the OG image at once

How to Fix This in WordPress

Difficulty Level: EASY – This fix is straightforward and can typically be completed by anyone with basic WordPress knowledge.

Estimated Time: 10 min

Set a good site-wide default, let key pages override it, and hit the spec exactly.

Step 1: Set a default OG image in your SEO plugin

Yoast SEO, Rank Math, and SEOPress all have a social settings panel with a default Open Graph image. Upload one that is exactly 1200×630, with your logo and any text kept well inside the frame so cropping on odd platforms never clips it. This single default immediately covers every page that has no image of its own.

Step 2: Give important pages their own image

For cornerstone content, products, and pages you actively promote, set a per-page social image in the plugin’s post-level social tab — again at 1200×630. A tailored card outperforms a generic one for anything you care about people sharing. Many plugins will fall back to the featured image, so make sure your featured images are large enough not to be upscaled into mush.

Step 3: Verify the Fix

After making changes:

1. Clear your WordPress cache if you’re using a caching plugin
2. Re-run the URL through a social debugger and force a re-scrape so the platform drops its cached old preview
3. Re-run the SEO Roadmap audit to confirm the issue is resolved
4. Check Google Search Console after a few days to ensure Google has recognized the fix

Why hitting the exact spec is the whole job

Let me tell you where I first learned that a spec is not a suggestion. My first paid job, back in 1990, at fourteen, was showing a print shop how to lay out reverse type on vellum. On that job you did not get to be roughly right. If the artwork was off by a hair, the reverse read wrong, the registration slipped, and the whole run was scrap — expensive scrap, with someone standing over you asking why. The shop paid me in pocket money and a soft drink, and could not quite believe a kid with an Apple at home understood their production spec better than they did. What they were really paying for was someone who treated 1200×630 — or whatever the equivalent was that day — as an exact number, not a vibe.

The OG image is the same discipline in a modern skin. “About that size” is what produces the cropped, off-center card that makes a business look amateur in every feed it lands in. Exactly 1200×630, safe margins on the text, the logo clear of the crop line — that is what produces a card that looks deliberate everywhere it appears. The medium changed completely since 1990. The lesson did not: with production specs, precise is the only setting that works.

• Pointing og:image at an image behind login or otherwise not publicly reachable
• Forgetting to force a re-scrape, so the old cached preview keeps showing
• Not verifying the fix was successful after implementation
