Google Discover SEO Checklist

Imagine waking up to a massive spike in traffic without spending a dime on ads. That's the power of Google Discover. Unlike traditional search, Discover proactively serves content to users based on their interests. And for Discover, your images are the most important factor.

If your visuals don't meet Google's specific technical and quality requirements, your high-quality content will never see the light of day. In this guide, we provide a proven checklist to optimize your images for maximum visibility.

The #1 Rule: High-Quality, Compelling Visuals

Google explicitly states that to be eligible for Discover, your content must use high-quality images. But 'high quality' isn't just about resolution; it's about engagement. Your image should be clear, relevant, and compelling enough to make a user stop scrolling.

Pro Tip: Large images are much more likely to generate clicks from Discover. Google recommends that your large images be at least 1200 pixels wide.

The Google Discover Image Checklist

To give your articles the best chance of appearing in the Discover feed, follow this technical checklist for every featured image:

1. Mind the Dimensions

  • Minimum Width: 1200 pixels. Small thumbnails are often ignored by the Discover algorithm.
  • Aspect Ratio: Use compelling 16:9, 4:3, or 1:1 ratios. Landscape images (16:9) tend to perform best in the mobile feed.

2. Optimize for Speed

Discover is a mobile-first experience. If your 1200px image is several megabytes in size, your page will load too slowly, hurting your chances. Use our Compress tool to shrink your file size while maintaining crystal-clear quality.

3. Use Modern Formats

While JPG is standard, modern formats like WebP provide better compression and faster load times. Converting your high-res originals to WebP is a smart move for mobile SEO.

4. Add Proper Metadata

Ensure your images have descriptive alt text. This helps Google understand the context of the visual and how it relates to the user's interests.

Leveraging Structured Data (Schema.org)

Technical SEO doesn't end with the image file itself. Using JSON-LD structured data is a powerful way to signal to Google that your content is a high-quality article or tool.

By including the SoftwareApplication or Article schema, you provide Google with explicit details about your content, making it easier for their AI to match your post with the right audience.

FAQ

How do I know if my image is on Google Discover?

You can check your performance in Google Search Console under the 'Discover' report. This will show you exactly which pages and images are appearing in users' feeds.

Is there a specific file size limit?

While there's no hard limit, images under 100KB are ideal for mobile performance. Anything over 300KB might slow down your page enough to be disqualified from top positions.

Can I use stock photos for Google Discover?

Yes, but original, high-quality photography usually performs better. If using stock photos, try to choose unique ones and optimize them so they don't look like generic templates.

Does the image alt text matter for Discover?

Yes. Alt text helps Google's machine learning algorithms understand what the image represents, which is crucial for matching it with user interest categories.
