Compares rendered mobile and desktop versions for differences in content, links, and headings.
This check renders the page at both mobile (375px) and desktop (1280px) viewports and compares the rendered content for significant differences in text content, headings, links, images, and structured data. With mobile-first indexing, Google primarily uses the mobile version of your content.
Since Google uses mobile-first indexing, the mobile version of your page is what gets indexed and ranked. If your mobile version is missing content, headings, links, or structured data that exists on desktop, that content effectively doesn't exist for Google.
Content that only appears on desktop is invisible to Google's indexer. If important text, links, or structured data is hidden on mobile, it won't contribute to your rankings and may cause indexing issues.
