At a glance
CTR by Device breaks your organic-search click-through rate down by device: mobile, desktop and tablet. It tells SEO and content teams whether your snippets perform differently by screen, so you can fix a mobile result that ranks well but underperforms on clicks. CTR is clicks divided by impressions, expressed as a percentage.
What it tracks
This card reports CTR by Device, one bar each for mobile, desktop and tablet, where CTR is clicks divided by impressions for that device in Google organic search. The figures come from the Search Console Performance report with the Device dimension and the CTR metric enabled, surfaced through the Search Analytics API (dimensions: ["device"]). Device CTR gaps are common: a result can read cleanly on desktop yet have its title truncated on mobile, where shorter snippets and rich results crowd the screen. With most ecommerce traffic now mobile-first, a weak mobile CTR at a strong mobile position is a direct, fixable loss of organic clicks. Pair it with the device position and clicks breakdowns to separate a ranking issue from a snippet issue per device.
