Card class: Non-Hero • Category: Device SEO

​
At a glance

Device Trend is a line chart of your organic search performance over the selected period, split by device: mobile, desktop and tablet. It shows whether clicks, impressions, CTR or position are moving differently across devices, which is the first place a mobile-usability regression or a mobile-first indexing issue shows up. Watch for one device line diverging from the others.

​
What it tracks

The card plots Device Trend for the selected period from the Search Console Search Analytics API, using the Device dimension over the date axis. Each line represents one device category, so you can see how mobile, desktop and tablet performance evolves rather than reading a single blended total. For most ecommerce sites mobile carries the majority of organic impressions, so a soft overall trend is usually a mobile trend in disguise; splitting by device makes that explicit. A mobile line that drops while desktop holds steady points to a device-specific cause: a mobile-usability error, a layout shift hurting Core Web Vitals on phones, an interstitial penalty, or a mobile-first indexing problem where Google is crawling a thinner mobile rendering of the page. Diverging CTR by device often reflects how rich results and snippet length render differently on small screens. Read the lines against your website’s organic search presence as a whole: if every device declines together the cause is site-wide (algorithm update, demand shift, de-indexing), whereas a single-device divergence narrows the investigation to that surface.

​
Reconciling against the source

Reconcile against Search Console, Performance, Search results with the Device filter applied (mobile, desktop, tablet) and the same date range. Search Console data is typically 2 to 3 days delayed and rare queries are anonymised, so very recent points may still be settling; for a clean device time series pull the data by date and device from the Search Analytics API.
