Google Search Console Mobile vs Desktop: How to Compare Device Performance

Most sites get more than half their impressions from mobile, yet many SEOs analyze Search Console data without ever breaking it down by device. The result: you optimize for an average that describes nobody.

This guide shows you how to filter Google Search Console by device type, what to look for when you compare mobile vs desktop performance, and how to act on what you find.

Why Device Segmentation Matters

Google Search Console's default Performance report aggregates clicks, impressions, CTR, and average position across all devices. Desktop queries and mobile queries get averaged together, which can mask big differences in how your pages actually perform.

A page might have a 4.2% CTR on desktop but only 1.8% on mobile. If you average those, you get something like 2.7% and walk away thinking the page is mediocre across the board. In reality, you have a mobile CTR problem that a rewritten meta description could fix.

Device segmentation is how you find those problems.

How to Filter by Device in Google Search Console

The filter is in the Performance report's top toolbar, next to the date range selector.

1. Open Google Search Console and go to Search results under the Performance section.
2. Click + New in the filter bar above the chart.
3. Select Device.
4. Choose Desktop, Mobile, or Tablet and click Apply.

The chart and the data table below it will now show only that device's data. You can apply the filter while grouped by Query, Page, Country, or Search Appearance -- all of them respond to device filters.

To compare two devices side by side, use the Compare tab instead of the Filter tab:

1. Click the Date selector.
2. Switch to the Compare tab.
3. Under Dimension, select Device.
4. Choose which devices to compare and click Apply.

GSC will draw two lines on the chart and add delta columns (Difference and % Change) to the data table, so you can see which pages gained or lost ground between the two device types.

What to Look For: Four Useful Analyses

1. Pages With a Big Mobile/Desktop CTR Gap

Sort the Pages tab by CTR after filtering to Mobile. Then run the same filter for Desktop and note the pages where the numbers diverge the most.

A page that ranks position 3 on desktop with a 6% CTR but position 3 on mobile with a 2% CTR is worth investigating. The title and meta description that look good on a wide browser may be getting cut off or outcompeted by richer snippets on a mobile SERP.

Search Console Tools makes this comparison faster by letting you pull both views and sort them without toggling back and forth manually.

2. High-Impression Mobile Pages With Near-Zero CTR

Filter to Mobile, sort by Impressions descending, then look at CTR. Pages with thousands of mobile impressions and a CTR below 1% are your highest-leverage optimization targets.

The fix is usually one of three things:

• The title is too long for mobile search results (aim for under 60 characters)
• The meta description doesn't match the mobile searcher's intent
• A featured snippet or AI Overview is capturing the click before it reaches your result

3. Desktop Queries You Are Ignoring

Filter to Desktop and sort by Impressions. Many sites under-invest in desktop because mobile gets all the attention, but high-value commercial queries often convert better on desktop. If you see high-impression desktop queries where your average position is in the 10-20 range, those are worth targeting with dedicated content.

4. Position Divergence by Device

Google's ranking algorithm is not identical for mobile and desktop. Use the Compare view to look for queries where your average position is significantly different between the two. A page ranking position 6 on desktop but position 14 on mobile may have a Core Web Vitals issue, a mobile layout problem, or missing mobile-first indexing signals.

Cross-reference these queries with the Core Web Vitals report and the Mobile Usability report in Search Console to find the root cause.

Tablet Data in Search Console

Tablet gets its own device type in Search Console, but most sites see very little tablet traffic. Unless you have a reason to focus on tablet -- a specific app or tablet-optimized tool -- you can mostly ignore it. When you do see high tablet impressions, they often behave more like desktop than mobile, since tablets use wider viewports.

Common Mistakes When Analyzing Device Data

Comparing raw click counts instead of CTR. Mobile almost always drives more impressions than desktop for most sites, so comparing absolute clicks is misleading. Use CTR and average position when comparing device performance.

Filtering to mobile and then exporting the full 1,000-row default. Search Console caps exports at 1,000 rows per query. If you have a large site, use the GSC API or a third-party tool to pull more rows without the cap.

Treating "position" as the whole story. Average position in GSC is the mean position across all impressions for that page and query. A page that sometimes appears at position 1 and sometimes at position 10 will show an average position of about 5. Use it as a signal, not a precise rank.

Forgetting the data delay. Search Console data is typically delayed by a few days. When you filter by device and see a sudden drop, check whether it falls within the usual data delay window before treating it as a real signal.

A Simple Device Audit Workflow

Here is a process you can run monthly:

1. Open the Performance report and filter to Mobile.
2. Set the date range to the last 28 days.
3. Sort the Pages tab by Impressions descending.
4. Flag any page with more than 500 mobile impressions and a CTR below 2%.
5. For each flagged page, check whether the title is under 60 characters and the meta description is between 120 and 155 characters.
6. Rewrite the ones that are too long or that read better for a seated desktop reader than a mobile user searching on the go.
7. Submit the updated URLs to Bing Webmaster Tools for quick re-crawl.
8. Repeat for Desktop, flagging pages with more than 500 impressions and a CTR below 3%.

This takes under an hour once a month and consistently surfaces pages worth optimizing.

Connecting Device Data to Page Speed

The most common reason for a mobile/desktop ranking gap that you cannot explain through content differences is page speed. Google's mobile index weighs Core Web Vitals more heavily for mobile rankings.

If you find a page that ranks position 5 on desktop but position 18 on mobile, run it through the Core Web Vitals report in Search Console. If the page has poor LCP or high CLS on mobile, fixing those will often close the ranking gap.

A fast mobile page with an optimized title and description can go from 1.5% mobile CTR to 4% or higher. At scale, that is the difference between a site with flat traffic and one that grows every month.

Doing This Faster With Search Console Tools

Toggling device filters manually in Search Console, writing down numbers, switching back, and comparing is slow. Search Console Tools pulls your GSC data via the API and lets you see mobile vs desktop CTR side by side for every page, sortable and filterable without the manual back-and-forth.

The dashboard highlights which pages have the biggest mobile/desktop gap so you can prioritize without building your own spreadsheet.

Summary

Filtering Google Search Console by device takes about five seconds. What you find can reshape your optimization priorities for the next quarter. The process:

• Use + New > Device to filter to a single device type
• Use Compare > Device to put two devices side by side in one view
• Look for pages with large CTR gaps, high mobile impressions and low CTR, and position divergence between devices
• Cross-reference mobile ranking gaps with Core Web Vitals and Mobile Usability data
• Run the monthly device audit to keep your title and description length in check for mobile SERPs

Device data is one of the most underused dimensions in Search Console. Most of your competitors are not looking at it. That is exactly why it is worth your time.
