Desktop & Mobile XML Sitemap Submitted But Only Desktop Sitemap Indexed On Google Search Console

[AlisonMills]

Hi!

The Problem

We have submitted to GSC a sitemap index. Within that index there are 4 XML Sitemaps. Including one for the desktop site and one for the mobile site. The desktop sitemap has 3300 URLs, of which Google has indexed (according to GSC) 3,000 (approx). The mobile sitemap has 1,000 URLs of which Google has indexed 74 of them.

The pages are crawlable, the site structure is logical. And performing a Landing Page URL search (showing only Google/Organic source/medium) on Google Analytics I can see that hundreds of those mobile URLs are being landed on. A search on mobile for a longtail keyword from a (randomly selected) page shows a result in the SERPs for the mobile page that judging by GSC has not been indexed.

Could this be because we have recently added rel=alternate tags on our desktop pages (and of course corresponding canonical ones on mobile). Would Google then 'not index' rel=alternate page versions?

Thanks for any input on this one.

Hi Allison, any updates on this?

From my understanding, it is possible that Google is not indexing the mobile versions of pages if they are simply corresponding to the desktop pages (and indicated as such with the rel=alternate mobile switchboard tags). If they have that information they may simply index the desktop pages and then display the mobile URL in search results.

It is also possible that the GSC data is not accurate - if you do a 'site:' search for your mobile pages (I would try something like 'site:domain/m/' and see what shows up), does it show a higher number of mobile pages than what you're seeing in GSC?

Can you check data for your mobile rankings and see what URLs are being shown for mobile searchers? If your data is showing that mobile users are landing on these pages from search, this would indicate that they are being shown in search results, even if they're not showing up as "indexed" in GSC.

Apologies on the delayed reply and thank you for providing this information!

Has there been any change in this trend over the last week? I do know that subfolder mobile sites are generally not recommended by search engines. That being said, I do not feel the mobile best practice would change as a result. Does the site automatically redirect the user based on their device? If so, be sure Google is redirecting appropriately as well.

"When a website is configured to serve desktop and mobile browsers using different URLs, webmasters may want to automatically redirect users to the URL that best serves them. If your website uses automatic redirection, be sure to treat all Googlebots just like any other user-agent and redirect them appropriately."

Here is Google's documentation on best practices for mobile sites with separate URLs. I do believe the canonical and alternate tags should be left in place. It may be worth experimenting with the removal of these mobile URLs from the sitemap though I feel this is more of a redundancy issue than anything.

I would also review Google's documentation on 'Common Mobile Mistakes', perhaps there is an issue that is restricting search engines from crawling the mobile site efficiently.

Hope that helps!

Hi Paul and Joe

Thanks for the reply!

Responsive is definitely in the works...

In the meantime to answer:

• GSC is setup for the mobile site. However its not on a subdomain, its a subdirectory mobile site. So rather than m.site.com we have www.site.com/m for the mobile sites. A sitemap has been submitted and thats where I can see the data as shown in the image.

• Because the mobile site is a subdirectory site the data becomes a little blended with the main domain data in Google Search Console. If I want to see Crawl Stats for example Google advises "To see stats and diagnostic information, view the data for (https://www.site.com/)."

• re: "My recommendation is to remove the XML sitemap and rely on the rel=alternate/canonical tags to get the mobile pages indexed. Google's John Mueller has stated that you do not need a mobile XML sitemap file." I had read this previously, but due to the nature of the sub-directory setup of the site, the mobile sitemap became part of the sitemap index...rather than having just one large sitemap.

Thoughts?

ASs joe says - set up a separate GSC profile for the mdot subdomain. The use that to submit the mdot sitemap directly if you wish. You'll get vastly better data about the performance of the mdot site by having it split out, instead of mixed into and obfuscated by the desktop data.

Hi Alison,

While this is a bit late, I would recommend moving to a responsive site when/if possible. Much easier to manage, fewer issues with search engines.

My recommendation is to remove the XML sitemap and rely on the rel=alternate/canonical tags to get the mobile pages indexed. Google's John Mueller has stated that you do not need a mobile XML sitemap file.

Also, do you have Google Search Console set up for both the m. mobile site and the desktop version? It does not seem so with all sitemaps listed in the one property in your screenshot. If not, I recommend setting this up as you may receive some valuable insights into how Google is crawling the mobile site.

I'd also review Google's Common Mobile Mistakes guide to see if any of these issues could be impacting your situation. Hope this helps!
