Notice of mobile-first indexing enabled

[chms]

Hi,

I've just received a GSC message saying that in one of my websites I have enabled Mobile-first, this website almost haven't visits, someone has received this message and have noted changed in his visits?

This is the message:

"Mobile-first indexing enabled for mydomain.com

This means that you may see more traffic in your logs from Googlebot Smartphone. You may also see that snippets in Google Search results are now generated from the mobile version of your content."

Thanks

Nothing to worry about, very commonplace. Google is slowing working its way through all websites. There is no reason to worry if your website has or has not yet received this notice.

Just make sure your site is mobile friendly. Make sure it looks pretty on different small screens. Loads up very fast on small screens. Also ensure your mobile version has a strong internal link structure.

Until I got this pile of notifications in my morning's email, I hadn't realized this is something they are formally introducing, site by site. I thought all this time they'd been talking about the entire index in one fell swoop.

one of my websites

I got a total of six, with timestamps spanning two and a half hours, in this order:
https://www.example.com (canonical form)
http://www.example.com (an hour and a half later)
http://www.example.org (non-canonical name of different site)
http://example.org (canonical name)
https://example.com
http://example.com

Does anyone out there have a whole lot of sites with GSC accounts? I'm intrigued by the exact sequence: all with-www before all without-www, and https before http, regardless of actual preference. (In the case of non-https sites, I suppose you wouldn't normally even have a GSC account for the two https versions, so only the www is variable.)

Still waiting to be “notified” about my primary site, which gets at least ten times the traffic of the above two, combined. Are they rolling them out in order of GSC account creation? It isn't alphabetical order.

And it's not as if there's been any lack of mobile visitors already ...

Hi lucy24,

In that two sites, have you noted any change in your visits?

[lucy24]

have you noted any change in your visits?

Well, I just got the emails this morning, and these are not the kind of sites where changes would be noticeable in anything less than a month (aggregated).

All my sites have received that email notice, one by one, at different times over the last 6 months.

If you just got this email, it means you've been crawled for Mobile-first indexing for a while now. Indexing is completed for your site.

I'm now wondering whether they're really dragging their feet on my primary site, or if they sent the email months ago and I didn't pay attention to it. (Receiving five at once is a pretty good way to attract your attention.)

Nope, I guess not. I couldn't find it in the new version, but in the old version there's a list of messages they've sent you, most recently the Mobile First one.

I never did understand why it requires a fresh crawl. It isn't about getting new information; it's about plugging the same information into a new algorithm.

Big changes... so recrawl, re-evaluation, reindexing are needed. Some sites have a completely different version for mobile.Mobile evaluation is much different than the old desktop.

However, I would assume that if Googlebot [support.google.com] is getting 100% 301s on your previously crawled mobile or mobile-responsive sites, then old data may just be re-evaluated.
