When we announced almost a year ago that
we're experimenting with mobile-first indexing, we said we'd update publishers about our progress,
something that we've done the past few months through public talks in
office hours and at conferences like
Pubcon.
To recap, currently our crawling, indexing, and ranking systems typically look at the desktop
version of a page's content, which may cause issues for mobile searchers when that version is
vastly different from the mobile version. Mobile-first indexing means that we'll use the mobile
version of the content for indexing and ranking, to better help our—primarily mobile—users
find what they're looking for. Webmasters will see significantly increased crawling by
Smartphone Googlebot, and
the snippets in the results, as well as the content on the
Google cache pages,
will be from the mobile version of the pages.
As we said, sites that make use of
responsive web design
and correctly implement
dynamic serving
(that include all of the desktop content and markup) generally don't have to do anything. Here are
some extra tips that help ensure a site is ready for mobile-first indexing:
Make sure the mobile version of the site also has the important, high-quality content. This
includes text, images (with alt attributes), and videos - in the usual crawlable
and indexable formats.
Structured data is important for indexing and search features that users love: it should be
both on the mobile and desktop version of the site. Ensure URLs within the structured data are
updated to the mobile version on the mobile pages.
Metadata should be present on both versions of the site. It provides hints about the content on
a page for indexing and serving. For example, make sure that titles and meta descriptions are
equivalent across both versions of all pages on the site.
No changes are necessary for interlinking with separate mobile URLs (m.-dot sites). For
sites using separate mobile URLs,
keep the existing linkrel=canonical and linkrel=alternate elements between these versions.
Check hreflang links on separate mobile URLs. When using
linkrel=hreflang
tags for
internationalization,
link between mobile and desktop URLs separately. Your mobile URLs' hreflang should point to the
other language/region versions on other mobile URLs, and similarly link desktop with other
desktop URLs using hreflanglink elements there.
Ensure the servers hosting the site have enough capacity to handle potentially increased
crawl rate. This
doesn't affect sites that use responsive web design and dynamic serving, only sites where the
mobile version is on a separate host, such as m.example.com.
We will be evaluating sites independently on their readiness for mobile-first indexing based on
the above criteria and transitioning them when ready. This process has already started for a
handful of sites and is closely being monitored by the search team.
We continue to be cautious with rolling out mobile-first indexing. We believe taking this slowly
will help site owners get their sites ready for mobile users, and because of that, we currently
don't have a timeline for when it's going to be completed. If you have any questions, drop by our
Webmaster forums
or our public events.
