45. EFFECTS ON SITE PERFORMANCE
Will keyword rankings be affected?
Yes, if your mobile content is reduced
and doesn’t contain terms the page was
previously ranking for on desktop.
@rachellcostello searchstarsSE
46. The most important content must be on the
mobile version.
@rachellcostello searchstarsSE
47. These need to be maintained across desktop and mobile:
MetadataContent
VideosImages
HreflangMarkup
Indexing
Rules
Alt
Attributes
Canonical
Tags
@rachellcostello searchstarsSE
48. These elements must also be crawlable and
indexable.

52. INTERNAL LINKING ON MOBILE
Be mindful of orphaned pages, or
increased levels in site depth
which could be keeping search
engines away from your content.

53. Structured data will play a vital part in the
mobile-first world, and beyond.

54. STRUCTURED DATA ON MOBILE
“The biggest challenge for mobile-first will be understanding
the lightweight needs of the user and applying this via
condensed content. Structured data and markup allows for
disambiguation when content is not so prevalent on a page in
an unstructured form.”

55. Be cautious of stripping back too far for the
mobile experience.
@rachellcostello searchstarsSE
67. FOR RESPONSIVE SITES
Make sure important resources
aren’t being blocked e.g. images, JS
& CSS.
Check for legacy issues such as
existing dynamic or separate mobile
pages - these will be indexed
instead.
@rachellcostello searchstarsSE
68. FOR DYNAMIC SITES
Check that the vary: user agent
HTTP header is in use.
Make sure the right user agent is
being served the correct version of
a page, whether that’s mobile or
desktop.
@rachellcostello searchstarsSE
69. FOR SEPARATE MOBILE SITES
Guide the mobile and desktop
user agents to the correct page
version with 301 redirects.
Make sure your servers have
capacity to handle increased
crawl rate from Googlebot
Smartphone.
@rachellcostello searchstarsSE
70. FOR ALL SITES
Test robots.txt files to make sure Googlebot
Smartphone can access your mobile setup.
Check your mobile configuration for any display
or UX issues.
Test mobile-first readiness by using SEO tools
that support mobile crawling.
