43. Tag Pages with Canonical
Markup
What Google says…
• Canonical markup helps make content visible to bots
and searchers
• If you have an “m.” mobile site:
• Each desktop page should contain a "rel=alternate"
link meta tag that points to the mobile URL
• Each mobile page should contain a "rel=canonical"
meta tag that points to the desktop URL
• Alternatively add notation to Sitemaps file
• Consider Javascript redirects that match on link value
45. Some Best Practices
• Follow
the
"m"
convenYon
(m.novarelibrary.com
OR
lifeonterra.com/m/)
• Keep
categories
(directories)
short.
Remember
that
you
are
creaYng
a
page
that
people
touch
without
much
typing
• Limit
image
and
markup
sizes
• Limit
HTML
pages
to
25KB
to
allow
for
caching
• "Minify"
your
scripts
and
CSS
(JSLint,
CleanCSS)
• Link
to
Full
Site
• Sniff
for
User
Agent
–
DetecYon
(allow
the
user
to
decide
where
to
go)
• One
Column
Layout
with
some
whitespace
• Mobile
refers
to
the
user!
46. MOBILE SEO TIPS
• SEPARATE URLS?
• On the desktop page, add the link rel=”alternate” tag pointing to
the corresponding mobile URL. This helps Googlebot discover the
location of your site’s mobile pages.
• This tag specifies an alternative URL to the desktop page.
• <link
rel="alternate"
href="hGp://m.example.com/"
/>
• On the mobile page, add a rel=”canonical” tag pointing to the
corresponding desktop URL. This rel=”canonical” tag on the mobile
URL pointing to the desktop page is required as it signals the
relationship between the two URLs
Ø <link
rel=“canonical”
href=hGp://www.example.com/”
/>
*maintain a 1-to-1 ratio between the mobile page and the corresponding
desktop page
