Rationale behind a
mobile site

How we made ours

Optimization tricks

Why?
33% mobile penetration
in India by 2011

400 million people,
25-50 million with
Internet on the mobile.

Over 50% of them would
only use
Internet on the mobile.

We made our site using
stuff we were familiar
with. PHP, Symfony,

and in
2 weeks.

Optimization: Images

Animated,
mobshare.in Interative,
Large
banner 100KB

m.mobshare.in Text,
Static,
banner <1 KB Tiny

Bandwidth is expensive
10paisa/10KB

Optimization: CSS

CSS size of mobshare.in
> 85KB

CSS size of m.mobshare
< 3KB, all inline

Optimization: Requests

As fewer domain names
as possible

Mobshare.in
8-12 domains,
*.cdn.mobshare.in

m.mobshare.in
1 domain, 1 direct IP

Direct IP?
DNS resolution on a
mobile is really expensive

http://67.207.130.241/
index.php?asset

Our Open Source tool:
nginx-asset-hot-cache:

Keep content focused.

Optimize for specific
mobiles.
