I was researching making iphone/mobile phone friendly websites because it seems like the mobile Internet has finally taken off.  I was hoping that I could just add some css to my existing site and avoid making and maintaining a separate mobile site. I have things still on the to do list of my desktop website so how can I justify making a whole separate site just for mobile users who are still far and few between?

I saw that there was a plug-in for WordPress to automatically “mobilize” a WordPress blog and looked into that little bit.  I think this direction is the best direction because you avoid having to make another website specifically for mobile users. Installing a WordPress plug-in usually takes around 15 minutes… making a new website (  even a simple website  ) can take several hours.  I found a few WordPress plug-ins for the iPhone and mobile users in general.

Then I was thinking about the duplicate content issue… even if you copy a normal website and make several changes to it to make it mobile friendly Google might frown upon having the same information in two different places.  This turned out to be a legitimate concern.

Key phrases:
making an iPhone friendly website
using CSS to make your website iPhone friendly
mobile website template that ranks high in Google mobile search results
submitting your website to Google mobile search results
how to rank highly in Google mobile search results
mobile plugin for wordpress
What I found that was worthwhile:
