The launch of a Mobile Site

I have always liked the idea of a mobile site, and my previous job I created a great Mobile version of their existing site. It had logins, pretty colors, anchor links, mobile access key links so you could press a button to activate links. It wasn’t until the launch of Inside AdSense: Here comes mobile that I have even considered porting one of my biggest sites to a mobile version.

In a perfect world you can have one style sheet for a browser, and a mobile style sheet for a mobile. But in reality it just doesn’t work. The amount of content for a phone has to be considered, visual real estate is also another. One thing is users are going to have to click a lot on a mobile phone to view the content. So you got to make what gets shown count.

Some problems I have seen is clicking down on a phone goes to the next link, so if you have lots of links, the point of link focus can go all over the place. I liked the idea of “down arrows” that will take you to the next section of the page, I try to keep the pages shot (like 10 cms long).

So now that I created the mobile site, how do I SEO it? How do I promote it? Should I worry about it being indexed in the main Google site, thus causing a potential duplicate content problem?

First things first : Create the site maps.
Problem is I did this for almost 30,000 “Main” pages. Each of these pages can have between 1 to almost 300 other links. That’s a lot of pages and even though the html contains :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">


My HTTP headers are sending
Content-Type: text/html; charset=utf-8

This could be a problem, so I need to check if it can accept the application/xhtml+xml header and send that.
I really should fix this, and can see how I get crawled.

Next step is the site needs a site map link, its not really for the users, but more of the crawlers. The pages should really leak to others.

Next step is to make a link to the site map in the robots.txt file
Next is to submit them to the Yahoo Site Explorer and Google Webmaster tools.

I did this about 4 days ago, and in today’s logs I have noticed :

Now spending all this time creating 2 versions of a site, you get to see potential problems

Mobile Web developers irate at Vodafone move

Vodafone UK is abusing its position

This is all I need,
And the fact that with the Google Adsense on the mobile, is the site has to hit google for the link data (only after allowing fopen (gulp)) Then the page gets displayed, and then Google ad bot hits the site.

As for Google Mobile Adsense : Page impressions, it counts the yahoo bot hitting your site. So if you see a big spike there, now you know.

Well time to monitor the logs and wait for the mobile feedback.
