This strikes my curiosity.
I have two versions of my website. A desktop version and a mobile version. The objective of both websites is to allow users to view whatever full size photos they like to see.
On the desktop version of the site, I fill it with a lot of helpful text detailing each extra option one can do with a photo such as ordering it, etc.
On the mobile site, I have it very basic. Maybe a sentence describing a photo and the photo and that's it.
People say content is king and I think the minimum number of words per page should be 250 to avoid a thin-content penalty. So far, I have not received that on the mobile site from google webmaster tools, yet I never submitted a sitemap to the mobile site. I only submitted one for the desktop site.
The reason why I make the mobile version mostly stripped down is because I want users to spend less money on bandwidth and paragraphs can eat bandwidth, especially if they're decorated.
So with that set aside, is there a different minimum required word limit for mobile sites in comparison to desktop sites in order to evade google's thin-content penalty?
The average age group of users visiting my site range from about 18 to 24 and younger people cannot afford a lot of money.
