I’ve written recently on mobile discoverability. I’ve found that the stats quoted in the article are also in evidence here on Boagworld. In fact, even more so. 65% of mobile Boagworld users hit the site directly. However, only 18% of desktop users are direct hits. All of the rest come via search engines or referrals. That is quite a striking difference.
I’d love to know what the stats are for the sites that you run. This has, potentially, huge consequences for mobile design.
