If you share links to your website via Social Media (Facebook, Twitter, Google+) you need to be ready for mobile visitors.
First thing in the morning, as I wait for my first cup of coffee to hit my bloodstream, I’m on my phone. First, I go through email and answer anything urgent. Then, over to Facebook and catch up on what happened while I slept. And finally, I’ll open TweetDeck and go through my Twitter feed.
When I see a story I want to read, and click through, many times the linked site doesn’t have a mobile version of their site. When this happens, I end up going back and favoriting the tweet to read later. But making your site mobile-friendly isn’t difficult. In fact, if you use WordPress, you can have it done in less than 5 minutes.
