While sitting in line last month to get my annual auto emission test I was searching on my mobile when I noticed a tag in results “Mobile-Friendly”. I had never seen it before and recognized immediately what it meant – “Google is telling mobile users what sites are going to be a good experience to visit on your mobile”. Google's Search Engine's aim is to lead you to the best search results but it is now drawing a line in the sand and basically saying if your website is not mobile friendly (no matter how much wonderful content you have on that site) – it is not going to get the all important “Mobile-Friendly” tag. This tag in my opinion will help users decide whether they actually visit your website. And long term I suspect google may even consider listing Mobile-Friendly results first.
