Like many webmasters, I got notice from Google that my sites are not mobile-friendly. Touch elements too close, viewpoint not configured, and small font size.
I am a content person, not a web designer. I am not going to redesign my sites myself and I don't particularly care if I have unique designs (the content is unique, and that's what I care about.)
The other day I found a website with some design templates that I like. (Which is unusual, because in the past when looking for designs for sale most I came across have been graphics heavy and my sites have very few graphics.)
The website claims the templates are "fully responsive". So I converted several of my sites.
Question: how do I know the new designs will satisfy Google's criteria?
I don't want to proceed to modify all my sites, including the big ones, only to find Google still doesn't like them.
Is there a place I can go to test my sites for Google's mobile friendliness?
P.S. I don't have a smart phone and never use the web from a tablet or mobile device, but I am sure many visitors do.
