I have been creating html sites for 13 years now. Recently, I have been getting emails from Google that warns me that the site isn't mobile friendly. I know that. I had one client tell me that they "heard" that Google will be reprimanding sites that haven't converted to mobile friendly by April. Is that true? I know it is a good idea to be mobile friendly but some of my clients either aren't interested or can't afford to convert their site right now. Please advise if this is a scare tactic or if it is legit.
