Google’s priorities are not always the same as mine. Trust, security, compatibility, and safety are all important, and the terms are sometimes used somewhat interchangeably.
Trust and Safety
This is about as safe a site as you will find. Everyone is free to come here. No account or password is required. There’s no advertising, and I’m not selling anything.
Thanks to that, the search engines and browsers haven’t cared that a secure connection isn’t created when you visit here.
Norton Safe Web has dubbed the site SAFE, without threats or even “annoyance factors.” That doesn’t mean nobody will be annoyed by anything they find here. Norton defines annoyance factors as “Items that don’t necessarily do harm, but are a nuisance, such as joke programs or a site that isn’t what it seems.”
If your site isn’t friendly to mobile devices, your potential customers may go elsewhere. Even existing customers may be tempted by the web sites of your competitors.
Apps Can’t Do Everything
Your web site needs to work with mobile devices. Smaller companies, and those that don’t regularly interact with their customers online via their mobile devices, may not even have an app. People who want to find out more about the company or the products will still need to use your web site, so it had better work well with mobile.
