This question came about because of an issue with an SSL certificate on iOs. Basically, when you are on (in this case) an iPhone running iOs 12 and you go to the home screen search (spotlight? swipe left home screen search) and search for 'PHmuseum' our website appears within 'Siri suggested websites'. But the URL used is
www.phmuseum.com and our website uses
www exists in DNS and we have a 301 redirect for it. I've recently corrected the SSL certificate to include
www as iOs shows an error even on a 301 (which Chrome doesn't).
Where do these search results come from? It doesn't seem to be Google. Does anyone know how to manage these results for your website? I'd like to remove the
www and explore other optimisations.
