Welcome to the Q&A Forum

Hi Caro, you should never have more than one version of your web. You should pick the https:// version, because a study from a important Seo Tool confirmed that the websites with https:// version perform better on Google. Then is up to you to choose with www or without. Apply redirects and when you write a different version of your site, it should always redirect to the version you chosen, at the home or at any inner page. Greetings

Hi there! Its completely correct that all those different variations have different metrics. The advice here should be: Choose the preferred version and sitck with it. Once chosen that version, redirect 301 all other variations to the other. If redirection is not possible, then use canonical tags Google does understand that you might have different versions and that you should select one and say to Google that. Authority and linkpowerness will be taken into account by google. There is also a great post from Cyrus Sheperd, stating that redirects do pass authority correctly: 301 Redirects Rules Change: What You Need to Know for SEO - Moz Blog Hope it helps. Best luck. GR
