Welcome to the Q&A Forum

Hi Howard Both Joseph and Gaston's tips here are great. Just adding that for backlinks, you could choose a handful of your most authoritative/important backlinks and ask the sites to update the link. It's probably not super needed from a ranking standpoint, but can help Google pick up on the migration signals faster - and I find it's actually a great reason to reach out to sites and reconnect. Definitely update any backlinks you have control over (in social, profiles etc) I definitely recommend following Aleyda's checklist that Gaston linked to.

Thank you Gaston.  Anyone have any input regarding SSL certificates and submitting various url versions to Google Search Console. My certificate is only for a single url so should this be the site that I specify to GSC. Volusion does not allow wild card or multi-site ssl certificates. I'm a little confused as to what is the best way to proceed. The older non secured url version is the one with a long analytics history.

Hi Ben,Where do you add the 'rel="nofollow"'? I can't seem to find it.

i assume you are hosted on IIS, you can use iis url-rewite model to fix this. Match ^/default.asp$ rewrite to / But the main thing here is that you have a link on your site somwhere thet points to default.asp. or the crawler would not of found it. Best to fix it for good, but if no links point to it, then it will never apear in the address bar, then no one will copy and paste a link to it and you will more then likley nver have a problem

Thank you for a great informative response.
