Welcome to the Q&A Forum

It shouldn't make a difference. After all, you'll be optimising the Shop version for 'product name', and the main site version for 'installing product name', and the content will be different - so the two pages should really be complimenting (and linking to) each other for a mutual benefit. Duplicate content doesn't stop your best page ranking by the way. It's better to think about it as a filter - if you had two identical pages, only one will ever be found, and the other might as well not exist...

Hey there, If it's done correctly, you shouldn't see any ranking drops for longer period of time. Of course, there's always risk when you're playing with the redirecting but I'd follow the Google guidelines (as you correctly mentioned) and it should work smoothly. Let me know how it worked. Cheers, Martin

Hi. But do you not effectively get the links from the expired domain if you redirect it?

Thanks, appreciate the advice.  Im using Wordpress for the new site Im creating so Im sure theres a great tool for A/B testing.  Ill give the two options a try.  The other thing is can I have the cta too many times ont he page.  Ive got the CTA on a green button for contrast and its in the header on the right.  Ive also added it 4 times in the content after each section where I explain each benefit.  Ive also then got it at the bottom of the page too.  Not sure whether it will look a bit too spammy or the more the better?

Thanks, thats put my mind at ease

Thanks Ive sent them an email
