We have an old website. Which long time did not get an update, nor content. Many websites copied our content. And we might have some penalities now.
We are starting a completely new related website, with unique content and so on. And i am trying to get some ideas how to use an old website. And i don't want any of an old website product to get on the new website.
1 Option. New website on old domain. Old website content stays the same, but it will not have any links to it in the website. Old content would stay only for the purpose for landing from Google. All following pages for browsing would be new content. So my plan is that google would naturally de-index old pages. And they will be gone. In this case we would use existing old traffic to drive a new content website. (If there are no penalities on domain, it would be good). How long will take for google to de-index all low quality pages?
2 Option. New website goes on new domain. We would use plugs to add new website content to an old website. Visitors are mostly landing in one type of pages in the old website. So we would not put new website plugs to thee landing pages. (most important pages are not these landing pages - they were only the google favorite, but not the main website content ). So we would add plugins to the main website content, search results etc, and would redirect visitors who are most loyal and has biggest time one site stats.
3 Option. New website goes on new domain. All old website pages are redirected to the new website. If product page is the same, and exists on new website - it would be redirected to the new website page. If product does not exist on new website - old one will redirect to some folder /product/title - it would show old website content added to a new web, but would be non-indexable by google (automatically gets deindexed from an old website, but after some time).
Any comments on my options? Any perfect suggestion?
