Welcome to WebmasterWorld Guest from 188.8.131.52
The former owner had the page for this domain-name full of content about "searching for green widgets";
"better searching for green widgets", etc., etc..
Our new site has absolutely no content related in any fashion to thiese terms/phrases. The new content is as different as night and day.
While we were shifting the copy arond, building the site I added <nofollow,noindex> & <noarchive> robot meta tags to keep crawlers from indexing incorrect terminology (the product is a first w/ a variety of pending patents) but Gbot still indexed all of the new pages, although with no snippets, cached links, etc.
Nonetheless - a current 'site:www.newcontent.com' search, & clicking on the "Similar pages" link under each new page Gbot has now indexed under www.newcontent.com, shows the "related:www.newcontent.com" SERPs are still 100% about the old domain's content; "searching for green widgets", etc.
We're about to change all the existing file names for all of the site's pages; then use the Remove URL tool
and let Gbot find 404's for all the pages it has indexed under the new www.newcontent.com.
Will this flush the pages Google has cached as "related:"? Or is there something else that needs to be done?
