Hey Guys, Long story short here, had a domain, built backlinks (main domain and sub pages), it got penalised (manual penalisation?) by G (GWT has noticed unnatural blah blah). Cleaned up all the crap links, after about 4 submissions to G, it got unpenalised and no longer listed under GWT. Having said that, I think there are still some algorithmic penalties going on for my site. In specific, some URLs seem to be ranking lower than they should. Having said all that. I am now building a new site with a new site structure (same domain). Question: Should I forward the old urls to the new urls, or should I just show a generic 404 page with a link to the main domain (and/or redirect them to the main domain). Reason I ask is if there any 'bad mojo' on the old urls, I dont want that to get forwarded to the new urls. PS: This is a legitimate company site in operation for over a decade, not some fly-by-night site. Your thoughts?
