SEO Question : 404s vs 301 redirects??
 

I'm relaunching a couple of sites and the framework is changing as well as some of the url subfolders and names. Is it better to redirect all the old pages to new pages( either pages of similar function or just the main page) or should i just create a custom 404 page where all the old pages will go. I can kindof see a valid argument for both but just wanted to get some insight on it from other SEOs.

301 to similar function pages.

it would be better, if you redirect all the old pages to the new ones!

cool so the 301 looks best, thanks.

or u could do "words/tags in old url" n forward those to search queries.
