We've recently built a site for a new client who has not inserted all the content that they had from their old site into their new one. Also a lot of content is dynamic with ID's not matching from the old site to the new one.
We have added dynamic redirects for most of the patterns we could find in pages that were 404ing, but there are still a lot of pages that had content, or just jumbled urls that we cannot match up with content pages on the new site.
Is it better to redirect these leftover pages to the homepage? Or leave them 404ing?
