In my site there will be a lot of pages that have a short life span of about a week as they are items on sale, should I nofollow the links meaning the site has a fwe hundred pages or allow indexing and have thousands but then have lots of links to pages that do not exist. I would of course if allowing indexing make sure the page links does not error and sends them to a similarly relevant page but which is best for me with the SEarch Engines? I would like to have the option of loads of links with pages of loads of content but not if it is detrimental
Thanks
