Im currently working on redesigning a site done in ASP over to PHP. The old ASP pages have been coded with a 301 redirect and point to the new PHP page. However, I realized that I've removed any links on the site to these old ASP pages. My question is, do the spiders NEED to follow a link to the old ASP page in order to get the 301 or does that not matter? TIA to anyone who answers.
