Thanks for the thoughtful reply, Samuel. Definitely some good questions, and a few I hadn't already asked myself. I've made an effort to save press releases where there is definite long tail value. I also agree that point #2 about institutional knowledge is a big one. There are about 1,500 pieces of content in the audit and maybe 1/5-1/4 of that is press releases (dating back as far as 2006), so I won't have time to check all of them for external links, but that's definitely something I hadn't thought about, so I might have to figure out how to work some of that into the timeline. Thanks again.

Howdy Moz Community,

I'm working with a client on migrating content to a new site/CMS and am wondering whether anyone has thoughts on the value of old press releases. I'm familiar with the devaluation of press release links from early 2013, but I'm wondering more about their value as content. Does importing old press releases (3-5 years old) create contextual depth of content that has some value for the site as a whole (even though the news contained within is useless)? Or, do these old press releases just create clutter and waste time (in migration). The site has a wealth of additional content (articles and videos), so the press releases wouldn't be covering up for thin content. I'm just wondering whether there's any best practices or a general rule of thumb.

Thanks!
