MOving from one page format to another

[kevgrand]

I have a page that I optimized for a valuable keyword (at least it is to me!) and it gets very good traffic. Problem is that the page needs to constantly updated with new "news" related to the topic area. I have developed a page-type that will have the same static content as the original page, but it will now automtaically index related content from the rest of the site so the "news" section stay fresh and up-to-date. I am now okay to do something like permanently redirect that page to the newly built one? I have also run the newly designed page through tests on Moz and it receives on receives an A-grade from the on-page optimization tool.

I am just wanting to ensure I cover all bases, because I do not want to risk losing the top search result and all that valuable traffic.

If I understand correctly, you're ranking well for a page and related keywords but you'll be adding new "news" content related to the title page topic. Sounds good to me. I'd make sure to note my changefreq in the sitemap to hourly or daily. While I'd expect you to continue to rank well for your static content, there are other factors to consider in a "redesigned" page. For example, how your new HTML code is structured; the order of content displayed to search engines (source code); how much of the original content you keep above the fold; relevance of your news to your current keyword(s); the number and quality of links added to this page; change in the amount of traffic to this page; and of course all the other technical and editorial SEO factors. Only thought about this for a few minutes but I'll post back if I think of anything else.

I'm a little confused about the redirect you want to implement. Are you unable to just replace the original page or use the original page URL? Note that permanent redirects tend not to pass 100% of your link juice http://moz.com/learn/seo/redirection. Try to do that, but if you can't then the redirect is likely your best option.
