I would like to know if it is possible to not get penalised by google for changing the subject of a category entirely. I would like to swap a category that I have built on a webpage, for one with a more relevant (as of now) topic. Changing description, content and title etc… would this destroy my SEO? It has amassed backlinks of great quantity and quality over the course of time and I seriously would not like to have them wasted or passed with internal links as the page itself is invaluable.
Assume anchors to my webpage were all "" for convenience purposes. They are nothing particularly descriptive.
Any input would be appreciated
