Lately wordpress have been giving me some trouble. I run 2 directory websites which I am constantly adding new content to each day, getting clients and ect. Both websites I started January 2013. The theme I am running is WP Local places which in my opinion is not very good. I want to change my site to Vantage theme: better support, looks more professional and easier to manage. Now my problem: Say I have a business listing and a.t.m the permalink looks like this: websitename.domain/place/business-name-area. With Vantage theme each listing page has this type of permalink structure: websitename.domain/listing/business-name-area. Besides having over 300 listings for each website I am really scared to change permalinks because all my website pages are already indexed and posted to all my social accounts (I use next scripts social poster). I also don't want to spend days updating everything as I need to focus on getting clients. What is my best option in terms of SEO, getting my pages indexed quickly, and simply not leaving my site in a state of chaos? Any help would be hugely appreciated!!!
