I have a blog, http://www.cricketdiaries.com.
I want to change the theme of my blog. I also want to change my menu items - currently, it is news, previews and highlights etc and I want to change it to something totally different (something like IPL, ODIs, Tests etc).
The menus that I have currently (i.e. news, previews and highlights etc) are actually categories. My question is:
1. Can I directly delete the current menus from being seen without affecting google searches in any way? Will deleting the current menus make any difference to the posts that that were already put up?
2. I also need to delete a couple of pages that I have added (if you see on the site, there is a page called Champions League T20). Can I directly delete the page ; will the search engines have no issues with this?
It would be great if someone could guide me in this because I am relatively naive when it comes to the technical-related issues.
