I should probably do a post for it at some stage but here are a few things you could do
- use SFTP not FTP
- its a good idea NOT to use the default database prefix wp_
- use a complex password – lastpass is awesome for this
add these in to your .htaccess , so you don’t advertise your server details
these plugins might also help
If you want to rel publisher markup to be picked up by Google follow this : https://support.google.com/webmasters/answer/1708844?hl=en .
Knowledge Graph entries are not something that will pop up for all queries, it will show up for branded search , once Google makes the association for your brand for the search term. They source that information from brand pages on Wikipedia, FreeBase, etc so most likely you will need to have an entry on those sites too. In my experience this doesn’t show up until your brand page ( on Google+ ) builds up a certain level of engagement.

You can test if you have added the rel publisher tag correctly from here : http://www.google.com/webmasters/tools/richsnippets
hope that helps
