The description should be relevant to the category, there is no such need to change the description if you are submitting it to same category but if other then you have to change the description
Hy, I own a directory. I want to say that I allow only original description. This is the main criteria when accepting a site. So try to be unique. And my directory is FREE!
( I think unique description should be use everytime ) ( As I know about it description should always be same.) No I change the description for one of my directories and targeted some of 5 keywords. The title not changed Unique description was changed in each keyword.I submit paid links in good websites. It works
