Thank you!
I'm previously using all in one pack and now wordpress seo by yoast.

 

How about "The best adsense management plugin ?

 

wordpress seo by yoast is good
All in one pack is not bad either

 

I don't use an plugin to manage ads.
I use Google DFP to manage all my ads and place them directly in my theme.

 

All in one SEO.

 

I think you're using the Pro version ?
Free version is limited and lack some good features.

 

Nope, free. www.mw3blog.com recently reached 100,000 unique visitors.

 

Does this work with xenscripts' bridge ?

 

yes

 

using it already for 4 days in my new blog but then, google doesn't index any of my post

 

It takes time.

I do suggest you add it to google's Webmaster Tools.

 

Yes I already add all the sitemaps the day I installed it, but then all my blogs still not index.
My wordpress is install under mysite.com/blog
What would you advice running wordress, inside a sub directory or in the root it self.

 

I wouldn't recommend putting it on sub-directory if root isn't being used.
