Hello.
I am selling guest posts on my personal technology blog.
It's runing on wordpress.com ( its a web 2.0 blog ). Traffic is around 2000 / month all organic. If you want to see the url, ask for it and i will send you a PM.
Guest post can be written by me ( i write articles daily, can easily include a contextual link in it ) or you can provide it as long as its an unique one.
Placement is permanent. This is not part of a network or something, its a personal blog with real people visiting it.
Page Authority is 31.Quality is high, and as white hat as it can be.
I am around most of the day if you have any questions and I will gladly reply.
Have a great day!
