Still i am using different content for Article submission and Classified submission separately.Can i use the same content for both Article and Classified submission?If same content use means it will consider as spam or not?
No, you can not use the same content for article and classified because search engine are not allowed to do copy content.
Do proper on-page then do create 100 links a day and with content spin
You can't use the same content both Article and Classified.
I think you can use some amount of your content in ad post, i am also do it with some modification.
And one more thing is ad post is remain for limited period.
No, it would be considered as a duplicate content.
