Link building is harder than web traffic building.
While link building is designed for web traffic building.
For link development, people just focus on back links to their homepages while web traffic development needs links back to each pages.
Only indexed pages in major search engines maybe not enough for web traffic.
Now you will see many link manager will change their behavior in exchange links by deep link exchange instead of homepage link exchange.
By the way, banner exchange will be less interested for link reciprocal development. They emphasize on text link exchanges with the wanted keywaords and keyphrases.
