[bikabon]

In MaxBounty, there is a traffic type called contextual. It goes contextual traffic is "pop overs/unders, in text ads".
What is "in text ads"?

And what is band bidding traffic?

contextual traffic is "pop overs/unders, in text ads".
What is "in text ads"?

I have a blog. If I sign up to a traffic provider as a publisher and agree to "in text ads", they will highlight certain words in my articles that are relevant keywords for the advertisers' offer.
So if the advertiser is selling fountain pens, for example, every word in my blog that's relevant to fountain pens will be hypelinked to their landing page.
In the case of pop unders/overs instead of a hyperlinked text, they will display a pop under/over instead.
