Through behavioral and contextual targeting technology, Clicksector.com provides online advertising auction service. The advertisers can bid for placement ranking under cost per visit CPV, cost per click CPC and cost per 1000 impression CPM. I have tried to use both advertisers and publishers service. In advertiser side, they provide geographic targeting, keyword targeting, channel targeting, site block, pixel tracking to advertisers to optimize the campaign and improve the conversion. However, it is not pretty good for the site block function. You cannot see the exact URL. You can only see the id. So if you notice this site id has spent more money with no conversion, you can block this website. For the publisher side, you can use their text banner, inline text link, graphical banner or pop under. The CPC and CPM are not pretty high but acceptable.
