Bid jamming - A lactic used in competitive bidding for keywords for paid placement
on search engines, bid jamming keeps a bid marginally below that of a chosen competitor, so requiring them to pay the highest possible cost-per-click (CPC) value to maintain a particular position. In other words, you do not win the highest placement, but you do force up competitor's costs. Manual practice of such a tactic is virtually impossible, utilization of bid-management software being the norm. Bid jamming might be considered to be the converse to bid shadowing.
