Adthena

Adthena from the company of the same name in London is a marketing intelligence tool for search marketing focusing on keyword research, analysis, and suggestion for optimizing the budgeting and management of pay per click (PPC) advertising campaigns. Adthena algorithmically searches industry-relevant keywords and also the actual ad copy appearing in search engines, a less seen feature used for competitive analysis and brand differentiation (i.e. so your ads appear or do not appear like your competitor's, as you prefer).
