Performance-driven online advertising

From the beginning, SEM has been Keyade's core business. Over time we have branched out to other mediums to continue to meet our clients' growing multi-channel needs. Our expertise:

Display / RTB
Social Media

Keyade covers 60 countries in 35 languages from its offices in Paris and Dubai, with an annual media budget of € 120M.

Proven methodology

Successful online advertising follows from tight synergy between the three primary players: advertisers, ad platforms, and media agency operators. We at Keyade are convinced that a deep understanding of each party's expectations allows us to create, analyze and optimize online ad campaigns efficiently and effectively.

Technology that powers human decisions

While having the right data is vital, the quality of campaign optimization rests on the men and women behind the analysis and decisions. We believe in using technology to help us make better decisions, not make decisions for us.

Close connections with ad platforms

We work in close collaboration with all the major ad platforms. This proximity ensures ongoing speedy exchange of information and access to beta testing of all new formats.

Madmetrics Analytics,
Keyade's proprietary technology

Originally developed in 2006 for Keyade's own operational needs, Madmetrics is first and foremost a cutting-edge technology suite that measures media campaign effectiveness and provides campaign optimization decision support.

Performance driven management
We collect and analyze data at the most granular level of the media tree because ROI-driven media management means meticulously optimizing the details to raise the average.

KPI-driven campaign management

Your key indicators are incorporated into Madmetrics Analytics to ensure your campaign is managed according to your own business model.

Save time, increase productivity

Powered by our talented team of developers based in Paris and a flexible organizational structure, Madmetrics Analytics follows a short development cycle which allows us to continuously and quickly adapt to our clients' operational needs.

Multiple data readings

There is always more than one way to read data. That's why we have developed a variety of custom attribution models (SEM brand deprioritization, cross-channel contributions, etc.) to ensure data analysis from every angle.

24-7 access

Transparency is at the heart of our partnerships. Each advertiser has continuous full access to Madmetrics Analytics and can see the results of our campaign optimizations in real time.

01/01/2015 – Keyade wishes you a prosperous 2015

New year, new priorities. In 2015, we want to take Keyade further. Further, with clients who put their trust in us. Further, with our growing team. Further, as part of the international conglomerate we joined some months ago.

Successfully integrating with WPP, the world leader in media and marketing communications, is an exciting challenge! To meet this challenge, we look forward to working together with our fellow WPP agencies while preserving the successful model we have built together with our account managers, starting in Paris 9 years ago—a model that relies on advanced technology, agility, continuous training, and experienced oversight. Our guiding principle remains to continuously learn from others in order to better understand our world's ever rapidly changing digital economy.

One of our primary focuses in 2015 is to more clearly define the value that a media agency does and should provide. Too often companies make the mistake of deciding to handle their media campaigns in-house without having made adequate preparations, due to a lack of understanding of the added value provided by media agencies and a misplaced assumption that in-house reduces costs. Nevertheless, a media agency that does its job well creates the ideal digital environment for each of its clients. It must be a laboratory of ideas, a forum for sharing experiences and skills, and a cutting edge reflection of the latest changes in the digital landscape which no in-house operation or machine algorithm can match. This goes hand in hand with a deeper understanding of operations and processes. We at Keyade are of the firm conviction that in a highly technical environment, the human, the tactical, and the analytical trump the mechanical. We intend to continue steadfast along this path. We will also continue to provide an environment where our existing talent can grow, and in turn attract new talent.

In 2015 we look forward to further advances in SEO, lever convergency, case studies, new formats, and more. There's so much to share and do together. Can't wait to get started!
