The majority of founders and marketing officials do not know – or knowingly ignore it. It is now possible to consult, in a few clicks, all advertisements disseminated by their competitors on the main advertising platforms. No paying tool, no hack, no insider: only public advertising libraries, maintained by Google, Meta and Linkedin.
A reflex still too rare
Asking a founder about the advertising positioning of his competitors often reveals an admission of helplessness: “We do not really know what they say”, “we imagine that they target the same personas”. However, just a few minutes to check it. Meta (Facebook, Instagram), Google (YouTube, Search, Display) and Linkedin platforms make accessible to all sponsored contents disseminated by companies – past and in progress. These libraries make it possible to go up the history of the campaigns, to analyze the messages tested, the formats used and the time of distribution. In short, an x-ray of opposing Go-to-Market efforts.
