Wildposting®: Transforming London's Streets into a Marketing Playground

Wildposting® is the epitome of street marketing, a strategic endeavor that elevates the urban environment into an influential advertising platform. This sophisticated approach carefully situates posters and advertisements in high-traffic urban locales, ensuring their conspicuous presence among the daily passersby. What sets wildposting® apart is its innate creativity and unorthodox appeal, particularly resonating with discerning demographics, such as the younger generation, who demand authenticity and originality from the brands they engage with. By taking to the streets, your brand becomes an integral facet of the urban landscape, imparting a message that transcends mere visibility. In the realm of street marketing, wildposting® serves as a high-impact instrument, affording businesses the opportunity to establish authentic and enduring connections with their intended audience, leaving an indelible mark on the city’s vibrant streetscape.

With over 40 years of experience executing guerrilla marketing campaigns across North America, Grassroots Advertising has recently expanded our network across the globe. Our most popular marketing method is Wildposting®, which strategically places posters throughout the city for maximum exposure at an affordable cost. As the most visited city in the world, London offers unparalleled opportunities to reach an enormous and diverse audience. From its many tourist attractions, such as heritage sites and essential landmarks like Buckingham Palace, Trafalgar Square, the British Museum, and the National Gallery, to its longstanding and thriving art scene, London is the perfect market for music or arts campaigns. The city has a longstanding history of supporting DIY culture and is known for producing some of the most influential punk bands in history.


In addition to Wildposting®, we offer a range of other advertising mediums, including murals, ambient advertising, and experiential marketing. Experiential campaigns are perfect for events, as they stand out from the crowd and spread the key messaging of your brand in a more targeted manner. London has the second-largest immigrant population in the world, making it an incredibly diverse culture with more than 300 languages spoken. Whether you’re targeting the upscale neighborhoods of Chelsea or the counter-cultural areas of Camden Town, our team of experts can help you find the neighborhoods most suited to your campaign.
