The outdoor and press activity breaks today (19 October) and will run for one month.
The campaign uses the strapline “Gone Google” and is being run by the search engine’s Google Enterprise division.
It is promoting services such as Google Mail, Google Docs, Google Earth and Google Maps as well as its digital security services.
The “Gone Google” line refers to the businesses that are already using the firm’s services.
The ads aim to highlight the reliability and quality of Google’s products and use lines such as “Day 9: Email inbox is full. Grrr!!! Go Google?”
The campaign is Google’s first major above-the-line UK push. The search engine has previously run smaller campaigns in trade magazines and websites and joint initiatives such as the 2006 campaign with British Airways that showcased Google Earth.
