Minute Steak will provide paid search management, including campaign set-up, optimisation and reporting, to businesses who can't afford or don't require a comprehensive agency service.
Clients can choose their own packages, with no minimum spend or long-term contracts.
Piri Ramazanoglu, Minute Steak managing director, said: "For some time we have been approached by clients who want to manage their search marketing in a professional manner but for whom the full-service agency model is a step too far.
"With millions of small to medium-sized businesses and specialist companies in the UK, we know there is a demand for this type of service. We're looking forward to addressing that need and showcasing the benefits of successful search marketing to a new audience."
Justine Wyness, head of marketing and sales at lingerie and swimwear retailer , said: "As an online brand we know that search marketing will play a key part in our success, but we found our requirements couldn't be met by the big agencies that are set up to service big budget, big brand business.
"We're young, but growing fast, and Minute Steak offers us the right amount of help we need."
