What is a growth marketing agency?

Let’s get the elephant out of the room – what’s the difference between a “normal” marketing agency and a growth marketing agency?

Good question – here’s our perspective on the 3 main differentiators of a good growth marketing agency:

  1. Whilst normal agencies may specialise in search engine optimisation, paid advertising or brand positioning and creative, growth agencies are entirely centred around growth.
  2. Growth agencies tend to have a wide range of expertise across a range of different acquisition channels – such as email, SEO, paid ads, PR, referral marketing and more – as well as a framework or methodology for identifying good acquisition channels for your business, such as the bullseye framework. You may hear growth agencies call themselves “full-stack” since they fuse multiple aspects of marketing together.
  3. A growth marketing agency has a bias for both speed and data. Growth marketing agencies move fast, test ideas through agile experiments, and make data-informed decisions from the results.

How did we compile this list?

Having spent the last 10 years in growth we know a good growth marketing agency when we see one, and have an innate ability to separate fact from fluff.

We analysed all of the top results from Google, and used our own knowledge of industry experts, to create one of the most comprehensive lists of growth marketing agencies on the web.

How to choose a good growth marketing agency?

First of all, use the lists below where we have highlighted our recommendations for growth marketing agencies in the UK, Europe and the US.

Additionally, we provide growth marketing software to agencies (and in-house teams), hence do not compete with agencies directly, so on the off-chance you have found an agency that is not in our list, we’re always happy to vet them on your behalf – and to let you know our thoughts before you agree to work with them.

Failing that, our advice would be to:

  1. Ask for case studies of similar companies they have worked with
  2. Ask for references that you can speak with
  3. Take advantage of any free consultations on offer
  4. Start with a small engagement to determine your fit
