Choosing the right digital marketing agency for you

When making an executive decision about which London-based digital marketing agency you want to work with, it's important to consider the following…

What makes a good agency and what is it I’m looking for?

  • Competitive, affordable pricing – this is hard to find online, but our cost comparison tool can help
  • Proven track record of results – be sure to check the agency’s website for real-life case studies that showcase positive results
  • Awards – with over 7,000 digital marketing agencies operating in the UK, a great way to identify the best of the bunch is through any prestigious and reputable awards they’ve won
  • Experience and specialism in a particular industry – think about the industry you operate in and find an agency that is focused on growing businesses in that industry. For example, Loud Mouth Media specialises in supporting the marketing goals of ecommerce businesses. They are our top recommendation if you operate in this sector
  • Services – check what services the agency offers. Does it cater to all of the channels you need? Is it well-versed in a particular solution that your business needs support with, such as SEO or paid social media? If it's SEO support you are after, agencies like Pearl Lemon are the best choice for your business
  • Reliable, transparent data and insights – an agency is only as good as its reporting. Make sure you have constant access to insights and reports so you know how the agency is performing and can monitor the success of any marketing campaigns
  • Collaboration and communication – the most highly regarded and successful agencies have open and honest working relationships with their clients

As well as the above points, also consider asking the following questions during your initial consultation with any agencies:

“Can I see some previous campaign examples?”
(This will indicate what the agency is able to produce).

“Will you provide a dedicated account manager?”
(Knowing you will have someone handling your account will ensure you have constant contact and support from the agency).

“How long do clients typically stay with you?”
(A marketing agency that has long-term loyal clients shows it’s doing something right).

“How are you competitively priced compared to other agencies in London?”
