Online Advertising London: Find the Best Fit for Your Brand

Finding the best online advertising agency for your business can be very challenging in London. There are hundreds of digital advertising companies who seem to have it all. However, not all of them are the right fit for your brand, and that's why you must be careful.

We understand that choosing the best digital marketing agency for your company - among the leading advertising agencies in London - will require more of your time, energy, and even money.

So, we are compelled to share three (3) useful tips or reminders to help you quickly and easily find the right online advertising partners that fit your brand's marketing needs, demands, and standards.

Take advantage of a digital marketplace for online advertising companies in London

Using a B2B marketplace for online advertising agencies in London, and around the world, can immensely help you in finding the best digital marketing agency for your business without having to spend too much time and effort in your search - you can even hire the right fit within minutes instead of days!

Plus, even though your search may only take a few minutes, you can rest assured that the platform has already painstakingly listed the digital marketing companies that are highly recommended for your brand.

Sortlist follows high-value criteria to make sure that we only show the advertising services and agencies based on the standards needed by our clients.

We base our criteria around the core needs and demands of our clients, such as the following in no particular order:

  • The location of the digital marketing agency
  • The expertise of the agency and the services that they offer
  • The languages that the marketing team speak and use in their services
  • Your marketing budget as a brand
  • Your preferred agency size in terms of the number of employees
  • Your business niche or industry
  • Your specific plans and goals for your online marketing campaigns


With these criteria and the intuitive digital platform that Sortlist has as a marketplace, your stressful and long days of finding the best marketing team for your brand are over! Feel free to experience the smooth process in our website today.

Choose the digital marketing company that has experience marketing similar businesses in your industry. 

Making sure that the digital media company you choose has experience with similar businesses in your industry can prove invaluable. Through this, your online marketing support already has a profound understanding of your pain points as a business.

Also, their experience will play a massive role in making your digital strategy even better regardless of how "boring" your business niche might appear in popular social media sites or any other social platforms that your target audience typically hangs out.

Moreover, the more experience that your chosen digital marketing experts have on your industry, the better the media content they can produce for your website and social media accounts, and the better they capture your target audience's attention and pique their interest with compelling and informative content.

Remember these three (3) vital factors to consider before you sign a contract with your new advertising agency

Before you hire your new online advertising agency, remember to bring up these three essential factors to make sure that the agency is, indeed, the best fit for your brand.

The factors are:

  1. The management of their own marketing or media agency
  2. The KPIs that they track
  3. The results they promise


These factors can be assessed by asking a few crucial questions, such as:

  • How do they manage their own agency? Check the results they have acquired for themselves.
  • What KPIs do they consider important? Make sure they mirror the KPIs that you have for your brand, especially in website optimisation, social media and digital marketing.
  • What results do they promise for your company? Be careful with those who guarantee the "bottom of the funnel" almost too confidently.
