What Is a Full-Service Marketing Agency?

A full-service marketing agency typically offers a comprehensive range of marketing services, ensuring that all of your marketing needs are met by one external source. 

Many marketing agencies focus on specializing in a particular aspect of marketing, such as SEO or PPC, but a full-service agency acts as an all-in-one solution, saving valuable time, costs, and effort.

What Types of Marketing Does a Full-Service Agency Include?

Let’s dive a little deeper into what ‘full-service’ actually covers, broken down by some of the most common marketing terms like digital, creative, traditional, and data.

Digital

Digital marketing has become an increasingly integral part of business growth thanks to rapid advancements in technology. 

Due to this increase, digital marketing has gone from being a generic term for all things digital to an umbrella term that covers four main categories: SEO, PPC, social media, and email.

• SEO (search engine optimization) has risen in popularity in recent years with its specialized focus on driving organic traffic to company websites.
• PPC (pay-per-click) is also popular and involves buying media or ad placements that appear at the top of search results (or on social platforms) with the aim of generating traffic.
• Social media marketing has become increasingly important as brands turn to social media for brand exposure, authority, and engagement with their community.
• Email marketing involves curating lists of leads and existing customers, categorizing or segmenting audiences, and then building engaging email communications. 

A high-quality full-service agency typically covers all of these aspects in great detail.

However, many agencies may choose to specialize in one area of marketing in particular. So, it’s best practice to carefully review what your marketing agency offers.

Creative

Creative marketing is incredibly important and involves design aspects such as branding, digital design, and video creation.

For companies keen on adopting an omnichannel approach to marketing, having visual components is crucial. Not only does it ensure they can make their brand look professional, but it also allows them to create much more engaging content for socials and websites.

Traditional

While the world of digital marketing has certainly grown in recent years, traditional marketing avenues are still highly valuable. 

Options such as print, TV, and radio, can be extremely effective and they may be important considerations depending on your brand’s target audience.

Data and analytics

High-quality data and analytics teams can track performance and identify areas of success as well as areas that need to be fine-tuned to ensure your budget is as efficient as possible.

They may review key metrics like ROI (return on investment) and engagement (open rates, click rates, organic traffic, paid traffic, and purchase data) across multiple marketing channels.

Other services

There are also additional marketing aspects that a full-service marketing agency may provide. However, they may not be on offer at every agency. 

One of those is PR, as PR can play a significant role in digital marketing efforts. 

By publishing stories about your brand or reaching out to local journalists, your brand can quickly become established as a thought leader whilst also building backlinks to your website for SEO purposes.

Then, influencer marketing is another aspect that is on the rise. Micro and macro influencers can leverage their relationship with their audience to promote brand awareness.

The Benefits of Using a Full-Service Marketing Agency

There are extensive benefits that come from finding an effective full-service marketing agency. 

• For starters, it tends to be a more cost-effective approach than working with multiple companies and freelancers.
• It’s also easier to integrate a single marketing agency into your overall business than multiple agencies. 
• The more closely a full-service marketing agency is integrated, the better they’ll understand your brand.

Lastly, working with a single full-service marketing agency ensures you have one point of contact for any issues and concerns, helping you to keep track of all your projects.

Final Thoughts: Selecting The Best Full-Service Marketing Agency

Keep in mind that not every full-service marketing agency is built the same. Some may specialize more strongly in certain aspects of marketing or have a different range of marketing services they provide.

To ensure you find the right fit for your needs, look at marketing agencies that have a proven track record and portfolio, with transparent customer case studies, allowing you to truly assess the quality and results of their work.

Finally, spend time reviewing their reporting practices and understanding how they measure campaign success. 

You want an agency that offers regular, clear insights, as well as actionable recommendations for how you can gain even more success.
