If you’re thinking about partnering with a digital marketing agency to get you the results you need, you may have questions about cost, whether a third party could truly understand your business, and also why there has been a rise in in-house marketing teams.
There are lots of factors to consider when debating whether to partner with an agency or grow an internal team. With the digital landscape evolving quicker than ever and shoppers becoming more overwhelmed online, specific expertise from an agency should be welcomed so business leaders can focus on overall strategy.
Here are my top five reasons why businesses should engage with a digital agency in 2025.
1. Access to technical expertise
The top reason to consult with an agency is the amount of specialist knowledge they’ll bring to your business.
Areas such as SEO, PPC, social media, digital PR and content marketing require vastly different skill sets, and agencies have teams specialised in these areas. Agency experts also know how to make each channel perform well in a specific industry. It’s unlikely that business owners can bring all these skill sets and also have the time to focus on data and react to it quickly.
Instead, having a network of specialists at your fingertips looking at your campaign performance and making necessary adjustments to meet your business objectives will free you up to focus on overall strategy and staying ahead.
Plus, if you’re building campaigns using different channels, agencies can work together to allow the channels to work cohesively together.
2. Access to industry knowledge
Along with technical expertise, access to specific industry knowledge can significantly impact how quickly your marketing campaigns see success.
There are some agencies that specialise in certain industries, but those who are industry agnostic and work across various sectors will often have faced more scenarios and challenges to overcome. Agencies are likely to have wider experience across a variety of business goals from both an e-commerce and lead generation perspective.
With this experience, strategies will be built where potential roadblocks are anticipated but also successful methods from similar industries can be replicated and adapted accordingly. It’s fundamental for your agency partner to understand not just your business, but the landscape of your industry online to identify opportunities and stay ahead.
Plus, from an SEO perspective, understanding how Google positions you and your competitors online is the quickest way to replicate winning strategies for your industry as a whole, which will have more of an impact.
3. Cost-efficiency
Though agencies have their fees, hiring in-house specialists for each area, rather than having an agency of experts to consult, can equally be expensive and less efficient.
As agencies have established processes for your business to make the most out of the expertise, often with dedicated account managers that can handle the relationship, you’ll likely see quicker results and get more out of your overall spend.
Plus, agencies have tools and consistently upskill their team to stay ahead of trends in digital marketing to help sustain success for their clients. Upskilling an in-house team would take up time and continuous investment in training.
4. Creative ideas and reactivity
Along with close attention to detail on the analytics, there comes a big resource of creative minds to help shape your campaigns when you partner with an agency.
Without consistent upskilling and investment, in-house teams may get complacent or due to working within an echo chamber, run the risk of not testing alternative strategies or being exposed to fresh ideas like teams are every day within an agency.
Similar to the previous point about industry knowledge, channel experts within an agency often have different clients where various strategies can be tested and successes can be replicated or adapted to suit your business, whereas this exposure isn’t possible for in-house teams who can easily miss identifying these types of opportunities.
You might make the case that agencies won’t understand your brand as strongly as an in-house team might, but the right agency for you will take the time to understand your business and objectives and know how to make the campaigns perform accordingly.
5. Increased ROI
A summation of everything above, then, will likely lead to a stronger performance and increased ROI compared to an in-house team. It’s in the interests of marketing agencies to retain clients and scale the business by adding further channels to your strategy, so data-driven approaches are used to ensure success.
Campaign tracking tools are often used by agencies to keep track of performance, not only as a means of feeding back results to business owners but also to help make informed strategy decisions that are all aligned with increased ROI.
Summary
While there may be a trend in growing in-house marketing teams as a result of trying to cut back costs, engaging with a marketing agency that understands your business is a rewarding decision.
The businesses that continue to invest in showing up across their target audience’s buying journey consistently are sure to win.
Access to expertise, when digital marketing is evolving so quickly, is more important than ever, as well as the creative and forward-thinking approach you’d get from an agency. All of these reasons will help drive quicker results, and cost-effectiveness and allow you to focus on the overall strategy of where your business is heading long-term.
