The SEO Debate
For years, companies have debated whether to build an in-house SEO team or outsource to an agency. While having an internal team may seem like a logical step, more businesses are realising that outsourcing to an SEO agency is the smarter, more cost-effective choice.
Let’s break down why companies are choosing to outsource their SEO rather than keep it in-house.
1. in-House vs. Seo Agency: SEO Requires a Team of Specialists
SEO isn’t a one-person job—it requires multiple skill sets, including: Technical SEO (site speed, indexing, mobile-friendliness).Content strategy (keyword research, blog writing, search intent). Link building (backlink acquisition, digital PR). Analytics & reporting (tracking performance, conversions)
Hiring an in-house team means recruiting multiple specialists, which can be costly. For example, you’ll need to learn about essential html tags and everything in between in order to manage them.
Agencies already have experienced professionals working together, offering a full-service approach.
2. Outsourcing is More Cost-Effective
Building an in-house SEO team means paying for: Salaries for multiple employees. Training and professional development. Premium SEO tools and software. Employee benefits and overhead costs
Agencies, on the other hand, offer expert SEO services for a fraction of the cost. Instead of paying multiple salaries, businesses pay a set monthly fee and get access to a full team of experts.
3. Agencies Have Access to Advanced SEO Tools
SEO success depends on data, but premium tools are expensive. Agencies invest in: Ahrefs & SEMrush (competitor research, keyword tracking). Google Analytics & Search Console (performance monitoring). Screaming Frog (technical audits). Surfer SEO & Clearscope (content optimisation).
These tools can cost thousands per year—an expense that’s already built into an agency’s services, saving businesses money.
4. Agencies Stay Ahead of Algorithm Updates
Google rolls out thousands of algorithm updates annually, and keeping up with them is a full-time job. Agencies: Monitor updates and adjust strategies accordingly.
They also prevent rankings from dropping due to algorithm changes by using data-driven strategies to stay ahead of competitors
An in-house team may struggle to adapt quickly, while agencies specialise in staying ahead of search engine trends.
5. Faster Results & Proven Strategies
SEO is a long-term game, but agencies have the expertise to get results faster. They: Identify quick wins for immediate ranking improvements.
They Implement tried-and-tested methods rather than experimenting by using data insights to refine strategies efficiently.
With an in-house team, businesses often go through a trial-and-error phase, whereas agencies already know what works.
6. In-House vs. SEO Agency: Scalability & Flexibility
SEO needs change over time. Some months require aggressive optimisation, while others focus on maintenance. Agencies offer the ability to scale up or down as needed.
They also have expertise in expanding to new markets (e.g., international SEO) and are flexible without the long-term commitment of hiring new employees
With an in-house team, scaling SEO efforts requires hiring and training more staff, which isn’t always practical.
Why Transparency Is So Important with an Agency
When you’re hiring an agency, there are so many different elements you have to look for. Of course, you want them to have experience and understand your industry.
But, you also have to pay attention to the team and what they’re like to work with. Namely, something important that you must search for is transparency.
This is going to be crucial to a successful relationship. Let’s take a look at why.
To Understand the Process
There are many business owners who are impatient because they don’t know the process the team uses. Thankfully, when you have transparency, you can see exactly what the team is working on and understand the timeline of when to expect results.
What’s more, you can make sure that the team are working in a way that you approve of. For example, if you were to hire an SEO agency, you can make sure that they’re not using black hat SEO techniques.
To See Results – In-House vs. SEO Agency
Let’s not forget the most important reason why you need transparency. You must ensure that the team are working towards your goals and achieving the results you’re looking for.
Therefore, you can see where your business started and what’s been achieved when the team provides you with regular updates and reports.
Gives You Peace of Mind
You want to feel confident that you can hand over responsibility to an agency. When you’re kept in the loop and can see the progress that the team is making, you’re going to enjoy peace of mind.
You can know that your money is being spent wisely and confidently work on other projects for your business.
Conclusion: In-House vs. SEO Agency
While having an in-house SEO team might seem appealing, the reality is that outsourcing to an agency offers better results, cost savings, and access to specialised expertise.
With agencies handling SEO, businesses can scale faster, adapt to search engine changes, and achieve sustainable online growth—without the burden of hiring, training, and managing an internal team.
If you want to maximise your SEO potential, outsourcing might just be the best decision for your business.
