Do SEO yourself or use an agency? What’s best for your business?

Many business owners face the same dilemma: should you spend time and effort learning search engine optimisation on your own, or is it smarter to hand the job over to an agency with specialist expertise? The answer is rarely black and white. It depends on the size of your business, your ambitions, your internal resources, and how far you’ve already come in the digital sphere. A small online shop with three employees has completely different circumstances to a medium-sized consultancy firm with 50 employees and a dedicated marketing team. This article gives you an honest picture of what both options actually entail, so that you can make an informed decision that suits your specific situation. Because there is no one-size-fits-all solution here, just trade-offs you should be aware of before choosing a direction.

What does SEO involve in practice?

Search engine optimisation may sound simple on paper: make sure Google finds and likes your website. But in reality, it is a complex field spanning technical development, content strategy and reputation building. The three pillars at the heart of all SEO work are technical optimisation, content production and link building. Each of these requires different skills, different tools and different timeframes. Let’s take a closer look at what they actually entail.

Technical SEO and website performance

Technical SEO is all about what happens ‘under the bonnet’ of your website. This includes load times, mobile responsiveness, correct use of HTML tags, structured data, crawlability and indexing. Google rewards websites that are fast, accessible and technically sound. If you have a website built on WordPress with a heavy theme and ten outdated plugins, you’ll struggle to rank no matter how good your content is.

A common problem among Norwegian businesses is that the website was built five or six years ago without any thought for technical SEO. In such cases, a thorough technical review – often called an SEO audit – may be necessary to identify what needs fixing. Such reviews require tools such as Screaming Frog, Google Search Console and PageSpeed Insights, and, not least, the expertise to interpret the data correctly.

Content production and keyword analysis

Content is the fuel of any SEO strategy. Without relevant, well-written content, you have little to rank with. Keyword analysis is the starting point: you need to understand what potential customers are actually searching for, and how they phrase their queries. Tools such as Ahrefs, SEMrush and Google Keyword Planner provide you with data on search volume, competition and related terms.

Content production itself is about more than just writing blog posts. It includes landing pages, product descriptions, FAQ pages and pillar pages that cover broad topics in depth. A good content strategy maps out the entire customer journey, from the initial search to the purchase decision, and ensures your business is visible at every stage. And here’s an important caveat: AI tools can provide you with a draft that is perhaps 80 per cent complete, but it always requires human quality control and adaptation to strike the right tone and actually provide value to the reader.

Authority and link building

The third pillar is authority, which is largely built through links from other websites. When reputable websites link to your content, Google interprets this as a vote of confidence. Link building is perhaps the most time-consuming and difficult part of SEO. It requires relationship building, PR work, guest posts and the production of content that others actually want to reference.

For Norwegian businesses, there are often limited relevant link sources compared to English-speaking markets. This makes link building a strategic exercise where quality trumps quantity. A single link from a respected Norwegian industry portal can be worth more than twenty links from irrelevant blogs.

Advantages and disadvantages of doing SEO yourself

Many companies start by doing SEO in-house, either because their budget is limited or because they want full control over their own digital presence. It is entirely possible to achieve good results on your own, but it requires a realistic understanding of what you’re getting into.

Cost savings and full control

The most obvious advantage of handling SEO yourself is that you avoid paying for external services. You invest time rather than money, and for an entrepreneur or a small team, this can be a sensible priority during the start-up phase. You also gain full control over the strategy, can react quickly to changes and build in-house expertise that becomes a lasting asset for the business.

There are plenty of free and affordable resources for learning SEO. Google itself offers courses through Google Digital Garage, and YouTube is full of quality content from recognised SEO experts. With discipline and a systematic approach, you can go a long way. Particularly for local businesses looking to rank in their local area, basic SEO measures can have a noticeable impact without external help.

Time-consuming and steep learning curve

Here comes the reality check. SEO isn’t something you can learn in a weekend. Algorithm changes, technical challenges, content strategy and link building each require hundreds of hours of learning and practice. Many business leaders underestimate how much time it actually takes to do SEO properly, and end up with half-hearted measures that yield minimal results.

A typical scenario: you spend two evenings a week writing blog posts and tweaking meta tags, but after six months you see hardly any change in traffic. The problem is rarely a lack of effort, but a lack of a comprehensive strategy and in-depth expertise. SEO is iterative by nature, much like an AI project: you can’t just set it up and move on. It requires continuous fine-tuning based on data and results.

The biggest risk of doing everything yourself is the opportunity cost. The hours you spend learning technical SEO are hours you aren’t spending on your core business. For a business leader who charges 1,500 kroner an hour, ten hours of SEO work a week can quickly become an expensive affair, even if it doesn’t appear on any invoice.

When should a business consider an SEO agency?

There are some clear signs that it is time to consider external help. Perhaps you have tried doing SEO yourself without seeing any results. Perhaps the business is growing faster than the in-house team can handle. Or perhaps you have simply realised that search engine optimisation requires a type of expertise you do not have in-house.

Access to specialist expertise and tools

A dedicated SEO agency works on search engine optimisation every single day. They have specialists in technical SEO, content, analytics and link building. The difference between a generalist and a specialist can be compared to the difference between a GP and a specialist at a hospital: both have medical training, but the specialist has in-depth knowledge that makes a real difference in complex cases.

Professional tools such as Ahrefs, SEMrush, Surfer SEO and Screaming Frog cost several thousand kroner a month in total. An agency already has these tools and knows how to use them effectively. They also have access to historical data and benchmarks from other projects, which gives them a head start in their strategic work.

At Mediabooster, which has delivered over 450 web and marketing solutions across the Nordics, we often see companies coming to us after spending one to two years trying to do it themselves. Not because they lack motivation, but because they realise that specialist expertise delivers results faster.

Scalability and faster results

When you work with an agency, you can scale your efforts up or down as needed. Are you launching a new product? Then the agency can ramp up content production. Are there quieter periods? Then the focus can be on technical maintenance and link building. This flexibility is difficult to achieve with internal resources alone.

Results also typically come faster with professional help. An agency knows which measures yield the greatest impact and can prioritise accordingly. Whereas you might spend three months realising that your meta titles are too long, the agency has already fixed it and moved on to the next step. Experience-based prioritisation is one of the greatest values an agency brings.

That doesn’t mean SEO becomes a ‘quick fix’ with an agency. Organic visibility takes time regardless, typically three to twelve months before you see significant results. But with the right strategy from the start, you avoid the most common mistakes that delay the process.

The cost of outsourcing

Let’s be honest: an SEO agency is an investment. For many small businesses, it can feel like a significant budget item, especially when results don’t come overnight. It’s important to have realistic expectations and a clear agreement on what is to be delivered.

A common pitfall is choosing the cheapest option. Unfortunately, the SEO industry has its share of unscrupulous operators who promise the top spot on Google within a month. Such promises are red flags. Reputable agencies are transparent about what is realistic, and they report regularly on specific KPIs such as organic traffic, rankings and conversions.

Always ask about their track record. Request references from comparable businesses. And ensure the agency explains their strategy in a way you understand. If you don’t understand what they’re doing or why, it’s difficult to assess whether the investment is delivering a return.

How to calculate profitability for your business

Whether you do SEO yourself or use an agency, you should be able to calculate whether the effort is actually paying off. Many businesses operate in the dark here, and this is one of the most common reasons why SEO projects fail or are terminated prematurely.

ROI: Investment vs. organic growth

To calculate the ROI of SEO, you need a few key figures. Start by mapping out how much organic traffic you currently receive, and what that traffic is worth in terms of leads or sales. Then measure the growth over time and compare it with the investment you have made, whether in your own time or in agency fees.

A practical example: let’s say your business receives 500 organic visits a month, and the conversion rate is 2 per cent. That gives you 10 leads per month. If the average customer value is 15,000 kroner, organic traffic potentially generates 150,000 kroner a month. If you increase traffic by 50 per cent through targeted SEO work, we’re talking about an extra 75,000 kroner in potential revenue per month. Set this against the investment, and you have a concrete figure to work with.

Define measurable KPIs from the outset. These could include the number of organic visits, ranking positions for priority keywords, the number of leads from organic traffic, or organic revenue. Without clear goals, it is impossible to assess whether the strategy is working.

The opportunity cost of lost visibility

Here is a perspective many overlook: what does it cost not to be visible? Every day your business fails to rank for relevant keywords, potential customers go to your competitors. According to research, around 75 per cent of users never click beyond the first page of Google. If you’re on page two, you’re effectively invisible.

Think of it this way: your competitor who invests in SEO is building an ever-stronger lead. The longer you wait, the harder and more expensive it becomes to catch up. Organic visibility is cumulative: the content and authority you build today will pay dividends for months and years to come. It is one of the few marketing channels where your efforts accumulate over time, unlike paid advertising where traffic stops the moment you stop paying.

The hybrid solution: The happy medium?

For many businesses, the answer is neither to do everything yourself nor to outsource everything. A hybrid model where you handle parts of the SEO work in-house and let an agency take care of the rest can offer the best of both worlds.

A typical division of labour looks like this: the agency takes responsibility for technical SEO, strategy and link building, whilst you produce content in-house. No one knows your industry, your customers and your products better than you do. That knowledge is worth its weight in gold when it comes to content production. At the same time, you avoid having to spend time on the most technical and specialised aspects of SEO.

At Mediabooster, we often work as an extension of the client’s own team, not as a distant supplier who sends reports once a month. This model works particularly well for medium-sized businesses that have some internal capacity but lack specialist expertise in certain areas. We see it a bit like change management: it’s not just about implementing a strategy, but about building understanding and expertise internally so that the whole organisation is pulling in the same direction.

A hybrid solution requires good communication and clear lines of responsibility. Clarify who does what, how you report to each other, and which tools you use. Without structure, a hybrid model can quickly become chaotic, with duplication of effort and unclear priorities.

Checklist for choosing the right strategy

Before you decide, it can help to ask yourself some specific questions. Here is a checklist to guide your decision:

• Do you or anyone on the team have real expertise in SEO, or are you starting from scratch?
• How many hours a week can you realistically dedicate to SEO without it affecting your core business?
• Does your company have access to the necessary tools for keyword analysis, technical analysis and competitor monitoring?
• How competitive is your industry online? Local services often face less competition than national e-commerce players.
• What is your timeframe? Do you need results within six months, or can you build a long-term strategy over one to two years?
• Do you have the capacity to produce quality content regularly, at least two to four times a month?
• Can you measure and analyse results, or do you lack expertise in web analytics?

If you answered ‘no’ to three or more of these points, it is probably wise to involve an agency, at least to develop the strategy and set up the technical framework. If you answered ‘yes’ to most of them, you have a good starting point to go it alone, but still consider a professional review to ensure you’re on the right track.

Another useful exercise is to look at what your competitors are doing. If your three main competitors all use an agency and rank well, this is a sign that the market demands a professional approach. Trying to compete with them using sporadic blog posts and basic on-page SEO is like turning up to a car race on a bicycle.

Whichever path you choose, the most important thing is that you actually get started. Perfect is the enemy of good enough, and an imperfect SEO strategy implemented consistently beats a perfect plan that never leaves the drawing board.

The choice between doing SEO yourself or using an agency ultimately comes down to being honest with yourself about what your business needs and what you’re capable of. Both paths can lead to good results, but only if you go in with your eyes open and realistic expectations. What doesn’t work is doing it yourself halfway, getting frustrated by a lack of results, and then blaming it on ‘SEO not working for our industry.’ If you want a sparring partner who can help you find the right approach for your specific business, Mediabooster could be that partner.
