Do you need an SEO agency in the age of AI? This is what matters

Google has changed more in the last two years than it did in the previous decade. Generative AI has turned the way search results are presented, how content is produced, and what is actually required to gain visibility, completely on its head. The question many Norwegian businesses are now asking themselves is, naturally enough: do we really need an SEO agency when AI tools can do so much of the work? The answer is not a simple yes or no. It depends on your level of ambition, in-house expertise, industry, and how much is actually at stake.

How AI has changed the rules of the game for search engine optimisation

Search engine optimisation has always been in flux. Algorithm updates, new ranking factors and changing user expectations have forced companies to adapt constantly. But over the last couple of years, the pace has accelerated dramatically. AI has not just become a tool in SEO work: it has changed the very foundation of how Google understands and presents information.

From keywords to intent: Understanding SGE

Google’s Search Generative Experience (SGE) represents a fundamental shift. Instead of displaying ten blue links, Google now generates AI-powered answers directly in the search results. For the user, this means faster answers. For businesses, it means that traffic to your website may drop even if you rank highly, because Google has already provided the answer.

The traditional focus on keywords is no longer enough. Google has moved from matching keywords to understanding intent. If someone searches for ‘best project management tools for small businesses’, Google expects the content to actually compare tools, provide specific recommendations and demonstrate that the author has real-world experience. Superficial content that merely repeats the keyword in different variations is filtered out.

For Norwegian businesses, this has a concrete consequence. It is not enough to publish a blog post with the right keywords and hope for the best. You need to understand what the user is actually trying to achieve, and deliver content that actually solves the problem. SGE rewards depth, originality and credibility. Content that merely summarises what everyone else has written stands little chance against AI-generated summaries that do exactly the same thing, only faster.

The rise of automation in content production

ChatGPT, Claude, Gemini and a host of other AI tools have made it possible to produce content at a pace that was unthinkable just three years ago. A marketing manager can now generate a draft blog post in ten minutes. Technically, anyone can produce SEO content.

But here lies the trap. AI-generated content is typically 80 per cent complete. It gives you a solid start and saves a lot of time, but it requires human quality control and adaptation to be truly effective. Without editing, fact-checking and adaptation to your brand, you end up with generic text that resembles everything else Google has already indexed. And Google has become increasingly adept at identifying and downgrading content with no genuine value.

Automation has also created a paradox. When everyone can produce content quickly, the volume increases enormously, but the average quality drops. This means that businesses investing in quality actually have a greater opportunity to stand out than before. The question is simply whether you have the in-house expertise to apply that final, crucial polish.

The value of an SEO agency when the technology is available to everyone

Many people think that access to AI tools makes SEO agencies redundant. The logic seems simple: if the tools are available to everyone, why pay someone else to use them? But this way of thinking overlooks something essential. Tools and strategy are two completely different things. A saw does not make you a carpenter.

Strategic advice vs. tool management

An SEO agency that merely runs tools and delivers reports offers you little more than what you could achieve yourself with a Semrush licence and some training. What distinguishes a good agency from a mediocre one is the ability to interpret data and translate it into business decisions.

Think of it this way: AI can tell you that a keyword has 3,000 monthly searches and medium competition. But it takes human judgement to determine whether this keyword actually leads to conversions for your specific business. Perhaps the keyword attracts people who are merely curious, not those ready to buy. An experienced agency like Mediabooster, with over 450 web and marketing solutions delivered across the Nordics, has seen enough data across industries to recognise such patterns.

Strategic advice is also about prioritisation. Most businesses have limited resources. Should you focus on technical SEO, content production or link building? The answer varies enormously depending on your starting point, and the wrong priorities can cost you months of lost visibility.

E-E-A-T: Why human expertise matters more than ever

Google has tightened its requirements for Experience, Expertise, Authoritativeness and Trustworthiness (E-E-A-T). This is no coincidence. When AI can generate text on any subject, Google needs other signals to assess quality.

For a business in the healthcare sector, this means your content must demonstrate that it has been written or quality-assured by someone with relevant expertise. For a law firm, this means that articles should reflect actual legal experience. For an online shop, this means that product reviews must appear genuine and based on real experience.

An SEO agency with expertise in E-E-A-T can help you structure your content so that these signals are clearly evident. It covers everything from author biographies and source references to internal link structure and how you present your expertise. AI tools cannot assess whether your content actually meets the E-E-A-T requirements in a credible way. That requires human judgement.

Managing technical SEO in a complex landscape

Technical SEO has become more demanding, not simpler. Core Web Vitals, JavaScript rendering, crawl budget, structured data, hreflang for multilingual pages, and now adaptation to SGE: the list is growing. AI tools can identify technical errors, but fixing them often requires cross-disciplinary expertise in development, UX and SEO simultaneously.

A common scenario: a Norwegian online shop discovers via a crawl tool that 40 per cent of its product pages are not being indexed. AI can highlight the problem, but the solution may involve changes to server-side rendering, cleaning up canonical tags, and restructuring internal linking. This is work that requires experience with similar projects, not just access to the right tools.

Many companies also underestimate the importance of technical SEO compared to content. But without a solid technical foundation, it doesn’t matter how good your content is. Google simply cannot find or understand it.

When should you do the work yourself using AI tools?

There are certainly situations where it makes sense to handle SEO in-house, particularly with AI tools to support you. Not every business needs an agency, and it’s important to be honest about that.

Cost-benefit analysis for small and medium-sized businesses

For a small business with a limited marketing budget, an SEO agency can seem like a major investment. And sometimes it’s smarter to start with what you can do yourself. If you have an employee with an interest in digital marketing and a willingness to learn, AI tools can provide a good starting point.

Here are some situations where an in-house approach can work:

• You operate in a niche with low competition and need basic visibility
• You have a technical platform that is already well set up (for example, a standard Shopify shop)
• You have the capacity to spend 5–10 hours a week on content creation and optimisation
• You are willing to invest time in learning basic SEO principles

But be realistic. If you’re competing in a market with strong players, or if organic traffic is a significant part of your business model, the risk of making mistakes is considerable. Six months of lost visibility could mean lost revenue far exceeding the cost of an agency.

The risks of blindly relying on AI-generated content

AI tools have a well-known weakness: hallucinations. They can generate content that sounds convincing but contains factual errors, outdated information or outright misinformation. For a business that publishes such content without quality control, the consequences can be serious. It is not just about SEO rankings, but about reputation and trust.

Google has also made it clearer that they do not penalise AI-generated content in itself, but that they penalise low-quality content regardless of how it is produced. The difference between AI content that ranks and AI content that is ignored is almost always human editing.

A concrete example: a Norwegian financial advisory firm used ChatGPT to generate articles on pension savings. The content was grammatically correct and seemingly informative, but contained several outdated references to tax rules. The result was not only poor rankings, but also complaints from customers who had relied on the information. Human quality control is not optional: it is a necessity.

Another aspect is that AI tools do not understand your brand, your tone of voice or your customers’ specific pain points. They generally generate content based on patterns in training data. Turning this content into something that actually represents your company and resonates with your target audience requires human insight.

This is what characterises a forward-thinking SEO agency

If you choose to work with an agency, it is crucial to choose the right one. Not all agencies have adapted to the new reality, and many are still operating using methods from 2018.

Use of AI for deeper data analysis and predictions

A forward-thinking SEO agency actively uses AI, but not as a shortcut to cheap content. They use it to analyse large amounts of data, identify patterns in user behaviour, and predict which trends will affect your visibility in the future.

At Mediabooster, for example, AI-driven data analysis is combined with over 15 years’ experience in digital marketing. This means that AI is used to process and interpret data more quickly, whilst the strategic assessment remains human. This combination delivers results that neither pure AI nor pure human analysis can achieve on their own.

In concrete terms, this could mean that the agency uses machine learning to analyse competitors’ content strategies and identify gaps in the market that you can exploit. Or that they use predictive models to estimate traffic potential for various content initiatives, so that you can prioritise what delivers the greatest return.

A good agency is also transparent about how they use AI. They explain what is automated, what is manual, and where human judgement comes into play. If an agency cannot explain this, you should ask questions.

Focus on user experience and conversion optimisation

SEO isn’t just about getting people to your website. It’s about what happens once they’re there. An agency that focuses solely on traffic without considering conversion is only doing half the job.

Forward-thinking agencies integrate SEO with user experience (UX) and conversion rate optimisation (CRO). They look at the entire user journey: from search to click, from landing page to action. They ask questions such as: Does the user land on the right page? Is the content tailored to their intent? Is the path to conversion clear and simple?

In practice, this means that the SEO agency works closely with developers and designers, not in silos. They understand that a page that ranks number one but has a bounce rate of 80 per cent does not deliver business value. They use data from Google Analytics, heatmaps and user surveys to improve the entire experience, not just the ranking.

This holistic approach is particularly important now that SGE can reduce clicks from search results. When fewer users click through, every single visitor counts for more. This places higher demands on the quality of what they encounter.

How to choose the right partner in a new digital landscape

Choosing an SEO agency in 2025 requires a different approach than it did five years ago. Here’s what actually matters when evaluating potential partners.

Look for an agency that understands your business, not just SEO as a discipline. They should ask questions about your business model, your target audience and what drives your revenue. If the first thing they talk about is keywords and links without understanding the context, that’s a red flag.

Assess their track record, but be critical. Ask for specific examples of results for businesses in situations similar to yours. General claims of ‘increased traffic’ are worthless without context. Ask which KPIs they measured, and how the traffic impacted the bottom line.

Understand their approach to AI. An agency that ignores AI is outdated. An agency that uses AI indiscriminately is risky. What you’re looking for is a partner that uses AI as a tool within a well-thought-out strategy, with clear quality control processes.

Check whether the agency offers training and knowledge transfer. The best partners make your team better over time, not more dependent. They teach you the basics of prompt engineering, help you understand the reports, and build internal expertise alongside the external work.

Finally: the chemistry has to be right. SEO is a long-term partnership. You need a partner you can have honest conversations with, who dares to say no when you suggest something that won’t work, and who celebrates when the results come in. Think of it as hiring a colleague, not ordering a service.

The question of whether you need an SEO agency in an era where AI is doing more and more boils down to this: do you have the expertise, capacity and strategic overview needed to compete in your market? If the answer is yes, AI tools may be all you need. If the answer is no, or if you’re unsure, a good agency is an investment that pays for itself many times over.
