Choosing an SEO agency is a decision that determines your company’s online visibility. We show you how to verify a potential partner’s expertise and what to look for so that SEO translates into real sales growth.

SEO agency Toruń: how to tell real expertise from marketing fluff

The SEO services market in the Kuyavian-Pomeranian region is saturated. It's easy to come across companies that sell "guarantees of Google's first page" or operate with empty slogans. Meanwhile, effective website positioning Toruń is a process based on data, analysis, and long-term strategy, not intuition. As J. Scott Armstrong writes in "Persuasive Advertising: Evidence-based Principles" (2010), advertising and marketing actions based on empirical evidence are more effective than intuitive practices. This principle translates perfectly to choosing an SEO agency: it's worth looking for a partner who can show concrete case studies and metrics, not just talk about "innovative methods."

The first step is to verify whether the agency understands the specifics of B2B business. Positioning an e-commerce store follows different rules than positioning a manufacturing or service company. In B2B, the sales cycle is longer, and purchasing decisions are based on rational reasons. Therefore, the agency should focus on attracting traffic with conversion potential, not just on visit numbers. Ask a potential partner how they measure lead quality and how they optimize the purchasing path. A good sign is familiarity with the Customer Journey Design (CJD) model, which, according to research by Kuehnl, Jozic, and Homburg (2019), increases customer loyalty by building a positive attitude toward the brand. Thematic consistency, coherence, and context sensitivity are key dimensions of effective customer journey design that should be visible in the SEO strategy.

Also verify whether the agency has experience in your industry. It's not about knowing all the technological nuances, but about understanding the language of benefits and being able to reach decision-makers. It's worth asking what content they create and whether it is tailored to the stage of the sales funnel where the potential customer is. Remember that positioning is not just links and keywords, but above all building trust and authority in the eyes of Google and users.

Positioning websites Toruń: the cooperation model matters

There are two main cooperation models with an SEO agency on the market. The first is full agency service, where the agency takes responsibility for all activities: from audit, through technical optimization, to content marketing and link building. The second model is an interim marketing manager, an experienced specialist who joins the team for a specific period and achieves specific goals. This second model, settled based on results, is particularly attractive for companies that want to build internal competencies or need support in a specific project but do not want to engage an entire marketing department right away.

The choice of model depends on your needs and budget. Full agency service offers comfort and saves time but requires a larger financial commitment. An interim manager is a more flexible option, allowing for quick implementation of changes and control over the process. In both cases, it is crucial that the agency clearly defines goals and measures results. Avoid companies that offer "packages" without specifying exactly what they include and what metrics will be considered when evaluating effectiveness. As research in "Advances in Advertising Research IX" (Cauberghe, Hudders, Eisend, 2018) shows, in B2B content marketing, behavioral engagement (e.g., clicks, shares) is a key mediator between activity and business results. Therefore, the agency should report not only keyword positions but above all traffic, leads, and sales.

It is also worth paying attention to whether the agency proposes activities that go beyond standard SEO. Nowadays, effective positioning requires integration with social media, content marketing, and performance campaigns. As the authors of "Social Media Marketing: Emerging Concepts and Applications" (Heggede, Shainesh, 2018) note, social media changes the role of marketing from one-way communication to a real-time dialogue with the customer. An agency that can use this potential is able to build lasting relationships with customers and strengthen the effects of SEO activities.

Social proof and evidence of credibility in choosing an SEO agency

Choosing an SEO agency is a decision fraught with risk. Therefore, it is natural to look for confirmation that a given company is trustworthy. In social psychology, this mechanism is called social proof. As J. Scott Armstrong explains, showing that a product or service is widely used increases the propensity to buy. In the context of choosing an SEO agency, this means it is worth paying attention to references, customer reviews, and case studies. If the agency has collaborated with recognized brands from the region, that is a good sign. But be careful: do not be fooled by appearances. Ask for contact to clients who can talk about the cooperation and ask about specific results.

When verifying an agency, pay attention to how long it has been on the market and what experience it has. A company with 16 years of experience, which has managed budgets worth 160 million PLN and served over 60 clients, has a completely different perspective than a newly established startup. Such data, if true, indicate stability and the ability to adapt to changing market conditions. Remember, however, that numbers are not everything. The key is whether the agency can translate its experience into concrete benefits for your company. Ask about the challenges it faced with similar clients and how it solved them.

It is also worth checking whether the agency is active in the local business ecosystem. Presence at industry events, expert publications, or cooperation with local organizations is a signal that the company is engaged in the development of the region and understands its specifics. This is important because a marketing agency operating locally has better insight into the local market and can more effectively reach your potential customers.

How to measure the effectiveness of positioning? Customer journey and data

Measuring SEO effectiveness solely by search engine rankings is an outdated approach. Modern SEO is a process that should lead to achieving business goals, such as increasing sales or generating leads. Therefore, it is crucial that the agency and the client jointly define the KPIs that will be evaluated. These can include: number of unique visits, time spent on the site, conversion rate, number of filled contact forms, or the value of generated orders.

In this context, the Customer Journey Design (CJD) model is extremely helpful. According to research by Kuehnl, Jozic, and Homburg (2019), effective customer journey design increases loyalty by building a positive attitude toward the brand. CJD focuses on the process: how the customer moves through touchpoints with the brand, from the first visit to the site, through analyzing the offer, to the purchase decision. An SEO agency that understands this process can better tailor content and optimize the site to user needs at every stage. This way, SEO becomes not only a tool for gaining traffic but also for building lasting customer relationships.

It is also worth paying attention to how the agency reports results. Does it provide regular reports that are understandable to a non-technical person? Can it explain why some actions bring better results while others need adjustment? Transparency and communication are the foundation of good cooperation. Avoid agencies that overwhelm you with complex data without drawing conclusions. A good partner should be able to present results in the context of your business goals and propose next steps.

The chart below illustrates what a B2B customer journey might look like in the context of SEO activities and which metrics are worth measuring at each stage.

Common mistakes B2B companies make when choosing an SEO agency

Choosing an SEO agency is often a process based on emotions and superficial criteria. Here are the most common mistakes B2B companies make:

  • Basing the decision solely on price.The cheapest offer is rarely the best. SEO is an investment that should pay off in increased revenue. A price that is too low may mean the agency uses cheap but risky techniques that can harm your site in the long run.
  • Failing to verify competencies.You do not check the agency's case studies, references, or experience. It is like hiring an employee without an interview. A business owner signs a one-year contract after a single phone call because the agency "sounded professional" and had a nice PDF presentation. Three months later, they ask for references: it turns out the only client provided parted ways with the agency after a quarter, and the phone number in the case study is outdated.
  • Focusing on rankings, not on business.Ranking number one for a keyword does not matter if it does not translate into inquiries. What counts is the quality of traffic, not its quantity.
  • Lack of clearly defined goals.You do not know what you want to achieve, so the agency does "whatever." The result? You waste budget and time. At the first meeting, the agency asks: "What are your goals?" The owner replies: "Well, to be higher in Google." Three months and a few thousand later, the company is higher in Google: for keywords that none of the customers ever type in, because no one asked what phone should ring.
  • Ignoring technical aspects.SEO also includes page load speed, mobile optimization, header structure, and technical correctness: not just content. If the agency does not pay attention to this, run away.

As research by Czinkota, Kotabe, Vrontis, and Shams shows ("Marketing Management: Past, Present and Future," 2021), marketing is a practical discipline based on dialogue with the customer, not just theoretical models. So when choosing an agency, focus primarily on its practical approach and ability to listen. A good partner is one who asks questions, analyzes your situation, and proposes tailored solutions, rather than pushing a ready-made product.

The chart below compares two SEO agency collaboration models that are most often chosen by B2B companies.

Comparison of collaboration models with an SEO agency
Full agency serviceInterim marketing manager
Scope of workComprehensive: from audit to reportingFocused on a specific project or goal
CostsFlat monthly feePerformance-based pricing or hourly rate
Time to implementationRequires time for onboarding and getting to know the companyFaster implementation, specialist joins immediately
ControlLess: the agency takes responsibilityMore: the client retains control over the process
Building competenciesLimited: knowledge stays within the agencyKnowledge transfer to the internal team

In summary, choosing an SEO agency is a strategic decision. Do not be fooled by promises of quick results and "guaranteed first page." Instead, look for a partner who bases its actions on evidence, understands the specifics of your business, and can measure results in the context of business goals. Only such an approach will ensure lasting growth in visibility and a real return on investment.
