Search engines today work fundamentally differently than they did two years ago. Both the algorithms (Google AIO, AI Mode) and search behaviour (prompts instead of keywords) are evolving rapidly. What was successful yesterday may already be ineffective today.

Many companies are therefore seeking professional support from SEO agencies that also know how to optimise for LLMs such as ChatGPT. But what criteria are important when making your selection? Which agency is the best fit? And above all: who not only understands your product and your industry, but can also offer the right solutions for your specific challenges?

To make it easier for you to find the right agency, I have compiled a list of the best SEO agencies in Switzerland. This selection is based on recommendations from our network. For maximum fairness and transparency, all agencies have provided their own information.

Important: There is no such thing as the best agency.

But there are agencies that are better suited to your business, budget and order situation than others. Finding the right match – that's exactly what this article is here to help you with.

The agencies are sorted by Google ratings. I explain why this criterion (like many others) should be viewed with caution further down in the evaluation criteria.

11 SEO agencies compared

‍

[[callout]] Assessment Critera

How can I recognise a really good SEO agency?

These criteria will help you choose the right agency:

Industry Focus

Does the agency have a specific industry focus? The more experience, case studies and references it can demonstrate in your industry, the better. This is because SEO for e-commerce requires different strategies than SEO for a B2B SaaS company. Specialising in specific industries is therefore an advantage.

Technical Expertise

What SEO expertise does the agency have and what specific services does it offer? With full-service agencies, you should ask yourself: Is it realistic to expect them to deliver top performance in all the areas they offer? Carefully check whether the agency has the necessary expertise and all the skills required for your specific project.

Agency & Team size

How many employees work in the SEO area and what other services are offered? Is SEO the agency's main focus or just a side business? Larger teams can handle more projects in parallel, but the key question is: Do the processes remain lean and the collaboration agile?

Location & Language

An office in your city/region is not essential, but the agency must understand your market and target audience – and speak their language.

References & Reputation

Google reviews, testimonials and case studies give you an initial impression of whether the agency has already mastered challenges similar to yours. However, these are usually curated and superficial. Anonymous customer satisfaction metrics such as NPS or CSAT are more meaningful. But the most valuable references come verbally (do other marketers in your network recommend the agency?).

Innovative strength & future viability

Does the agency give presentations at conferences or offer webinars? How regularly does it publish content? Does it conduct its own studies or experiments and share the results? And how does it position itself on LLMs and AI?

Industry Focus

My answer to the frequently asked question of which strategies will be successful in the age of AI?

Technical Expertise

Meili & Hess offers services in the areas of SEO, SEA and web analytics. The approach is highly technical and focuses on audits, on-page optimisation and tracking rather than pure content marketing.

As a client, you work directly with the decision-makers and receive full transparency about who is responsible for which aspects of your project.

The agency sees itself as an interdisciplinary team that supports clients from strategy to implementation.

Agency & Team size

The team currently consists of eight people, four of whom deal with SEO issues. This means personal support, flat hierarchies and presumably close proximity to management. At the same time, with a company of this size, it is clear that not every discipline can be covered in depth. For e-commerce customers looking for close cooperation with a versatile agency, this may be just the right fit.

6. Rosarot

Rosarot is a somewhat larger creative agency based in Zurich. My information comes from Moreno Carroccia, who has over seven years of experience as Head of Performance.

Industry Focus

Rosarot does not focus on a specific industry. Instead, they work with a wide range of clients from various sectors. The focus is more on the range of services offered than on a specific market segment. This can be particularly relevant for companies looking for a versatile agency with cross-industry experience.

Technical Expertise

The range of services includes SEA, SEO, social media, campaigning and branding. SEO is one of several areas of expertise – embedded in a broader performance setup. Content plays a central role, especially when it comes to search intent and visibility. Technical SEO aspects such as indexing, loading times and page speed are also taken into account.

Agency & Team Size

Rosarot employs a total of 32 people, 2-3 of whom work in SEO. This is a solid line-up for performance-focused projects, but it also means that SEO is not the agency's main focus, but rather part of a larger range of services. For clients who want to work across multiple channels, this may be exactly the right setup.

Location & Language

The agency is based in Zurich, in the heart of the city on Albisriederstrasse. Its communications are primarily aimed at Swiss companies, although Moreno Carroccia has not provided any information on multilingual or international SEO setups. In terms of language and content, the service offering is heavily tailored to the Swiss market.

Industry Focus

According to its own information, SEO-Friends specifically targets B2B customers, primarily from the technology and industrial sectors. This specialisation is understandable, as it is precisely in these areas that the need for products requiring explanation and long-term visibility is particularly high.

Technical Expertise

At SEO-Friends, SEO is not just one of many services on offer, but the core service. Web development is also offered, but only in connection with SEO projects. According to the company, the focus is on sustainable organic growth through technical, content and strategic optimisation.

Agency & Team size

I currently have no information on the specific size of the team. One thing is clear: SEO-Friends is run by an experienced founder, presumably with occasional support in implementation. If you are looking for a small, directly managed SEO agency where the owner is also involved in operations, this is probably the right place for you.

Location & Language

The agency is based in eastern Switzerland, more precisely in Wil SG. This puts it in a good position to serve customers from German-speaking Switzerland.

References & Reputation

According to Daniel, he got started in SEO work through a project of his own:

The project remains one of his most important references to this day. For further references, it is best to contact Daniel directly.

Industry Focus

Webrepublic does not focus on any specific industry – the agency works with clients from various sectors, including retail, telecommunications, energy, healthcare and more. This brings methodological breadth, but also the challenge of having to familiarise oneself deeply with different industry logics depending on the project.
