SEO services for serious growth.

Technical SEO, topical authority, content hubs and link building from real agency practice. Good rankings don't happen overnight, but once they are in place, they carry you for years. That is exactly the kind of substance we build, rather than chasing the next trend.

Four SEO service areas.

We don't split SEO into twenty mini-packages. There are four clearly defined areas, and they work hand in hand.

T

Technical SEO

Google needs to be able to crawl and index your pages cleanly, the Core Web Vitals have to be right, and so does the schema. With technical SEO we lay the foundation that everything else needs before it can rank at all.

C

Content & Authority

We plan topical authority maps and content hubs and write concrete briefs for them. Genuine E-E-A-T signals count for more than any particular word count.

L

Local SEO

Local SEO with Google Business Profile, city pages and NAP consistency for location-based businesses and multi-site operators.

O

Off-Page & Backlinks

We rely on digital PR; we don't use bought link networks. In outreach, we look at whether a link fits your topic rather than at its metrics.

process

How an SEO project works with us.

Four phases with clear expectations and transparent reports. You can see at any time what we’re working on and why.

01 · Audit

Data first

We review technical aspects, content and backlinks. You will receive a 40-page PDF setting out prioritised areas for improvement.

02 · Strategy

Roadmap with KPIs

A 12-month plan sets out which topics we will tackle, in what order, and how we will measure success.

03 · Build

Implementation with you

We have a short check-in with you every week. Content briefs and technical implementation run in parallel.

04 · Iterate

Scaling & optimisation

Every month we analyse the figures, and once a quarter we adjust the strategy. That way, your visibility holds well beyond the first successes.

Dedicated contacts, no ticket ping-pong.

You speak with the people who actually do your SEO - not with an account manager who has to pass every question on first.

What makes for good SEO services.

Search engine optimisation is not a one-off project that is finished after the relaunch, but ongoing work on the foundation of your online presence. Search engine optimisation, or SEO for short, ensures that your website appears in the results of search engines such as Google where your customers are actually searching. We don't promise guaranteed top positions, because no one can credibly control every Google algorithm. What we deliver is solid craftsmanship without the sugar-coating.

Professionally set-up SEO services combine several interlocking disciplines: keyword research, technical SEO, on-page optimisation, content creation around relevant search queries, and off-page optimisation through link building from credible sources. Only when these work together do you get the organic visibility that brings measurably more traffic and qualified leads to your site, rather than just moving numbers in a dashboard. Whether you call it SEO services, an SEO service or simply search engine optimisation, it always means the same continuous work to make your business easier to find in search engines such as Google.

Tailor-made rather than off-the-peg

An online shop in e-commerce requires a different strategy to a local service provider or a B2B company with lengthy decision-making processes. That is why we do not work with standard packages, but with a bespoke strategy and a roadmap tailored to your business. This applies to SMEs as well as to larger medium-sized enterprises, and also to special cases such as Shopify SEO in e-commerce, where collection pages and filter URLs have their own specific rules. We analyse where your competitors stand online, which keywords are realistically achievable, and where the greatest potential for boosting your traffic lies.

  • Understanding search engines: We set up your website so that crawlers capture content cleanly and classify it correctly.
  • Relevant keywords: Instead of targeting vanity terms, we focus on search queries with genuine purchase intent.
  • Content with substance: Content marketing copy that answers your target audience's questions and so builds trust with users and search engines alike.
  • Connection to the rest of your online marketing: SEO works best when it is aligned with your other channels, such as social media and paid advertising.

Where artificial intelligence comes in

Artificial intelligence is currently changing how people search. Answer engines such as ChatGPT and Perplexity, as well as the AI Overviews from Google LLC, draw their answers from content that traditional search engines already rate as reliable. If you are visible in search results today, you are also better placed in tomorrow's AI-powered answers. That is why we plan SEO and AI-GEO together: both build on the same foundation, and that foundation also ensures visibility in the long term.

SEO and SEA: working together, not either-or

Paid ads via Google Ads bring instant reach, but every click costs money, and visibility ends when the budget does. Organic traffic from search engine optimisation takes longer, but it works in the long term and becomes ever cheaper per visitor. In practice, SEO and SEA complement each other well: SEA quickly provides data on which keywords actually convert, and these insights feed into the SEO strategy. If you compare the return on investment of both channels side by side, you will usually find that better rankings in search results are the more economical route over time, without making paid advertising redundant.

SEO agency, freelancer or in-house team?

When it comes to SEO, you essentially have three options: a specialised SEO agency, an SEO freelancer or your own in-house team. SEO agencies in Germany differ widely in their approach and quality, so it pays to take a close look before hiring one. A reputable agency shows clearly which SEO measures it implements, works with transparent reporting and doesn't promise guaranteed rankings. Professional search engine optimisation doesn't stop after launch: ranking monitoring, continuous content adjustments and building high-quality backlinks take time and experience. Freelancers can be the right choice for clearly defined tasks, and an in-house team for companies with a consistently high demand for content. For most mid-sized companies, an agency with a well-established team is the most pragmatic route to measurable results.

How we work as an SEO agency in Heidelberg, including our process, packages and examples, is set out on our main search engine optimisation page.

faq

Frequently asked questions.

How much do you charge for SEO?

That depends on the scope: the size of the website, the competition and the number of topics. The retainer has a minimum term of 90 days. You will receive a concrete proposal after the SEO audit.

When will we see results?

Technical fixes take effect within 2–6 weeks. Content-driven growth takes 6–9 months for Google to build trust. If someone promises you “results in 30 days”, you should be sceptical.

Do you only work with big brands?

No. We work with companies from an annual turnover of around €2 million, where SEO pays off. For very early-stage start-ups, we recommend building in-house or using a freelancer network.

Do you also do international SEO?

Yes. The DACH region is our focus, and we regularly handle international projects (English, Polish, Dutch) with hreflang setup and local content briefs.

What exactly do your SEO services include?

We cover the full spectrum of search engine optimisation: technical foundations, content optimised for relevant keywords and link building. The aim is a stable online presence that remains visible in search results and drives qualified traffic. The specific components required depend on your current situation and the competition, which is why we tailor each project individually.

How can you recognise a reputable SEO provider?

By transparency. A reputable SEO provider explains what they are doing and why, delivers regular reporting and gives realistic timeframes instead of ranking guarantees. Check reviews on independent platforms, ask about their specific approach to link building, and be wary of mass offers via cold outreach. Anyone advertising bought link networks or "secret methods" is putting your search engine visibility at risk rather than building it.

How do you measure the success of your SEO work?

Through metrics that matter for your business: organic traffic, rankings for the relevant keywords, leads and ultimately revenue. You receive a monthly report with ongoing monitoring of the most important positions. If a measure falls short of expectations, we adjust the strategy and communicate this openly rather than dressing up the figures. That way, results stay measurable and the collaboration stays transparent.

Which tools do you use?

We use established tools such as Google Search Console, Semrush and Screaming Frog for data and analysis. We use artificial intelligence selectively for research and content preparation, never for unchecked mass-produced text. Strategic decisions are made by people who can read and interpret your search data.
