Rheinwunder, the SEA agency in Bonn

SEA marketing that turns clicks into customers

We plan, manage, and optimise your campaigns in Google Ads and Microsoft Advertising: data-driven, transparent, and with a clear focus on your business objectives. This is how clicks turn into qualified enquiries and measurable revenue.

The right SEA strategy for your growth

We develop a SEA strategy that fits your business model, budget, and growth objectives. To achieve this, we research relevant keywords, structure your accounts neatly, and write ad copy that truly clicks in Google Ads, Microsoft Advertising (Bing), and other search engines.

Top placements when your customers search

With paid search ads, we position your offers exactly where your target audience is actively searching, even above the organic results. This ensures greater visibility, qualified traffic to your website, and significantly more opportunities for leads and sales.

Daily monitoring instead of campaigns flying blind

We do not simply let your campaigns run: We check the key metrics daily, test ads and keywords, and continuously adjust bids, budgets, and target audiences. This way, you optimise your advertising budget and improve performance step by step.

Why SEA for your business?

Win customers through search engine advertising with Rheinwunder

With Search Engine Advertising (SEA), we make your offering visible in search engines like Google and Bing, exactly at the moment when potential customers are searching for a solution. Instead of abstract traffic, it’s about measurable leads, sales, and enquiries, with clear objectives, precise tracking, and ongoing optimisation.

We explain the fundamentals of SEA in detail in our Wiki article “What is SEA?” and here we focus on what SEA with Rheinwunder can achieve for your business.

Quick, measurable results

In contrast to SEO, which has a more medium-term effect, SEA provides quick visibility. As soon as your campaign is live, your ads will appear in the search results. This is ideal for new businesses, seasonal offers, or short-term promotions where quick results are crucial.

Targeting people who are already searching

The great advantage of search engine advertising: You are addressing people who already want to solve a specific problem. Users have a particular search intent: they are looking for a solution, not for entertainment. SEA is your opportunity to present your product or service with finely tuned ads to exactly the people who need it right now.

Maximum flexibility in budget & setup

Search engine advertising can be adjusted at any time: increase or decrease budgets, test new campaigns, respond to seasonal fluctuations. Unlike many traditional channels, you see changes in the campaign structure reflected immediately in the results. This keeps you as a company flexible and able to respond quickly to the market.

Are you wondering if SEA is right for you?

Our experts will discuss with you, without obligation, how SEA can be utilised for your business and what results are realistic. Together, we will determine which strategy makes sense, or whether another channel is a better fit.

Bar chart of search engine market shares: Google 84.62%, Bing 7.57%, Yandex 2.43%, Yahoo 2.10%, DuckDuckGo 1.68%, Ecosia 1.27%.

Search Engine Advertising: Focus on Google

In Germany, according to current figures, around 85% of all search queries are made on Google. Bing, Yahoo, DuckDuckGo, Yandex & Co. share the comparatively small remainder. For businesses, this means: Those who are visible on Google reach the majority of potential customers in search.

With Google Ads, we place your offers precisely when people actively search for suitable products or services: in classic search, in the Shopping section, or in the network of partner sites.

As a certified Google Ads agency, we support you in covering relevant search queries, reducing wastage, and measurably achieving your business objectives.

Microsoft Advertising (formerly Bing Ads)

With Microsoft Advertising you can expand your visibility beyond Google and take advantage of an often underestimated search network. Particularly in the B2B and desktop sectors, there is exciting potential: additional reach, often lower click prices, and new customers that you cannot reach through Google. We will align your campaigns so that they seamlessly integrate into your existing SEA strategy and your budget is efficiently distributed across both platforms.

How we work as a SEA agency: 3 steps to measurable results

What does a SEA agency do?

As a SEA agency, we support you in being visible with paid ads in search engines like Google precisely when potential customers are actively searching for your services. We develop the appropriate strategy, set up technically sound campaigns, and ensure through ongoing optimisation that your advertising budget delivers the maximum return. In doing so, we focus not just on clicks, but on leads, enquiries, and revenue.

Analysis & Strategy

We analyse your starting situation, goals, and competitors, and examine what your target audience is actually searching for. From this, we develop a clear SEA strategy with suitable keywords, target groups, budgets, and KPIs, so that you know exactly how your advertising budget is being used.

Setup & Launch

We set up your accounts (e.g. Google Ads, Microsoft Ads) in a structured manner, create compelling ad texts and implement clean tracking. This ensures that from day one, only relevant users are targeted and every conversion is clearly measurable.

Monitoring & ongoing optimisation

We monitor performance daily and derive concrete optimisations, from keywords to budget. The aim is to reduce your cost per click and per conversion, increase the number of qualified enquiries, and continuously enhance the ROAS on your SEA budget.

Where the differences lie and which channel better suits your goals.

SEA and Social Ads are not competitors; rather, they complement each other because they target different stages of the Customer Journey.
The key differences at a glance:

Search Intent vs. Scrolling
SEA reaches people who are actively searching for a solution. Social Ads catch users in their feed who are not currently researching purposefully.
Performance vs. Reach
SEA is often the most direct route to measurable enquiries and sales. Social Ads are particularly suitable for brand building, inspiration, and re-engagement.
Keyword vs. Audience Logic
With SEA, you steer campaigns through search terms and bids. In Social Ads, the focus is on audiences, interests, and creatives.
Utilising Demand vs. Creating Demand
SEA leverages existing demand in search. Social Ads help to generate new demand and introduce audiences to your brand early on.

In many cases, the combination of both channels is the strongest option: SEA delivers quick, measurable results, while Social Ads provide additional visibility and demand.

What is SEA?

Frequently Asked Questions about Search Engine Advertising

Discover how to effectively reach your target audience and optimise your campaigns to achieve greater visibility and higher conversions.

How does SEA differ from SEO?

SEO optimises your website for organic search results, while SEA refers to paid advertisements in search engines. With SEA, you can quickly and very precisely gain visibility, manage budgets, and conduct tests, whereas SEO focuses more on long-term traffic growth. The most effective approach is the combination of both measures.

At what budget does SEA with Rheinwunder become worthwhile?

We do not work with a rigid minimum budget. A sensible advertising budget is one that allows for the collection of sufficient data and conversions, so that optimisations can truly take effect. In the initial consultation, we will jointly assess whether SEA aligns with your goals and conditions and provide a specific budget recommendation.

How quickly do we see results from SEA campaigns?

Once your campaigns are live, you will typically see initial clicks and enquiries within a few days. Whether the measures are economically viable can be better assessed after a few weeks, when sufficient data is available. We will clearly inform you which KPIs we are monitoring and from when we can make reliable statements.

Do you also manage existing Google or Microsoft Ads accounts?

Yes. We take on both completely new setups and existing accounts. Often, we start with a structured audit, tidy up campaigns and tracking, and highlight unused potential before we scale together.

Which platforms do you use in SEA?

We primarily work with Google Ads and Microsoft Advertising (Bing). Depending on the business model, we utilise search campaigns, Shopping product ads, remarketing and, if applicable, Performance Max campaigns. We discuss with you individually which formats are appropriate.

How do you ensure that our campaigns are profitable?

We set up clean conversion tracking, collaboratively define clear goals (e.g. cost per lead or ROAS) and continuously optimise your campaigns based on these metrics. In transparent reports, you can see exactly which measures deliver which leads, revenue, and ROI.

Are there minimum contract durations?

Whether there are minimum contract durations depends on the chosen setup and scope of services. What is important to us is a transparent collaboration: We discuss all conditions, notice periods, and trial phases openly in advance, so you know exactly what you are committing to.

Is SEA suitable for local businesses?

Yes, SEA is very effective, especially for local service providers, traders and locations. Through location, radius, and target audience targeting, we reach exactly the people in your region who are actively searching for your services and are ready to take action.

Do you also offer social media ads?

Yes. In addition to SEA, we also support many clients with paid campaigns on platforms such as META (Facebook & Instagram) or LinkedIn. This way, we reach your target audience across multiple channels. We would be happy to explain in a personal conversation how SEA and Social Media Marketing work together optimally.
