Performance Marketing Agency with Technical Depth
Most agencies optimise campaigns. We optimise the entire system behind them.
Technical Expertise
Server-Side Tracking, Custom GTM Templates, automated feed optimisation. We solve the problems that others can’t.
Data-Driven Decisions
No gut-feel optimisation. Every measure is based on real data from GA4, Search Console, and your Ads accounts.
Custom Automations
Custom scripts for bid management, feed optimisation, and reporting. More performance with less manual effort.
ROI Focus
We optimise for conversions and revenue — not clicks or impressions. Your budget should work, not burn.
That’s why we don’t just work with Google Ads — we master all eight Google products, from data collection through tracking to conversion.
We also rely on automation and custom scripts that replace manual processes. This saves time and delivers results that are not achievable with standard tools. At the same time, all data stays with you — we work in your accounts, not ours.
Especially for companies that already run Google Ads but aren’t satisfied with the results, a technical analysis is worthwhile. The problem is often not in the campaign itself, but in the tracking, feed, or landing page. That’s why we start every partnership with a free audit of all relevant Google products.
What sets us apart is not the volume of budgets managed, but the technical depth of our work. We debug GTM containers, configure Server-Side Tracking, and optimise Shopping feeds — tasks where generic agencies fail. We work exclusively with white-hat methods and strictly adhere to Google’s guidelines.
Five Pillars for Measurable Growth
Each pillar works on its own. Together they deliver maximum impact, because SEA, SEO, GEO, AI and tracking reinforce each other.
From keyword research through ad creation to conversion optimisation. We don’t just analyse your campaigns, we also review tracking and landing pages. Without a clean data foundation, even the best ads are ineffective. You get not just better click rates, but also more qualified leads.

Technical SEO, content strategy and local SEO for organic rankings that last. We also integrate your SEO efforts with Google Business Profile and Search Console. This lets us identify indexing issues early and respond precisely. Especially for local businesses, this combination is decisive.

- Local SEO
- Google Business Profile
- Search Console
Your customers increasingly ask ChatGPT, Perplexity and Google’s AI summaries. We make your content quotable, your website readable for AI crawlers and your brand the recommendation. GEO builds on your SEO: the same data foundation, a new output format. With fixed prompts we measure every month whether and how you get named.

We build AI workflows for Google Ads, SEO, content and reporting: sorting search terms, drafting ad copy and feed titles, summarising reports in plain words. Every workflow uses your real data and rules and ends with approval by your team or us. Plus a clear data rule on which data may go into which tool.

- Ad copy
- Feed optimisation
- Monthly report in plain words

Without clean tracking, there are no good decisions. That’s why we set up GA4, Google Tag Manager and Consent Mode correctly, GDPR-compliant and complete. We also implement Enhanced Conversions and Server-Side Tracking so you don’t lose any conversion data. This automatically improves your campaign results too.

Focus: More self-pay patients, bookable appointments, local visibility
For example, we work with dental practices that attract new patients through local SEO and Google Business Profile. At the same time, we help trade businesses generate targeted inquiries from their region via Google Ads. The common denominator is always the same: measurable results and a clear return on investment.
We also support e-commerce companies in optimising their shopping feeds in Google Merchant Center. Faulty product data costs not just rankings, but also revenue. That’s why we systematically review feed quality, imagery, and landing page consistency in every project.

It’s not about using as many tools as possible. Rather, we ensure that all products work together cleanly. A GA4 setup without correct GTM tracking delivers wrong data — and consequently, your campaign decisions are based on faulty numbers. That’s exactly what we prevent.
You also benefit from our experience with Consent Mode v2. Many companies lose up to 30% of their conversion data through faulty cookie banner implementations. That’s why we review the consent configuration in every project — ensuring your data is collected completely and in compliance with GDPR.

What is Performance Marketing?
Performance marketing is a data-driven form of online marketing in which every measure is evaluated based on measurable results. Unlike traditional advertising, you don’t pay for reach, but for concrete outcomes — clicks, leads, or sales. Performance marketing is therefore particularly suitable for companies that want to use their budget efficiently.
Performance marketing also covers various channels: Google Ads (SEA), search engine optimisation (SEO), social media advertising, and affiliate marketing. The combination of paid and organic search is particularly effective — whoever is visible in both ads and organic results dominates the search results page.
Why Do I Need a Performance Marketing Agency?
A specialised performance marketing agency brings three key advantages: technical know-how, experience from hundreds of projects, and access to tools that would be too expensive for individual companies. The correct setup of tracking, conversion measurement, and attribution models in particular requires deep technical understanding.
Working with an agency also saves internal resources. Instead of training an employee, you immediately benefit from the expertise of a team that works with Google Ads, GA4, GTM, and Search Console every day. The investment in an agency typically pays off within the first 3–6 months.
How Much Does Performance Marketing Cost?
Costs depend on the scope of measures. At 1hold.de, the monthly flat rate starts from €800 for SEO consulting and from €500 for Google Ads management. It’s important to understand: agency costs are only part of the budget. In addition, there is the advertising spend for Google Ads, which goes directly to Google.
However, the decisive factor is not the absolute price, but the return on investment. A well-optimised campaign with a €2,000 monthly budget can be significantly more profitable than a poorly managed one with €10,000. That’s why we place great emphasis on transparency and monthly reporting of all relevant KPIs.
What Makes a Good Performance Marketing Agency?
A good performance marketing agency works transparently, data-driven, and with measurable goals. Look for the following criteria: Google certification, experience with your business model, clear reporting structures, and no long-term contracts. If the results are right, there’s no need for a contractual commitment.
A good agency should also not just run campaigns, but understand the entire digital ecosystem. This means: tracking implementation, landing page optimisation, and SEO are just as much part of the service spectrum as running ads. The integration of all Google products in particular is a quality feature that makes the difference.
Who is 1hold.de?
1hold.de is an owner-led agency for Google Ads, SEO, AI search visibility (GEO) and tracking based in Wiesbaden, Germany. Owner Kilian Müller has worked with Google Ads since 2011 and supports businesses in Wiesbaden, the Rhine-Main area and across Germany, from local firms to online shops. Every client has one dedicated contact. On Google, 1hold.de has a 5.0-star rating from 12 reviews.
