Google Ads Agency Heidelberg • SEA & Performance Marketing

Google Ads & Performance Marketing Agency Heidelberg

Google Ads that target margin –
not clicks.

We manage campaigns by what is left at the end: margin and customer value. The foundation is server-side tracking that measures accurately, and tests that are only called once the numbers support them.

disciplines

Four paid channels, centrally managed.

Anyone running Google Ads seriously today is dealing with several ad placements. We manage them together so they don't steal conversions from one another.

G
01

Google Search

Classic search adverts, where we precisely control keywords and match types and continuously maintain the negative keyword lists. Search delivers the highest conversion rate of all channels.

P
02

Performance Max

A well-thought-out asset group architecture rather than a scattergun approach. We manage PMax with clear audience signals and a clean conversion hierarchy.

D
03

Display & YouTube

This is about awareness and retargeting. We build custom audiences from first-party data instead of guessing at target groups.

B
04

Bing / Microsoft Ads

CPCs 15–25% lower in the B2B segment. We systematically use Bing where the target audience uses Microsoft 365.

tracking stack

Accurate tracking accounts for 90 per cent of the work.

Before we move a single euro of budget, the tracking is in place: server-side via GTM Server, with Enhanced Conversions and offline import from the CRM. That way every click can be attributed to a lead source and a customer value.

Without this foundation, you are optimising on data you don't actually have. With it in place, every budget decision can be justified. Just as important is where the click leads: an ad is only as good as the landing page behind it.

We run ads for SaaS, SMEs, D2C and lead generation. The approach stays the same; the execution is closely tailored to the market and the margin model.

Campaigns that someone actually manages.

With us, your account doesn't run on autopilot. A real person checks it every day and steps in before budget goes up in smoke.

approach

How our work differs from that of many agencies.

01 · Tracking First

Clean setup before budget

We don't launch an account until server-side tracking, Enhanced Conversions and offline imports are in place. Without them, we wouldn't know which clicks actually turn into customers.

02 · CLV, not clicks

We optimise for value, not volume

Conversion values weighted by CLV per segment. A €200 conversion in segment A is not the same as one in segment B.

03 · PMax with discipline

Asset groups instead of a black box

PMax can be brilliant or disastrous, depending on the setup. We build asset groups with clear audience signals and a conversion hierarchy.

04 · Tests with statistical significance

Numbers, not impressions

Tests run until the result is statistically robust (95 % significance), not just for a week. With clear stop-loss logic as soon as a variant is clearly losing.

05 · Weekly review

Hands-on & transparent

We have a short call with you every week and an in-depth strategy discussion once a month. You also get a Looker dashboard that you can read without us explaining it.

06 · Integration with SEO

Both channels inform each other

Keywords that rank organically need less ad budget. Terms that convert via ads become targets for our SEO work from Heidelberg. With us, the same team manages both - and uses the data in both directions.

faq

Frequently asked questions about working with us on performance.

From what monthly ad budget is agency management worthwhile?

Realistically from €3,000 ad spend per month. Below that, the cost of management rarely bears any relation to the potential impact. In that case, we tend to recommend our audit plus setup, which your team then runs itself.

Who controls the ads account and the creatives?

The account always remains your property. We receive admin rights; you keep owner status. Creatives are supplied by us or by your team, depending on the setup. If you switch or end the engagement, we hand everything over cleanly, with no "black box".

How quickly will we see optimisation results?

First valid data after 14–21 days. Statistically significant optimisation effects after 4–8 weeks. Anyone who shows you results after 7 days is showing noise, not signal.

Do you offer performance guarantees?

No, no percentage guarantees. We guarantee audit quality and tracking set-up. No reputable provider can be held liable 1:1 for performance, as the market, competition and seasonality always play a part. What we promise: an honest assessment every month, with clear recommendations for optimisation.

What if our existing agency carries on and you only do the audit?

That works. Audit + 60-minute walkthrough at a fixed price. You receive a list of the three biggest levers, which your current agency can then pick up. Our only gain is giving you an honest assessment.

Do you also work with affiliate or comparison websites?

Yes, but with caution. Affiliate funnels have very specific tracking requirements. We manage performance marketing for our own affiliate projects, which you can find in our case studies, and this knowledge informs our work with clients. However, we are not a specialist affiliate agency.

How does performance marketing differ from traditional online marketing?

Performance marketing is the part of online marketing in which every activity contributes measurably to specific KPIs: leads, conversions, revenue, ROI. A traditional marketing agency often thinks in terms of brand strategy and measures reach. We take a data-driven approach along the customer journey - from the first search query through every touchpoint to the sale. Both have their place, but how success is measured is fundamentally different.

Which channels do you cover besides Google Ads?

The core is search engine advertising (SEA): SEA campaigns via Google Ads and Microsoft Advertising. On top of that comes paid social via Meta, i.e. Facebook and Instagram, and TikTok for suitable audiences. We use social media advertising where search volume is lacking or the audience can be reached more cheaply. We recommend email marketing and newsletters for retaining existing customers, while content marketing and search engine optimisation are handled by our SEO team. What we don't offer is social media marketing as ongoing editorial and community work - we'd rather say so up front than after the fact.

Who benefits from a performance marketing agency in Heidelberg?

Businesses whose model depends on predictable enquiries or online sales: local service providers, B2B suppliers, e-commerce. The advantage of an online marketing agency in Heidelberg over purely remote support lies less in geography than in market understanding: we know the competitive landscape in the region and can assess potential realistically. Whether we are the right fit for your case is something the free initial consultation will clarify - ongoing management across all channels only makes sense once tracking and campaign structure are in place.

heidelberg

Google Ads agency in Heidelberg – serving the region and beyond.

As a Google Ads agency from Heidelberg, we manage Google Ads campaigns for businesses in Heidelberg and the Rhine-Neckar Metropolitan Region - from the local service provider who needs leads within a 20-kilometre radius to the B2B supplier with a nationwide funnel. Especially for an SEA agency working with local clients, targeting is what makes the difference: precise geo-targeting, relevant ad copy with a local angle and landing pages that match the search query, rather than burning budget on wasted reach. After all, the traffic should turn into enquiries and more revenue.

Many still know the channel as Google AdWords - it has been called Google Ads since 2018, but the mechanics are the same: the Quality Score, made up of ad relevance, expected click-through rate and landing page experience, helps determine what you pay per click. That is where we start. We structure your Google Ads account cleanly, continuously improve conversion rate and Quality Score, and only scale once performance tracking via Google Tag Manager and server-side tracking genuinely measures what a lead is worth. The same transparency applies to reporting: you see the same KPIs we do.

Alongside classic search, we run Google Shopping and Performance Max for e-commerce, video ads on YouTube for remarketing, and Facebook Ads and social ads when the audience can be reached more cheaply there. And an honest word on badges: whether an agency is listed as a certified Google Partner or Google Premier Partner mainly says something about the budgets it manages - how competently your account is run shows in the account itself. We would rather be measured by results, and in the initial consultation we will advise you, with no obligation, on what potential is lying untapped in your account.

We compare which channel is better suited to your offering in Google Ads vs Facebook Ads. The self-assessment Am I ready for Facebook Ads? helps you determine whether your business is ready for campaigns on Meta; our service package for this is detailed in the Facebook Ads offer. You can use the ROI calculator to work out what a campaign needs to deliver given your budget.

As a performance marketing agency in Heidelberg, we are deliberately not a full-service digital agency with twenty different disciplines. We focus on channels whose impact can be measured. Every performance marketing strategy we create is built for the individual business and begins with analysis: which audience do you want to reach, which touchpoints make up the customer journey, where is potential going unused? From this we develop a campaign structure aligned with your goals. We then continue conversion optimisation on an ongoing basis, rather than building the setup once and leaving it. The goal is greater visibility in search engines and high-quality leads, not simply more traffic. That includes better conversion rates and a scalable, data-driven setup whose ROI you can track yourself in the dashboard. Many Heidelberg businesses come to us after a marketing agency delivered clicks, but no one could show what turned into revenue.

SEO and Google Ads work best together: what the campaigns learn in terms of search terms and conversions feeds directly into our search engine optimisation – and vice versa. The SEO vs SEA comparison shows when which channel takes priority. With expertise gained from over 150 projects since 2016 and landing pages that convert, we create efficient online marketing that pays off as a whole.
