About ICS Cool Energy
ICS Cool Energy is a leading international specialist in process temperature control solutions and part of the Trane Technologies Group, also a long-standing WEVENTURE customer. With German locations in Augsburg and Zaberfeld, the company focuses on flexible rental solutions that keep industrial processes running around the clock across all industries and enable companies to respond to production peaks or emergencies in a capital-efficient manner.
The portfolio is divided into the core areas of rental cooling (chillers, process cooling, refrigerated containers) and rental heating (mobile heating centers, heat pumps, diesel heaters). Through its “eMission Critical” approach, ICS combines technical performance with the goal of increasing its customers’ energy efficiency and reducing their carbon footprint.
Step 1
The Challenge
Since August 2023, our paid team had been successfully managing ICS Cool Energy’s Google Ads campaigns, ensuring consistent traffic and sales. However, the situation changed abruptly when the parent company in the United Kingdom rolled out a new, centralized website for the whole of Europe in July 2024. What was intended as a simplification quickly turned out to be an obstacle for the German market.
To counteract the obvious content issues, our SEO and content team was brought in in August 2024. However, in the course of more in-depth analyses, we discovered that the problems went far beyond poorly translated texts: we were faced with major content, technical, and structural issues that massively jeopardized performance in the DACH region.
„Gratis Erfrischung“ statt High-End-Technik
The most obvious problem was the automated translation of the original English content into German, without any consideration for technical terminology. This led to grotesque stylistic blunders that not only looked unprofessional, but also deterred potential B2B customers.
The product category “Free Cooling” was particularly hard hit: the English term was not only translated as “free refreshment,” but also in other variations as “sale of free refrigeration machines,” “free cooling rental,” and “free rental of cooling equipment.” These errors suggested that ICS was simply giving away high-priced industrial technology, massively undermined the company’s technical expertise, and clearly showed that the content had been copied (and published) without being checked.
Sudden System Resets
In addition to the quality of its content, the platform suffered from technical instability. We observed sporadic page failures lasting up to 48 hours, during which the German site was completely inaccessible. The negative climax occurred in November 2024: an unannounced update accidentally reset (at least) the German part of the website to its July status. Translation errors that had long since been corrected (“free refreshment”) were suddenly back online, and customers were once again confronted with nonsensical texts. Since newly created product pages were simply deleted by the reset, our paid Google Ads suddenly led to nowhere (404 error). The problem was only fixed after a week.
Loss of visibility
The automatically translated content resulted in keywords that were not adapted to the search intent of the German market. For example, the word “Kessel” (English: boiler) is less common, whereas the term “Heizzentrale” (heating center) is more common. The result was a slump in visibility and organic traffic.
WordPress problems
Under the hood, the website was structured in a way that was problematic from an SEO perspective. The system pulled all menu items as H2 headings into the code of all pages. The result was pages with lots of H2s, but without a clear hierarchy. In addition, the template was extremely unstable: as soon as we tried to make texts more readable by using simple formatting such as bullet points or H3 headings, the entire text disappeared from the front end without a trace. We were forced to publish walls of text because any attempt at formatting destroyed the page.
UX dead ends
The user experience was a hurdle for conversions. Especially in the mobile view, users got stuck in a dead end because essential main categories such as “Products” or “Rental Solutions” were not clickable in the navigation. The situation was exacerbated by a dysfunctional “language selector” that trapped international visitors in an endless loop: attempts to switch to another language version often led back to the German home page – and vice versa.
Lack of flexibility
Working on content and user experience was like fighting a losing battle. The rigid WordPress template allowed for very few adjustments, which made it difficult to fix the above-mentioned problems. In addition, we lacked control over essential elements: contact forms were unreliable and disappeared after purely content-related changes to a page, and loading times were sometimes disastrous (up to 30 seconds) because we had no access to the server configuration. Any change that was not content-related had to go through IT, which made quick responses impossible.
Step 2
Our Approach
At first, we tried to salvage the existing system: obvious content errors were corrected manually and initial SEO patches were applied, although these measures were very slow due to the lack of flexibility in the WordPress system and seemed more like a drop in the ocean. But November 2024 marked a turning point: an unannounced system update reset the German site to an old version. For a whole week, the “free refresh” returned, while our team was powerless to do anything about it. This incident made it clear that cosmetic corrections alone were not enough. In close consultation with management, a strategic decision was made in March 2025: ICS Cool Energy Germany needed its own, technically independent platform. What followed was a radical change and a complete rebuild of the digital infrastructure.
Parallel to the creation of the website, we also fundamentally transformed the SEA strategy. The goal was no longer reach at any price, but measurable sales quality.

Step 3
WEVENTURE delivers Results
The decision to spin off and focus on quality rather than quantity has paid off. The figures show not only stabilization, but also good growth in efficiency and visibility. At the same time, it is clear that there is further potential, particularly in the organic area, as the website is gradually evolving after its relaunch and, based on experience, its full SEO potential will only unfold as it matures.

Learnings
Key Insights
- AI translations are a business risk: The translation error surrounding “free cooling” arose from the ambiguity of the English word “free,” which, depending on the context, can mean ‘free’ (in the sense of freely available ambient air in free cooling) or “free of charge” or “gratis.” Without technical expertise and contextual review, the translation system interpreted the term purely semantically rather than technically – a classic example of the limitations of generative AI: it recognizes probabilities in language, but does not automatically recognize industry-specific meaning if there is no clear contextual guidance or editorial control.
- Localization beats globalization: A centralized “one-size-fits-all” website for Europe can fail to meet the specific requirements of the German B2B market. Local trust signals and a culturally adapted UX are essential for business success in Germany, Austria, and Switzerland.
- Technical sovereignty is the performance driver: Without direct access to servers, CMS, and plugins, agile SEO is impossible. Dependence on sluggish, centralized IT structures prevented quick responses to bugs.
- Data quality over click volume (offline conversion tracking): The key to reducing CPL (-19.3%) was moving away from mere “form submissions” to validated CRM data (MQLs/SQLs). Only by feeding real sales data back to Google Ads was it possible to shift the budget from “lucky dips” to genuine potential customers.
- Stability protects your media budget: A technically unstable website actively burns money. When landing pages turn into 404 errors overnight due to updates, paid ads run into a void. A stable redirect concept and server control are insurance for every advertising budget invested.
- Seasonality requires agility: Rigid budget planning has been replaced by dynamic shifting models. The ability to shift budgets between “heating” (winter) and “cooling” (summer) at short notice is crucial to efficiently exploit peak demand in the industry.
- SEO requires patience, but pays off exponentially: As expected, the domain change led to a brief dip in visibility, but this was quickly offset by clean technical work. Organic traffic is more sustainable and cheaper in the long term than purchased traffic and, as in our example, also leads to lead generation via AI searches such as ChatGPT.
