How OHBAU Transformed Three Websites into One Measurable Digital Platform
A corporate website for glass construction, metal construction, photovoltaics, and assembly systems – enhanced with calculators, AI-powered knowledge architecture, B2B signals, and direct contact paths.
The platform launched in December 2025 and has since been continuously expanded and improved based on measurable usage in real customer operations.
Measurable Results in Ongoing Operations
The following values are from Google Search Console and self-hosted Matomo. They show real platform usage, not projections.
56,339 Impressions
Google impressions in 90 days. This represents a growth of 26.8% compared to the previous comparison period.
1,175 Organic Clicks
Clicks from Google Search in 90 days. This is 10.2% more than in the previous 90-day period.
1,738 Matomo Visits
1,738 visits and 4,815 page views from August 12 to November 9, 2026 – an average of approximately 135 visits per week.
Three Websites Become One Platform
The content and existing visibility of the previous sites were combined into a shared information architecture.
New Expert Answers Are Found
The new answer regarding building permits for patio roofs immediately achieved 2,122 impressions and 17 clicks.
Approximately 100 Qualified Visitors
After deducting technical and less relevant access, OHBAU conservatively estimates approximately 100 visits per week as qualified.
Sources: Google Search Console and self-hosted Matomo, accessed on November 9, 2026. GSC periods each comprise 90 full days. The classification of qualified visits and daily direct contacts is an operator assessment.
Four service areas, but no common digital logic
Oberhauser Bau-Systeme combines craftsmanship, planning, and installation: glass construction and roofing, metal construction, photovoltaic systems, and self-developed PV mounting systems. Before the relaunch, content and visibility were spread across three previous websites. The already successful domain oberhauser-pv.de had to be preserved.
The task was therefore larger than a redesign: secure existing reach, clearly separate offerings, bundle projects from multiple sources, and integrate new digital tools in a way that genuinely supports sales and consulting.
Project goal: A website that informs, calculates, qualifies, shortens contact paths, and provides new insights for further development.
Real offerings, real manufacturing, real projects: The digital structure follows the company's business areas.
The website as a connected system
Instead of individual landing pages, a knowledge and sales network was created. Content, tools, projects, and measurement data support each other.
Service Pages
Glass construction, metal construction, photovoltaics, and mounting systems are clearly separated but meaningfully linked.
Reference Hub
The hub bundles projects from multiple sources and continues to integrate the existing reach of oberhauser-pv.de.
Answer Engine and RAG
Expert knowledge is published as verifiable, indexable answers with sources, context, and relevant service references.
Calculators and Tools
The PV calculator and other functions make the benefits tangible even before the first personal contact.
Matomo and Search Console
Search demand, page views, and user journeys provide the data for controlled improvements.
What was actually developed and integrated
More than 14 project-specific modules work together within the existing WordPress system. The most important examples:
MiniRAG / Answer Engine
Indexable expert answers in clear topic areas, with independent URLs, short answers, detailed context, internal links, OpenGraph, and structured data.
Reference Hub
Aggregates local and external projects, normalizes metadata, and provides them as a filterable gallery.
PV Calculator
An interactive yield and self-sufficiency calculator translates complex assumptions into understandable results.
Contact FABs
Phone, email, WhatsApp, and contact options remain contextually accessible, shortening the path to the relevant department.
Company Resolver
The Matomo plugin combines ASN, RDAP, and Reverse DNS, evaluates signals with confidence, and creates data-efficient B2B insights.
SEO, Media, and Operations
Image metadata, gallery SEO, SMTP, cookie consent, redirects, link checking, security, and local fonts were combined into a maintainable overall operation.

Photovoltaik-Ertragsrechner: Ertrag, Autarkie und Stromkosten berechnen
Jahresverbrauch, Anlagenleistung, Speicher und Standort eingeben: Der OHBAU-Rechner zeigt PV-Erzeugung, Autarkiegrad, Eigenverbrauch und die mögliche jährliche Stromkostenersparnis.
From Business Idea to Functional Software
- Understand the problem: What decision should the tool facilitate?
- Model the business logic: Formulas, rules, assumptions, and limitations are defined collaboratively.
- Develop a prototype: The idea quickly becomes testable as an operable function.
- Test with real data: Plausibility, input limits, and result presentation are checked.
- Integrate into WordPress: The tool fits into content, design, and user guidance.
- Measure and improve: Usage and feedback guide further development.
AI does not replace specialized knowledge. It accelerates the translation of a business idea into testable code. Responsibility, review, and approval remain human development work.
How Existing Content Becomes Citable Answers
Reliable Sources
Service pages, projects, technical documentation, and verified external standard or legal sources form the basis. Each answer specifies the concrete service and a suitable next step.
Retrieval Instead of Free Invention
A question is assigned to topics and suitable documents. Only this filtered context is used for the answer. This reduces hallucinations and keeps statements close to the company.
Answer Engine and RAG in Live Operation
Indexable and Machine-Readable
Important questions receive their own URLs, clear short answers, detailed explanations, internal links, and structured data. People, Google, and AI systems can understand the same reliable content.
A Controlled Learning Cycle
Search Console shows new search needs; Matomo shows actually used pages and paths. Editorial decisions remain controlled. The system grows dynamically, but not unsupervised.
Privacy-Conscious B2B Signals Instead of Anonymous Page Views
The Company Resolver was developed as its own Matomo plugin. It evaluates technical company signals and separates reliable clues from providers, bots, and uncertain hits. It does not identify individual persons, but provides prioritizable signals for human sales review.
ASN and Network Range
Technical network data provides the initial organizational context.
RDAP and Organization
Registration data supplements comprehensible information about the potential organization.
Reverse DNS
Hostnames can provide additional clues without inferring a person.
Classification
Providers, bots, companies, and uncertain results are evaluated separately.
Confidence and Report
The origin and certainty of each signal remain visible for review.
Sales Review
Only a human decides if and how a clue is commercially relevant.
Information Overload Becomes Reviewable Opportunities
The AI Tender Monitor follows the same principle: capture sources, normalize content, filter by business relevance, justify hits comprehensibly, and only then submit them for human decision. For OHBAU, trades, region, deadlines, and project type are crucial.
- No autonomous bidding and no invented hits
- Source link and decision basis remain visible
- Technical approval before any sales action
- Transferable to other industries and data sources
Digitalization is not an end in itself here: it supports real products, projects, and contacts.
What Other Companies Can Learn From This
Website first, tools where they help
The strongest platform isn't built from as many AI features as possible, but from high-performing pages complemented by tools that solve real customer questions.
Proprietary data becomes an advantage
Projects, expertise, search queries, and usage data are more valuable than interchangeable AI texts. RAG makes this inventory discoverable and citable.
Small software can have a big impact
A calculator, an intelligent project search, or shorter contact paths can deliver more business value than another static campaign page.
Frequently Asked Questions about the OHBAU Platform
Is OHBAU a website or a custom software solution?
Both. WordPress provides editorial functions, user management, and a stable ecosystem. Custom plugins add business logic that standard products don't cover: project aggregation, expert answers, calculators, contact control, and B2B analysis.
Can a WordPress website serve as a RAG system?
Yes. Content requires clear sources, stable URLs, metadata, thematic classification, and controlled retrieval logic. WordPress is not the AI model in this context, but rather the manageable knowledge and publishing system.
What does "around 100 qualified visitors per week" mean?
Matomo measures approximately 135 visits per week during the period under review. "Around 100" is the conservative operator assessment after deducting less relevant and technical accesses.
Responsibility and Effort
Does the Company Resolver identify specific individuals?
No. It evaluates technical company signals at the network level. An organization may appear as a potential visitor; this does not imply the identity of an individual or automatically a sales contact.
What did the development cost?
The case study does not publish confidential project costs. The effort is distributed across strategy, migration, design, content, photography, plugin development, data integration, quality assurance, and ongoing improvement. AI-supported development can significantly accelerate individual prototypes.
