Reputation Management for Healthcare Facilities

A medical practice treats dozens of satisfied patients every day. Wait times are kept to a minimum, the staff is friendly, medical care is provided efficiently, and the results speak for themselves. And yet, the practice’s Google Business Profile shows an average rating of 3.8 out of 5. The reason: the satisfied majority of patients remain silent, but the one person who waited 40 minutes does not.

Review management for healthcare facilities operates under different rules than in other industries. The special protection of personal health data severely limits what can be responded to, and legal frameworks dictate how proactively reviews can be solicited. And since May 2026, Google has even been publicly displaying how often a facility has had reviews removed due to defamation. Those who know how to navigate the specific restrictions in the healthcare sector and learn to work with them rather than against them can still actively shape their facility’s review profile.

Grounding Pages for Greater Visibility in AI Search

There are companies that have been producing high-quality content for years and achieving solid search engine rankings as a result. And yet, they simply don’t appear in the responses from ChatGPT, Perplexity, and other LLMs. Not because their content is poor, but because AI systems simply can’t make sense of it. Today, anyone who writes for humans must also ensure that machines understand who or what is behind that content. This is exactly where grounding pages come in.

E-E-A-T in a medical context

Fifteen years of clinical experience. A medical specialty certification earned after a long training process. Daily interactions with numerous patients, regular continuing education, and perhaps even publications in professional journals. To everyone in the practice, this doctor’s expertise is obvious. But for search engines and AI tools, it simply doesn’t exist if it isn’t documented digitally anywhere.

This is precisely the core problem for many medical institutions in the digital space. It is not a lack of expertise, but a lack of documentation of that expertise. E-E-A-T, Google’s evaluation framework for content quality assurance, offers a concrete way to change this. Those who understand the four pillars and strategically address them create digital visibility based on genuine substance—and thus ensure long-term success.

Expert Interview: Healthcare & AI Compliance

Max-Raphael Feibel met Daniel Kleiboldt during a discussion about the EU AI Act and immediately realized that he thinks differently from most people who write about compliance. No alarmism, no abstract references to legal provisions. Instead, concrete architectural decisions and a thesis that immediately piqued Max’s interest as a healthcare marketing specialist: that legally compliant AI systems not only prevent liability but actively strengthen patient trust. And in healthcare marketing, trust is the currency with the highest ROI.

Improve Meta Ads Performance

Are your Meta campaigns not delivering the expected results? Costs are rising while conversions are falling, or your ads are suddenly barely being shown. Performance issues with Meta Ads usually have specific, fixable causes. The key is to take a structured approach and focus your optimization efforts on the right areas. In this article, we’ll show you the seven most common pitfalls and how to overcome them.

Partner & Söhne a Google Premium Partner for 2026

There are many certifications in the agency market. Some can be earned after completing an online course, while others can simply be purchased for a fee. Google Premium Partner status doesn’t work that way. It can neither be bought nor quickly attained, which makes it one of the most credible accolades a Google Ads agency can hold. That’s why we’re thrilled that Partner & Söhne achieved Partner & Söhne status in 2026. It confirms what we’ve understood for years as the foundation of our work: thinking sustainably, working for the long term, and delivering results that stand the test of time.

The Importance of Personal Branding for Businesses

Brands are increasingly losing control over the context in which they appear. An elaborately designed website, well-thought-out navigation, consistent corporate identity. All of this loses visibility when content appears fragmented in AI responses, search results, or feeds. The brand framework that was supposed to classify statements is disappearing.

In AI-generated responses in particular, content is taken out of its original context and reassembled. Large language models (LLMs) summarize information from various sources and present individual statements without the surrounding website. But what remains when the brand framework is missing? The source. And sources with recognizable authors are currently considered more credible by these systems than abstract organizations.

Healthcare Marketing in a Highly Regulated Market

An online store for sports shoes launches a new campaign. Flashy banners advertise a 20 percent discount, a countdown timer shows "Only 3 left in stock," and retargeting ads follow interested customers across all channels. Meanwhile, a dental practice is planning its marketing strategy for the coming season. No discounts possible, no dramatic scarcity messages allowed, every word legally reviewed. The difference could hardly be greater.

Anyone who works in healthcare marketing is familiar with this discrepancy from their daily business. The rules of the game are fundamentally different from those in classic e-commerce or B2B marketing. Strict legal requirements, increased data protection requirements, ethical boundaries, and a completely different trust dynamic shape every single decision. These special features make healthcare marketing one of the most demanding disciplines in digital marketing—and require specialized know-how that goes far beyond classic performance marketing.

Prompt Monitoring: How to track your visibility in AI search

People talk to AI systems differently than they search on Google. "Project management tool remote team" becomes "I'm looking for a solution for project management in a distributed team of ten people." This natural language fundamentally changes how content is found and, therefore, how you need to measure whether your content is even discoverable. Traditional keyword rankings are ineffective when the majority of people are no longer searching for keywords. So how can you track your brand's performance in AI tool search results? Prompt Monitoring provides the answer to this question. It systematically records when and how AI systems talk about your company, which sources they use, and how you are positioned compared to your competitors. In this article, you will learn how prompt monitoring works, why it differs fundamentally from classic keyword tracking, and what specific options for action it offers.

Which KPIs are truly relevant in B2B lead generation?

You invest your budget in ads, build content, and generate hundreds of leads per month. The conversion rate is steadily increasing. Your marketing dashboard looks good. Nevertheless, sales remain below expectations. The problem is not a lack of marketing activity, but rather incorrect success indicators. Many B2B companies focus on metrics that look impressive but say little about actual business success. The key KPIs are not at the beginning of the funnel, but where leads actually turn into paying customers. This article shows you which metrics really matter and how you can use them for strategic decisions.
