Conversion Optimization
Does your website have traffic but not enough results? Conversion optimization turns visitors into customers, clicks into inquiries, and reach into revenue.
Conversion Optimization Agency
Conversion optimization doesn't improve traffic—it improves what happens with that traffic. We analyze where visitors drop off, test alternatives, and optimize your website so that more visitors do what you want them to do: make inquiries, buy, or book.

Where is your website losing visitors?
Most websites lose visitors in areas that aren’t immediately apparent: forms that are too long, unclear CTAs, missing trust elements, or user flows that lead nowhere. We use heat maps, session recordings, and analytics to analyze exactly where this happens. Based on this, we then develop specific actions that make a difference.
Test, Measure, Improve
Conversion optimization isn’t a one-time project—it’s an ongoing process. We develop hypotheses, test them using A/B tests, and measure the results. What works, we keep. What doesn’t work, we discard. That’s how your conversion rate improves step by step.
Conversion optimization encompasses everything that happens between the first click and the desired action. Here are the key levers we use to fine-tune our strategy.
These companies know how we work
Before we optimize, we measure. Using Google Analytics, heatmaps, and session recordings, we analyze your visitors’ behavior: Where do they click, where do they scroll, and where do they leave the site? Based on this, we identify the pages and elements with the greatest potential for optimization. We examine conversion funnels, bounce rates, and time on page for every key page type. We document the results in an audit report with specific recommendations for action and priorities. We set up tracking configurations or correct existing installations to ensure your data is reliable. At the same time, we examine which user groups convert differently and where the greatest losses occur. Without clean data, there can be no sound decisions. This is especially true for sites with paid traffic, where every lost visitor costs real money. A conversion optimization agency without data can only offer advice.

„Working with an agency requires good ideas, cutting-edge technology, and clear budgets with no surprises. But the personal chemistry has to be right, too. With seitenweise, everything was just right. It was really fun.“

„To me, having a strong partner is important. Someone who is “passionate” about their work, who offers well-reasoned professional objections but also accepts and continues to fully support my decisions as a client when I choose a different path. I’ve been working very successfully with seitenweise in this way for many years—both in day-to-day operations and on many large-scale projects.“
