Website Check

Your website is up and running, but is it actually delivering? A website audit reveals where your technology, content, and user experience are falling short—and what you can do about it.

Website Review and Audit

A website audit answers the question many companies ask themselves: Is our website performing as well as it could? We conduct a systematic review and provide an action plan with specific priorities—not just a list of errors.

Clarity Instead of Assumptions

Many companies feel that their website isn’t performing optimally, but don’t know why. Our audit replaces guesswork with facts. You’ll receive a report with specific findings, priorities, and recommendations for action. Whether you implement the measures yourself, with us, or with another agency is entirely up to you. Combined with conversion optimization, you’ll get the most out of your website.

What's slowing down your website?

Slow loading times, missing metadata, broken links, an unclear page structure, or content that misses the mark with your target audience: There are many reasons why a website might underperform. Our audit identifies technical, content-related, and structural weaknesses. Based on this analysis, you’ll know exactly where your website stands and where the greatest improvements can be made.

A website audit covers several areas that work together. We examine each one individually and evaluate how they function in conjunction with one another. We systematically analyze the following areas and document each finding along with specific recommendations for action.

Technisches Audit mit HTTP-Status und Antwortzeit

Technical Audit

We check the server configuration, SSL certificate, crawlability, indexing, redirect chains, and the technical foundation of your CMS. Errors in the technical infrastructure slow everything else down, which is why we start here.

SEO-Audit mit Suchergebnis auf Position 3 und Prüfpunkten

SEO Audit

Metadata, page titles, internal linking, heading structure, duplicate content, and structured data: We review all the factors that influence your visibility in search engines.

Performance-Check mit Core Web Vitals für Desktop und Mobil

Performance Check

Load times, Core Web Vitals, image optimization, caching, and rendering behavior: We measure performance on desktop and mobile and show you where the biggest bottlenecks are.

UX and Usability

User guidance, navigation, page hierarchy, CTA placement, and form design: We evaluate how effectively your website guides visitors to their destination—and where they get lost along the way.

Content-Analyse mit Bewertung einzelner Textpassagen

Content Analysis

We check whether your content is tailored to your target audience, whether it’s SEO-friendly, and whether the text quality is up to par. This includes readability, timeliness, keyword coverage, and whether the content resonates with your visitors.

Mobile Devices and Accessibility

Does your website work just as well on a smartphone as it does on a desktop? Does it meet the WCAG 2.1 criteria? We check both and point out where action is needed.

These companies know how we work

In the technical audit, we examine your website’s infrastructure: server response times, SSL configuration, HTTP status codes, redirect chains, and the robots.txt file. We test whether search engines can find and index all relevant pages. This also includes checking XML sitemaps, canonical tags, and hreflang attributes for multilingual websites. We evaluate the CMS for up-to-date status, security, and extensibility. We document outdated plugins, missing updates, or insecure configurations along with their priority levels. Database performance and the hosting environment are also factored into the evaluation. Incorrect configurations can slow down your entire website, which is why we analyze this area particularly thoroughly. The result is a technical report with prioritized actions that you can forward directly to your development team. If needed, our web development team will handle the implementation.

„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.“
