Website Maintenance

A website is not a project with an end date. Without ongoing maintenance, it loses security, speed, and effectiveness.

Website Maintenance and Support

Websites become outdated quickly. New updates, security patches, and browser versions are released every week. Without regular maintenance, a website gradually loses speed, security, and visibility. We make sure that doesn't happen.

Updates and Security,
Before It's Too Late

Performance that
impresses visitors and search engines

A team that knows your website,
not just the contract

Prevention Rather Than Reaction

Our maintenance is proactive, not reactive. We don’t wait until something breaks; instead, we regularly check to make sure everything is running smoothly. We test updates in a staging environment before they go live. Monitoring systems flag anomalies before they turn into problems. Whether it’s WordPress, TYPO3, or another CMS: We know the systems your website is built on and keep them technically up to date.

What Happens Without Maintenance

All it takes is one outdated plugin to make a website vulnerable. Security vulnerabilities, slow loading times, and display errors are not exceptions—they’re the norm for neglected websites. Often, companies don’t realize this until it’s too late: a hack, a drop in search rankings, or visitors bouncing off the site. Professional web development doesn’t end with the launch. A website needs ongoing technical maintenance, just like any other infrastructure in your company.

Professional website maintenance involves more than just occasional updates. From security patches to backup strategies to content management: every component helps ensure that your website functions reliably and delivers results over the long term. We take care of every aspect so that your website not only runs smoothly but also grows.

Updates and Patches

CMS updates, plugin updates, theme updates, and security patches: We keep your website up to date technically. Every update is tested in a staging environment before it goes live. This ensures that functionality and design remain intact.

Security and Malware Protection

Firewall configuration, malware scans, and login protection safeguard your website against attacks. We monitor for suspicious activity and respond immediately if a threat is detected.

Backup and Recovery

Daily backups, stored off-site and restorable at any time. If something goes wrong, we can restore your website to its most recent version within a few hours—without any data loss or extended downtime.

Performance Optimization

Fast loading times aren't a one-time achievement—they require ongoing maintenance. We optimize images, caching, and database queries, and keep an eye on the Core Web Vitals. This ensures your website stays fast—not just loads quickly.

Content Maintenance

Update text, create new pages, replace images, or customize forms: We handle the ongoing maintenance of your content. You send us the changes, and we implement them, ensuring they’re properly formatted and SEO-friendly.

Monitoring and Reporting

Uptime monitoring, performance checks, and monthly reports show you how your website is performing. No surprises, no black box. You always know what we're doing and why.

WordPress Maintenance

WordPress receives several core updates each year, as well as ongoing updates for plugins and themes. We first install them in a staging environment, test the site, and only then deploy them to production. You won’t notice anything about the maintenance except for the report.

These companies know how we work

A secure website requires more than just an SSL certificate. We rely on multiple layers of protection: a firewall, malware scanners, hardened login areas, two-factor authentication, and regular security audits. Attack patterns are constantly changing, so we continuously adapt our security measures. We also check the server configuration: PHP versions, file permissions, and HTTP security headers are part of our standard procedure. The same principles apply to TYPO3 and other CMS systems, with system-specific measures. We automatically monitor suspicious activity and respond immediately if a pattern is detected. Brute-force attacks, spam injections, and known exploit attempts are blocked on the spot. In addition, we log all security-related events and evaluate them regularly. If an attack does get through, our backup and recovery processes kick in: we restore your website and patch the vulnerability. For us, website maintenance and support means having someone keep an eye on things before anything goes down.

Website Audit

We start by conducting an assessment. We review your website for technical vulnerabilities, outdated components, security flaws, and performance issues. The audit provides a clear list of priorities: what needs to be addressed immediately and what can be improved over the long term.

Setup and Configuration

Based on the audit, we set up the maintenance infrastructure: staging environment, backup system, monitoring tools, and security measures. Everything is documented and tailored to your website—not as a standard package, but to meet your actual needs. We also configure the communication channels so you know how to reach us and how to receive updates.

Ongoing Support

From now on, we’ll handle regular maintenance: updates, security scans, backups, and performance checks. We’ll implement content changes, and we’ll plan technical adjustments together. You’ll have a dedicated point of contact who knows your website and can help you directly with any questions.

Monthly Reporting

Every month, you’ll receive a report detailing the updates we’ve implemented, uptime, performance metrics, security status, and open recommendations. It’s transparent and easy to understand, even for decision-makers without a technical background. The report also shows you what actions are planned and what we’re working on. That way, you’ll always know where you stand.

Further Development

Maintenance doesn’t mean downtime. We identify areas for improvement and suggest optimizations: new features, better user guidance, or technical upgrades. This way, your website not only stays up to date but also gets better over time.

We keep your website up and running.

seitenweise is a digital agency based in Bielefeld, founded in 1999. With over 500 projects and more than 100 clients, we know that launching a website is just the beginning. We combine maintenance with web development and strategy, because technical support without an understanding of the big picture is only half the job. With us, the same team that built the website handles its ongoing support. No handoff to an external help desk, no starting from scratch with every call. That means: quick solutions, continuity, and a genuine partnership instead of mere transactions.
