Regardless of whether it is a new or an existing project, we will advise you and provide you with comprehensive support in the design, technical requirements, implementation and ongoing support of your Contao project.

Responsive web design

Our focus here is not only on technical functionality on all end devices, but also on UX design to ensure maximum user-friendliness. Whether smartphone, tablet, desktop or web TV, a modern website must be optimally displayed and easy to use everywhere.

Individual web design

There are a large number of solid standard templates for Contao that you can fall back on. However, SINEOS is also happy to work with you to develop individual and sophisticated graphic templates based on your corporate design.

Search engine optimization

We already pay attention to important on-page SEO techniques when designing a web project. Our aim is to provide the customer with the best possible advice and implement this so that your website achieves good visibility, loads quickly and covers essential SEO requirements.

Extension programming

In order to find the perfect solution for you, we will expand the many existing extensions in a meaningful way and reprogram any necessary plug-ins. Of course, we program according to the latest standards so that your website is up to date and secure.

Performance

When programming and building websites, we make sure right from the start that fast loading times can be achieved. This includes responsive images, lazyloading, correct caching settings and code that can be processed with high performance.

Content Creation

We work with you to develop the right content for your website. This starts with support for SEO-optimized texts and continues with recommendations for the right photographer and graphic designer. This guarantees sophisticated and high-quality content for your website.

Marketing Automation

Contao Marketing Suite is a marketing automation tool for Contao. More visitors, more customers, more sales - these are exactly the goals you can achieve with the Contao Marketing Suite. Thanks to A/B tests and conversions, you can identify what your users really want. Everyone is shown the content that corresponds to their own wishes, needs and interests and thus has a better user experience.

GDPR-compliant website

Data protection is an important topic that we take very seriously to ensure that your web portal meets the requirements of the GDPR and is up to date. We also provide tips on how to optimally configure and display the cookie consent banner, for example.

Training and documentation

We will be happy to train you so that you can use your customized website optimally on a day-to-day basis. Training can take place online or on site and the content is tailored to your individual needs. We can also create documentation or training videos on request.

Support for your Contao website

Once a project has been successfully implemented, the work is not over. For a secure and reliable system, SINEOS offers e.g. Service Level Agreements (SLA), so that your Contao instance is protected in the best possible way and the core and extensions are up to date.

The Strengths of the Contao CMS

Contao is an open source CMS, which means that you do not have to pay any license fees and are not dependent on any manufacturer. At the same time, the CMS is characterized by a large and active Contao community. The community, which is based in Germany but has a global presence, is constantly developing new extensions for the Contao core software, which you can then access easily and free of charge. In addition, SINEOS can develop individual and customized extensions for you.

If required, Contao can be expanded to include an online store so that items can be sold directly on the website. Isotope is a powerful e-commerce solution that offers all the important features of a modern store. Connecting to various payment service providers, such as Payone, or automation tools such as Billbee is no problem. Isotope can also be perfectly adapted to individual requirements, as is the case with prowin-bt.net.

You don't need any programming knowledge for Contao! Thanks to the central page structure in the Contao backend, all website content can be found easily and intuitively. Texts can be easily formatted and edited and images can be professionally integrated into the layout - without losing the overview.

Right from the installation, Contao offers many useful modules, such as integrated calendar, news/blog, newsletter and FAQ modules. The Contao core software already enables you to build a professional website. With the numerous available extensions, we can expand and customize your website as desired. Of course, SINEOS can also develop new extensions especially for you, because when it comes to your wishes, we make no compromises. Is your company growing? With Contao, your website can easily grow with you, because Contao is characterized by its high scalability. Thanks to the high flexibility of the CMS, there are no limits to your requirements and wishes.

Especially for websites with many visitors and a clear content and marketing strategy, the Contao Marketing Suite helps to adapt content even better to the needs of your visitors. Depending on user behavior, for example, different content can be displayed or you can carry out A/B tests to see which content converts better. Information on the health status of your web portal is also possible.

Contao supports the creation of responsive web design so that your website looks and functions optimally on all devices. Responsive images ensure that your images are displayed in different sizes depending on the screen size and monitor resolution of your users. This reduces the file size and makes your website more performant. It is also possible to set a focus point so that the optimum image section is always displayed.
