Elektrohandel Wandelt GmbH is an online shop for high-quality electrical installation supplies with a comprehensive range and customer-orientated service. More than 100,000 customers express their high level of satisfaction  on rating platforms.
As one of the largest specialist electrical shops in Europe with over 80,000 products, Elektro Wandelt is regarded as a leading company on the German and European market. The company stands for favourable prices, competent advice, friendly service and fast delivery.

The company's aim is to offer customers in the B2C and B2B sectors an efficient and best possible shopping experience. The user-friendliness and speed of the company website is a high priority for the company. High-quality website performance is the key to increasing the conversion rate and user-friendliness as well as a better search engine ranking.

The Elektro Wandelt online shop is based on OXID EE. In order to optimise and improve the webshop performance, our OXID eShop agency implemented additional measures:

  • Cleaning the website of outdated elements in the code, outdated modules, outdated backups and other „useless“ code left behind by previous developers to prevent hacker attacks and website failures.
  • The size of the graphic content has been improved with the Oxid Image Optimiser module for different screen resolutions.
  • Static content is cached by Ngnix, which can provide it (directly) very efficiently.
  • The use of AJAX when filling the shopping basket makes the shopping experience easier for the user. AJAX allows users to add products to the shopping basket immediately without having to reload the same page several times.
  • CSS and JavaScript minimisation to speed up page rendering.
  • Time reduction for HTTP requests.
  • Installation of the new HTTP/2 protocol, which enables multiple data requests to be sent in parallel and stream prioritisation.
  • Development of a  specific module to connect Varnish Cache with Oxid EE.

The user-friendliness of the website for both shop visitors and shop managers has been improved by numerous OXID modules that offer the following:

  • Popup implementation to display the content in a separate popup overlay to emphasise it.
  • Implementation of  special prices.
  • Image upgrade to improve page load time and improve product images, banners and logos in the shop.
  • Adaptation of the website to the new consumer protection laws (in accordance with the GDPR).
  • Creation and management of advertising banners.
  • and much more.

In order to improve the shopping experience and the search on the Elektrohandel Wandelt website, the Doofinder search solution has been expanded and customised.

Now users can search for products much faster thanks to:

  • Customisation of the product layout: display of stock availability, delivery times, ratings, tooltips with information.
  • Connection to voice search.
  • Top products and offers are displayed.
  • You can add products to the shopping basket directly from the Doofinder search window.
