Germany is a very attractive market for international businesses -- it has a strong economy and a large, mature and engaged internet audience. However, in order to make the most of the opportunities of this market, providing content and communications in the local German language is essential. Like any language, German has its unique quirks and traits, which can give web marketers a headache when it comes to keywords and website optimisation. One of these quirks are Umlauts, special characters which appear regularly in the language and can impact on German SEO efforts. German SEO specialist Jens Kuhn will help us understand more about them.
