Your meta descriptions can help you to achieve a good ranking if you take good care of them. The length of your text plays an important role: If your description is too long, Google will change it and not output it. Automatically generated by Google descriptions often summarize the content of your page poorly. In any case, you should maintain the meta data of your pages manually and think about what is stored there. Include your main keyword at the beginning of your text and avoid duplicate content. Formulate your meta description in such a way that your USP can be clearly read by potential visitors to your site. This will give you a competitive advantage.
