hreflang tag

The hreflang tag is an HTML attribute that helps search engines understand the language and geographic targeting of websites and their content. Es is a crucial factor in SEO localization of multilingual websites.

The hreflang tag tells search engines that certain pages were created specifically for certain languages or regions and should only be served there. For example, an English version of a website might have been created for users in the United States, and a Spanish-language version might have been created for the Spanish-speaking community in the United States. At the same time, our example website has content for European Spanish. Thanks to the hreflang tag, Europeans will also see the appropriate language directories in Spanish. By properly specifying the hreflang tag in the source code, search engines can display the correct version of the website for the correct audience.

Click Through Rate

Click Through Rate (CTR) is one of the most important key performance indicators in SEO. The value measures the number of specific user group clicking on a specific link compared to the total number of users who saw a URL, an ad or an email. A high CTR indicates effective keywords and engaging content that attract the attention of the target audience. It is measured via web analytics tools such as Google Analytics, eTracker, Matomo or other web analytics tools. Especially for those responsible for online marketing, the click through rate offers valuable insights to optimize strategies to increase visibility and improve the user experience.

HTML sitemap

HTML Sitemaps are pages specially developed for users in the form of a tree diagram. Here is a structured list of all important URLs of a website according to hierarchies.

Primarily, HTML Sitemaps are used to help users navigate a website. Especially websites that do not have a clear navigation structure can implement HTML sitemaps. This in turn helps search engines to understand the page context. If the navigation of a website is intuitive and clearly arranged, an HTML sitemap can be dispensed with in the meantime.

If a website needs to catch up in terms of navigation, the HTML sitemap can be linked in the frontend. This temporarily improves the user experience and findability of content.
