What is hreflang?
One of the biggest challenges of international SEO is successfully targeting the right content to the correct region, so that searchers from a particular region are presented with content that is aimed at them. In December 2011, Google introduced a useful solution that can improve regional rankings by offering the use of rel="alternate" hreflang="x" annotations to mark up equivalent webpages targeting different regions or languages. As well as improving rankings, implementing hreflang-x can also help to reduce bounce rates and improve conversions.
Implementing hreflang-x either in HTML or XML format in theory isn't difficult, however, a significant portion of hreflang-x implementations nowadays are still incorrect. Common problems involve incorrect values for the hreflang-x attribute, broken or incorrect references, invalid use of hreflang-x-default and more. If there are problems with a hreflang-x implementation, Google is likely to ignore all included annotations.
Deploying hreflang-x can be a time-consuming task, especially for larger websites with many regional versions. Removing issues and making it error-free will ensure that the effort put into the deployment is producing the desired results. We will review the implementation of hreflang-x on your website, report on errors found and provide recommendations to fix them.
