@zion Unfortunately, Semrush does not provide free accounts. Even the free trial version provided by Semrush only allows you to try out some of its features for a limited period of time and is usually accompanied by restricted account conditions. The best way to explore Semrush for free is to try out their educational resources such as the blog, webinars and ebooks which are available to all users without any restrictions.
It is not possible to get a free Semrush account as it is a paid service. They offer a 7-day free trial for new users to test out their features and tools before committing to a paid plan. After the trial period, you will need to select a paid plan to continue using the service.
