What does the flame icon next to certain cards signify in the Topic Research tool?

The flame icon in the Semrush Topic Research tool indicates that a particular subtopic is currently trending. This is a crucial feature for content strategists as it highlights popular and timely subjects, allowing them to create content that resonates with current audience interest and potentially generates higher engagement and traffic. Ignoring trending topics can lead to content that feels dated or irrelevant. The other options are incorrect: the icon does not signify outdated content, content flagged for removal, or irrelevance. Instead, it points to opportunities for timely content creation.
