Only one piece of content can be attached to any single subtopic in a topic cluster. Additionally, each piece of supporting content, such as a blog post or landing page, can only be attached to one topic. There's a limit of 20 subtopics per topic cluster.
If you find you have multiple pieces of content that are optimized for a specific subtopic:
- Analyze the differences between the pieces of content.
- If one of the pieces is more specific or slightly different, explore that difference to see if it warrants another subtopic. Once you decide what that new subtopic is, re-optimize that content to be more unique and target it to the new topic.
- If you find the pieces of content are very similar, we recommend redirecting the lower-performing piece to the higher-performing one.
