When you start implementing topics on your website, this is possibly easiest done making use of folders. So your topic pillar page will be: example.com/topic/ and your cluster pages may look like example.com/topic/cluster/ (or different for specific product pages, depending on your website’s structure). To keep track of how your traffic changes, making sure you are sharing relevant information and have got it sorted from a technical point of view as well, keep this in mind.
