In short, a topic cluster is a way of asia cell phone number list structuring all the content of a website related to a main or generic topic ( core topic ) , to concentrate the SEO strength of that term on a specific page ( pillar page ) and improve its positioning in search engines.
If the Solar System were a topic cluster , the Sun would be the pillar page , which is the web page with which we want to position the generic topic we have chosen. This pillar page must cover the core topic in an exhaustive and in-depth manner. The different planets orbit around it, which would be the secondary topics or subtopics (posts, videos, etc.). These secondary topics are shorter and must make sense by themselves, but they must also be related to the main topic, so that they serve as support for the pillar page through an effective structure of internal links.
The main topic ( core topic ) around which the topic cluster is organized has to be a generic term, of two or three words, with a high number of searches and with a strategic interest for the brand . On the other hand, the secondary topics must be much more specific ( long tail ), with fewer searches and less competition. The idea is to position a large number of keywords associated with that main topic, an idea that fits with the semantic searches we talked about at the beginning of this post.
