Content pillars are the core topics a brand publishes around consistently, chosen because they are relevant to the target audience and aligned with the business's expertise or services. Defining pillars before creating content prevents random publishing and makes it easier to build topical authority in search, maintain a consistent brand voice, and repurpose content efficiently across formats and channels.
How do you identify the right content pillars?
The starting point is the intersection of three things: what the business offers, what the target audience actively searches for or cares about, and where the business has genuine expertise or a credible point of view. A digital marketing agency in Thailand, for example, might build pillars around paid advertising, SEO, analytics, and social media, because those topics directly reflect its services and match what potential clients search for. Pillars should be broad enough to support multiple pieces of content over time, but specific enough to have a clear focus. A pillar labelled 'marketing' is too broad; 'Google Ads for e-commerce' is workable.
How do you build a content pillar structure?
- Define 3 to 5 pillar topics based on your services, audience research, and keyword data. More than five pillars typically leads to unfocused output.
- For each pillar, create a central pillar page: a comprehensive overview article that covers the topic broadly and links out to more specific supporting articles.
- Map out the supporting content for each pillar. These are the specific questions, how-tos, comparisons, and definitions that sit beneath the pillar topic. Each supporting article should link back to the pillar page and to other related supporting articles.
- Use keyword research to prioritise which supporting articles to produce first, focusing on topics with clear search intent and manageable competition.
- Review pillar performance periodically using GA4 and Google Search Console to identify which articles are generating organic traffic and where gaps remain.
How many content pillars should you have?
Most businesses benefit from three to five well-developed pillars rather than a larger number of partially built ones. A pillar that has ten or more supporting articles with strong internal linking will typically outperform a broader set of pillars with only one or two supporting articles each. The goal is depth within each topic, not breadth across many. Publishing schedule matters too: a small team producing content regularly within a focused pillar structure will build topical authority faster than a larger team producing occasional content across unrelated topics.
How do content pillars help with SEO?
Search engines interpret internal links as signals of relevance and authority. A well-structured pillar cluster, where the pillar page and supporting articles link to each other consistently, tells Google that the site has comprehensive coverage of a topic. This tends to improve the ranking potential of all articles within the cluster, not just the individual page. At Phoenix Media, we use the pillar and cluster model as the backbone of content strategy for clients building organic search presence, particularly in competitive categories where ranking on service pages alone is difficult.
