How to Write Blog Posts That Rank and Get Read
Ranking content starts with understanding what the searcher needs, then answering it more clearly and completely than anyone else. Here’s the process.

Instead of scattered articles, build connected groups of content around your core topics. Topic clusters help readers navigate and show search engines your depth.
Key takeaways
- A cluster is one broad pillar page linked to several focused supporting articles.
- Build clusters around the topics directly tied to your services.
- Internal links between pillar and supporting pages are what make a cluster work.
- Clusters prevent several of your own pages competing for the same search.
The problem with random posting
Many business blogs are a collection of unrelated posts written whenever inspiration struck. Readers find it hard to explore, and search engines struggle to see what the site is truly expert in. Some posts end up competing with each other for the same searches.
What a topic cluster is
A topic cluster has two parts:
- A pillar page: a comprehensive guide to a broad topic that covers every important aspect at a high level.
- Cluster articles: focused posts that each go deep on one subtopic and link back to the pillar.
For a web design business, the pillar might be “Planning a business website”. Cluster articles could cover choosing a domain, writing website copy, website accessibility, planning a sitemap and preparing for launch.
Why it works
- Readers can move naturally from overview to detail.
- Internal links spread authority across related pages.
- Each page has one clear purpose, which avoids overlap and cannibalisation.
- Gaps in your coverage become obvious and easy to plan.
How to build a cluster
- Choose core topics. Start with the subjects that map directly to your services, usually three to six.
- List the subtopics. Use customer questions, keyword research and competitor content to find specific questions within each topic.
- Map one page per intent. Assign each subtopic to a single article. If two ideas answer the same question, merge them.
- Write the pillar. Cover the topic broadly and link to each cluster article.
- Write the cluster articles. Go deep, and link back to the pillar and to closely related siblings.
- Connect to services. Link from relevant articles to the service page that solves the problem.
Linking guidelines
- Use descriptive anchor text that tells the reader what they will find.
- Link where it genuinely helps the reader, not in a block at the end.
- Update older articles to link to newer ones in the same cluster.
Maintaining clusters
Review each cluster periodically. Refresh the pillar, add articles for new questions, update outdated advice and combine thin posts. A well-maintained cluster keeps growing in value.

Frequently asked questions
How many articles should a cluster have?
Enough to cover the meaningful questions within the topic, often between five and fifteen. Quality and coverage matter more than a specific number.
Can a service page be a pillar?
Sometimes. A detailed service page can act as the hub for its topic, with educational articles linking to it. Many businesses keep a separate guide as the pillar and link both ways.
