Pillar Content for WordPress: Boost SEO & Authority in Bangkok, Thailand

If you’re running a business and website in Bangkok, Thailand, you may have noticed the “Mark as Pillar Content” option in WordPress plugins like Rank Math or Yoast SEO. Many businesses ignore this feature, but for those who want to rank higher on Google, especially in competitive markets like Bangkok, pillar content is a must.

Pillar Content

What Is Pillar Content?

Pillar content (sometimes called cornerstone content) is a long, detailed, and authoritative article that covers a broad topic and serves as the main hub for related subtopics. Think of it like a central station where all your topic-related articles (cluster posts) connect. For example:

A digital marketing agency in Bangkok might write a pillar post: “The Ultimate Guide to SEO in Thailand.”

Cluster posts could include:

  • “How Local SEO Works for Thai Businesses”
  • “Top SEO Plugins for WordPress in 2025”
  • “Why Website Design Affects Your SEO Rankings”
    •  

How Does Pillar Content Work?

Here’s how it functions in 4 simple steps:

  • Write a Comprehensive Guide – Your pillar page should fully explain the main topic in 2,000+ words, targeting high-value keywords.
  • Create Cluster Posts – Write smaller, more specific posts about subtopics, each targeting long-tail keywords.
  • Link Everything Together – Add internal links between pillar and cluster posts. SEO plugins like Rank Math help by suggesting pillar pages when adding new content.
  • Keep It Updated – Google rewards fresh, updated content, so revisit your pillar pages regularly.

Why Should You Mark Pillar Content in WordPress?

If you use SEO plugins like Rank Math or Yoast SEO, you may have noticed the option to “tick” pillar or cornerstone content. Here’s why you should always mark it:

  • Better Internal Linking – Plugins prioritize pillar pages in internal link suggestions, helping spread link juice effectively.
  • Improves Google’s Understanding of Site Structure – Search engines easily recognize which pages are most important.
  • Boosts Keyword Rankings – Pillar pages are designed to target high-competition keywords (like “SEO agency Bangkok”), while cluster posts target long-tail keywords.
  • Enhances User Experience – Visitors stay longer because they can easily navigate between related posts, which improves SEO signals.

How Pillar Content Improves SEO in Bangkok, Thailand

For local businesses, including website design companies, SEO agencies, and digital marketing agencies in Thailand, pillar content is a powerful SEO strategy:

  • Builds Topical Authority – Google ranks sites higher when they show expertise on a topic.
  • Improves Local SEO – Adding local keywords like “Bangkok,” “Thailand,” or specific areas like “Sukhumvit” strengthens local search visibility.
  • Increases Organic Traffic – Cluster articles targeting long-tail keywords drive consistent traffic.
  • Boosts Engagement – Interlinked articles keep visitors browsing longer, reducing bounce rates.

Example for a Local Business in Bangkok

Let’s say you run a website design company in Bangkok. Here’s how you can structure pillar content:

Cluster Pages:

  • “Why WordPress Is the Best Platform for Thai Businesses”

Start by identifying your main topics, creating detailed guides, and linking them to cluster posts. Over time, you’ll see better rankings, more organic traffic, and stronger brand credibility.

FAQs

1. What is pillar content in WordPress?

Pillar content is a long-form, comprehensive article that serves as the central hub for a topic on your website. It links to and is linked from related shorter blog posts (cluster content) to create a structured content hierarchy.

Pillar content improves your site’s structure and helps Google understand the relationship between your content pieces. It boosts internal linking, user engagement, and keyword visibility — all of which benefit SEO.

If you’re using an SEO plugin like Rank Math or Yoast, you can simply check the box that says “Mark as Pillar Content” or “Cornerstone Content” in the post settings. This tells the plugin and Google that this post is a key page on your site.

Pillar content is typically longer, more authoritative, and targets broad keywords. Regular blog posts (cluster content) focus on more specific subtopics and support the pillar by linking back to it.

Popular WordPress plugins that support pillar content include:

  • Rank Math SEO
  • Yoast SEO
  • Link Whisper (for smart internal linking)
    These tools help mark, optimize, and connect pillar and cluster content.

Yes. Pillar content with local keywords like “Bangkok web design” or “SEO company in Thailand” can rank higher in local search results, especially when supported by relevant subtopics that target long-tail, location-based queries.

Typically, a good pillar content post is 1,500–3,000 words, covering all major aspects of a topic and providing deep value to the reader. However, quality matters more than word count.
