Key SEO Benefits of Blogging

By Alexander Ramsey • December 29, 2025 • 84 views

Using a /blog subdirectory generally ranks better than alternatives like a separate subdomain (e.g., blog.example.com) or no blog at all. Search engines treat a subdirectory as a direct part of your main domain, allowing the blog's content to actively boost your site's overall authority and keyword visibility.

Why /blog Ranks Better

  1. Domain Authority Sharing: All the "SEO juice" from your blog posts—including backlinks and social signals—flows directly to your primary domain, improving the rankings of your entire site.
  2. Keyword Expansion: A blog allows you to target long-tail and informational keywords that wouldn't naturally fit on product or service pages.
  3. Topical Authority: Consistently covering a subject in depth signals to search engines that your site is an expert source, leading to higher rankings across related topics.
  4. Internal Linking: You can use blog posts to link to your "money pages" (services or products), helping those core pages rank higher.

When It Can Rank "Worse"

A blog only harms your SEO if it is executed poorly:

  1. Low Quality/Thin Content: Publishing generic or AI-generated "slop" without adding value can lead to poor engagement signals, which may drag down your entire site's ranking.
  2. Duplicate Content: Overusing tags or categories can create duplicate content issues that confuse search engines.
  3. Cannibalization: If a blog post targets the exact same keywords as a core service page, they may compete against each other in search results.

Best Practices for 2025

  1. Nail Search Intent: Modern algorithms prioritize content that fully answers a user's query over simple keyword matching.
  2. Update Regularly: Refreshing old posts with current data tells search engines your information remains reliable.
  3. Optimize for AI Overviews: Valuable, well-structured blog content is often used as a source for Google's AI Overviews at the top of search results.
