1. Matching Your Stack to Your Growth Channel

Choosing the wrong CMS forces expensive re-platforming 18 months later. If your primary acquisition channel is programmatic SEO, interactive calculators, and multi-language directories, a static-first edge architecture or lightweight custom WordPress build gives you complete control over URL trailing slashes, custom JSON-LD graphs, and server headers.

  • Avoid Page-Builder Lock-In: Never build mission-critical B2B sites on heavy DOM-multiplying visual builders that output 15 nested divs per paragraph.
  • Git-Backed Version Control: Store all template code in Git so any deployment can be rolled back in 5 seconds.

Frequently Asked Questions

Does Google rank WordPress higher than Webflow or static HTML?

Google ranks rendered HTML, content quality, Core Web Vitals, and backlink authority—not the underlying CMS. However, static edge HTML and clean custom themes make it much easier to maintain 99/100 technical health.
