Top 10 Free WordPress Themes for Tech Bloggers (2025): Speed, SEO & AdSense-Ready

Why Theme Choice Matters for Tech Blogs

Tech audiences demand:

Sub-second load times (especially for image/video-heavy reviews)
Flawless code snippet rendering (CSS/JS compatibility)
Schema markup for tutorials, product comparisons, and “how-to” guides
AdSense-friendly layouts with clear content/ad separation
Dark mode support for developer-focused content

Fail these, and you lose credibility and revenue.
