Published: August 29, 2025 | Author: Ellie Brewster

1. Core Web Vitals

Google’s Core Web Vitals remain a top ranking factor in 2025. Focus on LCP, CLS, and INP to ensure fast loading, visual stability, and quick interactivity. Tools like PageSpeed Insights and Lighthouse are essential for monitoring.

2. Mobile-First Indexing

With mobile-first indexing fully rolled out, your site must deliver the same structured data, meta tags, and high-quality content on both desktop and mobile versions.

3. Site Architecture & Crawl Budget

A clean URL structure and logical hierarchy help Google crawl and index efficiently. Avoid deep nesting and keep important pages within three clicks from the homepage.

4. Schema Markup

Implement structured data for articles, products, and services. Schema increases your chance of rich snippets and higher CTR in SERPs.

5. Indexing & Robots.txt

Use robots.txt and noindex tags wisely. Ensure only valuable pages are indexed, and block duplicate or thin content.

Conclusion

Technical SEO in 2025 is about providing speed, accessibility, and structured clarity. Sites that nail these fundamentals will secure better rankings and user trust.
