It's true that technical factors like Core Web Vitals and mobile-friendliness are becoming more and more important this year. But in the end, it still comes back to quality content to keep readers engaged for a long time.

In 2025, top on-page SEO factors include optimizing title tags and meta descriptions with relevant keywords, using clean URL structures, and maintaining fast page speed. High-quality, original content that satisfies user intent remains crucial. Also, focus on mobile responsiveness, proper header tag usage (H1–H6), internal linking, and image alt texts. Structured data (schema markup) and user engagement metrics like time on page and bounce rate are gaining more SEO weight.
