Hello everyone, this is MaoMaoyu.

In today's competitive online environment, Search Engine Optimization (SEO) is crucial for website success. It's not just about content creation, but also about the technical foundation, speed, and user experience of your site. This article will explore how to enhance your website's SEO through correct DNS configuration and Cloudflare optimization.

DNS Configuration: Laying the Foundation for SEO

DNS (Domain Name System) is like the internet's phone book, mapping domain names to server IP addresses. Proper DNS configuration is a cornerstone of SEO.

Key DNS Records

  • A Record: Maps a domain name to an IPv4 address. Example: @ -> 76.76.21.21 (@ usually represents the root domain).
  • CNAME Record: Maps one domain name to another domain name. Example: www -> top4ai.com.

SEO Points for DNS Configuration

  • Unify www and Root Domain: Use CNAME records or 301 redirects to point both www.yourdomain.com and yourdomain.com to the same website, avoiding duplicate content.
  • Preferred Domain: Determine if your preferred domain version is with or without www and redirect the other version to your preferred version. It is recommended to use the version without www.
  • Ensure A Record Points to the Correct Server IP Address.
  • Utilize CDN: Speed up website access and improve security with a CDN.
  • Set Appropriate TTL: Avoid setting TTL values too low or too high to prevent DNS failures or long synchronization times.

Cloudflare Optimization: Accelerating and Securing Your Website (Based on Actual Functionality)

Cloudflare is a powerful CDN and security service provider that can significantly improve your website's performance and security, while also positively impacting SEO.
