About

QDJYLY (qdjyly.com) is a technology blog focused on web development, online classifieds platforms, and search engine optimization (SEO). We turn years of hands-on experience in building sites, deploying systems, and running traffic into practical, ready-to-apply articles for business owners, independent site operators, and web teams.

What we cover

• Business websites – responsive corporate sites, brand pages, and marketing landing pages from planning to launch.
• Classifieds platforms – building, migrating, and extending local-life, jobs, real-estate, and second-hand listing systems.
• SEO – on-page structure, keyword mapping, content strategy, link building, and indexing.
• Apps & mobile – mini-programs, mobile H5, and app adaptation.
• Servers & operations – cloud server selection, DNS, HTTPS/CDN setup, and security maintenance.
• Digital marketing – content, social media, and paid-ads strategy that turns traffic into real growth.

About the domain qdjyly.com

qdjyly.com is now registered and operated by the LUNNA team. The domain was previously used by a network-technology company; after it expired and was released, we re-registered it in 2026. This site has no affiliation with the former registrant; all content is written and maintained independently by the current team.

Editorial principles

• We only publish verified methods and steps, with reproducible configs and examples.
• We don't overstate results; all SEO and traffic figures state their source and method.
• Corrections and contributions are welcome and credited.
