What SEO Really Is

SEO = optimizing website content and structure to rank higher in search engine results (Baidu/Google/Bing). Higher rank = more clicks = FREE traffic (vs SEM where each click costs money). SEO takes 3-6 months to show results but once ranked, traffic continues without per-click cost. SEM gives instant results but stops when budget stops. Best strategy: both simultaneously.

Keyword Strategy

Keywords are SEO core. Process: mine all terms target customers might search (Baidu Index, Google Keyword Planner, 5118, Aizhan). Filter by: search volume (must have people searching), relevance (must match business), competition (too hard unrealistic short-term). Distribute selected keywords across pages (each page targets 1-2 core keywords).

An accounting agency in 益阳 Ziyang District optimized around: 益阳 agent bookkeeping (320 monthly searches), 益阳 company registration (480), 益阳 tax filing (180), 益阳 financial consulting (120). Six months later all four ranked top 3 on Baidu first page. Monthly 180 organic visitors converting to 25-35 valid inquiries. At 200 RMB per inquiry value saves 5,000-7,000 RMB monthly in ad spend.

Content Optimization

Search engines love: original (not copied), in-depth (not superficial fluff), problem-solving (not self-promotional), regularly updated content. Each core keyword gets one 800+ word deep article. Title contains keyword naturally. First 200 words include keyword. Use H2/H3 subheadings. Add internal links between related pages. At least 1-2 quality articles weekly. Persist 3+ months to see results.

Technical SEO

Beyond content: page speed under 3 seconds (test with PageSpeed Insights). Mobile-friendly responsive design. HTTPS enabled (Let's Encrypt free). Clear site structure with logical navigation. Clean URL structure (/products/abc.html better than /item?id=123). Submit sitemap.xml to Baidu/Google. Proper robots.txt. Internal linking strategy.

Link Building

External links signal authority. Quality over quantity - one authoritative link > 100 spam links. Methods: publish valuable articles on industry media with your link, partner/supplier link exchanges (moderate), answer questions on Baidu Zhidao/Zhihu/Tieba with subtle links, create original data/reports/tools others cite naturally.
