1. Crawl and index: Let search engines see you first

• Robots and Sitemaps : Ensure robots.txt is correctly blocking traffic, submit sitemap.xml to Search Console, and noindex duplicate pages. For best practices, refer to Google Search Central 's Crawl and Index Guide.

• Canonical : Parameter pages, pagination, and country/currency versions use rel="canonical" to indicate the main version, reducing duplicate content and distributing weight.

• Logs and crawl budget : Regularly check server logs and Search Console's "crawl statistics" and prioritize budget for high-value columns and product pages.

2. Site Information Architecture: Using Structure to Reduce Crawling Costs

• Three-layer structure : Home page → Category/Industry page → Product/Solution page, click depth ≤ 3.

• Internal links : Column navigation, breadcrumbs, and related product/article recommendations form topic clusters, allowing search engines to understand the context along the links.

• Semantic HTML : Using tags such as <header><main><article><section><nav> helps search engines parse the main and secondary content of a page. For practices and principles, please refer to the W3C semantic specifications.

3. Structured Data: Let Algorithms “Understand” Your Business

• Schema annotation : Product pages use Product/Offer/Review , Case studies and customer stories use Article , FAQs use FAQPage , and breadcrumbs use BreadcrumbList , all using JSON-LD. See Schema.org for the full vocabulary.

• Rich result opportunities : FAQ/breadcrumbs/product prices and inventory can be enhanced in search results to increase CTR (click-through rate).

• Data consistency : The visible information on the page must be consistent with the structured data to avoid misleading and causing a reduction in authority.

4. Content and EEAT: Writing for Buyers and Algorithms

• Buyer Intent Mapping : Organize content around "Problem → Solution → Evidence → Action"; each page has a clear H1 (including core words) and H2/H3 to take on long-tail questions.

• Verifiable evidence : parameter tables, laboratory/test reports, delivery SLAs, after-sales policies, and third-party certification numbers make "professionalism and credibility" quantifiable.

• Continuous updates : Establish an "industry vocabulary - editing schedule - update feedback" mechanism, refer to Google Search Central 's originality and practicality suggestions to maintain content freshness and usability.

5. Page Experience and Speed: A Good Experience is Also a Ranking Signal

• Core Web Vitals : LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1; use static/edge rendering, CDN, WebP/AVIF images, and defer non-critical scripts. Metrics and optimization paths are based on Google Search Central .

• Accessibility and mobile : Contrast, focusable elements, and form usability follow W3C WCAG ; on mobile, prioritize displaying value and the primary CTA on the first screen.

6. Multilingualism and Localization: The Right Way to Market

• hreflang annotation : Create corresponding URLs for different languages/regions and point to each other; localize prices, units of measurement, and time zones.

• URL and meta information localization : Title, description and Schema are translated simultaneously to avoid mismatches such as "English page with Chinese title".

• Content differentiation : The same topic is rewritten to address market pain points rather than being translated literally, reducing duplication risks and increasing relevance.

7. Pre- and Post-Launch Checklist (You Can Follow It Directly)
