Layer 1: can the page be accessed reliably?
Crawlers encounter HTTP responses first. Indexable pages should return a stable 200, legacy pages should use one-to-one permanent redirects, and missing pages should return a real 404. Language negotiation must not override explicit Chinese or English URLs.
Robots rules, login walls, script-only rendering, timeouts, and cached errors can hide important content. A normal browser view does not prove that a crawler receives the same page.
Layer 2: are the company and products explained clearly?
Pages should consistently identify the company, services, products, technologies, industries, locations, and contact information. Organization and Service schema can support this only when the facts are visible in the page.
A claim such as “leader in intelligent solutions” does not connect the brand to a real task unless products, use cases, and evidence are also explicit.
Layer 3: does each page answer one clear question?
Service pages explain the problem and deliverable; product pages explain capabilities, specifications, fit, and limitations; use-case pages explain the task, selection logic, and integration; guides carry complex reusable knowledge.
Answer on the first screen. Do not make users and machines pass several screens of brand narrative before finding the subject. FAQs can extend related questions, while complex questions should become guides.
Layer 4: do important claims have reliable sources?
Evidence may include product specifications, public documents, certifications, dated cases, technical explanations, or an accountable contact. Outcome figures need a defined time range and measurement method.
Schema can describe what a page says. It cannot convert an unsupported claim into a fact.
Layer 5: do related pages link to each other?
Internal links explain product-to-use-case, case-to-service, and FAQ-to-guide relationships. Link text should describe the destination, and related content should be reachable directly rather than routing everything through the homepage.
Layer 6: are Chinese and English pages matched correctly?
Chinese and English need stable URLs, self canonicals, and real reciprocal hreflang. Do not declare a translation that does not exist. A language switch should keep the user on the corresponding subject page.
Layer 7: is the website fast and stable?
Oversized images, blocking scripts, layout shifts, and incorrect caches affect users and crawl efficiency. Static corporate content can use aggressive CDN caching when releases include refresh, verification, and rollback.
Quick checklist
- Does important body content remain when JavaScript is disabled?
- Do the first two paragraphs answer the core question?
- Do material facts have sources, dates, and boundaries?
- Do canonical, hreflang, sitemap, and links point to final URLs?
- Does schema contain only visible facts?
- Can a mobile user load the page and submit a lead reliably?
