In today's digital age, website performance and Search Engine Optimization (SEO) have become key factors determining the success or failure of online businesses. Users expect pages to load within 2 seconds, while search engines evaluate website quality through complex algorithms. This article will systematically explore the relevant technology stack to help developers build modern websites that are both fast and easily discoverable by search engines.

Technical SEO is the foundational layer of search engine optimization. Key elements include website architecture optimization (clear URL structure, XML sitemap, robots.txt configuration), page rendering strategies (SSR/SSG, dynamic hybrid rendering), and crawl budget management (canonical tags, noindex markers). AEO is the evolutionary direction of SEO, with core strategies including structured Q&A content, Schema.org markup (FAQ/HowTo, etc.), and long-tail keyword optimization to adapt to voice search needs and obtain featured snippets.

Core Web Vitals (LCP, FID/INP, CLS) are important signals for Google ranking. Optimization strategies include server response optimization, resource preloading, JS execution optimization, etc. WCAG accessibility optimization is achieved through semantic HTML, ARIA attributes, keyboard navigation, color contrast, etc., which not only serves users of assistive technologies but also improves search engine understanding.

Playwright can automate SEO health checks (verifying titles, meta tags, structured data, etc.), performance metric monitoring (Core Web Vitals), and accessibility testing (integrated with axe-core). Schema.org structured data is recommended to be implemented using JSON-LD. Common types such as Article and Product can obtain rich media search results and significantly improve click-through rates.

Backlinks are core signals of website authority. Attention should be paid to the authority, relevance, and naturalness of sources. High-quality external links can be attracted through original content (link bait), and opportunities can be identified by analyzing competitors' links. SEO and performance optimization are ongoing processes that need to be integrated into the development workflow, with checklists established for continuous monitoring and iteration to maintain competitiveness.
