If it cannot be crawled, it cannot rank
JavaScript frameworks are fine when important content is available to crawlers. Server rendering or static generation for commercial pages is usually the calmer path. Client-only shells that paint content late make debugging painful.
Indexation is a product decision
Thin filters, thank-you pages and staging leftovers should not compete with service pages. Use robots, noindex and parameter handling deliberately. A huge sitemap full of junk is not ambition.
Structured data must match the page
Organization, Service, Breadcrumb and Article markup help when they describe what a visitor can see. Fake review stars and invented addresses are a good way to earn a manual action.
Performance is technical SEO
Slow templates waste crawl time and people. Image formats, font loading and shipping less JavaScript are ranking-adjacent even when they are not a “ranking factor” slide.
