In what types of projects is SSR especially useful?

#1. Online stores (eCommerce, marketplaces)

Why SSR is useful:

• Product pages need to load fast and be indexed by search engines.
• The user needs to see the content right away (especially the product card, price, reviews).
• Previews on social media (OG tags, photos) only work correctly with SSR.

Examples: Zara, ASOS, eBay, Zalando, Amazon, Shopify Storefront (Next.js).

Key effect: Instant first render, better SEO indexing of the catalog and product cards.

#2. Content sites and media (news, blogs, magazines)

Why SSR is useful:

• SEO and load speed are critical for traffic.
• Content often needs updating, but not in real time.

Examples: Medium, Dev.to, Vercel Blog, news portals.

Key effect: Fast content delivery, excellent SEO optimization, support for social sharing.

#3. Corporate sites and landing pages with dynamic content

Why SSR is useful:

• The page needs to look "alive" right away, without waiting for JS.
• There are often forms, personalization ("Hello, Alex"), geolocation, or A/B tests.

Examples: Marketing pages of SaaS services, financial platforms, agency websites.

Key effect: Increases conversion thanks to a fast render and a better first impression.

#4. SaaS platforms and dashboards with public sections

Why SSR is useful:

• The public part (presentation, pricing, demo) needs SEO.
• The internal interface can be CSR, but SSR makes the "entry" instant.

Examples: Notion (partially SSR), Linear, Vercel Dashboard (a hybrid of SSR + CSR).

Key effect: Optimal UX on entry, no "white screen" before hydration.

#5. Services with personalized content

Why SSR is useful:

• Content depends on the user, language, region, or session.
• You can generate ready-made HTML with the right data right away.

Examples: News feeds, recommendation systems, dashboards with user data.

Key effect: Content is relevant and visible immediately, without waiting for the API to load.

#6. Platforms with social or user-generated content

Why SSR is useful:

• Posts, profiles, and comments need to be indexed.
• Links to posts/profiles need to look good in previews (OG tags).

Examples: Twitter (Next.js), Reddit, Product Hunt, LinkedIn (partially SSR).

Key effect: Fast loading of profile and post pages, improved SEO and sharing.

#Where SSR is excessive

SSR isn't needed if:

• the project is a pure SPA/internal interface (admin panel, CRM, analytics),
• there are no SEO requirements,
• content only loads after authorization,
• minimal server latency is critical (for example, a real-time dashboard).

Examples where CSR is better: Firebase Dashboard, Figma Web App, Trello, Slack Web.
