Frequently Asked Questions
How do I improve Sitecore website performance?
Improve Sitecore performance by optimizing JavaScript bundles, images, fonts, data fetching, caching, API routes, database queries, code splitting, and frontend rendering. For headless Sitecore, also evaluate Next.js rendering and caching strategies.
Why is my Sitecore website slow?
A Sitecore website can become slow because of large JavaScript bundles, unoptimized images, inefficient API requests, slow data fetching, excessive client-side rendering, poor caching, database bottlenecks, third-party scripts, or inefficient frontend components.
How can I improve Core Web Vitals for Sitecore?
Focus on LCP, INP, and CLS by optimizing images and fonts, reducing JavaScript, improving server response times, preventing layout shifts, using effective caching, and choosing an appropriate Sitecore rendering and data-fetching strategy.
How do I improve LCP on a Sitecore website?
Improve LCP by optimizing the largest above-the-fold element, especially hero images, reducing render-blocking resources, optimizing fonts, improving TTFB, using caching and CDN delivery, and reducing unnecessary JavaScript.
How do I reduce CLS on Sitecore websites?
Reduce CLS by reserving dimensions for images and media, properly loading fonts, avoiding dynamically inserted content that shifts existing elements, and ensuring components have predictable layouts before content loads.
How can Next.js improve Sitecore performance and SEO?
Next.js can improve Sitecore performance by supporting static generation, incremental static regeneration, server-side rendering, code splitting, optimized images, and efficient data fetching. Pre-rendered HTML can also improve crawlability and page delivery.
What is the best rendering strategy for Sitecore XM Cloud?
The best rendering strategy depends on the page requirements. SSG and ISR are well suited to content that changes infrequently, while SSR is appropriate when content depends on request-time data, personalization, authentication, or other dynamic information.
How does caching improve Sitecore website performance?
Caching reduces repeated computation and data fetching by serving previously generated content or responses. Browser, CDN, application, API, and page caching can reduce server load, improve response times, and help deliver pages faster.
How should images be optimized in Sitecore?
Use appropriately sized images, modern formats such as WebP or AVIF where supported, responsive image delivery, compression, correct dimensions, and suitable lazy-loading strategies. Sitecore's Next.js implementations can also use image optimization components where appropriate.
How can I improve SEO on a Sitecore website?
Improve Sitecore SEO through technically sound HTML, descriptive metadata, canonical URLs, structured data, XML sitemaps, robots controls, accessible content, optimized images, internal linking, fast rendering, Core Web Vitals improvements, and properly rendered indexable HTML.
