What is website speed optimization in WordPress?
Website speed optimization is the process of reducing the loading time of your web pages on the user’s display. You can achieve speed optimization in WordPress through a combination of techniques and configurations. Here are some common methods to load your website ideally within three seconds:
Advanced hosting: Choose a dedicated WordPress hosting with flexible options and Optimal performance.
Caching mechanism: This mechanism reduces server load by saving a static copy of your webpage (images, HTML, CSS, JavaScript, etc.). So, visitors will see a cached version of your WordPress site when they revisit.
Image optimization: Heavyweight (usually>100KB) images are the main culprits behind slow-loading sites. Optimization reduces file size without compromising quality, using image compression or modern formats like WebP or AVIF.
Content delivery network: It's a global network or service that caches content and asset files such as HTML, CSS, and JavaScript. Visitors see what their closet server shows them by minimizing the loading time.
Code optimization: This method involves reducing file size by omitting unnecessary characters, spaces, and comments from HTML, CSS, and JavaScript files. Plus, it combines multiple files to reduce the number of HTTP requests from browsers.
Lazy loading: This technique delays the loading of nonessential elements, such as images and videos. However, those elements are shown to the user only when they are in the browser viewport.
Database cleanup: Your database can accumulate non-critical data, such as post revisions, spam comments, and unused data. Removing this data can optimize your database and improve WordPress speed.
Theme & plugin managing: Use reliable themes and plugins that are well-coded and lightweight. Well-optimized themes and plugins won't slow down your site.
Maintaining updates: Regularly updating your WordPress core, themes, and plugins can help keep your WordPress site running smoothly.
Core web vitals optimization: Fixing Google’s Core Web Vitals recommendations can improve your site's speed and user experience.
An effective WordPress speed optimization plugin can automate all these tasks for you. In the meantime, you can handle other necessary workloads to grow your business.
