Optimization Checklist
1
Efficient Cache Lifetimes
Set proper cache durations so browsers can store static resources longer, reducing repeat downloads, improving load speed, and lowering overall server requests for returning visitors.
2
Compress Images
Reduce image file sizes using efficient compression and modern formats like WebP to improve load times, decrease bandwidth usage, and deliver faster, smoother performance across all devices.
3
Document Request Latency
Reduce the time it takes for the browser to receive the initial HTML document by improving server response, optimizing hosting, and minimizing delays that impact overall page load speed.
4
Render Blocking Requests
Eliminate or defer scripts and styles that block page rendering so content can load faster, improving perceived performance and allowing users to see and interact with the page sooner.
5
Optimize Font Display
Improve how fonts load by using strategies like font-display swap to ensure text appears quickly, preventing invisible text delays and enhancing readability during initial page load.
6
Optimize Viewport for Mobile
Ensure the viewport is configured correctly so pages scale and render properly on mobile devices, improving readability, layout consistency, and overall usability across different screen sizes.
7
Preload Key Resources
Prioritize important assets by preloading critical resources like fonts, images, or scripts so they are fetched earlier, reducing delays and improving overall page load performance.
8
Reduce Redirects
Minimize unnecessary redirects so users reach the final page faster, reducing extra requests and delays that can slow down loading time and negatively impact overall performance.
9
Minify Code
Remove unnecessary characters, whitespace, and comments from CSS, JavaScript, and HTML files to reduce file sizes, improve load times, and streamline how resources are delivered to users.
10
Reduce Unused JavaScript
Remove or defer unnecessary JavaScript so only essential code loads, reducing file size, improving load speed, and minimizing delays that impact performance and user experience.
11
Avoid Enormous Network Payloads
Reduce the total size of all resources loaded on a page by optimizing images, scripts, and styles to lower bandwidth usage, improve load times, and deliver a more efficient experience.
12
JavaScript Execution Time
Reduce the amount of time the browser spends processing JavaScript by optimizing scripts, removing unnecessary code, and improving efficiency to ensure a faster page performance.
13
Optimize Above-the-Fold Content
Prioritize loading of visible content first so users see key elements immediately, reducing perceived load time and improving user experience while the rest of the page continues loading.
14
Defer Non-Critical JavaScript
Delay loading of non-essential JavaScript until after the main content is visible so critical elements render faster, improving initial load speed and creating a smoother user experience.
15
Reduce Third-Party Scripts
Limit external scripts such as analytics, ads, and widgets to reduce extra requests and processing time, improving load speed, stability, and overall website performance.
16
Optimize Critical CSS
Prioritize the CSS needed for above-the-fold content so visible elements render faster, reducing delays during initial load and improving overall page speed and user experience.
17
LCP Request Discovery
Improve how the browser identifies the largest content element so key images, text, or sections load sooner, helping reduce delays and strengthen overall Largest Contentful Paint performance.
18
Stabilize Layout During Load
Prevent unexpected movement of text, images, and page elements while loading by reserving space properly, improving visual stability and creating a smoother, more reliable browsing experience.
19
Reduce Wordpress Bloat
Remove unnecessary plugins, scripts, and features that add weight to the site, reducing load times, improving performance, and keeping the website lean, efficient, and easier to manage.
20
Minimize Main-Thread Work
Reduce the workload handled by the browser’s main thread by optimizing scripts and tasks, improving responsiveness, speeding up interactions, and delivering a smoother user experience.
21
User Timing Marks and Measures
Track custom performance points within a page to identify delays in loading and execution, helping analyze real user interactions and improve timing, responsiveness, and overall performance.
