Greeting Salutations
Example Conversation
Insider
Did you check your LCP today?
Outsider
Wait, what’s LCP?
Insider
Largest Contentful Paint—it’s how we measure when the main content appears visibly on screen.
Outsider
Oh, that’s a neat way to see if the site feels fast!
Cultural Context
This greeting quickly signals shared knowledge around critical web performance metrics and invites a check-in on current optimization status.
Inside Jokes
"Just add a CDN"
This joke mocks the oversimplification that adding a Content Delivery Network will magically fix all performance issues, when in fact it's often just one piece of a complex puzzle.
Facts & Sayings
„FCP is king“
Emphasizes the importance of First Contentful Paint as a leading metric to gauge perceived load speed for users.
„Lazy load everything“
A shorthand mantra advocating deferring the loading of non-critical resources until needed to improve performance.
„Don't break the budget“
Refers to adhering to a predefined performance budget (limits on metrics or asset sizes) to maintain a fast site.
„Time to Interactive matters more than load“
Highlights that making a page functional quickly (TTI) is more critical than just initial content showing up.
Unwritten Rules
Always validate performance improvements with real user metrics (RUM) or synthetic tests before declaring victory.
This ensures optimizations actually impact users positively rather than just improving lab metrics.
Share before-and-after audit reports anonymously or with permission at community forums or Slack channels.
Fosters trust and openness while respecting privacy and proprietary concerns.
Avoid premature optimization; target critical bottlenecks first based on data.
Prevents wasting effort on irrelevant tweaks and maintains focus on impactful changes.
Respect browser differences when discussing performance — what works in Chrome may not be identical in Safari or Firefox.
Acknowledging variance avoids misleading conclusions and encourages inclusive solutions.

First Steps & Resources
Get-Started Steps
Time to basics: 2-3 weeks
1
Audit a Real Website
1-2 hoursBasic
Summary: Run a performance audit on a website using browser tools to identify speed bottlenecks and improvement areas.
Details: Begin by selecting a website you own or have permission to analyze. Open your browser’s developer tools (most commonly Chrome DevTools) and use the built-in performance audit feature (such as Lighthouse). Run a full audit, paying attention to metrics like First Contentful Paint, Largest Contentful Paint, and Time to Interactive. Document the results and note the specific issues flagged, such as large images, unused JavaScript, or render-blocking resources. Beginners often feel overwhelmed by the technical jargon or the volume of issues reported. Focus on understanding the most critical metrics and what they mean for user experience. This step is crucial because it grounds your learning in real data and introduces you to the core tools and language of the WPO community. Progress is measured by your ability to interpret audit results and identify at least three actionable areas for improvement.
2
Learn Core Performance Metrics
2-3 hoursBasic
Summary: Study key web performance metrics and understand their impact on user experience and site ranking.
Details: Dedicate time to learning about metrics such as First Contentful Paint (FCP), Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Time to Interactive (TTI). Use reference materials and explainer videos to understand what each metric measures, why it matters, and how it affects real users. Beginners often confuse these metrics or overlook their practical implications. To overcome this, create a simple glossary or flashcards for each metric, and try explaining them in your own words. This foundational knowledge is essential for meaningful participation in the WPO community, as discussions and solutions often revolve around these metrics. Evaluate your progress by being able to describe each metric, its ideal thresholds, and how to measure it using browser tools.
3
Join Performance-Focused Communities
2-4 hoursIntermediate
Summary: Participate in online forums or chat groups dedicated to web performance to observe discussions and ask beginner questions.
Details: Find and join online communities where web performance is the main focus—these might be forums, chat groups, or social media channels. Spend time reading through recent threads, noting the types of questions asked and the resources shared. Introduce yourself and ask a simple, specific question about a performance issue you’ve encountered. Beginners sometimes hesitate to engage due to fear of asking 'basic' questions. Overcome this by reading community guidelines and searching for existing answers before posting. This step is vital for building connections, staying updated on best practices, and learning from real-world scenarios. Progress is measured by your comfort in participating and your ability to contribute or ask informed questions.

4
Implement a Simple Optimization
2-3 hoursIntermediate
Summary: Apply a basic optimization (like image compression or lazy loading) to a test site and measure the impact.
Details: Choose a straightforward optimization technique—such as compressing images, enabling lazy loading, or minifying CSS/JS. Apply this change to a personal or test website. Use browser tools to measure performance before and after the change, focusing on the metrics you’ve learned. Beginners may struggle with implementation details or verifying the impact. To address this, follow step-by-step tutorials and double-check your work with performance audits. This hands-on step is important because it bridges theory and practice, giving you tangible results and confidence. Evaluate your progress by observing measurable improvements in at least one key metric and documenting the process.
5
Review Case Studies and Best Practices
3-4 hoursIntermediate
Summary: Study real-world case studies and best practice guides to understand effective optimization strategies and their outcomes.
Details: Seek out detailed case studies from reputable sources that document how organizations improved their web performance. Focus on the problems faced, the solutions implemented, and the measurable results achieved. Also, review best practice guides to learn about common strategies and pitfalls. Beginners often skim these resources without analyzing the reasoning behind each decision. To get the most value, take notes on what worked, what didn’t, and why. This step is important for contextualizing your learning and understanding how theory is applied at scale. Progress is measured by your ability to summarize key takeaways and relate them to your own projects or audits.

Misconception #1
WPO is just about making websites load faster.
Reality
While load speed is important, WPO encompasses a broad discipline including user experience, resource management, accessibility, and ongoing monitoring.
Misconception #2
More scripts and libraries automatically mean slower sites.
Reality
Well-optimized code and efficient loading techniques can mitigate or even reverse slowdowns caused by additional scripts.
Misconception #3
Using a modern JavaScript framework guarantees good performance.
Reality
Many frameworks add overhead unless carefully optimized, and WPO requires deliberate tuning regardless of tech stack.
