Key Metrics
- Page Load Time: The time it takes for a page to fully render in a user's browser.
- Time to First Byte (TTFB): The time it takes for the browser to receive the first byte of data from the server.
- First Contentful Paint (FCP): The time it takes for the first piece of content to appear on the screen.
- DOMContentLoaded (DOM): The time it takes for the HTML document to be fully parsed and the DOM tree to be constructed.
- Loaded: The time it takes for all resources on the page, including images, scripts, and stylesheets, to be fully loaded.
The Impact on Business Metrics
- Conversion Rates: Slow websites can result in a drop in conversion rates, as users may become impatient and abandon the page.
- Search Engine Rankings: Google and other search engines consider website speed as a ranking factor, meaning faster websites rank higher in search results.
- Brand Reputation: A slow website can damage a company's brand reputation, as users may perceive it as unprofessional or unreliable.
- Customer Satisfaction: A fast website provides a better user experience, leading to increased customer satisfaction.
Common Pitfalls
- Large Image Files: Unnecessarily large images can significantly slow down page load times.
- Excessive JavaScript and CSS: Overusing JavaScript and CSS can increase the file size and complexity of the page.
- Unoptimised HTML: Poorly written HTML code can also contribute to slow page load times.
- Heavy Plugins and Widgets: Using multiple plugins and widgets can add extra weight to the page.
- Inadequate Server Infrastructure: A slow server can limit the speed at which pages are delivered to users.
Tips for Speed Enhancement
- Optimise Images: Compress images without compromising visual quality using tools like TinyPNG or JPEGmini.
- Minify JavaScript and CSS: Remove unnecessary characters and whitespace from JavaScript and CSS files.
- Enable Browser Caching: Leverage browser caching to store frequently accessed resources locally, reducing server load and page load times.
- Use a Content Delivery Network (CDN): Distribute content across multiple servers geographically, reducing the distance between the user and the server.
- Reduce Redirects: Limit the number of redirects on a page, as each redirect adds an additional request to the server.
- Lazy Load Content: Load content only when it is needed, such as scrolling down the page or hovering over an element.
- Improve Server Response Time: Optimise server software, database queries, and hosting infrastructure to reduce TTFB.
- Use a Performance Monitoring Tool: Regularly monitor website performance using tools like Google PageSpeed Insights or GTmetrix to identify areas for improvement.
