Speed is one of the most important parts of the user experience. According to Neil Patel, a one-second delay in page response can result in a 7% reduction in conversions and a 16% decrease in customer satisfaction. Nearly half of consumers expect a web page to load in two seconds or less — and these expectations are getting higher every day.
In addition to the user experience, Google includes speed as a factor when ranking search results. Anyone that relies on organic search traffic should optimize their website's speed in order to avoid penalties and maximize their rankings. Publishers and other content-heavy websites could be experiencing a significant penalty for slow loading times.
Use these checklist items to help identify areas where you can improve the performance of your web application.
- Integrate load tests into your Agile development process using LoadNinja or another tool in order to identify bottlenecks before they become an issue in production.
- Add a content delivery network, or CDN, to distribute cached files across servers around the world to improve speeds for international visitors and users.
- Optimize image sizes to be appropriate for the use case and convert any icons into vector formats to improve resolution and reduce file size.
- Implement server-side caching to reduce the number of requests hitting the database and dramatically improve speed for search queries and other use cases.
- Identify problematic SQL queries or other database commands and refactor them to be more efficient, including N+1 queries generated by ORMs.
- Use prefetching techniques to predict what actions users are about to take and initiate the loading process before a user begins the transaction.
- Implement monitoring solutions to detect 404 and other errors that could be adversely impacting your website’s performance and the user experience.
