The demand for faster and more effective systems is growing as technology develops, and website is no different. The success of your online business depends on a quick and efficient website.
Analyze the site speed, optimize images, detect and remove 404 errors, use prefetching techniques, move the website to an advanced host if necessary to increase site speed, and use correct data types, simple codes, caching, I/O, and efficient algorithms to optimize your code.
Read on to find out how to best implement these activities to optimize code and maintain site speed.
Why is site speed necessary for a website?

Did you know an increase of one-second site speed can boost mobile conversions by 27%?
Online success depends on a fast website, which impacts your conversion rates, repeat customers, and search engine rankings.
And with recent improvements to Google Search ranking, a quick load speed for your website is even more critical as a competitive edge.
Either increase your site speed or risk losing more audience.
Tips for Maintaining Site Speed
Here are a few proven ways to increase your website speed.
1. Check Your Site Speed

Did you know that a standard webpage is less than 3 MB and can take 0-4 seconds to load on average?
Many tools are available to check site speed, such as GTmetrix, WebPage Test, Uptrends, etc.
Things to consider to improve the site speed are as follows:
- Loading performance and duration
- Interactivity (UI/UX)
- Visual Stability (Cross-platform/browser accessibility)
2. Optimize Images
Website graphics are one of the most crucial areas to examine when solving a slow site speed.
Image optimization techniques can significantly reduce load times, from cropping product photos to selecting the appropriate file types for website design elements.
Generally, the optimized website images and graphics should be not more than 300 KB.

Things to consider while optimizing images:
- Select the appropriate image format.
- Select the proper compression ratio and compress images.
- To speed up page loading, swap animated GIFs for video.
- Serve up responsive pictures.
- Serve up images that are the right size.
- Employ WebP images (image format that supports lossy and lossless compression) because they are 26% smaller than JPEG and PNG.
- Use image components on content delivery networks (CDN) to enhance images.
3. Detect 404 Errors
An error code 404 denotes that a “Page is not available.” When the accessed content of a page is no longer available, the hosting will notify browsers or search engines by displaying this notice, the “404 Error.”
404 are dead-ends because they lead the website users nowhere, leading to a loss of audience.

Tips to eradicate 404 errors
- Use plugins and error detection tools to find and fix 404 errors.
- Run the resource through third-party error-detecting programs like Semrush, Sitechecker, Google Webmaster, etc.
- Fix the internal link address if the unavailable pages bring traffic.
- Redirect Google-indexed 404 pages to visible ones using redirection, .htaccess, etc.
4. Use Prefetching Techniques
Prefetching refers to reading and carrying out commands before the user does. The method is quite typical.
It’s a crucial tool for lowering data-network server resolution latency and improving user experience on your site (UX).
Prefetching is enabled by default in current browsers since they anticipate user behavior patterns.

Benefits of prefetching in a website:
- Places data in the cache, making it available for a user to fetch.
- Masks the latency of slower data sources.
- Prefetching can be done dynamically at the runtime.
- This process does not require a compiler.
You can achieve prefetching through the following techniques:
- DNS-prefetching: The procedure requires in advance resolving domains into IP addresses.
- It allows the browser to carry out DNS lookups for links in the background while the user is browsing the current page.
- It mainly focuses on reducing latency, as the user doesn’t have to wait for the lookup to complete.
- Prefetching of links: You can use this kind of prefetching if you are confident that a user will click on a specific link to get to a particular page.
- The technique is beneficial for consistent user journey actions, such as going to the shopping cart page after adding one or more products.
- The browser receives a series of prefetching suggestions from a web page.
- Once the page has fully loaded, it starts silently prefetching the specified documents and putting them in its cache.
- The prefetched documents can be promptly served up from the browser’s cache when the user views them.
- Pre-rendering: This method entails preparing the whole page or at least some of its components.
- Pre-rendering involves downloading content in advance, after which the browser renders it invisibly into a second tab in the background.
- After that, the current content is immediately replaced by the pre-rendered content when the user navigates.
5. Move your website to the optimal host
Choosing the shared server seems compatible with the situation as it is cheaper.
However, you will need a server to manage increased traffic and larger website files once your site gains more frequent visitors.

Why moving to a new host is necessary?
- To achieve high uptime rates.
- It provides access to technical support.
- Fast loading speed.
- Better performance and user experience.
Upgrading to a dedicated server from shared hosting can be beneficial as it smoothens page loading. Moreover, there are frequently other more advantageous options.
Three different hosting configurations are possible:
- Public or shared hosting: This is the quickest and least expensive method for getting your website up. You share the server capacity with other websites hosted using shared hosting.
- Virtual Private Server (VPS) server: VPS uses multiple servers to distribute the material. With a VPS, you may share a server with other users while still having access to a private area where your customizations are independent of different clients.
It will be the best option if your website receives ordinary traffic or your e-commerce site occasionally experiences traffic spikes.
- Dedicated or private server: You can expand your business by hosting your application or services on powerful dedicated servers. Private server hosting offers complete isolation, control, and security for your demanding, mission-critical tasks.
Why is optimizing code necessary for your website?
Optimizing code decreases memory consumption resulting in speed and performance improvements. In fact, it goes hand in hand with site speed-increasing techniques.
Because of increased processing speed, websites with optimized code take less time to execute. It can be highly advantageous, especially for the time- or resource-constrained applications.
Overall, the benefits of optimized code can increase the speed, effectiveness, and efficiency of software applications.
Tips to Optimize Code
Here are a few fundamental guidelines you can follow to optimize your code.
1. Use correct data types
A data type is a data attribute that instructs a computer system how to interpret that data’s value.
Knowing the different sorts of data helps to ensure the expected value to allocate memory wisely.
The secret to improving code performance is in the data types. You can reduce the number of conversions and improve your code’s efficiency by using the appropriate data types.
In most cases, it will be best to have the lowest data type representing the data you are working with.
2. Make your code simple
Keeping code as basic as possible is one of the most crucial optimization techniques. It refers to reducing the code required to produce a desired result.
Often, simpler code is more effective, and simpler code is simpler to debug.
Additionally, it could be simpler to read and comprehend, which is helpful when working on complicated projects with numerous developers.
Tips to make code simpler:
- Break down the problem.
- Start clean.
- Create a flowchart.
- Prepare an algorithm.
- Follow proper coding guidelines.
3. Cache most used data
The main goal of a cache is to improve data retrieval performance by minimizing access to primary storage.
Data caching allows you to save time by preventing the need to recalculate it each time it is required. This rule is especially crucial when writing run code repeatedly, like in a loop.
It helps to ease the execution of data within a short interval.
Moreover, using a profiler will come in handy to enhance the code. As a last step, it will help if you improve your algorithms and data structures.
Here is the list of strategies used to cache data:
- By applying a time to live (TTL) to every one of your cache keys.
- Placing cache next to the database.
- Placing cache between application and database.
- Creating custom output cache providers.
4. Avoid irrelevant I/O
An information processing system called I/O or Input/Output sends and receives data from a network, device, or computer hardware.
Computers cannot communicate with other systems or devices without I/O.
It entails avoiding pointless reads and writes and only doing so when it is vital. You can enhance the performance and efficiency of your code by minimizing needless I/O.
Ensure that your code only reads from and writes to files when it really must adhere to the proper I/O guideline.
Tips to optimize I/O:
- Using virtual partition manager.
- Implementing Quality of Service (QoS).
- Assigning server priority manager.
- Changing the assignment of MP bladers.
5. Use the necessary algorithms
The algorithm is a step-by-step process specifying a series of instructions that must be carried out in a specific order to produce the intended outcome.
Choosing practical algorithms that will finish the work with the least time and resources is helpful for code optimization.
For example, if you needed to sort an enormous array of data. Quick sort is a more effective algorithm since it requires less time to sort the data because it has a lower temporal complexity.
You can use the same algorithm in multiple programming languages because algorithms are typically constructed independently of the underlying languages.
Tips for implementing the algorithm in code optimization:
- Identify the algorithm’s objective.
- Get access to recent and historical data.
- Prepare the appropriate overview.
- Make final adjustments.
- Visualize your outcomes.
- Run your algorithm.
