Remember, web performance optimization is not a destination but a continuous journey of improvements and adjustments.

1. Choose a Solid Hosting Solution

You should choose a web hosting that is not only stable but also efficient and agile. Selecting an appropriate hosting provider is crucial in deciding the speed of your web pages. Here we share some aspects to consider:

• Loading speed is a determining factor for SEO and user experience. To achieve this, ensure the hosting service is running on updated software and hardware (RAM, SSD, etc.) that meets your needs.
• Good hosting should guarantee high availability, ensuring that your site is operational without interruptions.
• Choosing an option with scalability will allow you to grow without tedious migrations.
• Consider security a vital aspect of protecting your data and your users. Make sure it uses the latest software to avoid vulnerabilities and has layers of protection, in addition to periodic backups.

Remember, opting for a cheap alternative could be more expensive in the long run if it doesn't meet these essential features. Therefore, take the time to evaluate and select the best hosting solution that supports your goals.

2. Image Optimization for a Lightweight Site

In web performance, it is crucial to consider image compression. This process not only speeds up the loading of your pages but also enhances the user experience. By reducing the size of your graphics, bandwidth demand decreases, leading to a faster and more efficient site. Below, we detail how you can optimize your images:

1. Select appropriate formats: JPEG for photos, PNG for transparent graphics, and SVG for vector illustrations. Remember to use the new, even lighter formats, such as the WEBP format.
2. Use compression tools that maintain visual quality while minimizing file weight.
3. It implements lazy loading techniques, where images are only loaded when necessary.
4. Consider using CDN services that store and distribute your optimized images globally.

Remember, effectively managing your visual resources is a pillar in optimizing any website. So, before uploading a new image, ensure it is properly compressed so you do not sacrifice speed for aesthetics.

3. Use Lighter Themes

It is a fact that the lightness and simplicity of a theme can positively influence the loading speed of your website. Here are some suggestions to make your digital platform faster and more effective:

• Opt for sober and minimalist designs that require fewer resources to load.
• Choose plugins or modules that provide functionality without overloading the system.

By integrating these elements lightly, you will not only optimize speed but also offer a smoother and more pleasant user experience. Remember, an agile and well-structured site is synonymous with efficiency and satisfaction for your visitors. Don't get carried away with the most striking themes without first checking that they are optimized, and do not overload server and user resources without justification.

4. Choice of Plugins If You’re Using WordPress

WordPress relies on a system of plugins to extend and improve its functionalities. This should be taken seriously since the performance and speed of your website depend on it. When choosing plugins, consider the following aspects:

• Compatibility:  Make sure the plugin works harmoniously with your version of WordPress or your CMS and other installed plugins.
• Weight and load:  Choose those that do not overload your website. Look for efficiency instead of extra features.
• Updates and support:  Opt for plugins with a history of continuous improvements and an active community behind them.
• Ratings:  Consider the opinions of other users to anticipate possible complications.

Remember that less is more: too many plugins can slow down your site. Therefore, select only those essential for your website. In addition, you can consider more efficient alternatives to the plugins you currently have installed since there are enormous plugins for which you may only need a minimal part of what they offer.

5. Minimize the Impact of JavaScript and CSS

Another point to highlight may be to minimize the weight of JavaScript and CSS style sheets. Although essential for creating dynamic and aesthetically pleasing sites, these technologies can also become a heavy burden that slows down the user experience.

Strategies to Optimize JavaScript and CSS

1. Employ minification involves removing all unnecessary characters from your code files without altering their functionality. This would include spaces, line breaks, comment blocks, and even changing variable names to shorter ones, even just one letter.
2. Consider aggregation, combining multiple scripts or styles into a single file to reduce HTTP requests.
3. Use lazy loading to load scripts only when needed rather than during the initial page load.
4. Optimizes rendering criticality by prioritizing styles and scripts critical to the initially visible content.

Implementing these tactics will improve the loading speed of your pages and offer better interaction for your visitors.

6. Use a CDN

Consider using a Content Delivery Network (CDN) to improve your website's performance. A CDN allows copies of your content to be stored on multiple servers in different geographical locations, facilitating faster access for users by reducing the distance of information.
Benefits of using a CDN

• Speed ​​of loading: Your visitors will experience a decrease in waiting time when accessing your site.
• Scalability: A CDN can manage the load in the event of an unexpected increase in traffic, maintaining optimal performance.
• Resilience: Distributing data reduces the risk of downtime due to overload or DDoS attacks.
• Improved SEO: Search engines prioritize websites with fast loading times, which could boost your visibility.

Using a Content Delivery Network (CDN) can help improve your website's performance even if your internet speed is fast but pages load slow, by reducing the distance of information travel.

7. Use Prefetching to Enhance Your Page Loading Speed

Prefetching consists of preloading certain elements or pages that a user might need in the future. This strategic anticipation significantly improves the browsing experience by reducing waiting times when loading content.

To effectively implement prefetching, consider the following steps:

1. Identify the resources that your users will most likely request next.
2. Use link tags with the  rel=» prefetch» ​​attribute in your site's HTML code.
3. Take advantage of HTTP headers to tell browsers to prefetch in the background.
4. Monitor your audience's behavior to adjust and refine the selection of preloaded resources.

Remember that the key is to be discerning and not overuse this technique. Abusing this method can have the opposite effect and slow down your pages. Be selective and consider prefetching as an ally in your Web Performance Optimization strategy.

8. Deactivate Unused Plugins

This action benefits your website's performance and contributes to its security. Additional extensions are expected to accumulate during web development, but keeping them active unnecessarily can slow down your page and expose it to vulnerabilities. Furthermore, these plugins often must be updated to the latest versions, increasing the risk.

Eliminating or deactivating superfluous additions is a recommended practice that provides clear benefits:

• Resource optimization: Inactive plugins consume space and potentially slow down site loading.
• Risk Reduction: Every plugin is a potential gateway for security threats.
• Faster updates: Fewer items to update means a more straightforward maintenance process.

However, before proceeding, it is prudent to conduct a thorough review to ensure that the plugins to be deactivated are not essential for your site's functioning. Remember, the goal is to achieve a balance between functionality and efficiency.

9. Implement Gzip Compression

You should always consider implementing  Gzip, a compression method that reduces the size of files transmitted from your server to users' browsers. This speeds up page loading and improves user experience by minimizing wait time. Now, how can you apply this technique to your website?

• First, check if your server supports  Gzip. Most hosting services already have this feature.
• Subsequently, configure your server to apply automatic compression to files that can be compressed.
• Properly selecting the types of content that will benefit most from compression, such as style sheets (CSS), programming scripts (JavaScript), and documents in HTML format, is essential.

Remember that not all files are compressed equally efficiently; For example, images and videos are usually already compressed and do not require Gzip. Implementing Gzip is an essential step in optimizing your site, which improves loading speed and can contribute to a better position in search results, where speed is a determining factor.

10. Block Hotlinking

You should avoid directly linking your multimedia resources to external sites so others cannot exploit them. This practice, known as hotlinking, can significantly reduce your website's loading speed, thus affecting web performance optimization. By preventing other sites from using your images or videos directly from your server, you conserve bandwidth and promote a smoother, more satisfying user experience.

• Analyze your .htaccess files to set appropriate restrictions.
• Use add-ons or security plugins that offer this functionality with ease.
• Check your CDN settings to ensure it includes hotlinking protection.

With these measures, not only will your site be faster, but you will also protect your content from unauthorized use.

11. Implement Web Caching

Implementing cache systems allows frequently requested content to be stored for rapid retrieval, ensuring that users do not encounter errors like 'couldn't preview file there was a problem loading more pages.

Web Caching acts as an ephemeral repository for a site's data, allowing content to be delivered more quickly during subsequent visits and reducing occurrences of errors like 'there’s an issue and the page could not be loaded.

Additionally, caching decreases the amount of data that must be transferred between the servers and relieves the workload on your hosting infrastructure, translating into substantial resource savings and improved website stability.

To take advantage of this technique, consider the following steps:

1. Identify which resources can be cached without affecting the recency of the content.
2. Configure caching policies on your web server or use third-party tools specialized in this function.
3. Monitor the effectiveness of the implemented cache and adjust as necessary to balance performance and content freshness.

Web caching is not a single solution that applies to all scenarios equally. It is imperative to adapt the settings to your website's specific needs to maximize its benefits.

12. Optimization with PHP OPcache

Beyond the traditional cache, keep an eye on how  PHP OPcache optimizes the loading of your web applications based on this language, such as WordPress. Crucial for performance optimization, this module preloads and stores the compiled code of your PHP scripts in memory. In this way, the redundant effort of interpreting the duplicate files in each request is avoided, speeding up the server response significantly.

Implementing PHP OPcache is synonymous with increasing efficiency. By activating this mechanism, you will see notable improvements in the  loading speed  and overall performance of your site:

1. Reduction of response time by avoiding repetitive code compilation.
2. Decrease in the use of server resources, which translates into a greater capacity to handle concurrent traffic.

Fluidity and agility in navigation improve the user experience and favor the perception of the quality of your digital platform.

13. Eliminate HTTP Requests Without Functional Value

Consider removing HTTP requests that do not provide meaningful functionality to your site. This process contributes to a better user experience and optimizes loading times, a determining factor in visitor retention and overall site efficiency. Reducing these redundant or unnecessary requests allows server resources to focus on delivering valuable content and improving overall performance.

1. Evaluate each script, image, or CSS style to confirm its usefulness.
2. Consolidate files and resources that can be combined without affecting functionality.
3. Use web auditing tools to identify and purge any extra requests.

These actions will improve the loading speed and contribute to a cleaner and more efficient web architecture. When optimizing web pages, less is more when it comes to non-essential HTTP requests.

14. Optimize the Website Database

Optimize your website's database by going down one more layer in the architecture. This procedure is vital to improving performance and accelerating your digital platform. Here are some steps you can follow:

1. Examine and remove obsolete or redundant data that may slow down your system.
2. Use specialized tools or plugins to automate the cleaning and maintenance process.
3. Perform regular reviews to ensure the database is in the best possible condition.

Implementing these changes will enhance your page's agility and contribute to better server resource management by managing and accessing a smaller database.

In WordPress, this can mean removing transients or old revisions from posts and pages. It can also involve deleting tables or data from plugins that you once installed but that have already been deleted, leaving garbage in your database.

15. Reduce Cron Activity

Another action you can take is to adjust the frequency of scheduled tasks, commonly known as cron jobs. These tasks can impact your site's loading speed if they run less often. Therefore, to optimize the operation of your website, I recommend that you:

1. You analyze which tasks are essential and how frequently they should be performed.
2. Reconfigure intervals so that critical tasks run outside of peak traffic hours.
3. Use plugins or specialized tools that help space out cron events.

It is not usually very critical, but you can notice an improvement if a heavy execution of a scheduled task coincides with access from a user or a Google crawling bot.

16. Avoid and reduce 301 Redirects

You should be careful with permanent redirects, known as 301 Redirects. These may seem harmless at first glance, but their excessive or incorrect use can lead to digital mazes that slow down your site. Minimizing their use is essential to maintaining a smooth user experience and optimal performance.

• Scan your website for unnecessary redirects and remove them.
• Restructure the site architecture to make navigation more direct.
• Use specialized tools to detect and correct redirect chains.

How to Measure Your Web Performance Metrics

To improve your page speed, the first thing is to measure to have reference values ​​and know how much it improves or if it compensates. Some of the most relevant include:

1. First Contentful Paint (FCP): This indicator measures the time until the first content on the page is displayed, providing an initial estimate of loading time.
2. Time to Interactive (TTI): This metric reflects the time until the page becomes fully interactive, ensuring that elements respond appropriately to user interaction.
3. Largest Contentful Paint (LCP): Quantifies the time it takes for the most significant content on the page to be visible, which is crucial for the user's perception of the site's speed.
4. Cumulative Layout Shift (CLS): This value measures the page's visual stability, ensuring that unexpected movements do not affect the browsing experience.

These metrics and other analysis tools will give you a comprehensive view of your site's performance and highlight opportunities to boost it.

The Influence of Core Web Vitals on Web Optimization

Core Web Vitals, a Google initiative, has become a fundamental pillar in optimizing web performance. These indicators are crucial for evaluating a website's health from the end user's perspective.

Core Web Vitals cover three  essential aspects  of the user experience:

1. Largest Contentful Paint (LCP):  Measures the time it takes for the page's main content to be visible to the user. Ideally, this process should happen in 2.5 seconds or less.
2. First Input Delay (FID):  Evaluates interactivity and responsiveness. It refers to the time it takes for a page to be interactive. A good FID is less than 100 milliseconds.
3. Cumulative Layout Shift (CLS): Quantifies the page's visual stability. Unexpected content skips can be frustrating, so a low CLS is preferable.

Why Pay Attention to Them?

Giving your attention to these factors is not merely a matter of compliance but also a strategy to improve user loyalty and satisfaction. An optimized website loads quickly and provides a smooth and intuitive experience, essential for keeping users engaged and reducing bounce rates.

So, when making adjustments to your website, consider these vital components as a compass guiding you toward a destination of online success. Core Web Vitals are more than just metrics; They reflect the experience you offer each visitor. Pay attention to them, and you'll be on your way to providing an amicable site for your users.

Furthermore, the final goal is to position as best as possible on Google, so what better way than to keep the metrics that Google uses at optimal levels. You don't have to obsess over obtaining the maximum 100 points, but the higher this score is, the better it will be for us in the eyes of the search engine.

Final thoughts

Optimizing the performance of any page or web application must always be considered. Users are becoming less patient, and every second we reduce the website's loading can be crucial to offering a good user experience and keeping them on the website.

On the other hand, search engines like Google or Bing are also sensitive to this since they seek to offer their users a good experience. They do this by offering search results that contain the information the user is looking for but also offer a good experience. So, to position results, they will also take into account the loading speed, indexing fast sites better.

We should also not forget mobile optimization. Many users access it with low-end or slightly old mobile phones that have a harder time handling many elements on the screen.

So, we recommend optimizing the loading speed as much as possible but without going crazy. Obtaining a score of 100 in the Google Core Web Vitals tools is often very difficult, and going from 90 to 100, for example, will not significantly differentiate us in terms of the number of visits.

On the other hand, if we have a website with many animations or that seeks to have a great visual impact on users, it may be more difficult to optimize—or at least at the optimization levels of other websites. In these cases, it may be preferable to maintain the aesthetics and sacrifice some of the optimizations. It's a matter of valuing it.
