The speed of a website<\/strong> has become a key element in the success of any digital project or company with an online business. Whether it is a corporate site, a blog, an eCommerce or a showcase site.<\/p>\n\n

Load times<\/strong> directly affect the user experience<\/strong>, search engine rankings, and conversions that result from increased visibility, notoriety, and authority in one’s industry.<\/p>\n\n

Today’s visitors, who are used to increasingly fast and fluid browsing, are little patient with <\/strong>sites that are slow and may abandon a page if the loading time is too long. <\/p>\n\n

Therefore, optimizing the speed of your site is important to ensure that people stay and interact with your content. Also because Google values abandonments (Bounce Rate<\/strong> or bounce rate), as a negative experience, and takes this into account when ranking sites in the various SERPs (Search Engine Results Page<\/em>).<\/p>\n\n

That’s why it pays to do a website performance check<\/strong> and, if necessary, implement some optimization techniques, such as compressing images, reducing unnecessary code, implementing browser caching, and optimizing source code. These practices can further help improve loading speed and the overall user experience on your site.<\/p>\n\n

With the use of suggestions and guidance from some speed testing tools<\/strong>, critical points can be identified to take corrective measures and improve the overall results.<\/p>\n\n

In this article you\u2019ll learn how to optimize the speed of a site, both on desktop and mobile, what slows it down, how to control performance to improve user experience, search engine rankings and conversion results.<\/p>\n\n

Website speed test: recommended tools<\/h2>\n\n

One way to evaluate the performance of your website is to subject it to speed tests. A recommended tool for this purpose is Google’s PageSpeed Insights<\/strong>. To learn more read the article we wrote on how to interpret PageSpeed data<\/a>. <\/p>\n\n

This tool analyzes your site and provides an assessment of its performance, identifying potential problems and suggesting solutions to improve loading speed.<\/p>\n\n

To be specified, to tell the truth, that the results of the test are not always the most reliable, in the sense that as always you have to evaluate every aspect in the light of awareness. The tool expresses its score (0-100) on the basis of analyses that are not always true.<\/p>\n\n

Therefore, it is good to test with other analysis software.\u00a0<\/p>\n\n

In addition to Pagespeed Insights there are other tools for testing site speed, among them, GTmetrix, Pingdom Tools, and WebPageTest<\/strong>.<\/p>\n\n

Some allow you to choose the country from which to test, and this contributes to more truthful data.<\/p>\n\n

All evaluate factors that Google considers fundamental, such as loading time, the size of resources, the optimization of HTML code, the essential signals.<\/p>\n\n

Common errors and solutions to speed up the website<\/h2>\n\n

Delete unnecessary Redirects to reduce redirections<\/h3>\n\n

Redirects can negatively affect the loading speed of the site. They are implemented to prevent visitors from landing on a 404 page, non-existent, but it is true that an excess of redirections slows down the loading time and the speed of the site.<\/p>\n\n

The solution is to minimize the number of redirects and make sure they are necessary and well configured.<\/p>\n\n

Check for unnecessary redirects and replace them with direct links to the landing page. Also, consider using 301 redirects instead of 302, as the former are permanent and can be cached in your browser, thus reducing loading time.<\/p>\n\n

Enable and leverage browser cache to improve your site speed<\/h3>\n\n

Use the “Cache-Control” HTTP header to specify how your website\u2019s resources should be stored in the user\u2019s browser cache.<\/p>\n\n

The browser cache is thememory in each browser that stores files that do not change<\/strong>, which remain static on the website, among them the logo, product images, CSS files, etc.).<\/p>\n\n

By storing the files on the user\u2019s computer or device, you will improve the loading speed of your site, as the files will not have to be downloaded every time, on each new visit.<\/p>\n\n

Use a cache plugin to improve the performance of a WordPress site<\/h3>\n\n

If you\u2019re using WordPress as a platform for your website, you can leverage caching plugins to improve your site\u2019s speed.\u00a0<\/p>\n\n

Some plugins<\/strong>, such as WP Super Cache, W3 Total Cache, and WP Rocket,<\/em>allow caching of generated resources, reducing the time it takes to dynamically generate content for each request. This means that visitors will receive content more quickly.<\/p>\n\n

Choose a good hosting<\/h3>\n\n

Choosing a suitable hosting plan is another important factor to improve the loading speed of your website.\u00a0<\/p>\n\n

A low-priced host can give you the idea of convenience, but in the long run you\u2019ll find that the problems, with an initial saving, are many. And your site is at stake. Because even if it optimizes everything, a slow server still penalizes speed.<\/p>\n\n

Select a reliable provider<\/strong> that offers high performance and adequate resources to handle the heavy traffic load. Here’s how to transfer your domain to new hosting<\/a>.<\/p>\n\n

Use a Content Delivery Network (CDN)<\/h3>\n\n

If your site discloses content that reaches different regions of the world, so if your services and products also travel abroad, and your pages are accessible by users from other countries, consider a CDN.\u00a0<\/p>\n\n

In practice, when the server receives a request, the one closest to the user<\/strong> is used, benefiting the reduction of latency time and loading speed.<\/p>\n\n

A Content Delivery Network is a worldwide distributed network that stores a copy of your website\u2019s resources, such as images, scripts, and CSS files.\u00a0<\/p>\n\n

Optimization of the site resources<\/h2>\n\n

Reduce the weight of images and compress them<\/h3>\n\n

Due to their weight, images can be a cause of slowing down a page. Therefore, it is important to optimize them to reduce the file size, without compromising visual quality.<\/p>\n\n

In this regard, use more current and web-friendly image formats<\/strong>, such as JPEG or WebP, SVG, and compress images using software such as Photoshop, Gimp or TinyPNG (for both PNG and JPG), an online platform.<\/p>\n\n

Refer resources that block the display<\/h3>\n\n

View-blocking resources, such as JavaScript and CSS, can delay page loading. It is advisable to delay the loading of these non-critical resources or to use techniques such as CSS inlining<\/strong> to reduce initial rendering times and allow faster display of the main page content.<\/p>\n\n

Choose a lightweight and optimized theme<\/h3>\n\n

Choosing a lightweight, optimized template can go a long way toward optimizing site speed.Avoid heavy, complex themes that take a lot of resources to load. Instead, opt for optimized themes with clean and lightweight code<\/strong> that allow for quick display of content.<\/p>\n\n
