Pulling a client into your website is a difficult task \u2013 and keeping him might be even a greater challenge. A website that loads even 3 seconds longer than a competitor\u2019s website, most likely will scare a user away.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s why it is worth taking your time and making sure that your website is as efficient as possible, not only for the sake of clients. For quite a time now, Google has been considering the website loading speed \u2013 the better the optimization, the higher position.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So how to make your website work even more effective? We present 6 suggestions to speed up your website.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"measure-website-speed\">Measure website speed<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before you start making changes on the website, it is worth starting by measuring the speed of it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here are few websites which can be used to do such a test:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"keycdn\">KeyCDN<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It is a fast and easy tool, one of its advantages is a wide selection of measurement stations. After analyzing the website, KeyCDN will give a general grade (from F to A) and it will also assess whether the website has particular elements, e.g. lazy load, CSS files, or optimized images.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/tools.keycdn.com\/speed\">https:\/\/tools.keycdn.com\/speed<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"google-pagespeed-insights\">Google PageSpeed Insights<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It is an author\u2019s solution from Google.&nbsp;<a target=\"_blank\" href=\"https:\/\/developers.google.com\/speed\/pagespeed\/insights\/\" rel=\"noreferrer noopener\">PageSpeed \u200b\u200bInsights<\/a>&nbsp;measures the speed of loading and the speed of generating a website in the browser. Website performance is reported both on mobile devices and stationary ones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Website will be graded from 0 to 100, in 3 segments \u2013 red (0-49), yellow (50-89), and green (90-100).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"950\" height=\"640\" src=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-Google-PageSpeed-Insights.jpg\" alt=\"sephora Google PageSpeed Insights\" class=\"wp-image-1156\" srcset=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-Google-PageSpeed-Insights.jpg 950w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-Google-PageSpeed-Insights-300x202.jpg 300w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-Google-PageSpeed-Insights-768x517.jpg 768w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-Google-PageSpeed-Insights-534x360.jpg 534w\" sizes=\"auto, (max-width: 950px) 100vw, 950px\" \/><figcaption class=\"wp-element-caption\"><em>Test of Sephora website, 03.26.2021<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"google-lighthouse\">Google Lighthouse<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s an open-source, automated website audit tool. You can run it on any website \u2013 public or requiring authorization. As in the case of Google PageSpeed Insights, the audit can be conducted on both mobile and stationary devices.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" href=\"https:\/\/developers.google.com\/web\/tools\/lighthouse\" rel=\"noreferrer noopener\">Lighthouse<\/a>, like Google PageSpeed Insights, will run an audit for website performance but also for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Progressive Web App (PWA) \u2013 a specific app or website which can but doesn\u2019t have to mimic the behavior of a native mobile app. At the same time, PWA works perfectly offline. Lighthouse can check such an application.<\/li>\n\n\n\n<li>Accessibility score \u2013 whether images have an alternative description, website language is understandable, the website has a clear structure, etc.<\/li>\n\n\n\n<li>Best practices \u2013 checking whether the elements that work on other websites are available on a given website and how well they work, e.g. using HTTPS, proper usage of a browser, etc.<\/li>\n\n\n\n<li>SEO score \u2013 whether the website is friendly for browsers and mobile devices;\u00a0<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"950\" height=\"640\" src=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/google-lighthouse.jpg\" alt=\"google lighthouse\" class=\"wp-image-1157\" srcset=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/google-lighthouse.jpg 950w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/google-lighthouse-300x202.jpg 300w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/google-lighthouse-768x517.jpg 768w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/google-lighthouse-534x360.jpg 534w\" sizes=\"auto, (max-width: 950px) 100vw, 950px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"gtmetrix\">GTmetrix<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Similarly to KeyCDN, a website will be graded from F to A. The test combines results from various sources \u2013 Google PageSpeed and YSlow, among others from sources. A lot of options are only available in the paid version. However, you can download the test as a PDF \u2013 useful when you want to send it to the board or the client.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/gtmetrix.com\/\">https:\/\/gtmetrix.com\/<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"950\" height=\"640\" src=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-gtmetrix.jpg\" alt=\"sephora gtmetrix\" class=\"wp-image-1154\" srcset=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-gtmetrix.jpg 950w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-gtmetrix-300x202.jpg 300w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-gtmetrix-768x517.jpg 768w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/sephora-gtmetrix-534x360.jpg 534w\" sizes=\"auto, (max-width: 950px) 100vw, 950px\" \/><figcaption class=\"wp-element-caption\"><em>Test of Sephora website, 03.26.2021<\/em><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">However, the tests must be conducted properly to give a measurable result \u2013 below you will find some advice on how to do it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"choose-one-tool-on-which-you-will-rely-or-two\">Choose one tool on which you will rely \u2013 or two<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s not worth comparing results from different tests \u2013 they differ in methodology, infrastructure, and other factors.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"do-a-few-tests-in-a-row\">Do a few tests in a row<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Only some tools do a few tests in a row, giving an average result. If the selected doesn\u2019t provide such a solution, do it yourself.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"just-don-t-test-the-home-page\">Just don\u2019t test the home page<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It is worth testing other subpages. You don\u2019t have to check each page \u2013 the most important are enough, e.g. sale offer, contact, products that you want to promote.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"nearest-measuring-station\">Nearest measuring station<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If there is an option for choosing a location, use it. In that way, you will limit the factors on which you don\u2019t have influence, e.g. delays on fiber optic cables for broadband providers. Ideally, the measurement station is located where the users of your website are \u2013 or at least the majority of them.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"cache\">Cache<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Its task is to store data to which access is often granted, without the necessity to perform each time time-consuming calculations or access external data.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"wp-super-cache\">WP Super Cache<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The plugin generates static HTML files. After generating the file, the server will load it instead of a heavier PHP script.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A static file will be loaded for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>unlogged users,<\/li>\n\n\n\n<li>users who didn\u2019t leave any comments,<\/li>\n\n\n\n<li>users who didn\u2019t view the password-protected post.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">One hidden file can be used many times and other users will receive files customized specifically for them.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"wp-super-cache\">WP Super Cache<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The plugin has 2 versions, premium and free. Even the free version will be enough for an average user, however premium one includes a lot of amenities, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Widget Cache System<\/strong>\u00a0\u2013 widgets caching,\u00a0<\/li>\n\n\n\n<li><strong>Minify HTML, CSS, and JS<\/strong>\u00a0\u2013 diminishing the source code by removing unnecessary, for the machine, characters (line breaking, comments, nonprinting characters) without changing its functionality in HTML,\u00a0<\/li>\n\n\n\n<li><strong>lazy load<\/strong>\u00a0\u2013 while opening the website, loaded are only those images that are currently visible.\u00a0<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"wp-rocket\">WP Rocket<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It works similarly to WP Fastest Cache \u2013 the majority of functions of both plugins overlap with each other, but there are a few differences between them:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>WP Rocket is only available in a paid version.<\/li>\n\n\n\n<li>It offers local storage of the pixel code of Facebook and Google Analytics (tools for monitoring the behavior of users).\u00a0<\/li>\n\n\n\n<li>It uses the WordPress Heartbeat API. It means that API runs a set of tasks at given intervals or &#8220;beats&#8221; every 15 or 60 seconds, using the admin-ajax.php file to handle AJAX requests. It is used by CMS, as well as its plugins and themes \u2013 thanks to this, in the WP cockpit notifications are displayed, drafts of entries are automatically saved and idle users can be logged out.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/wp-rocket.me\/\">https:\/\/wp-rocket.me\/<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"latest-php-version\">Latest PHP version<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It is equally important to have the most up-dated PHP version. Until now, this version has been 7, but on November 26, 2020, version 8 was implemented.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Will the newest version significantly influence the website\u2019s performance? It depends. If your website does a lot of time-consuming math tasks, then yes, version 8th will improve your page flow. However, most \u201cnormal\u201d users won\u2019t fill a difference between PHP 7 and PHP 8.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It should be noted that when using an older PHP version, it is worth checking the list of outdated functions, changes, and problems that may occur before updating.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.php.net\/manual\/en\/appendices.php\">https:\/\/www.php.net\/manual\/en\/appendices.php<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before moving to PHP 8 it is worth making a back-up, so you won\u2019t lose anything in the case of failure. H<a target=\"_blank\" href=\"https:\/\/blog.mserwis.pl\/jak-wykonywac-kopie-zapasowa-10-zasad-backupu\/?utm_source=art%20jak%20przyspieszyc%20strone%20na%20wp&amp;utm_medium=przycisk&amp;utm_campaign=art%20jak%20przyspieszyc%20strone%20na%20wp\" rel=\"noreferrer noopener\">ere we described how to do it<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"image-optimization\">Image optimization<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Equally important is the optimization of images on the website. Properly small graphics mean faster backup and smaller page size \u2013 which saves much-needed space on the server. Think if you need all images \u2013 maybe some of them can be replaced with text?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"jpg-png-and-gif\">JPG, PNG, and GIF<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The format of uploaded graphics to the website is also important. The best option for images with a lot of colors is JPEG. It offers lossy compression that enables high image compression. The side effect is the loss of some details which are generally unnoticeable.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"950\" height=\"640\" src=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/jpg-1.jpg\" alt=\"properties of jpg\" class=\"wp-image-1151\" srcset=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/jpg-1.jpg 950w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/jpg-1-300x202.jpg 300w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/jpg-1-768x517.jpg 768w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/jpg-1-534x360.jpg 534w\" sizes=\"auto, (max-width: 950px) 100vw, 950px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For more complicated images the best option will be PNG format. Unlike JPG, it offers lossless compression which results in a larger file size.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"950\" height=\"640\" src=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/png.jpg\" alt=\"properties of png\" class=\"wp-image-1152\" srcset=\"https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/png.jpg 950w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/png-300x202.jpg 300w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/png-768x517.jpg 768w, https:\/\/dotinum.com\/blog\/wp-content\/uploads\/2021\/03\/png-534x360.jpg 534w\" sizes=\"auto, (max-width: 950px) 100vw, 950px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The last recommended format is GIF, used for animated images. GIF uses only 256 colors and lossless compression.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you want to reduce the size of images even more, use a free image compressor, e.g.&nbsp;<a target=\"_blank\" href=\"https:\/\/tinypng.com\/\" rel=\"noreferrer noopener\">https:\/\/tinypng.com&nbsp;<\/a>or a plugin<a target=\"_blank\" href=\"https:\/\/wordpress.org\/plugins\/tiny-compress-images\/\" rel=\"noreferrer noopener\">&nbsp;https:\/\/wordpress.org\/plugins\/tiny-compress-images\/<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"lazy-load\">Lazy load<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">While opening the website, loaded are only those images that are currently visible. The rest of the content is loaded later as the page is scrolled. Thanks to this, graphics placed further on will not delay the loading of key elements of the website located at the very top.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"content-delivery-network-cdn\">Content Delivery Network &#8211; CDN<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A Content Delivery Network is a distributed network of servers, decreasing the physical distance between a user and a server. Thanks to this, delays in loading the page content are minimized. Currently, most of the network traffic is handled by the CDN.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"cloudflare\">CloudFlare<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CloudFlare places the copy of a website in a cloud, blocks various threats<strong>,&nbsp;<\/strong>and reduces the amount of spam. When the user enters the website, he is redirected to the CloudFlare server instead of an actual server of a given website. It allows avoiding detection of the user&#8217;s server IP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.cloudflare.com\/\">https:\/\/www.cloudflare.com\/<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In WordPress, there is also available a free CouldFlare plugin.&nbsp;<a target=\"_blank\" href=\"https:\/\/wordpress.org\/plugins\/cloudflare\/\" rel=\"noreferrer noopener\">https:\/\/wordpress.org\/plugins\/cloudflare\/<\/a>.
