You should be able to take the URL of those demo sites and run through the same process as above, before comparing that to other themes out there.&nbsp;As long as you keep everything else constant, you\u2019ll get a somewhat DIY comparison between themes which can be quite useful.<\/li><\/ol><ol start=\"2\" class=\"wp-block-list\"><li>It\u2019s also worth doing some research online and leveraging the work of others.&nbsp;There are a lot of <a href=\"https:\/\/wp-rocket.me\/blog\/divi-vs-elementor-performance-speed\/\">speed and performance comparisons online<\/a>, especially of the more popular themes, so it\u2019s worth looking into those as well to get a sense of where your theme sits in the pile. <br>You\u2019re in luck, <a href=\"https:\/\/wp-rocket.me\/blog\/fastest-free-wordpress-themes\/\">WP Rocket already tested the 13 fastest free themes<\/a> of the WordPress ecosystem.&nbsp;<\/li><\/ol><ol start=\"3\" class=\"wp-block-list\"><li>Check <a href=\"https:\/\/www.wpspeedster.com\/\">WPSpeedster<\/a>: they tested almost all the themes from the WordPress repository (they\u2019re using Google PageSpeed to run the analysis.)<\/li><\/ol><h3 class=\"wp-block-heading\">What to do if you encounter an error?<\/h3><p>If you\u2019re running your WordPress website speed test and you encounter an error message of some sort, make sure of the following:<\/p><ul class=\"wp-block-list\"><li>You\u2019ve included the correct URL in the box, without spelling errors.<\/li>\n\n<li>Write \u201chttps\u201d and not \u201chttp\u201d.<\/li>\n\n<li>You don\u2019t have any firewall settings getting in the way depending on geography.<\/li>\n\n<li>Your site is published by your hosting service.<\/li>\n\n<li>The tool you\u2019re using is operating correctly.<\/li>\n\n<li>Your site settings are nominal.<\/li><\/ul><p>If you\u2019re still having trouble, then it\u2019s worth reaching out to the customer support team of that particular tool as they will be well placed to assist you.&nbsp;<\/p><p><strong>Practical tip: <\/strong>If one of the tools shows some errors coming from your website (e.g some downtime) then we suggest you monitor your website. With Pingdom for example you are instantly alerted before your customers even notice.&nbsp;<\/p><h2 class=\"wp-block-heading\">How to Analyse WordPress Speed and Performance Results<\/h2><p>On a high level, here\u2019s how you should think about your speed and performance results:<\/p><ul class=\"wp-block-list\"><li><strong>Performance Grading:<\/strong> Every tool will collate a range of factors and come up with a grading score (often out of 100) that aims to summarize the key factors. The higher the score, the better. This is then broken down into more granular statistics as mentioned below.<\/li><\/ul><ul class=\"wp-block-list\"><li><strong>Load Time:<\/strong> This is sometimes referred to as the First Contentful Paint (FCP) and here you\u2019re looking for it to be as small as possible. The faster the load time, the better.<\/li><\/ul><ul class=\"wp-block-list\"><li><strong>Largest Contentful Paint<\/strong> (LCP): This is similar to the load time and you want it to be as low as possible.<\/li><\/ul><ul class=\"wp-block-list\"><li><strong>First Input Delay<\/strong> (FID): The lower this number the better, because it tracks how responsive a site is to the first interaction which is a key point of the customer journey that sets expectations. If it\u2019s too high, then a visitor is likely to click away.<br><br><strong>Important note<\/strong>: the FID score is only available for Field data so if you don\u2019t have sufficient real-world speed data you can look at the Total Blocking Time (TBT) metric instead. TBT is located in the lab data and both provide a similar analysis.<\/li><\/ul><ul class=\"wp-block-list\"><li><strong>Time to Interactive<\/strong> (TTI): It\u2019s the amount of time it takes for the page to become fully interactive. <em>And what makes a page fully interactive? <\/em>When the page responds to user interactions (like a click on a button) within 50 milliseconds. In other words, this measures the time between the FCP and the TTI and ideally you want to minimize it as much as possible.<\/li><\/ul><p>Each tool will give you very clear visual cues about each factor, often using red, orange, and green to grade performance. You can use these for basic triage, identifying the ones that are most dire, and prioritizing the fixes accordingly.<\/p><h2 class=\"wp-block-heading\">How to Fix Speed and Performance Issues<\/h2><p>You\u2019ll need to look carefully through your test results to identify the ones that are affecting you.&nbsp; However, there are some that are more common than others, so let\u2019s look through some of them at a high level to give you a sense as to what can be done.&nbsp;<\/p><p>Here are the actionable steps that you can take to <a href=\"https:\/\/wp-rocket.me\/blog\/guide-to-page-speed-optimization-for-wordpress\/\">speed up your WordPress site<\/a> after getting a not-so-good result :&nbsp;<\/p><ul class=\"wp-block-list\"><li><a href=\"http:\/\/wp-rocket.me\/blog\/image-optimization-wordpress\/\">Compress your images<\/a> so they aren\u2019t as large in size.<\/li>\n\n<li><a href=\"https:\/\/wp-rocket.me\/blog\/lazy-loading-wordpress-5-5\/\">Lazy load your images<\/a>.<\/li>\n\n<li>Implement a caching solution.<\/li>\n\n<li><a href=\"https:\/\/wp-rocket.me\/blog\/cdn\/\">Use a Content Delivery Network (CDN).<\/a><\/li>\n\n<li>Try using a different theme that performs better.<\/li>\n\n<li>Optimize your databases.<\/li>\n\n<li><a href=\"https:\/\/wp-rocket.me\/google-core-web-vitals-wordpress\/eliminate-render-blocking-javascript-css\/\">Optimize your render-blocking CSS and JavaScript<\/a>.<\/li>\n\n<li><a href=\"https:\/\/wp-rocket.me\/google-core-web-vitals-wordpress\/reduce-javascript-execution-time\/\">Reduce JavaScript execution time<\/a>.<\/li>\n\n<li>Choose a good hosting provider.<\/li>\n\n<li>And much more\u2026<\/li><\/ul><p>All of this work on speed and performance goes hand in hand with SEO, so if you want to appear in the first few Google results, where all of the clicks go, <a href=\"https:\/\/wp-rocket.me\/features\/\">you should always optimize your site using a tool like WP Rocket<\/a>. <\/p><p>WP Rocket is a powerful performance plugin that can deliver significant improvements on your site without you having to do any coding whatsoever.&nbsp;Essentially, the tool proactively builds your website cache after just a few clicks and tweaks as necessary to improve the most relevant performance metrics.&nbsp;<\/p><p>In addition, <a href=\"https:\/\/www.wp-rocket.me\/google-core-web-vitals-wordpress\/\">WP Rocket also optimizes for all the Google Web Vitals<\/a> that are coming in June 2021, so you can be sure that your SEO and general user experience will be natively suited to the Google algorithm.&nbsp;<\/p><p>This can only serve to drive traffic to your site and improve conversions overall:&nbsp;<\/p><figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Performance Issue<\/strong><\/td><td><strong>Testing Tools<\/strong><\/td><td><strong>WP Rocket Features<\/strong><\/td><\/tr><tr><td>Images are too slow.<\/td><td>PSI is best to identify the largest content to load.<\/td><td>WP Rocket and Imagify compress the images without the need for any coding.<\/td><\/tr><tr><td>Sub-optimal caching.<\/td><td>PSI, GTmetrix, WebPageTest, Pingdom<\/td><td>WP Rocket Cache Preloading.<\/td><\/tr><tr><td>CSS and JavaScript files are too large.<\/td><td>PSI (tells you which files) Pingdom, GTmetrix WebPageTest<\/td><td>WP Rocket can combine CSS and JavaScript files to make them faster and lighter.<\/td><\/tr><tr><td>Lack of a Content Delivery Network (CDN)<\/td><td>GTmetrix, Pingdom, WebPageTest&nbsp;<\/td><td>WP Rocket can integrate an external CDN in seconds, or alternatively you can use the native RockedCDN built right into the platform.<\/td><\/tr><tr><td>No GZIP compression<\/td><td>GTmetrix, or Pingdom&nbsp;<\/td><td>WP Rocket adds GZIP compression rules to your .htaccess file automatically<\/td><\/tr><\/tbody><\/table><\/figure><h2 class=\"wp-block-heading\">Wrapping Up<\/h2><p>So, there you have it! Performance scores vary because different tools use different methodologies and configurations.

So even if there is no equal comparison in the tools and in their way of scoring, I\u2019d still advise running the test on PSI so your website is ready for the changes coming in Google&#8217;s algorithm.<\/p><p>For many of these optimizations, <a href=\"https:\/\/wp-rocket.me\/pricing\/\">WP Rocket remains your best weapon<\/a>, as it caches your site automatically.
