Most sites get faster from a few changes: compressing and resizing images, turning on page and browser caching, removing unused plugins and scripts, and hosting on a server with modern storage and a fast web server. This guide shows you how to do each one, in order of impact.<\/p>\n<h2>Why website performance matters<\/h2>\n<p>Visitors leave slow pages, especially on mobile data. Speed also affects search: Google uses Core Web Vitals, a set of real-user measurements, as part of its page experience signals. A faster site makes it easier for people to read, buy, book or send an enquiry.<\/p>\n<p>Performance work is never finished. New plugins, larger images and extra tracking scripts slowly undo earlier gains, so check your site regularly.<\/p>\n<h2>Step 1: Measure before you change anything<\/h2>\n<p>Run your most important pages, not only the home page, through Google PageSpeed Insights. It shows two kinds of data:<\/p>\n<ul>\n<li><strong>Field data<\/strong> from real Chrome users over the past 28 days, if your site has enough traffic.<\/li>\n<li><strong>Lab data<\/strong> from a simulated test, which is useful for finding causes but varies from run to run.<\/li>\n<\/ul>\n<p>Focus on the three Core Web Vitals. Google&#8217;s &#8220;good&#8221; thresholds are:<\/p>\n<ul>\n<li><strong>Largest Contentful Paint (LCP):<\/strong> 2.5 seconds or less. How quickly the main content appears.<\/li>\n<li><strong>Interaction to Next Paint (INP):<\/strong> 200 milliseconds or less. How quickly the page responds to taps and clicks.<\/li>\n<li><strong>Cumulative Layout Shift (CLS):<\/strong> 0.1 or less. How much the page jumps around while loading.<\/li>\n<\/ul>\n<p>Write down your results so you can compare after each change.<\/p>\n<h2>Step 2: Fix your images<\/h2>\n<p>Images are often the heaviest part of a page. To reduce their weight:<\/p>\n<ul>\n<li><strong>Resize<\/strong> images to the largest size they are actually shown at. A photo straight from a phone camera is far bigger than any web page needs.<\/li>\n<li><strong>Compress<\/strong> them. Most images can lose a lot of file size with no visible difference.<\/li>\n<li><strong>Use modern formats.<\/strong> WebP and AVIF are usually much smaller than JPEG or PNG at similar quality, and current browsers support both.<\/li>\n<li><strong>Lazy-load<\/strong> images further down the page so they load only when the visitor scrolls near them. Do not lazy-load the main image at the top of the page, as that delays LCP.<\/li>\n<li><strong>Set width and height<\/strong> on images so the browser reserves space and the layout does not shift.<\/li>\n<\/ul>\n<h2>Step 3: Turn on caching<\/h2>\n<h3>Page caching<\/h3>\n<p>Dynamic sites such as WordPress build each page from PHP and database queries. Page caching saves the finished HTML and serves it to the next visitor, which cuts server work and time to first byte. On LiteSpeed servers, the free LiteSpeed Cache plugin for WordPress handles this at the server level.<\/p>\n<h3>Browser caching<\/h3>\n<p>Cache headers tell browsers to keep images, CSS and JavaScript locally, so returning visitors do not download them again. Most caching plugins and good hosting configurations set these for you.<\/p>\n<h3>Object caching<\/h3>\n<p>For busy WordPress sites and online shops, an object cache such as Redis stores the results of repeated database queries in memory.<\/p>\n<h2>Step 4: Cut unnecessary code<\/h2>\n<ul>\n<li><strong>Remove plugins you do not use.<\/strong> Each active plugin can add scripts, styles and database queries.<\/li>\n<li><strong>Review third-party scripts.<\/strong> Chat widgets, social feeds, heat maps and several analytics tags can each add noticeable delay. Keep only the ones that earn their place.<\/li>\n<li><strong>Minify and combine<\/strong> CSS and JavaScript where it helps, and defer scripts that are not needed for the first view.<\/li>\n<li><strong>Limit web fonts.<\/strong> Use one or two font families, only the weights you need, and font-display: swap so text appears straight away.<\/li>\n<li><strong>Choose a lightweight theme<\/strong> rather than a heavy page builder layout for simple sites.<\/li>\n<\/ul>\n<h2>Step 5: Use a CDN<\/h2>\n<p>A content delivery network keeps copies of your static files on servers in many cities and serves each visitor from a nearby one. It also absorbs traffic spikes and filters some malicious traffic. Cloudflare has a data centre in Harare, which helps for Zimbabwean visitors. Tremhost Armor sets up and monitors Cloudflare for you; see <a href=\"https:\/\/tremhost.com\/armorguard\">Armor Guard<\/a>.<\/p>\n<h2>Step 6: Keep the software up to date<\/h2>\n<ul>\n<li>Run a supported PHP version. Newer PHP releases are generally faster and receive security fixes. In cPanel you can change the version per site; the Help Centre explains how to <a href=\"https:\/\/tremhost.com\/help\/change-php-version\">change your PHP version<\/a>.<\/li>\n<li>Keep your CMS, theme and plugins updated, and test major updates on a staging copy first.<\/li>\n<li>Clean up your database: old revisions, spam comments and expired temporary data add bulk over time.<\/li>\n<\/ul>\n<h2>Step 7: Make sure your hosting is not the bottleneck<\/h2>\n<p>If your time to first byte is slow even with caching, the server may be the limit. Things that matter:<\/p>\n<ul>\n<li><strong>Storage:<\/strong> NVMe drives handle database reads and writes faster than older SATA drives.<\/li>\n<li><strong>Web server:<\/strong> LiteSpeed is designed to serve pages efficiently and integrates with its own cache.<\/li>\n<li><strong>Resource isolation:<\/strong> on shared hosting, CloudLinux gives each account its own CPU and memory limits, so a busy neighbour cannot slow your site.<\/li>\n<li><strong>Enough resources:<\/strong> a site that regularly hits its plan limits needs a bigger plan or a VPS.<\/li>\n<\/ul>\n<p>Tremhost <a href=\"https:\/\/tremhost.com\/sharedhosting\">web hosting<\/a> runs on cPanel with LiteSpeed, NVMe storage and CloudLinux on every plan, from $30 a year. For WordPress sites where you would rather not handle updates and caching yourself, managed WordPress hosting includes tested updates, daily backups and Cloudflare Pro on every site.<\/p>\n<h2>Step 8: Monitor and repeat<\/h2>\n<p>Re-test after each change and keep a simple log. Check the Core Web Vitals report in Google Search Console every month. When you add a plugin, a tracking tag or a new page template, test again.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>What is a good page load time?<\/h3>\n<p>Aim to meet Google&#8217;s Core Web Vitals thresholds: LCP of 2.5 seconds or less, INP of 200 milliseconds or less and CLS of 0.1 or less, measured on real users.<\/p>\n<h3>Will a faster site rank higher on Google?<\/h3>\n<p>Speed is one of many signals. Relevant, useful content matters more, but a slow site can lose visitors before they read that content.<\/p>\n<h3>Which change usually makes the biggest difference?<\/h3>\n<p>For most small sites, resizing and compressing images and turning on page caching give the largest improvement for the least effort.<\/p>\n<h3>Do I need a VPS for a fast website?<\/h3>\n<p>Not usually. A well-built site on good shared hosting loads quickly. Consider a VPS when your site regularly hits plan limits or needs custom server software.<\/p>\n<h2>Next step<\/h2>\n<p>If your server is holding your site back, move to <a href=\"https:\/\/tremhost.com\/sharedhosting\">Tremhost web hosting<\/a> on LiteSpeed and NVMe. Migration from another cPanel host is free and typically done within 24 hours.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Measure first, then fix images, caching, unnecessary code and hosting.
