WordPress speed optimization is one of many SEO factors that impact ranking performance on all websites. Does your WordPress site’s extremely slow loading bug you? It also negatively affects your search engine rankings – and your customers’ “User Experience” perception too! How to speed up WordPress website page load times became an important issue when Google incorporated this aspect into ranking algorithms.

Why speed up WordPress?

The consensus of opinion is that the following factors are crucial:

  • Mobile first-index has been in place for years – slow sites are now demoted. No problem because visitors hate them anyway.
  • Slow site speed has a negative effect on User Experience – no one likes slow sites!
  • Woocommerce performance optimization sells more products!

WordPress load time optimization requires eliminating unnecessary plugins from your WordPress installation, optimising all images, compressing files etc. and it’s now a critical component of rankings. Of course, better rankings are not the sole reason for carefully reducing your site’s page sizes to increase WordPress performance – your visitors and customers will thank you too!

Bloated websites are particularly problematic when viewing on a mobile device across a 3G / 4G mobile network! In 2023, the highest percentage of visitors to your website will be using a mobile device such as a smartphone or tablet.

Best practices make search engines happy!

The goal should be page sizes under 1 Mb, and Google recommends an “above the fold” load time of under 1 second.

Boost WordPress site speed to improve “above the fold load time” – this is a key part of our WordPress website management services. The overall page load time improvements should positively impact;

  • Visitor retention time
  • Repeat visitor rate and,
  • On e-commerce sites, each 1-second drop increases revenue by 10%

Steps to optimize WP performance

There are many elements you must consider when speeding up your WordPress website performance and page speed… There is a  recommended process;

  1. Benchmarking your site on multiple load speed tests.
  2. Image File Size reductions provide the quickest return on efforts expended. Ensure that all images are correctly sized and compressed. Using a “lazy load” plugin stops images from loading until they enter the viewport.
  3. WP Caching Plugins are essential to improved page speed. I use WP Rocket Cache and Docket Cache.
  4. WordPress Plugins all consume resources, so remove any non-essential items.
  5. Asset Cleanup: provides a way to unload unused CSS and JavasScript code site-side, except for the page it’s required on – for example, contact forms.
  6. Home content should be fast and simple to minimise database requests and page file sizes.
  7. Design Theme – You need a lean, mean marathon running theme. Not bloated, built for comfort and not for speed theme! The “all things for all people” style theme is a disaster…
  8. Hosting Location – should be close to your target market, not on the other side of the planet.
  9. Hosting account settings – check the PHP version is the latest, and optimal performance settings are applied, such as adequate WordPress memory allocation.
  10. Avoid redirects – long redirect chains slow things down.

Our WordPress speed optimization service resolves all possible issues, with the caveat that some themes have limitations.

1 – WordPress benchmarking

Page speed optimisation services must incorporate benchmarking. If you don’t record where you started, you won’t know how far you’ve come.

In order to monitor the incremental changes on pages, you need a range of tools because results can vary between measuring services due to traffic, latency etc. However, consistency in upward or downward trends across multiple test platforms and locations provides a more accurate assessment. Use these…

  1. Page Speed Insights: how Google rates the performance of any page: (https://developers.google.com/speed/pagespeed/insights/)
  2. Pingdom: load performance from 3 test site options; Sydney, Amsterdam, New York or Dallas. (https://tools.pingdom.com/)
  3. GT Metrix: The free website speed analysis service tests access from several countries: (https://gtmetrix.com)

Benchmark website performance

Run the initial test on 3 or 4 services before you start making changes. The process makes more sense if you;

  • Record exactly what you did to optimize website performance
  • Record the result each time you check page loading times…

Generally, work on two pages – Home and an internal page – to monitor load times after each stage.

2 – Optimise image sizes and compress them

Nothing slows a website faster than WordPress users loading camera or phone images straight into your posts or pages. A default WordPress install does not automatically resize and compress images like Facebook etc. Media Library settings and some themes can do a lot in that direction, but you’ve got to configure settings correctly. WordPress website speed is severely impacted by over-sized images and it’s often the main reason for your WordPress website loading slow.

You should optimize images across the entire site should to improve website performance. Background images can be awfully big and inserting 1400 x 1000 pixel images that are not compressed and that then end up “scaled to fit” is a good way to kill your website performance. Conversely, site loading time is greatly improved by tackling this issue.

How to optimize your images

Where you see a recommendation in GT Metrix results relating to “image optimization” you should examine the list to see if there are any large ones that you can quickly process for rapid improvements.

Batch processing existing images in bulk

There are good plugins for automatically processing images across your website such as WP Smush, Imagify and Shortpixel.

I use Shortpixel on all sites I manage – https://shortpixel.com. They offer a 50,000 Image Plan for US$30. You can install the Shortpixel plugin on multiple sites and share that 50k image allocation across all of them.

Batch image processing across an entire site is simple! Just pre-set the plugin parameters for lossless, glossy or lossy and then set the maximum image size etc. and set it to work. There is an option to backup copies of original images, and to restore those if required. The thousands of thumbnails can also be processed.

Lazy loading of images also improves site performance.

Shortpixel makes short work of getting your image library under control!

Where you see a recommendation in GT Metrix or other load speed results relating to “optimise images” you could examine the list to see if there are any very large ones that you can process. The only option is one by one, which is why a fully automated batch-processing tool is a godsend!

Note: GT Metrix give you a link to a compressed version of the file under each image that can/should be reduced. That is very helpful with PNG files as they can be awkward to compress…

  • Click the “See optimised version” to open the compressed file
  • Right-click the image and select “Save as” and make sure the name is identical to the original version
  • Use your FTP software to upload the optimized files to the original folder

Retina ready images:

Not everyone understands that this is Apple marketing at work. It’s a gimmick, where only enabled devices might theoretically show a photo-realistic image… Loading retina-ready images onto the average website is verging on stupid… Yet some website designers will tell you it’s essential. On the average website’s traffic logs, you will see that Apple visitors make up less than 6% of total visitors. Of those, a very tiny percentage actually have retina-ready devices!

Why punish 99% of visitors with huge images and slow load times?

3 – WordPress caching is essential

In the WordPress environment, there are several long-serving and respected caching plugins available at no cost. Perhaps the most well-known are the freebies; W3 Total Cache, WP Super Cache and Quick Cache. I’ve used all three across many different websites over several years as part of WP tech support and maintenance on many sites. A reputable website speed optimization company will generally use premium plugins.

Which Caching Plugins Work Best?

I install multiple caching systems for all sites I manage.

1 Page caching:

WP Rocket Cache plugin. I have a Developer’s Licence for that purpose. It runs happily on Litespeed Web Server too. Features include;

  • The usual Gzip compression on pages
  • Lazy Load images
  • Minimise + combine CSS files and Javascript
  • Runs on Apache and Litespeed servers
  • Pre-load from sitemaps – supports All in One SEO and Yoast SEO XML sitemaps
  • Easy configuration

2 Persistent object caching:

Persistent Object Caches are specialized servers such as Redis or Memcached that provide an in-memory data structure store. In WordPress, the most common function of object caching is caching database and/or MySQL queries. This speeds up a website and reduces the load on the server. However, in my experience it’s really difficult to get Redis or Memcached working – even on premium shared hosting plans!

The two plugins that do work easily on almost every shared hosting site I’ve tested are:

  • SQLite – very simple “plug and play” and it usually works as advertised…
  • Docket Cache – somewhat more complicated as there’s a plethora of settings to work through but it’s robust and has worked for me on sites that didn’t seem to like SQLite and vice versa. It can even manage post revisions…

3 OP Cache:

From inside cPanel’s PHP options, ensure that opcache (and memcached) is activated. OPcache is a caching engine built into PHP. It dramatically improves the performance of websites based on PHP. Each PHP file is precompiled then cached.(Control of OPCache is included in Docket Cache)

OPcache enhances PHP performance caching precompiled script bytecode into shared memory. Effectively eliminating any requirement for PHP to load and parse scripts on every request.

When you have all 3 caching mechanisms (Page, MySQL & PHP) functioning, there’s a significant improvement and these are key to Google speed optimization boosts on Core Web Vitals. The Time To First Byte improvement can be significant… even on so-called “optimised WordPress hosting” plans.

4 – Plugins impact on performance

All plugins consume some web server resources – some are horrendous at increasing page sizes and generating excessive WordPress database requests. A WordPress plugin may load its code on every page even though it may only be used on one page. Some are so badly coded that their server resources usage impacts negatively on managed WordPress hosting environments and some hosting companies have banned them – e.g.;

  • Related posts plugins that generate ridiculous quantities of database queries
  • Statistics plugins pulling data from other sites

Not all plugins are beneficial to performance. A plugin has a quantifiable impact on page load speed, page file sizes and database requests. Indeed, some add hundreds of lines of code to every page, and trigger high volumes of database requests. This can cripple “shared hosting” web servers, and some hosting providers have banned such plugins. Remove unused plugins because they are a security risk even when inactive.

The worst culprits are invariably broken link checkers and related content generators.

Twofer plugins

Two for One Plugins: In some cases, a plugin serves a dual purpose, allowing you to achieve a couple of desirable outcomes without increasing the consumption of resources. An example might be a social widget that offers both Like buttons and Follow links to your social media business pages. multiple purposes.

Be very careful of Jetpack – it is the Swiss Army knife of plugins but is very resource-hungry!

Lite Plugins: Unlike beer, the “Lite” version is often full-strength without the weight of unnecessary features in competing plugins. Sure, it may also be the Free vs. the Pro version.

Remember to keep your plugins updated to the latest version!

Security plugins

Some security plugins include features that you don’t need to run all the time. For example, the respected Wordfence plugin offers Live Traffic logging which is a bit resource hungry. Turn it off if you don’t need it. The scanner has options for image scans and ultra-sensitive modes – run those once and then deactivate them to reduce resource consumption.

I usually run two security plugins, but care has to be taken that they complement each other and don’t generate conflicts that increase the time it takes pages to load.

If one of your plugins is a Web Application Firewall, don’t use another plugin that also has a WAF – or deactivate its WAF function.

Heartbeat control

The WordPress Heartbeat API can sometimes generate high server loads, negatively impacting performance. that slow things down significantly. If you suspect that’s happening, there is a Heartbeat plugin that can minimise this issue. WP Rocket Cache has Heartbeat control in the Settings.

5 – Asset Cleanup

The Asset clean-up plugin provides a way to deactivate all trivia in WordPress – the things a business website doesn’t normally use. That includes comments, version ID, XML RPC, emotions and more. Individual CSS and JavaScript can be loaded only on pages it’s needed. The overall impact is fewer HTTP requests and less unused code per page. It also provides tools to preload fonts etc.

6 – Home complexity

Striking a balance between showcasing what your site offers and keeping the page size within sensible constraints is the challenge here. In your quest to determine how to speed up website performance, keep in mind that Home is the most important page in the entire site in terms of new visitors landing on it. Website management services include speed optimization is crucial to keeping them there long enough to captivate their interest.

Sometimes less is more… Show them fewer choices in terms of recent posts, latest comments, slide shows, tags, categories and featured pages or posts, top post lists etc.

When planning how to improve website loading speed, remember that a fast page is crucial to keeping a visitor’s attention long enough to grab their interest. Achieving a compromise between highlighting high-quality website content and loading it as fast as possible is the conundrum.

Keep it closer to 1 Mb than 2 Mb, and have it load in less than 3 seconds… To achieve that, trim numbers in terms of posts, comments, slideshows, tags, categories, featured pages & posts, top post lists etc.

External content can slow things down significantly;

  • Don’t load the Facebook Statistics for your Business page, only show the Follow buttons
  • The same goes for Tripadvisor etc
  • If you are running Ads, check what impact your supplier’s code is having.
  • If you are loading external fonts and icons, see if your caching plugin can cache them!
  • Host fonts locally, or use “system” fonts for the fastest speed.
  • Don’t load Google Analytics in your admin area – log into GA to view data instead.

7 – Design themes

These are not all created equal, so be sure to choose a lightweight theme from a reputable developer who provides direct customer support. Usually, a full-featured WordPress theme is bloated to the point of obesity. Very few are designed from the ground up for load speed performance and SEO rankings… Be aware that if you want stellar performance, a slow WordPress design is a liability and not an asset.

Some of the fastest and best WordPress themes available, according to multiple reviews, are as follows:

8 – Hosting location

Hosting location can make a significant difference to page load times. If your website targets New Zealand clients, then a server physically located in New Zealand makes sense. Otherwise, the inherent “latency” in a US or Canadian-based server adds a second or more to load times!

Where’s your site hosted

If you are a New Zealand business targeting clients in the USA, it would make perfect sense to have your site with a hosting provider with a data centre in the USA. Doing so could reduce load time by 5 seconds or more! That’s a dramatic improvement AND the hosting costs are likely to prove less expensive… Conversely, if your clients are in NZ, that’s a good place to be hosted.

Example – this site

This site is now housed on an A2Hosting server in Singapore and runs on Cloudflare. It has been optimised with WP Rocket Cache and the Shortpixel image optimisation plugin. It has;

  • Approx 2 seconds in New Zealand, Australia, the UK, USA etc.

Given that most of my clients are NZ and Australian small businesses, the Cloudflare functionality makes perfect sense.

Content delivery network CDN

A content delivery network like Cloudflare makes a huge difference to performance and security. The FREE plan is well suited to most WordPress websites – and the Cloudflare APO for WordPress is perfect for Woocommerce sites.


With some time and effort, your site’s core web vitals SEO and page speeds can (in most cases) be dramatically improved. First, check the current performance and then ensure that you are using the best caching option for your site. Next, evaluating plugin resource consumption and replacing greedy ones will trim resource consumption to the bare minimum. Remember that all web hosting is not created equal and saving a few dollars a month could cost you thousands.

Follow that by optimising image dimensions and applying compression so pages load faster. Complete the process by looking closely at your Home content. Consider your design theme… Ask yourself if it’s bloated code filled with functions you don’t use or need is an asset or a liability. Are rankings more important than fancy effects, slideshows and huge images?
