There was a time when fast web sites were considered an advantage. Today, this is not an advantage anymore. This is the necessity. Website users expect your web pages to be loaded in seconds, and Google rewards sites that offer seamless user experience. Your website will lose visitors, rankings and sales, and you will not notice this.
Website owners usually do not realize it, but there are several Common WordPress Mistakes that can slow down their websites. They include from incorrect installation of too many plugins to the lack of proper image optimization.
This Guide offered by The Articlez will help you understand 25 Common WordPress Mistakes that Slow Down Websites and optimize WordPress for better performance, SEO and user experience.
Why WordPress Website Speed Matters
The speed of a WordPress site influences the following directly:
Google rankings
Web Vital Metrics
SEO effectiveness
Website bounce rates
User experience
Conversion rates
It has been officially confirmed by Google that page speed plays a crucial role when it comes to ranking pages. Poor performance may drive users off even before the page is loaded.
It is easy to check how well your site performs through Google PageSpeed Insights, which shows the areas of weakness like CSS, JavaScript, Images and Caching.
25 Common WordPress Mistakes That Hurt Website Speed
Choosing Cheap Web Hosting
Poor web hosting is one of the main causes of website slowness. Shared hosting having less resources can’t handle the traffic properly.
Fix:- Go for managed WordPress hosting with SSD storage and caching.
Installing Too Many Plugins
One of the most frequent errors made on WordPress sites is the installation of too many plugins.
Each plugin brings additional PHP code, CSS, or JS to slow down your page.
Fix:- Manage your plugins properly and delete those which are not needed anymore.
Ignoring WordPress Updates
Update skips may lead to low performance levels and security threats.
Fix:- WordPress maintenance involves updating:
WordPress core
Themes
Plugins
Large Size Images Uploads
Large size images take much time in website loading.
Fix:- Image optimization involves compressing images before upload.
Not using Lazy Loading
Every image takes a lot of time to load.
Fix:- Use lazy loading.
Not Using Caching
Without any cache, WordPress regenerates pages each time anyone comes to view them.
Fix:- Use caching plugins or caching on the server level.
Overlooking Browser Cache
Browser cache helps visitors get faster loading of your site pages.
Choosing Unnecessary Themes
There may be many useless animations and other unnecessary elements included.
Fix:- Pay more attention to light themes.
Insufficient Database Optimization
As the time goes by, there may be lots of unnecessary things in the database.
Fix:- Optimize database regularly.
Missing a CDN
CDN is delivering files from servers near the users.
That greatly enhances WordPress speed optimization.
Too Many External Scripts
Fonts, ads, social widgets, and third party scripts make more requests.
Minimize external resources as much as possible.
Neglecting CSS Optimization
Large CSS files prevent rendering.
Fix:- Optimize CSS by:
Minimizing CSS
Removing unneeded CSS
Combining where needed
Neglecting JavaScript Optimization
Heavy JavaScript affects page rendering.
Fix:- Optimize JavaScript by applying deferred loading and minification.
Absence of Mobile Optimization
Most site users are mobile users.
Bad mobile optimization results in low rankings and bad user experience.
Using Too Many Fonts
Each additional font slows down loading time.
Use less font families and font weights.
Adding Too Many Videos
Embedded videos affect the speed of pages.
Instead, add video thumbnails.
Not Compressing Files
Enable GZIP or Brotli for more speedy pages.
Ignoring Core Web Vitals
Google tracks:
Largest Contentful Paint
First Input Delay
Cumulative Layout Shift
Enhancing Core Web Vitals is beneficial for SEO.
Ineffective Plugin Management
Unused plugins pose security threats.
Remove plugins that are not needed anymore.
Failing to Clear Spam Comments
Hundreds of spam comments increase the size of your database.
Website maintenance is critical to keep your site healthy.
Using Untuned Homepage Design
Having too many sliders, animations, and widgets can slow down the homepage.
Stick to clean and minimalist design.
Not Doing Website Performance Tests
Most of the website owners don’t track their sites’ performance.
Test your site regularly using Google PageSpeed Insights to find new problems.
Ignoring Dead Link Issues
Broken links take up crawl budgets and negatively impact SEO.
Perform regular website audits.
Poor Theme Customization
Using excessive page builders and visual effects decrease your website’s performance.
Consider effective customization techniques.
Failing to Optimize WordPress
Most of the users start working on their websites and do not optimize them anymore.
WordPress optimization is crucial as plugins, themes, and content keep growing over time.
