9 WordPress Performance Optimization Tips for Busy Agencies
Nobody likes a slow website. According to Google research, one third of web visitors leave the site if it takes more than 3 seconds to load. And the longer it takes, the more visitors it loses to poor performance.
But the website performance doesn’t just affect bounce rates – it also impacts SEO, conversions, and even how people perceive the brand.
If you’re an agency or freelancer managing multiple WordPress sites, you know how time-consuming, tedious – and absolutely essential – performance optimization is.
To help you stay on top of it, here are 9 easy ways to make your sites faster – especially useful when you’re working on a lot of sites at once.
1. Monitor Your Sites All the Time
Step one is always knowing your numbers. Monitoring won’t speed up your sites directly – but you can’t fix what you don’t track. A WordPress management tool like WP Umbrella gives you a centralized dashboard to monitor all your sites in one place and track key metrics like:
- Uptime
- Time to First Byte (TTFB)
- First Contentful Paint (FCP)
- Speed Index
- Time to Interactive (TTI)
- Core Web Vitals
- Google PageSpeed scores
The centralized insights help you spot and react to issues quickly, before they hurt user experience or SEO.
2. Keep Things Updated (Safely)
To keep your sites fast and secure, your WordPress core, plugins, and themes should always be up to date. Otherwise, they’ll slow down your sites and leave them vulnerable to countless security risks.
But with tens or hundreds of plugins across multiple sites, running updates can take hours. And there’s always the risk of breaking something in the process.
To deal with that, WP Umbrella’s Safe Update feature lets you:
- Run one-click bulk updates across all your sites
- Get instant version rollbacks and notification if anything goes wrong.
It’s a faster, safer way to keep every site running smoothly.
3. Manage Your Cache
Use a Caching Plugin to Save Time and Server Power
If you don’t use caching, your websites have to build each page from scratch every time someone visits. This makes your servers work harder than they need to and slows down the sites.
Caching plugins like WP Fastest Cache solve this by saving ready-made versions of your pages. That way, your sites can load much faster for every visitor.
Delete Cache After Updates
Caching only works well if it’s up to date. After you update a plugin (especially one that changes how your site looks or works) it’s important to delete the old cached files. If you don’t, people might see broken pages or outdated content.
If you manage multiple sites with WP Umbrella, you can use your WP Fastest Cache license to automatically clear the cache after plugin updates. This smooth integration saves you time, reduces manual work, and helps keep all your sites fast and running smoothly.
4. Optimize Media for Faster Loading
Compress Images
Those 2MB images on your websites kill your load times fast. We all want sharp, great-looking sites, but most of those big images can be squished down to about 100KB – without losing any sharpness or detail.
Your marketing folks really shouldn’t worry about this, because today’s compression tools, such as WPFacstestCache Image Optimization Feature, are smart enough to keep your images looking almost identical to the original, with no noticeable quality loss.
As a rule of thumb, if your images are measured in megabytes instead of kilobytes – you’re leaving speed on the table.
Lazy Load Everything
After compression, the next step is lazy loading. Lazy loading means images, videos, and other media only load when they’re about to appear on the screen as users scroll, rather than all at once.
This cuts initial load time and makes your sites feel much faster for the visitor.
- Clean Up Your WordPress Database
Your websites’ databases are like rooms that get cluttered over time. Old files, unused plugins, and spam comments are like trash piling up on the floors. If you don’t clean it frequently, the rooms get harder to move around in – therefore your websites get slower too.
Here’s what you can do to clean your databases and keep them organized:
- Remove Unnecessary Revisions – WordPress saves unlimited revisions by default. If you make a lot of changes to a post or page, it will save all of those changes as separate revisions. That’s a lot of clutter. Limit the number of versions it keeps.
- Delete Unused Plugins and Themes – In most cases, the more plugins you have, the slower your site is. If you don’t use something, delete it. After deletion, remove leftover data tables to fully clean your database.
- Clear Spam and Trash Comments – Spam takes up space and makes your site look suspicious. Delete spam comments often. If you don’t want to do this yourself, just use an anti-spam plugin or disable comments entirely.
- Optimize the Database Tables – use phpMyAdmin to optimize your tables. Simple cleanup = reduced storage space = better performance.
- Disable Pingbacks and Trackbacks – These are automated notifications that tell you when other sites link to your content. Although sometimes useful, they can take up space and create clutter. Unless you need them, turn them off.
If you’re not a fan of manual work, all of this can be done with WP Umbrella’s Database Cleanup Feature.
6. Choose a Smart Infrastructure
A Reliable Hosting Provider
Your host is the foundation. If it’s slow, everything else is slow. Choose a hosting provider with fast servers and trustworthy customer support. This is one expense you shouldn’t cheap on.
CDN to Serve Visitors Faster
If your websites have visitors from different countries, adding a CDN (Content Delivery Network) can help a lot. A CDN stores copies of your site on servers around the world and delivers your content from the server closest to each visitor.
This reduces the distance data has to travel, making a site load faster no matter where the visitors are. Faster loading means happier users and more conversions.
7. Opt for System Fonts
Web fonts are pretty. But often not worth the load time. System fonts (like Arial or Helvetica) are already on the user’s device so no downloads are needed.
But if you’re not a fan of system fonts, consider hosting your web fonts locally and preload them to reduce the negative performance impact. Remember: aesthetics matters, but speed wins. Every time.
8. Minify Your Code
Code is not always perfectly organized. But the messier it is, the bigger your files get, and the slower your sites load. To speed things up, you can shrink those files by “minifying” them.
That means cutting out anything that isn’t needed for the code to work – extra spaces, line breaks, notes. Smaller files mean your sites load faster, which keeps visitors happy and helps your site show up better on Google.
Tools like WP Fastest Cache make this easy by automatically minifying your CSS and JavaScript files, so your code stays efficient without extra work on your end.
9. Don’t Let Backups Slow You Down
Backups are super important to keep your websites safe. But they’re not always done right.
Here’s what you can do to ensure they don’t impact performance:
- Start with a full backup, then use incremental backups to save only the changes made since the last one, instead of copying everything all over again. Incremental backups use less storage space and take less time to complete.
- Schedule backups during off-hours when fewer people visit your site. That’s likely late at night or early in the morning.
- Store backups offsite, not on the same server where your website is stored. Not doing so is like keeping all your important documents and their copies in the same filing cabinet. If the cabinet gets on fire, both the originals and the copies are gone. Pro tip: make a backup of your backup. You’ll be glad you did if something goes wrong.
WP Umbrella’s backup and restoration feature makes all this easy by automating your backups and keeping them safely encrypted on a secure GDPR compliant server. It doesn’t even charge extra for it – making it the perfect “backup of the backup” solution.
