The Challenge

The Starting Point

For an engineering group, the corporate website is where tender evaluators, procurement teams and potential hires check credentials before they pick up the phone. Many of these sites run on WordPress, are built once and then left alone. Over time plugins pile up, updates are skipped and the site slows down, until it is slow, insecure and quietly losing enquiries.

This group's site had 27 plugins, nine of them out of date, and a theme that had not been updated in three years. It scored 31 on mobile PageSpeed, took 5.6 seconds to load on a phone and had gone down twice in the past year, once after a malware injection. Bounce rate on mobile was 71%, and the site produced about 18 enquiries a month from its contact and tender forms.

What We Did

What We Did

Phase 1, Week 1

Audit and Backup

We took full backups, set up a staging copy of the site and audited every plugin, script and image, recording what each one did and whether it was still needed.

Working on a staging copy meant the live site never broke during the work. The audit showed that many plugins were doing jobs the theme or a single tool could handle. The staging copy also gave the group's IT team a safe place to review changes before anything went live.

Phase 2, Week 2

Clean-up and Security

We removed 14 plugins that were unused or duplicated, updated the rest, cleaned the remains of the earlier malware, and added a firewall, login protection and daily off-site backups.

Every unused plugin is a possible way in for attackers. Fewer, updated plugins made the site both faster and safer. The firewall also blocked thousands of login attempts in the first month alone, which showed how exposed the old site had been.

Phase 3, Week 3

Speed Optimisation

We compressed and resized images, moved them to modern formats, set up page caching and a content delivery network, deferred non-essential scripts and replaced a heavy slider on the homepage.

Large images and scripts loading all at once were the main reasons the site took 5.6 seconds on a phone. Fixing them brought load time under two seconds. The homepage slider alone had been loading more than four megabytes of images before anything else could appear.

Phase 4, Week 4

Testing and Launch

We tested every page, form and download on mobile and desktop, checked that tender and contact forms reached the right inboxes, then pushed the changes live with no downtime.

A faster site is no use if a form silently fails. Testing every enquiry path protected the leads the site was there to collect. The tender form, which brings in the most valuable enquiries, got extra testing with large file attachments.

Phase 5, Months 1 to 3 after launch

Ongoing Maintenance

We moved the site onto a monthly maintenance plan with weekly updates, uptime monitoring, security scans and a short monthly report on speed and enquiries.

Speed and security fade without upkeep. Regular maintenance kept the site at its new standard instead of slowly sliding back. The monthly report also gave management a simple view of the site's health without needing to understand the technical detail.

The Results

The Results

Three months after launch, the site scored 89 on mobile PageSpeed and loaded in 1.9 seconds on a phone. Uptime reached 99.98%, every plugin was up to date and there were no further security incidents. Mobile bounce rate fell from 71% to 52%, and the site produced 27 enquiries a month instead of 18. The group's business development team also reported that tender evaluators no longer mentioned the site being slow or hard to use. Because maintenance is now routine, the site is kept at this standard each month instead of drifting back.

Key Takeaways

What We Learned

Fewer plugins, faster site

Removing 14 plugins that were unused or duplicated did as much for speed as any optimisation tool. Every plugin should earn its place.

Maintenance is cheaper than recovery

One malware incident cost more time and trust than a year of maintenance. Weekly updates, backups and monitoring keep that from happening again.

Speed shows up in enquiries

A corporate site is often the first check a buyer or evaluator makes. Cutting mobile load time to under two seconds kept more of them on the site long enough to get in touch.

FAQ

Frequently Asked Questions

Aim for the main content to appear in under 2.5 seconds on a phone. This group's site went from 5.6 seconds to 1.9 seconds after four weeks of work.
Yes. Plugins and themes need regular updates to stay secure, and sites slow down as content and plugins pile up. Regular maintenance is far cheaper than recovering from an attack or a crash.
Usually very little. Most of the work happens behind the scenes in images, scripts and caching. Here, the only visible change was replacing a heavy homepage slider.
This one took four weeks, including an audit, clean-up, optimisation and testing on a staging copy so the live site was never affected.
