A slow website isn’t just annoying — it’s costing you customers. Here’s how Innovative Digital Marketing fixed a Brisbane business’s site speed in under a week, and what happened to their leads when we did.
If your website feels a little slow, you’ve probably told yourself it’s not a big deal. Visitors will wait. It probably doesn’t affect much.
It does. And we have the numbers to prove it.
Earlier this year, a Brisbane-based service business came to us frustrated. They were spending money on Google Ads, getting decent traffic, but the leads just weren’t coming through the way they expected. Their conversion rate was low, their bounce rate was high, and nobody could quite figure out why.
We ran a Google PageSpeed audit on their site within the first ten minutes of our initial call.
It scored 41 out of 100 on mobile.
For context: Google considers anything below 50 “poor.” A score of 41 means your site is actively working against you — pushing you down search rankings, driving visitors away before your page even loads, and telling every potential customer who does land on your site that you’re not worth their time.
Within five days, we had that score sitting at 94. Within 30 days, their monthly lead volume had tripled.
Here’s exactly what we found, what we did, and what changed.
Why Website Speed Is a Lead Generation Problem, Not Just a Technical One
Before we get into the specifics, it’s worth understanding why a slow website doesn’t just feel bad — it directly kills your business results.
Google uses speed as a ranking factor. Since the 2021 Core Web Vitals update, Google has factored page loading speed into search rankings. A slow site doesn’t just frustrate visitors — it actively gets deprioritised in search results, meaning fewer people even find you in the first place.
Visitors don’t wait. Research consistently shows that 53% of mobile users will leave a website if it takes more than 3 seconds to load. For every additional second of load time, conversion rates drop by roughly 4.5%. Our client’s site was loading in 6.2 seconds on mobile. You do the maths.
For service businesses, first impressions are everything. If someone in Brisbane searches for your service, clicks your ad or listing, and then waits six seconds for your page to load — they’ve already decided something about your business. They’re probably clicking back to Google and calling someone else.
A fast website tells visitors you’re professional, credible, and worth their time before they’ve read a single word.
What We Found in the Audit
When we ran a full technical audit on the client’s site, the issues were significant — but they were also entirely fixable. This wasn’t a case of needing to rebuild from scratch. It was a case of a site that had been built without performance in mind, and had never been properly optimised after launch.
Here’s what we found:
Uncompressed, oversized images. The homepage alone had eleven images uploaded at full resolution from a camera or phone — 4–6 MB files being loaded on a mobile screen. Image weight was the single biggest contributor to slow load times.
No browser caching. The site wasn’t configured to store any resources in a visitor’s browser, meaning every page visit — including repeat visits from the same person — loaded all assets from scratch every time.
Render-blocking scripts. Several JavaScript and CSS files were loading before the page content, meaning the browser had to wait for those files to finish before it could show the visitor anything. The page appeared blank for seconds at a time.
An oversized, poorly coded theme. The WordPress theme was loaded with features the site never used — page builders, WooCommerce dependencies, custom font libraries — all running in the background on every page load.
No content delivery network (CDN). All assets were being served from a single hosting server. Visitors on mobile networks or further from the server experienced significantly longer load times.
Slow shared hosting. Server response times alone were adding over a second to every page load.
Combined, these issues were adding roughly 4.4 seconds to the site’s load time. Most visitors never made it past that.
What We Did — Day by Day
We work methodically, testing after each change so we know exactly what’s moving the needle. Here’s how the week played out.
Day 1 — Image Optimisation and Compression
We started with the highest-impact fix first. Every image was compressed, converted to WebP format, and resized to the maximum dimensions they’d actually display at. Images that had been 4–6 MB came down to 80–120 KB without any visible quality loss.
We also implemented lazy loading — images below the fold don’t load until the user scrolls toward them, so the initial page load only carries what the visitor actually sees first.
PageSpeed after Day 1: 41 → 67 Load time: 6.2 seconds → 3.8 seconds
Day 2 — Caching and CDN Setup
We configured browser caching so static assets — images, fonts, CSS — cache for 30 days in the visitor’s browser. We also connected the site to Cloudflare’s CDN, distributing assets across global servers. For a Brisbane business, this meant assets served from Sydney and Melbourne edge servers rather than a single shared host.
PageSpeed after Day 2: 67 → 78 Load time: 3.8 seconds → 2.6 seconds
Day 3 — Script Cleanup and Render-Blocking Fixes
We audited every JavaScript and CSS file loading on the site. Render-blocking scripts were deferred — loading after visible content rather than before it. Several scripts from unused plugins were removed entirely. We also minified remaining CSS and JavaScript files, reducing their size by 20–40%.
PageSpeed after Day 3: 78 → 86 Load time: 2.6 seconds → 2.1 seconds
Day 4 — Hosting Migration
The shared hosting environment had a ceiling we couldn’t push past through optimisation alone. Server response times were sitting at 780ms. Google recommends under 200ms.
We migrated the site to a managed WordPress VPS with guaranteed resource allocation. Server response time dropped to 140ms within an hour.
PageSpeed after Day 4: 86 → 91 Load time: 2.1 seconds → 1.9 seconds
Day 5 — Core Web Vitals Fine-Tuning
The final day was about pushing from good to excellent. We focused on Google’s three Core Web Vitals ranking metrics:
Largest Contentful Paint (LCP): The time for the biggest visible element to load. We preloaded the hero image and above-the-fold fonts, dropping LCP from 4.1s to 1.4s.
Cumulative Layout Shift (CLS): How much the page jumps as it loads. We set explicit dimensions on all images and embeds to eliminate layout shift.
First Input Delay (FID): How quickly the page responds to the first user interaction. Resolved by the script cleanup on Day 3.
Final PageSpeed Score: 94 out of 100 Final load time: 1.8 seconds
The Results — 30 Days Later
The goal was never a high score on a speed tool — it was more leads. Here’s what the 30 days before versus the 30 days after looked like:
| Metric | Before | After | Change |
|---|---|---|---|
| PageSpeed score (mobile) | 41 | 94 | +129% |
| Average page load time | 6.2s | 1.8s | -71% |
| Bounce rate | 71% | 47% | -34% |
| Average session duration | 48 sec | 2m 14s | +180% |
| Monthly form submissions | 11 | 34 | +209% |
| Monthly phone call clicks | 7 | 19 | +171% |
| Total monthly leads | 18 | 53 | +194% |
Total leads went from 18 to 53 per month — without any change to the ad budget, the content, or the offer. The same traffic, converting at a dramatically higher rate, simply because the site was fast enough to keep them there.
The client’s cost per lead dropped from $88 to $29. On the same monthly spend.
What This Means for Your Brisbane Business
Every week a slow website is live, you’re paying for traffic that’s bouncing. Every Google Ad click that lands on a 6-second load time is money spent on someone who left before they saw your offer.
Website speed is not a nice-to-have. For Brisbane businesses competing for local search visibility, it’s one of the highest-leverage improvements you can make — and in most cases, the fixes are far simpler and faster than people expect.
The quickest way to know where you stand: go to PageSpeed Insights and enter your URL. If your mobile score is below 70, there’s room to improve. Below 50, and speed is actively costing you business right now.

Key Optimizations for Achieving a 98/100 PageSpeed Score
Achieving a high PageSpeed score is not just about speeding up a website—it’s about optimizing both the front-end and back-end performance for the best user experience. In our case, we focused on several strategies to make the website faster without compromising functionality.
This included optimizing image sizes, reducing HTTP requests, leveraging browser caching, and minifying CSS and JavaScript files. By using these techniques, we were able to reduce page load times significantly, making the site not only faster but also more responsive across devices.
“A website’s speed is crucial for both SEO and user retention. Every millisecond matters, and a faster website leads to better user experience and higher conversion rates.”
Prioritizing Performance While Maintaining Aesthetics
One of the biggest challenges when optimizing for speed is balancing design aesthetics with performance. To maintain a beautiful and functional website while optimizing for speed, we leveraged lazy loading for images and videos, reducing the initial load time significantly. We also used modern front-end frameworks and a Content Delivery Network (CDN) to ensure fast loading times no matter where the user is located.
Throughout the process, we continually tested and refined the website, ensuring it stayed visually appealing while enhancing its performance.
