Page speed is rarely the first thing property business owners think about when their Google Ads are underperforming. It should be. A slow landing page is expensive in at least three distinct ways, and all three affect your bottom line without any obvious warning.
The conversion rate cost
Slower loading pages have lower conversion rates. This is consistently measured across industries, not assumed. A page that loads in one second converts significantly better than one that loads in four seconds. For a campaign spending £2,000 per month, even a one or two percent improvement in conversion rate is worth several hundred pounds per month in lead value.
The mechanism is straightforward: visitors who wait more than a few seconds for a page to load simply leave. The click has already been paid for. The opportunity is gone.
The Quality Score cost
Google's landing page experience metric is a component of Quality Score. A slow page signals a poor user experience and reduces your Quality Score, which increases your cost per click. You pay more for every click on a slow page than you would pay for the same click on a fast one. The compounding effect over months of spend is significant.
The mobile cost
A disproportionate share of Google searches happen on mobile. If your page is slow to load on mobile specifically, which is common with unoptimised image-heavy property websites, you are paying for mobile clicks that have almost no chance of converting. Many property businesses have never tested their landing page on a phone with a realistic connection speed.
How to check your page speed
Google's PageSpeed Insights tool is free, takes 30 seconds, and gives a score out of 100 for both mobile and desktop separately. A score above 90 on mobile is a reasonable target for a high-converting property landing page. Below 50 is a significant problem. The tool also tells you specifically what is causing the slowdown.
The main causes of slow property websites
- Large unoptimised images: a single uncompressed property photo can add two to three seconds of load time
- Unminified CSS and JavaScript files loaded synchronously
- Third-party tracking scripts blocking page render
- Web fonts loading before the page is displayed
- No browser caching for returning visitors
Most of these issues are fixable by a competent developer in a few hours. The cost of not fixing them is paid every month in higher CPCs and lower conversion rates.
What a fast property landing page looks like
A well-built property business landing page can achieve a Google PageSpeed score of 90 or above on both mobile and desktop. At Colonnade, a 90-plus PageSpeed score is a standard requirement on every site built, not an optional extra. If you are running paid traffic to a slow site, fixing the page will almost always deliver a better return than increasing ad budget.
If you would like to understand what a fast, conversion-focused property website includes, the website design service page covers both the performance standards and what is built in by default.
A slow site is costing you leads from every click.
Every Colonnade website is built to load fast on mobile, score above 90 on PageSpeed Insights, and convert the paid traffic it receives.
