Every month, Australian businesses collectively waste millions of dollars on Google Ads by sending paid traffic to websites that aren't set up to convert. It's the digital equivalent of filling a leaky bucket — no matter how much you pour in, the result is the same. Before you increase your Google Ads budget, work through this list. Fixing even three or four of these issues typically delivers better ROI than any campaign optimisation.
Leak 1: Your Page Loads in More Than 3 Seconds on Mobile
Google's own data shows that as page load time goes from 1 to 5 seconds, the probability of a visitor bouncing increases by 90%. For paid traffic — where you're paying for every click — sending people to a slow page is like burning money. Test your site with Google PageSpeed Insights, and if your mobile score is below 70, make this your first priority. Common fixes include compressing images, removing unnecessary plugins, and upgrading to faster hosting.
Leak 2: There's No Clear Call to Action Above the Fold
"Above the fold" refers to the portion of the page visible without scrolling. If a visitor lands on your page and can't immediately see what action they should take, a significant percentage will leave within seconds. Your primary CTA — call us, book online, get a quote — should be visible and prominent before any scrolling is required, on both desktop and mobile.
Leak 3: Your Landing Page Doesn't Match Your Ad
This is called a message mismatch, and it's one of the most common and expensive errors in Google Ads. If your ad promises "Same-Day Emergency Plumbing Melbourne" but the landing page it goes to is your generic homepage, visitors feel disoriented and leave. Every ad group should send traffic to a page that specifically fulfils the promise the ad made — with consistent language, a direct response to the need the searcher expressed, and a clear path to conversion.
Leak 4: Your Phone Number Is Hard to Find
For service businesses, phone calls are often the primary conversion event. If a visitor has to hunt through multiple pages to find your number, many won't bother. Your phone number should be in the header of every page, clickable on mobile (click-to-call), and included near every form and CTA. Consider adding a sticky header on mobile that keeps the phone number visible as users scroll.
Leak 5: You're Missing Trust Signals
Visitors from Google Ads often have no prior relationship with your business. They're making a decision about whether to trust you in seconds. The absence of trust signals — customer testimonials, client logos, industry certifications, years in business, genuine photos of your team and work — creates hesitation that converts into bounces. Add these elements prominently on your landing pages, especially near your CTAs.
Leak 6: Your Form Asks for Too Much Information
Every additional field on a contact form reduces completion rates. If you're asking for name, email, phone, budget, project description, timeline, and how they heard about you — you're asking too much from someone who's just landed on your page for the first time. Start with the minimum information you need to make initial contact (name, email or phone, and one brief message field) and collect the rest during the follow-up conversation.
Leak 7: You Have No Follow-Up System for Enquiries
This one isn't technically a website leak — it happens after the conversion — but it's responsible for an enormous amount of wasted ad spend. If a lead comes in via your contact form and doesn't receive a response within a few hours, conversion rates drop dramatically. Studies consistently show that the speed of follow-up is one of the strongest predictors of whether a lead converts into a customer.
Set up an automated email response that acknowledges receipt of the enquiry immediately. Then have a human follow-up process that ensures no enquiry waits more than a few hours during business hours. The leads you're paying Google for deserve a timely response.
Addressing these seven leaks before increasing your ad spend is the highest-leverage thing most Australian businesses can do to improve their Google Ads ROI. The budget you save by not wasting clicks on a broken experience is often more than enough to fund the fixes.
