The Bucket With a Hole
Imagine you are paying to fill a bucket with water — paying per litre. But the bucket has holes in the bottom.
No matter how much water you pour in, the level never rises.
This is what most businesses are doing when they run Google or Facebook Ads to an underperforming website. The ad budget is the water. The holes are a slow load time, a confusing layout, and a missing call-to-action.
You are not losing money to the ad platform. You are losing it to the website.
What the Numbers Say
WordStream’s 2025 Google Ads Benchmarks report — based on analysis of over 16,000 campaigns — puts the current averages clearly:
- Average click-through rate across all industries: 6.66%
- Average conversion rate across all industries: 7.52%
That means for every 1,000 people your ad reaches, approximately 67 click through — and only 5 convert at the industry average.
The word “average” is key. Well-optimized local business landing pages can reach 12–15% conversion rates. Underperforming sites drag at 2–3%. The gap between those two numbers is not the ad budget — it is the website.
Every variable in that funnel is affected by your website quality. A faster, cleaner, trust-optimized page does not just improve conversions — it reduces your cost per acquisition (CPA) dramatically. Doubling your conversion rate is mathematically identical to cutting your ad spend in half.
Google’s Hidden Tax on Bad Websites
Google Ads uses a Quality Score — a 1–10 rating assigned to each keyword you bid on. It directly controls how much you pay per click.
Three factors determine your Quality Score:
- Expected Click-Through Rate
- Ad Relevance
- Landing Page Experience
Landing Page Experience is graded on load speed, mobile-friendliness, relevance, and ease of navigation. Google penalizes poor experiences with higher costs.
A Quality Score of 4 vs. 8 on the same keyword can mean paying 2–3x more per click for the same ad position. Your competitor with a better website is buying the same customer at half your cost.
The Correct Order of Operations
Most businesses make the same mistake: they run ads first and try to fix the website later.
Fix the foundation first. Then scale.
- Audit your website performance. Run Google PageSpeed Insights. If your mobile score is below 70, fix it before touching the ad budget.
- Simplify your conversion path. One page, one goal, one call-to-action. Every additional option reduces conversion rate.
- Add social proof above the fold. Reviews, certifications, or a single compelling testimonial — visible before the user scrolls.
- Then, and only then, scale ads.
A website that converts at 15% instead of 3% means the same Rp 10 million ad budget produces 5x the leads. That is the compounding return of getting the foundation right.
The Math That Changes Everything
| Scenario | Monthly Ad Spend | Conversion Rate | Leads Generated | Cost Per Lead |
|---|---|---|---|---|
| Below-average website | Rp 10,000,000 | 3% | 30 | Rp 333,000 |
| Industry average | Rp 10,000,000 | 7.5% | 75 | Rp 133,000 |
| Optimized website | Rp 10,000,000 | 15% | 150 | Rp 67,000 |
Same budget. Same ads. Five times the outcome at the top end. The only variable is the website.

Common Questions About Ads and Website Performance
What is a good conversion rate for a local business website?
WordStream benchmarks suggest 2–5% is average across industries. Optimized local business landing pages can reach 8–12%. If you are below 2%, the website needs work before any ad budget is justified.
Does Google Ads penalize slow websites?
Yes. Google's Quality Score directly factors in Landing Page Experience, which includes load speed and relevance. A poor Quality Score means you pay more per click than competitors with faster, better-optimized pages.
What should I fix on my website before running ads?
Prioritize: page load speed under 2 seconds, a single clear call-to-action, mobile responsiveness, and social proof above the fold. These four changes alone can double conversion rates.
