Fix Your Site Before You Spend More on Ads

Le Ventures November 14, 2025 4 min read

Most brands hit a wall with paid ads and decide the solution is to spend more.

Sometimes that’s right. But often the problem isn’t the ads — it’s what happens after the click. Visitors land on your site, look around, and leave without buying. You spend more to bring more of those same visitors, and more of them leave without buying.

More traffic into a leaky funnel just costs more.

Before you increase your ad budget, look at what’s happening on your site.

Where the Money Leaks

There are four points in the funnel where most commerce brands lose sales.

The landing page.

If you’re running paid traffic to your homepage, stop. Your homepage is for browsers. People who came from an ad had a specific reason to click — show them something specific. A landing page matched to the ad’s promise converts 2-3x better than a homepage.

Also: load time. If your page takes more than 3 seconds to load on mobile, you’re losing people before they even see your offer. Check your Core Web Vitals in Google Search Console.

The product page.

This is where most of the real decision-making happens. Common problems:

The single highest-leverage change on most product pages is adding more social proof — reviews, user photos, specific numbers. “Over 10,000 sold” is more convincing than a paragraph of copy.

The cart.

Cart abandonment rates average around 70%. That means 7 out of 10 people who add something to their cart don’t buy.

Some of that is normal — people use carts like wishlists. But a lot of it is friction: unexpected shipping costs, a checkout that requires account creation, too many fields to fill out.

The fastest fix: show shipping costs earlier (on the product page, not at checkout), and let people check out as guests.

The checkout.

Every additional step in checkout loses people. The best checkouts are one page, ask for the minimum information needed, and show trust signals (SSL badge, money-back guarantee, accepted payment methods) right next to the payment form.

Also: if you’re not offering multiple payment methods — at minimum Apple Pay, Google Pay, and PayPal alongside credit cards — you’re losing mobile buyers who don’t want to type their card number.

How to Find Your Biggest Leak

You don’t need to guess. The data tells you.

Set up a funnel report in GA4:

  1. Sessions that viewed a product page
  2. Sessions that added to cart
  3. Sessions that reached checkout
  4. Sessions that completed a purchase

Each step will show you a drop-off rate. Where do you lose the most people? That’s where you start.

A healthy funnel looks roughly like:

If any of those numbers are significantly lower, you have a specific problem to fix.

What A/B Testing Actually Means

A/B testing means showing two versions of a page to different visitors — half see Version A, half see Version B — and measuring which one gets more purchases.

It sounds simple, but most brands do it wrong:

The highest-value things to test:

Run one test at a time. Let it run until you have at least 200 conversions per variant. Then decide.

The Math That Makes This Worth It

Here’s why CRO pays off faster than most ad spend increases:

Say you’re getting 10,000 visitors a month and converting at 2%. That’s 200 sales.

You have two options:

  1. Double your ad spend to get 20,000 visitors. Cost: significant.
  2. Improve your conversion rate from 2% to 3%. Cost: a few changes to your site.

Option 2 gets you to 300 sales with the same traffic. And that 50% lift in conversion rate now applies to every dollar of ad spend you run going forward.

Fixing your funnel doesn’t just save money now — it makes every future ad dollar more effective permanently.
