How Google Ads Work (And Why They Fail for Most Businesses)

Article by Rachel Peters

When businesses think about quick ways to drive leads and sales online, Google Ads often comes first. With billions of searches happening every day, it’s no wonder companies want their business to appear right when potential customers are looking.

While Google Ads can be one of the most profitable marketing channels, it’s also one of the easiest ways to waste money if you don’t know what you’re doing. That’s why working with a Google Ads expert often makes the difference between scaling profitably and burning through budget with no results.

In this article, we’ll break down how Google Ads really work, why most campaigns fail, and how a Google expert can help you turn your account into a revenue-generating machine.

How Google Ads Work: The Basics

At its core, Google Ads is a marketplace. Businesses bid on keywords that people search for, and Google decides which ads to show based on a combination of:

  • Bid amount (how much you’re willing to pay for a click)
  • Quality Score (how relevant your ad and landing page are to the keyword)
  • Ad Rank (Google’s calculation of your bid × quality score)

The process looks like this:

Search → Ad Impression → Click → Landing Page → Lead or Sale

The goal is simple: to match your solution with a user’s intent at the right moment. But while the process sounds straightforward, most businesses run into problems because they skip the strategy behind it.

Why Most Businesses Fail with Google Ads

Google Ads doesn’t just fail because the platform doesn’t work; it fails because of how campaigns are set up and managed.

Here are the top reasons:

1. Targeting the Wrong Keywords

Many businesses go broad, targeting high-volume terms like “lawyer” or “plumber” instead of intent-driven searches like “emergency plumber near me.” A Google Ads expert knows how to balance traffic with buying intent.

2. Poor Landing Pages

Even if your ads get clicks, a slow, confusing, or irrelevant landing page kills conversions. Google rewards relevance, so a mismatched landing page not only reduces leads but also drives up your cost per click.

3. No Negative Keywords

Without negative keywords (phrases you don’t want to trigger your ad), you’ll waste money on irrelevant clicks. For example, a business selling luxury watches doesn’t want to pay for clicks on “cheap watches.”

4. Lack of Ongoing Optimisation

Many business owners set up campaigns and leave them running. But success with Google Ads comes from constant optimisation—adjusting bids, testing ad copy, refining targeting, and improving landing pages.

5. No Clear Conversion Tracking

If you don’t track leads or sales properly, you can’t measure ROI. Too often, campaigns look like they’re working (“lots of clicks!”) but in reality, the sales pipeline is empty.

 

How a Google Ads Expert Turns Failure Into Success

This is where a Google expert or certified digital partner makes a difference. Instead of throwing money at the platform, they build campaigns strategically:

  • Keyword Research with Intent in Mind – choosing terms that drive buyers, not browsers.
  • High-Performance Landing Pages – ensuring clicks turn into real leads or sales.
  • Negative Keyword Strategy – eliminating wasted spend.
  • Conversion Tracking Setup – knowing exactly which keywords and ads generate ROI.
  • Ongoing Optimisation – continually refining campaigns based on data, not guesswork.

The difference between success and failure with Google Ads isn’t luck—it’s expertise.

When to Bring in a Google Expert

If you’re currently:

  • Spending money but not seeing leads or sales
  • Unsure where your budget is going
  • Frustrated with inconsistent results
  • Running your own campaigns without a clear strategy

…then it’s time to partner with a Google Ads expert who can act as your trusted digital partner.
