Google Ads: What to Expect When You're Expecting Leads

Google Ads is the most powerful paid advertising platform available to small businesses, and also the one most likely to drain your bank account before you realize something is wrong. I've seen businesses generate $40,000 in new revenue from a $3,000 monthly ad budget. I've also seen businesses spend $8,000 in a month and not be able to name a single client who came from it. The difference between those two outcomes has almost nothing to do with Google and almost everything to do with how the campaigns are set up and managed.

If you're considering Google Ads — or you're currently running them without being totally sure whether they're working — this is the context you need. No hype, no guarantees, just an honest explanation of how the thing actually works.

How Google Ads Actually Works

PPC — pay-per-click — means exactly what it sounds like. You pay every time someone clicks your ad. The ad shows up when someone searches for a keyword you've bid on, and you're charged a cost per click that varies based on how competitive that keyword is, who else is bidding on it, and how Google rates the quality of your ad and landing page.

In competitive industries — personal injury law, cosmetic dentistry, addiction treatment — a single click can cost $50 or more. In less competitive local markets, you might pay $4 a click. Neither of those numbers is inherently good or bad. What matters is what happens after the click: does the visitor become a lead? Does the lead become a patient or client? That's the math that determines whether your ad spend is profitable.

Google Ads rewards relevance. The more tightly aligned your ad is with the search term and the more relevant your landing page is to the ad, the lower your cost per click tends to be and the better your ad positions. This is by design — Google wants searchers to find useful results, and they'll give you a pricing advantage if you're genuinely useful.

Quality Score: The Hidden Number That Controls Your Costs

Your quality score is Google's rating of how relevant and useful your ad experience is — from the keyword to the ad to the landing page. It's scored 1 to 10. A quality score of 8 or higher means you'll often pay less per click than a competitor with a quality score of 4, even if you're bidding less. This is one of the most counterintuitive things about the platform: better ads cost less.

Improving your quality score comes down to three things. First, make sure the keywords you're bidding on are tightly relevant to the ad text you're showing. Second, make sure the ad text matches what the searcher is actually looking for. Third, make sure your landing page delivers on the promise the ad makes. Google measures whether users click back quickly after landing on your page. If they do, that's a signal your page wasn't useful, and your quality score suffers.

Most campaigns I audit have mediocre quality scores because campaigns are set up quickly without this alignment in mind. Fixing the quality score issue alone — without increasing the budget — often leads to a 20 to 30 percent reduction in cost per click. That's free money. It's just sitting there waiting for someone to do the work.

Negative Keywords: The Most Underused Feature on the Platform

Negative keywords tell Google which searches should never trigger your ad. They're the list of terms you explicitly don't want to pay for. If you're an oral surgeon, you might exclude searches for "oral surgery recovery tips" or "oral surgery complications" — informational searches that won't generate a patient appointment. If you're a high-end cosmetic dentist, you might exclude "cheap," "affordable," "free," and "Medicaid."

A campaign without a well-developed negative keyword list is one that's bleeding money on irrelevant clicks. I've audited campaigns spending $5,000 a month where 40% of the clicks came from searches that had no realistic chance of converting. That's $2,000 a month in wasted spend — just from not having a basic negative keyword list.

Build your negative keyword list before you launch. Review the search terms report every week for the first few months and add new negatives as you see what's triggering your ads. This is ongoing maintenance, not a one-time task. The campaigns that perform best after six months are almost always the ones with the most refined negative keyword lists.

Conversion Tracking Is Non-Negotiable

If you don't have conversion tracking set up, you have no idea which clicks are leading to business. You can see impressions. You can see clicks. You might be able to see that traffic landed on your contact page. But without conversion tracking, you cannot see which keywords, which ads, and which targeting settings are actually generating phone calls or form fills or purchases.

This sounds technical, but the concept is simple: put a piece of code on your thank-you page or set up call tracking, and Google Ads starts telling you "this keyword generated 4 leads this week at $37 each, that keyword generated 0 leads this week at $68 each." That information is how you allocate your budget toward what works and away from what doesn't.

I'm always surprised how many businesses are running Google Ads without this in place. It's like driving across the country without a speedometer — you're moving, but you have no idea how fast or whether you'll get there before you run out of gas.

ROAS: The Number That Tells You If the Whole Thing Makes Sense

ROAS — return on ad spend — is the ratio of revenue generated to ad spend. A ROAS of 4 means you're generating $4 in revenue for every $1 you spend on ads. For e-commerce businesses, ROAS is relatively easy to calculate because the purchase happens online. For service businesses, you need to track leads through to closed clients, which requires a bit more process but is completely doable.

What constitutes a good ROAS depends entirely on your margins. A business with 80% margins might be profitable at a ROAS of 1.5. A business with 20% margins might need a ROAS of 6 to break even on the channel. Know your numbers before you set expectations. And don't let an agency tell you a campaign is performing well based on click-through rate when you haven't established what ROAS you need to be profitable.

What to Actually Expect in the First 90 Days

Month one is almost always the most expensive and the least efficient. Google's algorithm needs data to optimize. You need data to refine your keywords and negatives. Your landing page might need testing. Expect higher costs per lead in month one than you'll see in month three. If your agency is panicking about month-one results on a brand-new campaign, they either didn't set expectations properly or they've never actually run a campaign before.

By month two, you should see the campaign starting to stabilize. Your quality scores are established, your negative keyword list is growing, and you're starting to see which ad copy resonates with your audience. By month three, you should have enough data to make confident decisions about what's working and what to cut.

Google Ads is not a slot machine. It's not random. It responds to intelligent management. The businesses that get the best results are the ones that treat it as an ongoing system to optimize, not a tap to turn on and leave alone.

Click Fraud: A Real Risk Worth Knowing About

Click fraud is worth mentioning here, even briefly. Competitors and automated bots click your ads without any intention of becoming customers. Google's fraud detection is good but not perfect, and in some industries the problem is significant. We'll cover this in detail in a separate post, but if you're in a highly competitive market and your click volume seems high but conversions seem low, click fraud is worth investigating before you assume the campaign is broken.
