What Google Won’t Tell You When You Run Google Search Ads (But You Need to Know)

Google Search Ads can be a powerful tool for driving traffic, leads, and sales. Many people think running them is as easy as “set it up and watch the leads roll in,” but that’s almost never the case. Google gives you a starter kit if you spend enough money with them, but after that, you’re on your own. What they don’t tell you can cost you leads and sales.

I’ve run campaigns and learned lessons the hard way. I won’t list all my mistakes; suffice it to say that optimizing goes beyond mere keyword setup. While there’s too much to cover in one post, here are a few lessons you can’t afford to miss.

1. You get a specialist only when you hit a spend threshold

If your account meets a hidden monthly spend (around $450 to $500), Google will assign a specialist. They’ll hop on a call, walk through dashboards and keywords, and help you get set up.

It’s a good starting point, but from my experience, their focus is mostly on getting you live, not managing your strategy. They won’t dig into your audience, your negative keywords, or your nuanced targeting approach. The comprehensive, in-depth work that turns a campaign from functional to profitable is mostly on you.

Think of Google’s setup as orientation, not optimization. Once that call ends, your results depend on how well you test, refine, and interpret the data. Don’t stop optimizing your campaign once you’ve completed a setup call with Google.

2. Don’t rely on Google to choose your best keywords

Google’s suggestions — whether from a specialist or an automated tool — can be helpful, but they often include keywords that don’t fit your goals or attract the wrong audience. These suggestions are designed to expand reach, not necessarily to improve relevance or profitability.

Start with your core services or products and build from there. Use tight, intentional keywords that match how your ideal customers actually search. Once you have data, you can layer in variations or test new terms, but stay in control of your list.

Pro tip: For long-tail keywords, use broad match to capture natural variations in phrasing. For shorter or more competitive keywords, use exact or phrase match to stay focused on qualified traffic. This article from WordStream provides a nice  overview of matching.

3. Google’s AI keyword generator tool isn’t as smart as you

One tool Google offers pulls keywords from your website via AI. On paper, that’s convenient. In practice, it can be messy.

AI can’t read context or understand your brand voice as well as you. If your site name or content includes playful terms, AI may take them literally. Say your brand is The Chalkboard (an educational tutoring company). Google might import keywords like “chalkboard supplies,” which show your ads to people looking for classroom supplies, not tutoring.

You need to audit the AI’s keyword list, prune what doesn’t fit, and add negative keywords to block irrelevant searches. Speaking of negative keywords…

4. Negative keywords can be a secret weapon, but Google won’t usually set them up for you

Negative keywords are keywords or phrases you add to our search campaign to prevent your ads from showing for irrelevant searches. They help you avoid wasted spend and target only qualified traffic. Thinking back to the chalkboard example, you could list “chalkboard supplies” as a negative keyword to prevent people searching for supplies from seeing your ad. Negative keywords tell Google not to show your ad for certain terms. Without them, your ad can appear in irrelevant searches.

Your specialist might mention negative keywords, but they typically won’t build the ongoing list, refine it, or manage exclusions for you.

5. “Set it and forget it” is a myth

Google Ads is a powerful platform for reaching the right audience, but it is not automatic. Even the best campaign needs regular attention to perform well.

Check the search terms people use, see what is draining your budget, identify what is working, pause what is not, and test new ad copy. Reviewing your campaign at least twice a week can make the difference between wasted spend and meaningful results.

6. Conversions are more important to measure than clicks

Clicks can be helpful, but they only tell part of the story. To see what’s actually driving business, you need to track actions like calls, form fills, or purchases.

If you don’t set up conversion tracking in Google Ads and Google Analytics, it’s hard to know which campaigns or keywords are doing the heavy lifting. It takes a little work to get right, but it’s worth it. I found this article from Stape helpful.

7. Your daily budget can make or break your visibility

People often pick a low daily budget and never touch it. But that can keep your ads stuck in low ranks, never getting the exposure to generate conversions.

I once doubled my daily spend. Yes, the budget ran out faster, but I also got leads that converted. If a keyword costs more, that’s okay (to a point) as long as it brings qualified traffic. Don’t be afraid to spend more, especially early on in the campaign when you’re learning how people react to your brand.  

8. Your landing page is as important as your ad

If your ad drives traffic to your homepage, you’re missing an opportunity. Match the ad’s promise to a custom landing page with a single message, clear offer, and strong call to action. Don’t confuse visitors with multiple competing messages. Make conversion as easy as possible.

Pro tip: Make sure your landing page loads quickly. One study showed that mobile users will bounce if the page takes more than 3 seconds to load.

9. Give it time. Optimization is a journey, not an event

Your first few weeks are your testing phase. Don’t toss the campaign if it doesn’t perform instantly. Watch trends, not day-to-day swings. Adjust, refine, and give the system time to stabilize.
