How Does Google Ads Work?
Google Ads (formerly Google AdWords) operates on a Pay Per Click (PPC) model. You define which search keywords you want to appear for, how much you'll pay per click, and what the user sees in your ad. When someone clicks, you pay. When nobody clicks, you don't pay.
What Determines How Much You Pay Per Click?
Google runs a real-time auction every time someone searches. The Cost Per Click (CPC) is determined by:
- Competition for the keyword: the more businesses bidding on it, the more expensive it gets
- Quality Score: a score Google gives your ad based on relevance, expected CTR, and landing page quality
- Your bid: how much you're willing to pay per click
Average CPC for Google Ads varies from $1 to $15+ depending on the industry. Lawyers, insurance, and real estate are among the most expensive. Specific local services are usually cheaper.
How Much Budget Do You Need for Google Ads?
This is the first question every business owner asks, and there's no single right answer. But here is a realistic framework:
Under $300/month: Hard to Get Meaningful Data
With such a low budget, there's not enough data for optimization. You might get a few leads, but it's hard to know what's working and what isn't.
$400 to $800/month: A Reasonable Starting Point
For most small businesses with a specific, local service, this is enough to get about 30 to 80 clicks per day and collect initial data. By the end of the first month, you'll already know if the campaign is generating more than it costs.
$800 to $2,200/month: An Effective Budget
Allows you to test multiple keywords, multiple ads, and optimize seriously. This is the range where most small-to-medium businesses achieve a positive ROI.
Important to know: From the total budget, you need to subtract management fees (if you hire an expert), typically 15% to 25% of the total budget, or a fixed amount of $130 to $530 per month.
What Is the Difference Between Search and Display?
Google Ads includes two main types of advertising, and understanding the difference is important:
Search Ads: Advertising in Search Results
These are the ads that appear at the top and bottom of Google results. The user has already searched, so they have buying intent. This makes Search Ads extremely effective for closing warm leads.
Suited for: any business that wants customers with clear buying intent. Lawyers, contractors, florists, dentists: all can benefit from Search Ads.
Display Ads: Advertising on External Websites
Banner ads that appear inside other websites (news sites, blogs, etc.). The user didn't ask for it; the ad comes to them.
Suited for: branding, remarketing (showing ads to people who visited your site), and campaigns aimed at awareness rather than immediate sales.
Which Is Better for a Small Business?
Always start with Search. The budget reaches people who searched for you, and the results are measurable and clear. Add Display later for remarketing, to remind people who visited your site but didn't call.
5 Common Mistakes That Waste Money
Most businesses that try to manage Google Ads on their own make at least three of these mistakes:
Mistake 1: Keywords That Are Too Broad
Advertising on "renovation" instead of "apartment renovation in Austin" is like putting a sign on a highway in Texas for a restaurant in Maine. Pay only for what's relevant to your business.
Mistake 2: Not Adding Negative Keywords
If you're a contractor, you don't want to appear for "DIY renovation" or "renovation on a zero budget." Negative keywords block irrelevant searches and save tens of percent of your budget.
Mistake 3: A Bad Landing Page
You paid $5 per click, the customer arrived, and landed on a page that loads slowly, doesn't contain what the ad promised, and has no clear action button. Money wasted. The ad brings visitors; the landing page closes deals.
Mistake 4: Launching a Campaign and Never Touching It
Google Ads requires weekly monitoring. What's working? What's wasting money? Which hours produce the best leads? A good campaign manager optimizes consistently.
Mistake 5: Not Setting Up Conversions
If you don't define "what counts as success" (phone call, form submission, purchase), Google can't optimize on your behalf. Conversion Tracking is the most critical tool in Google Ads.
What to Expect in Return: Real ROI
Let's talk in honest numbers. Here is a realistic scenario for a local service business (for example, an HVAC technician):
- Monthly budget: $800
- Average CPC: $2.15
- Number of clicks: ~375
- Conversion rate to lead: 8% (reasonable)
- Number of leads: ~30 per month
- Closing rate: 40%
- Closed deals: ~12 per month
- Average deal value: $160
- Revenue from campaign: $1,920
- ROI: 2.4x on the investment
This is a realistic ROI for a well-managed campaign. A poorly managed campaign can yield a negative ROI. The difference is in the management.
Manage Yourself or Hire an Expert?
This is the million-dollar question, and the answer depends on several factors:
Manage Yourself If:
- Your budget is under $530/month (management fees would eat too large a share)
- You have the time to learn: at least 5 to 8 hours for initial learning
- You enjoy analyzing data and experimenting
Hire an Expert If:
- Your budget is over $800/month: a good expert will save more than they cost
- You don't have time to manage campaigns alongside running your business
- You tried managing yourself and didn't see results
- Your industry is very competitive
