How the auction works
When someone searches, Google decides which ads to show based on your bid, the quality of your ad and landing page, and the expected effect of your extensions. You pay when someone clicks, not when your ad appears. A relevant ad pointing to a relevant page can win a spot at a lower cost than a vague ad that points to your homepage.
Costs per click vary widely by trade and by area, and they change over time. Look at the estimates inside your own account instead of trusting round numbers from articles.
Start with search campaigns on specific keywords
Local businesses usually do better beginning with Search campaigns on keywords that show strong intent, such as 'emergency plumber' or 'tax preparer near me,' than with broad awareness. Group keywords by service so each group has its own ad and its own landing page.
Match types control how closely a search must match your keyword. Exact and phrase match give more control, while broad match gives Google more room to interpret. Start tight and expand only after you see real search terms.
Use negative keywords from day one
Negative keywords stop your ads from appearing for searches you do not want. A roofer might exclude 'jobs,' 'free,' 'training' and 'DIY.' Review the search terms report weekly at the beginning, add irrelevant phrases as negatives, and note new ideas for keywords that bring good inquiries.
This one habit often separates a profitable account from a wasteful one.
Target the area you actually serve
Set locations to the places you can reach, and check the setting that decides whether people who show interest in an area count as well as people physically there. Exclude areas you do not serve. Use a schedule that matches the hours you answer the phone, or use call extensions only when someone can pick up.
Add your address through a linked Business Profile if you want location details to appear, and keep your hours accurate.
Track what matters
Before spending, set up conversion tracking for form submissions and calls from ads and from your website. Without it, you only know clicks, not customers. Imported tracking from your analytics tool can work, but test it by submitting a form yourself.
Keep a simple log of how many calls were real leads and how many became jobs, because platform numbers do not know about a quote that closed three weeks later.
Know your limits and alternatives
Set a monthly budget you can afford to lose while learning, and check the account regularly, especially in the first weeks. Automated recommendations from Google often push for more spending, so read them skeptically. Local Services Ads are a different product with their own setup and verification steps, worth looking into for some trades.
If you hire someone to manage ads, ask for your own account ownership, access to reports and clear fees, and keep the ad account in your name.
Common questions
How much should I spend on Google Ads?
Choose a test budget that covers enough clicks to learn, then compare cost per lead with what a customer is worth. See the budgeting guide for ways to think about it.
Do ads help my regular search ranking?
No. Paid ads and organic results are separate. Ads give immediate visibility but stop when you stop paying.
This guide is general information. Search engines change how they work and their guidelines; check Google's current documentation for your situation. Nobody can guarantee a ranking.
