Here are a few ways that local businesses can use Google Ads effectively:

1. Use location targeting: With location targeting, you can show your ads to users in a specific geographic area. This can be especially helpful for local businesses that only serve a certain region.
2. Use local keywords: Include keywords related to your location in your ads and landing pages. This can help your ads show up when people search for businesses in your area.
3. Use local extensions: Local extensions allow you to add your business's address, phone number, and other location-specific information to your ads. This can make it easier for customers to find and contact your business.
4. Use Google My Business: Claim and verify your business's listing on Google My Business. This will allow you to show up in Google Maps and local search results, and can help customers find your business.
5. Use mobile ads: Many people use their smartphones to search for local businesses. Consider using mobile-specific ads to reach potential customers on the go.

Overall, Google Ads can be a powerful tool for local businesses looking to reach customers in their area. It's important to carefully plan and manage your campaigns to get the most out of your advertising spend.
