Luckily, Google offers tools to help you find keywords that work well. These tools help you spot relevant terms, understand user intent, and control your ad costs. Here is how to use them for the best results.

Use Google Keyword Planner for Core Keyword Research

The Google Ads keyword research tool is the best place to start. It is free and easy to use if you have a Google Ads account. You enter a product, service, or website URL, and it shows keywords related to your input. It also gives you data on search volume, competition, and keyword cost Google Ads.

When choosing keywords, don’t only pick the most popular ones. Look for words that fit your product and your audience’s needs. Keywords with medium or low competition and decent search volume work best. They are often cheaper and attract better leads.

Pro Tip: Use long-tail keywords. For example, choose “best running shoes for flat feet” instead of “running shoes.” These phrases are more specific, usually cost less, and attract ready-to-buy visitors.

Understand Keyword Match Types

After you pick keywords, you must decide how they trigger your ads. Google Ads has four match types:

  • Broad Match: Shows ads on related searches but can waste budget on unrelated clicks.
  • Phrase Match: Ads show when the exact phrase or close variations are searched.
  • Exact Match: Ads show only when the search matches your keyword search google ads exactly.
  • Negative Match: Prevents ads from showing on unwanted terms.

Mix and match types to find what works. Use phrases and exact matches to keep traffic relevant. Use broad match carefully and add negative keywords to block bad clicks.

Keep Your Ad Groups Focused

Your ad groups should have keywords that fit well together. Don’t put too many keywords in one group. The best number is about 10 to 20 keywords per group, all related to the same topic.

Why? This helps improve your Quality Score. Google rewards ads that match the user’s search well with better placement and lower cost per click. For example, keep “men’s shoes” separate from “women’s shoes” in different ad groups.

Use “Discover New Keywords” to Expand Your List

Google Keyword Planner has a Discover New Keywords tab. It helps you find more keywords based on your main terms or website. You can filter results by location, language, or device.

Filter out brand names or competitor terms you don’t want. Then add related keywords that your audience might search. For example, if your main keyword is “organic coffee,” you could add “fair trade beans” or “low acid coffee” to your list.

This tool is great for reaching new audiences or testing new ideas in your campaign. You can even find keywords related to white hat outreach link building techniques to support SEO efforts alongside your paid ads.

Check Keyword Trends and Forecasts

The Forecast feature in Keyword Planner shows you estimates on clicks, impressions, and costs based on your budget. This helps you see if a keyword is worth targeting.

If a keyword has a high cost but low clicks forecast, it might not be a good choice. Look for keywords with good click estimates and reasonable fees. You can also use Google Trends to check how interest changes over time.

Learn from Competitors to Find Keyword Gaps

Checking what keywords your competitors use can give you new ideas. Tools like Google Ads Auction Insights, SEMrush, or SpyFu show keywords your rivals bid on.

Although these tools are not part of Google Ads, they help you discover keywords you may have missed. Find terms your competitors don’t use well and focus on them in your ads.

Monitor and Optimize Your Keywords Often

After launching your ads, check the Search Terms Report to see what users typed before clicking your ad. This helps you find:

  • Good keywords to keep and boost
  • Bad keywords to block with negative match
  • Keywords to adjust bids on
