How keywords work
To get your ads to appear when people search for your product or service, the keywords you choose need to match the words or phrases that people search for. When a customer searches for a term that matches your keyword, your ad enters an auction to determine if it will show.
The cost of each keyword varies depending on the quality of your keyword, your competition in the auction, and other factors. Make sure your keywords and landing page are all closely related to the terms that a customer might search for.
Quality Score
To help you understand the quality of your keywords, each keyword used in a Google Ads or Microsoft Advertising campaign has a Quality Score .
This score is based on expected click-through rate, ad relevance, and landing page experience. Higher quality ads and relevant keywords typically lead to lower costs and better ad positions.
How your keywords match to searches
You can use keyword match types to have more control over what searches your keywords match. For example, with exact match , your keyword will only match searches that are identical to your exact keyword, or close variants of your exact keyword. With phrase match , your keyword will match close variants of your exact keyword and may include additional words before or after.
If you don’t specify a match type, your keyword will default to broad match and can match to variations of your keywords.
How to exclude searches
You can also add negative keywords to prevent your ad from showing for particular searches .
Negative keywords can help you reduce costs by making sure your ad shows just to the audience you want. Learn more About negative keywords .
Where your ads appear
You can choose to target your ads to a number of different ad networks. Keywords work a bit differently on each network:
- Search networks on supported platforms : When you build your keyword lists, you select keywords relevant to the terms people use when they search, so your ads reach customers precisely when they're looking for what you offer.
- Google Display Network: If you've set up a Google Ads campaign to show ads on Google Display Network sites, Google Ads uses your keywords to place your ads next to content that matches your ads. Google's technology scans the content and web address of a webpage and automatically displays ads with keywords that closely match the subject or web address of the page. For example, on a webpage that includes brownie recipes, Google Ads might show ads about chocolate brownies or delicious dessert recipes.

- Choose your keywords carefully.Include terms or phrases that your customers would use to describe your products or services. Make sure your keywords directly relate to your ad's theme and the page you're directing your customers to. Keywords of 2 or 3 words tend to be the most effective.
- Group similar keywords.Try grouping your keywords into themes. These themes can be based on your products, services, or other categories. For example, if you sell rings, you can have a group of keywords for "engagement rings" and another group of keywords for "wedding rings." Then, you can create separate ad groups for these groups of keywords and have specific ads for "engagement rings" and specific ads for "wedding rings."
