Before you begin

Once you know how to find data for your keywords, you're ready to work on improving them. A good way to start is by looking for and removing duplicate keywords.

Improve your keywords' relevance

You'll want to make sure that your keywords are relevant to your product or service. That way, customers are more likely to click your ad as they search for specific terms, which can help improve your clickthrough rate (CTR) and Quality Score. Think about it: if you run a floor waxing business, you probably don't want your ad showing to people searching for hair waxing salons. Here are some ways you can improve your keywords' relevance:

• Try replacing a single-word keyword with terms or phrases Use keywords of two to three words that potential customers are likely to use to describe your product or service. In some cases, this means you'll want to make keywords that are too general more specific.

  Broad keyword	Specific keyword
  waxing	wood floor waxing
  floors	floor waxing services
  cleaning	floor cleaning services

• Make sure your keywords are relevant to the ads in your ad groups. Let's say the ads in your ad group are about the services you specifically provide for pine wood floor waxing. You might want the keywords in that ad group to include the term pine wood. You can try using keyword insertion to dynamically update your ad text to include one of your keywords that matches a customer's search terms.
• Group your keywords by themes based on your product or service. And make sure your ads are about your keyword themes. That way, we can show more relevant ads to potential customers when they're searching for a specific product or service. You can also look at how your company's website layout to get an idea of how to group your keywords.

Modify your keyword match type

Once you've segmented your keyword performance data by search terms match type, you can identify which match types are working well for which keywords and searches, you can refine match types for all your keywords to better hone in on the right customers.

Use filters to improve your keywords

Filters are a quick way to sort your keyword performance data and identify low-performing keywords. You can filter your keyword data by Status to see which keywords have low search volume, or maybe those that aren't showing your ads because they've been disapproved. Then, you can change your keyword with low search volume to a more general variation to help increase your traffic. Or, follow our advertising policies to fix any disapproved keywords. Here are some other filters you can use to see poor-performing keywords:

• Try using the Quality Score filter to see which keywords have a low Quality Score. For example, you can choose to see keywords with a Quality Score less than 3. Then, you can make changes to your keywords, such as making them more relevant to your ads or landing page, to help improve their Quality Scores.
• Filter your keywords by clickthrough rate (CTR) to see which keywords get you a lot of impressions, but few clicks. For example, you can filter keywords with a clickthrough rate that's less than 1%, and then make changes to those keywords so they're more relevant to your ads.
• Filter your keywords to see which ones are below your first page bid estimate. Then, you can increase the cost-per-click (CPC) bids for keywords that aren't showing ads on the first page of Google search results based on your first page bid estimate. Try using automated rules to automatically raise your keyword bids when they are below your first page bid estimate.
