Generate Keyword Ideas

Search for new keywords that are relevant to your Google Search campaign. You can provide keyword and URL seeds to generate ideas. Set targeting parameters such as locations, language, and network settings to narrow down your search. Historical statistics such as search volume data for these keywords are returned, so you can determine if you want to use the keyword for your campaign. For users familiar with the Google Ads UI, this is similar to Keyword Planner.

Generating ideas

Generate keyword ideas for a campaign with KeywordPlanIdeaService.GenerateKeywordIdeas.

There are a couple of ways you can create seeds for generating new keywords:

  • For words or phrases that describe what you're advertising, use KeywordSeed. This could be a general type of business you are targeting such as plumbers, or it could be a product or service you offer such as drain cleaning.
  • For the URL of a webpage or entire website related to your business, use UrlSeed. The URL seed targets only a specific URL. If there are no hits, the search automatically expands up to the pages from the same domain.
  • For both keyword seeds and a URL seeds, use KeywordAndUrlSeed.

To narrow down your targeting, you can set the language, location, and network in the GenerateKeywordIdeasRequest.

Ideas are returned with historical metrics which can be used to filter a list down to use with forecasts. For example, you might only want to target high search volumes to maximize the reach of your campaign, or you might want to target only higher competition scores to boost your awareness.

Migrating from the AdWords API

KeywordPlanIdeaService.GenerateKeywordIdeas replaces AdWords API's TargetingIdeaService.get with RequestType=IDEAS. These keywords can be added to your Keyword Plans for forecasting or obtaining overall historical metrics for your plan. A key difference is that the API no longer returns the original seed keywords in the ideas list. This means that if you were using this to get historical metrics for an existing list of keywords, you'll need to set up a KeywordPlan.

Mapping to the UI

KeywordPlanIdeaService.GenerateKeywordIdeas has similar functionality in the UI's Keyword Planner.
