Keyword Ideas

Using the KeywordPlanIdeaService, you can search for new keywords that are relevant to your Google Search campaign, or find historical metrics on keywords.

Generate ideas

Generate keyword ideas for a campaign with KeywordPlanIdeaService.GenerateKeywordIdeas.

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 are returned to help you determine if you want to use the keywords for your campaign. For users familiar with the Google Ads UI, this is similar to Keyword Planner.

There are several 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 URL seeds, the contents of hyperlinks are not used to generate keyword ideas.

  • For both keyword seeds and a URL seeds, use KeywordAndUrlSeed.

    Using KeywordAndUrlSeed can result in a larger volume of keyword ideas, as compared to just UrlSeed.

  • For an entire site, use SiteSeed. Given a top-level domain name, such as www.example.com, the site seed generates up to 250,000 keyword ideas from publicly available information.

To narrow down your targeting, you can:

The result set in the response supports pagination.

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.
