Generate keyword ideas

  • The KeywordPlanIdeaService can be used to find new keywords and historical metrics for Google Search campaigns.

  • Keyword ideas can be generated using keywords, a URL, or both as seeds.

  • Targeting parameters such as location, language, and network settings can be used to refine keyword idea generation.

  • Historical statistics like search volume data are provided with the results to help determine keyword usability.

  • This service offers similar functionality to the Keyword Planner tool in the Google Ads UI.

Using the KeywordPlanIdeaService, you can discover keyword suggestions that are relevant to your Google Search campaign, or retrieve historical metrics for an existing list of 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. The service returns historical statistics, such as search volume data, to help you decide whether to use the keywords in 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 keyword ideas:

  • For words or phrases that describe what you're advertising, use KeywordSeed (requires at least 1 and up to 20 keywords). This can be a general type of business you are targeting, such as plumbers, or 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 service does not use the contents of hyperlinks to generate keyword ideas.

  • For both keyword seeds and URL seeds, use KeywordAndUrlSeed (requires 1 to 20 keywords along with a URL).

    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 configure language, location (up to 10 geo_target_constants), keyword_plan_network, include_adult_keywords, keyword_annotation (Refine keywords), and historical_metrics_options.

The response supports pagination (up to 10,000 results per page; always check next_page_token to determine if additional pages are available, as a page might return fewer than page_size results before the final page). Each GenerateKeywordIdeaResult returns the canonical text (with close_variants), historical keyword_idea_metrics for filtering before generating forecast metrics, and optional keyword_annotations.

Request and response field reference

Call KeywordPlanIdeaService.GenerateKeywordIdeas at the following endpoint:

POST https://googleads.googleapis.com/v26/customers/{customer_id}:generateKeywordIdeas

The following table summarizes the fields and constraints on GenerateKeywordIdeasRequest:

Request field Requirement Format and constraints
customer_id Required 10-digit customer ID (string) without hyphens.
seed (oneof) Required Specify one of:
• keyword_seed: keywords[] (1 to 20 strings).
• url_seed: url (specific page URL).
• keyword_and_url_seed: url plus 1 to 20 keywords[].
• site_seed: site (domain name such as www.example.com, returning up to 250,000 ideas).
language Optional Language criterion resource name (languageConstants/{criterion_id}, for example, languageConstants/1000 for English). See Language Constants. If omitted, keywords across all languages are included.
geo_target_constants[] Optional Up to 10 location resource names (geoTargetConstants/{criterion_id}, for example, geoTargetConstants/2840 for the United States). See Geo Targets. An empty list targets all geographies.
keyword_plan_network Optional KeywordPlanNetwork (GOOGLE_SEARCH or GOOGLE_SEARCH_AND_PARTNERS). Defaults to GOOGLE_SEARCH_AND_PARTNERS.
include_adult_keywords Optional bool controlling whether adult keywords are returned. Defaults to false.
keyword_annotation[] Optional List of KeywordPlanKeywordAnnotation values (such as KEYWORD_CONCEPT) to populate keyword_annotations on each result.
aggregate_metrics Optional KeywordPlanAggregateMetrics with aggregate_metric_types set to DEVICE to return device-segmented search counts in aggregate_metric_results.
historical_metrics_options Optional HistoricalMetricsOptions specifying an optional year_month_range (available for the past 4 years; defaults to the past 12 months) and include_average_cpc.
page_size and page_token Optional Maximum results per page (int32, up to 10,000) and continuation token from next_page_token. Keep all other request fields identical across paginated requests.

The GenerateKeywordIdeaResponse message returns the following fields:

Response field Type Description
results[].text string Canonical keyword idea text representing the suggestion and its combined close_variants[].
results[].close_variants[] string[] Close variants combined into this GenerateKeywordIdeaResult.
results[].keyword_idea_metrics KeywordPlanHistoricalMetrics Search volume: avg_monthly_searches (12-month average) and monthly_search_volumes[] (year, month, monthly_searches).
Competition: competition (LOW, MEDIUM, HIGH) and competition_index (0 to 100).
Bids & CPC: low_top_of_page_bid_micros (20th percentile), high_top_of_page_bid_micros (80th percentile), and average_cpc_micros (populated when include_average_cpc = true).
results[].keyword_annotations KeywordAnnotations Populated when KEYWORD_CONCEPT is requested in keyword_annotation; contains concepts[] (name, concept_group.name, and concept_group.type).
aggregate_metric_results KeywordPlanAggregateMetricResults Populated when DEVICE is requested in aggregate_metrics; contains device_searches[] (MOBILE, TABLET, DESKTOP).
next_page_token and total_size string, int64 Continuation token for the next page (omitted on the last page) and total count of available keyword ideas.
