Paging through results

Page Summary

• Google Ads API v19 and later use a fixed page size of 10,000 rows, and the page_size field is removed and cannot be set.

• GoogleAdsService.Search splits results into multiple responses, each containing 10,000 objects.

• To retrieve subsequent pages of results, you need to send the request again, updating the page_token with the next_page_token from the previous response.

• Client libraries automatically handle paging, while REST users must explicitly request each new page.

• The Google Ads API caches the entire dataset internally, making subsequent requests faster, provided the query remains exactly the same.

• For manual paging needs, retrieve and store results locally to build custom pagination logic.

You can page through results retrieved with GoogleAdsService.Search instead of downloading the entire result set at once. For an overview of reporting with Google Ads API, check out the Reporting guide.

Results are returned in pages of up to 10,000 rows. If page_size in the request is not set, it defaults to 10,000. If page_size is set to a value greater than 10,000, it still uses 10,000.

As an example, consider the following query:

SELECT
  ad_group.id,
  ad_group_criterion.type,
  ad_group_criterion.criterion_id,
  ad_group_criterion.keyword.text,
  ad_group_criterion.keyword.match_type
FROM ad_group_criterion
WHERE ad_group_criterion.type = KEYWORD

If your account contains 50,000 keywords, the result set will contain 10,000 GoogleAdsRow objects in the first response, along with a next_page_token.

To retrieve the next 10,000 rows, send the request again, but update the request's page_token to the response's next_page_token. Note that next_page_token is not populated in the response that contains the last batch of rows.

Our client libraries handle paging automatically. You only have to iterate through the rows of the response. When all rows in the current page have been returned, the client library fetches a new page of rows automatically on your behalf until the entire dataset is retrieved. If using REST instead of gRPC, you must explicitly make a request for each new page.

The Google Ads API internally caches the entire dataset, so subsequent requests are faster than the initial one.

Your query must remain exactly the same in subsequent requests to take advantage of the cached data. The requests won't contribute towards your quota, particularly for Explorer Access level and Basic Access level. If the query differs and is sent along with the same page token, an error is returned.

Key Point: If you need manual paging, such as for custom web pagination, we recommend that you retrieve and store the results locally, such as in a database, and build your own pagination logic.
