This document describes the collection limits and quotas for all Google Analytics collection tags, libraries and SDKs.
Overview
Google Analytics is used by millions of sites. To protect the system from receiving more data than it can handle, and to ensure an equitable distribution of system resources, certain limits have been put in place. Our policies are as follows and are subject to change.
The following quotas and limits apply to all Google Analytics collection tags, libraries and SDKs. There are both property specific and client library specific limits.
Property Specific
These limits apply to the Web Property / Property / Tracking ID.
- 10 million hits per month per property
If you go over this limit, the Google Analytics team might contact you and ask you upgrade to Analytics 360 or implement client sampling to reduce the amount of data being sent to Google Analytics.
For monthly total Analytics 360 limits, please contact your account manager or service representative.
ga.js or Legacy Libraries
This applies to ga.js, mobile snippets, and any other legacy tracking library.
- 500 hits per session
If you go over this limit, additional hits will not be processed for that session. This limit applies to Analytics 360 as well.
Universal Analytics Enabled
This applies to analytics.js, Android iOS SDK, and the Measurement Protocol.
- 200,000 hits per user per day
- 500 hits per session
If you go over either of these limits, additional hits will not be processed for that session / day, respectively. These limits apply to Analytics 360 as well.
Timing hits
Additional limits are imposed on timing hits, including site speed hits that are automatically sent by ga.js and analytics.js. The maximum number of timing hits that will be processed per property per day is the greater of 10,000 or 1% of the total number of pageviews processed for that property that day. Additional limits apply to lower hit counts; those details are outlined in the User Timings developer guide.
Client Library / SDK Specific Rate Limits
Each client library implements a rate limiting mechanism that ensures you don't send too many hits at once. The mechanism is based on the token bucket algorithm, and allows you to send bursts of hits to Google Analytics, while preventing clients from sending data too quickly.
Each tracker has a maximum limit for the number of requests it can send concurrently. The tracker also maintains a count of the number of concurrent hits that have been sent. As a hit is sent to Google Analytics, the count decreases by one. When the count is 0, the maximum limit has been reached, and no new requests are sent. Then over a small period of time, the count is increased back to its original limit, allowing data to be sent again.
Here is a list describing how each library handles rate limits. If any of these limits are reached, hits will not be sent to Google Analytics servers, and the data will not be processed into reports. These limits apply to Analytics 360 as well.
ga.js:
Each ga.js tracker object starts with 10 hits that are replenished at a rate of 1 hit per second. Applies only to event type hits.
analytics.js:
Each analytics.js tracker object starts with 20 hits that are replenished at a rate of 2 hit per second. Applies to all hits except for ecommerce (item or transaction).
Android SDK
For each tracker instance on a device, each app instance starts with 60 hits that are replenished at a rate of 1 hit every 2 seconds. Applies to all hits except for ecommerce (item or transaction).
iOS SDK
Each property starts with 60 hits that are replenished at a rate of 1 hit every 2 seconds. Applies to all hits except for ecommerce (item or transaction).
