Set for a single stream

gtag('config', 'STREAM_ID', {
  'campaign_id': 'abc.123'
});

campaign_medium

Use campaign_medium to identify a medium such as email or cost-per-click.

Example

gtag('set', 'campaign_medium', 'cpc');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'campaign_medium': 'cpc'
});

campaign_name

Used for keyword analysis. Use campaign_name to identify a specific product promotion or strategic campaign.

Example

Set globally

gtag('set', 'campaign_name', 'spring_sale');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'campaign_name': 'spring_sale'
});

campaign_source

Use campaign_source to identify a search engine, newsletter name, or other source.

Example

Set globally

gtag('set', 'campaign_source', 'google');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'campaign_source': 'google'
});

campaign_term

Example

Set globally

gtag('set', 'campaign_term', 'running+shoes');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'campaign_term': 'running+shoes'
});

campaign

An object containing all campaign values that can be set.

The campaign object is provided to support legacy implementations, and is not recommended for most cases. Instead, you should use the campaign-prefixed version of each field:

• campaign_id
• campaign_source
• campaign_medium
• campaign_name
• campaign_term
• campaign_content

Example

Set globally

gtag('set', 'campaign', {
  'id': 'abc.123',
  'source': 'google',
  'medium': 'cpc',
  'name': 'spring_sale',
  'term': 'running+shoes',
  'content': 'logolink'
});

Set for a single stream

gtag('config', 'STREAM_ID', {
  'campaign': {
    'id': 'abc.123',
    'source': 'google',
    'medium': 'cpc',
    'name': 'spring_sale',
    'term': 'running+shoes',
    'content': 'logolink'
  }
});

client_id

Pseudonymously identifies a browser instance. By default, this value is stored as part of the first-party Analytics cookie with a two-year expiration.

Example

Set globally

gtag('set', 'client_id', 'aaa.bbb');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'client_id': 'aaa.bbb'
});

content_group

Example

Set globally

gtag('set', 'content_group', '/news/sports');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'content_group': '/news/sports'
});

cookie_domain

Specifies the domain used to store the analytics cookie.

Set to 'none' to set the cookie without specifying a domain.

Set to 'auto' (the default value) to set the cookie to the top level domain plus one subdomain (eTLD +1). For example if cookie_domain is set to 'auto' https://example.com would use example.com for the domain, and https://subdomain.example.com would also use example.com for the domain.

Example

Set globally

gtag('set', 'cookie_domain', 'example.com');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'cookie_domain': 'example.com'
});

cookie_expires

Every time a hit is sent to Google Analytics, the cookie expiration time is updated to be the current time plus the value of the cookie_expires field. This means that if you use the default value time of two years (63072000 seconds), and a user visits your site every month, their cookie will never expire.

If you set the cookie_expires time to 0 (zero) seconds, the cookie turns into a session based cookie and expires once the current browser session ends.

Example

Set globally

gtag('set', 'cookie_expires', 28 * 24 * 60 * 60 /* 28 days, in seconds */);

Set for a single stream

gtag('config', 'STREAM_ID', {
  'cookie_expires': 28 * 24 * 60 * 60 /* 28 days, in seconds */
});

cookie_flags

Appends additional flags to the cookie when set. Flags must be separated by semicolons. See write a new cookie for some examples of flags to set.

Example

Set globally

gtag('set', 'cookie_flags', 'SameSite=None;Secure');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'cookie_flags': 'SameSite=None;Secure'
});

cookie_path

Specifies the subpath used to store the analytics cookie.

Example

Set globally

gtag('set', 'cookie_path', '/example_path');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'cookie_path': '/example_path'
});

cookie_prefix

Specifies a prefix to prepend to analytics cookie names.

Example

Set globally

gtag('set', 'cookie_prefix', 'prefix');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'cookie_prefix': 'prefix'
});

cookie_update

When cookie_update is set to true, gtag.js will update cookies on each page load. This will update the cookie expiration to be set relative to the most recent visit to the site. For example, if cookie expiration is set to one week, and a user visits using the same browser every five days, the cookie expiration will be updated on each visit and will effectively never expire.

When set to false, cookies are not updated on each page load. This has the effect of cookie expiration being relative to the first time a user visited the site.

Example

Set globally

gtag('set', 'cookie_update', true);

Set for a single stream

gtag('config', 'STREAM_ID', {
  'cookie_update': true
});

ignore_referrer

Set to true to indicate to Analytics that the referrer shouldn't be displayed as a traffic source. Learn when to use this field

Example

Set globally

gtag('set', 'ignore_referrer', true);

Set for a single stream

gtag('config', 'STREAM_ID', {
  'ignore_referrer': true
});

language

Specifies the language preference of the user. Defaults to the user's navigator.language value.

Example

Set globally

gtag('set', 'language', 'en-us');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'language': 'en-us'
});

page_location

Specifies the full URL of the page. Defaults to the user's document.location value.

Example

Set globally

gtag('set', 'page_location', 'https://example.com/page1');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'page_location': 'https://example.com/page1'
});

page_referrer

Specifies which referral source brought traffic to a page. This value is also used to compute the traffic source. The format of this value is a URL. Defaults to the user's document.referrer value.

Example

Set globally

gtag('set', 'page_referrer', 'https://example.com');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'page_referrer': 'https://example.com'
});

page_title

The title of the page or document. Defaults to the user's document.title value.

Example

Set globally

gtag('set', 'page_title', 'Settings');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'page_title': 'Settings'
});

send_page_view

Set to false to prevent the default snippet from sending a page_view.

Example

Set globally

gtag('set', 'send_page_view', false);

Set for a single stream

gtag('config', 'STREAM_ID', {
  'send_page_view': false
});

screen_resolution

Specifies the resolution of the screen. Should be two positive integers separated by an x. For example, for an 800px by 600px screen, the value would be 800x600. Calculated from the user's window.screen value.

Example

Set globally

gtag('set', 'screen_resolution', '800x600');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'screen_resolution': '800x600'
});

user_id

Specifies a known identifier for a user provided by the site owner/library user. It must not itself be PII (personally identifiable information). The value should never be persisted in Google Analytics cookies or other Analytics provided storage.

Example

Set globally

gtag('set', 'user_id', 'id');

Set for a single stream

gtag('config', 'STREAM_ID', {
  'user_id': 'id'
});

user_properties

User properties are attributes that can be used to describe segments of your user base, such as language preference or geographic location. Up to 25 additional user properties can be set per project.

Example

Set globally

gtag('set', 'user_properties', {
  'favorite_color': 'blue'
});

Set for a single stream

gtag('config', 'STREAM_ID', {
  'user_properties': {
    'favorite_color': 'blue'
  }
});
