Metrics

ga:pageLoadTime

Time in milliseconds from the moment of referral to complete loading of the page in the browser.

Data type: integer.

ga:pageLoadSample

Number of pages that were used to calculate average page load time.

Data type: integer.

ga:avgPageLoadTime

Average time in seconds spent to load the page, from the moment of referral until the page is fully loaded in the user's  browser.

Calculation formula: (ga:pageLoadTime / ga:pageLoadSample / 1000).

Data type: float.

ga:domainLookupTime

Time in milliseconds spent processing requests to the DNS server while loading the page.

Data type: integer.

ga:avgDomainLookupTime

Average time, in seconds, spent to process queries to the DNS server when loading the page.

Calculation formula: (ga:domainLookupTime / ga:speedMetricsSample / 1000).

Data type: float.

ga:pageDownloadTime

Time in milliseconds taken to load the page.

Data type: integer.

ga:avgPageDownloadTime

Average time, in seconds, spent to load the page.

Calculation formula: (ga:pageDownloadTime / ga:speedMetricsSample / 1000).

Data type: float.

ga:redirectionTime

Time in milliseconds spent processing HTTP redirects while loading the page. If HTTP redirects were not performed, the value of this metric will be equal to 0.

Data type: integer.

ga:avgRedirectionTime

Average time in milliseconds spent processing HTTP-redirect while loading the page. If HTTP-redirect was not installed, the value of this metric will be 0.

Data type: float.

ga:serverConnectionTime

Time in milliseconds that the browser waited to connect to the HTTP-server during the retrieval of page content.

Network delays and site traffic levels affect this parameter.

Data type: integer.

ga:avgServerConnectionTime

Average time in seconds spent on establishing a TCP connection for this page.

Calculation formula: (ga:serverConnectionTime / ga:speedMetricsSample / 1000).

Data type:float.

ga:serverResponseTime

Time in milliseconds during which a response with page content is sent from the HTTP server to the browser.

The web server's response generation speed, the size of the page, and the bandwidth speed between the user and the web server affect this parameter.

Data type: integer.

ga:avgServerResponseTime

Average time in seconds that it takes to transmit a response with the page content from the HTTP-server to the browser.

Calculation formula: (ga:serverResponseTime / ga:speedMetricsSample / 1000).

Data type: float.

ga:speedMetricsSample

This metric is used to calculate the average site speed. For example, ga:avgDomainLookupTime, ga:avgPageDownloadTime, ga:avgRedirectionTime, ga:avgServerConnectionTime and ga:avgServerResponseTime.

Data type: integer.

ga:domInteractiveTime

Time in milliseconds the browser requires to process the document object model (DOM), including time spent connecting the user to the server.

Data type: integer.

ga:avgDomInteractiveTime

Average time in seconds required for the browser to process a Document Object Model (DOM), include time spent connecting the user to the server.

Calculation formula: (ga:domInteractiveTime / ga:domLatencyMetricsSample / 1000).

Data type: float.

ga:domLatencyMetricsSample

This metric is used to calculate the average DOM processing speed. For example, ga:avgDomInteractiveTime.

Data type: integer.
