Metrics

ga:pageLoadTime

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

Data type: integer.

ga:pageLoadSample

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

Data type: integer.

ga:avgPageLoadTime

Average time in seconds spent to load the page, from the moment of referral to the page fully loading in the 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 processing requests to the DNS server while 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 taken to load the page.

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

Data type: float.

ga:redirectionTime

Time in milliseconds taken to process the HTTP redirect while loading the page. If there was no HTTP redirect, the value of this metric will be 0.

Data type: integer.

ga:avgRedirectionTime

Average time in milliseconds spent processing the HTTP redirect while loading the page. If the HTTP redirect couldn't be processes, 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 while getting the page content.

Network delays and site load 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, page size, 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 the browsers requires to process the document object model (DOM), including 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.
