Important: Google will sunset Universal Analytics (UA) on 1st July 2023 and replace it with Google Analytics 4 (GA4).
You must migrate your Universal Analytics property settings to Google Analytics 4 to avoid losing data.
This article explains how to use custom filters for the current visitor gauge and current visitor map widgets exclusively. If you’re setting up any other Google Analytics widget, please check this other article instead.
Custom filters are short statements that you can apply to Geckoboard's Google Analytics widgets to refine the data that’s displayed and drill down to the particular metric you're interested in.
From a technical perspective, custom filters restrict the rows of data that are – or aren't – included in the result. Each row in the result is tested against the filter: if the filter matches, the row is retained and if it doesn't match, the row is dropped.
Syntax of custom filters
The syntax of custom filters is always the same:
name operator expression
Filter names
For Real-Time Reporting, the name always begin with rt: followed by the dimension or metric you want to filter by. All the dimensions and metrics available through the Real-Time Reporting API are listed in Google's documentation .
Popular dimensions and metrics include:
campaign
pageTitle
referralPath
browser
source
pagePath
minutesAgo
country
region
city
mobileDeviceModel
eventAction
Filter operators
There are six filter operators for dimensions and six filter operators for metrics. The operators must be URL-encoded in order to be included in URL query strings.
Tip: Use the Data Feed Query Explorer to design filters that need URL encoding, since the Query Explorer automatically encodes URLS containing strings and spaces.
Operator | Description |
== | Equals |
!= | Does not equal |
> | Greater than |
< | Less than |
>= | Greater than or equal to |
<= | Less than or equal to |
Dimension Filters
Operator | Description |
== | Exact match |
!= | Does not match |
=@ | Contains substring |
!@ | Does not contain substring |
=~ | Contains a match for the regular expression |
!~ | Does not match regular expression |
Filter expressions
The expression states the values to be included in or excluded from the results.
There are a few important rules for filter expressions:
URL-reserved characters — Characters such as
&must be url-encoded in the usual way.Reserved characters — The semicolon and comma must be backslash escaped when they appear in an expression:
semicolon
\;comma
\,
Regular Expressions — You can also use regular expressions in filter expressions using the
=~and!~operators. Their syntax is similar to Perl regular expressions and have these additional rules:Maximum length of 128 characters — Regular expressions longer than 128 characters result in a
400 Bad Requeststatus code returned from the server.Case sensitivity — Regular expression matching is case-insensitive.
Example of a custom filter statement
rt:source==twitter
Where rt:source is the name of the filter expressed as rt: and the specific dimension you want to filter by (in this case source), the operator is how you want the dimension to be compared (==means Equals), and finallytwitteris the expression that contains the value for the comparison.
When applied to a Google Analytics widget (such as the current visitor map), this custom filter will include only results where the source is Twitter (and results from any other source will be filtered out).
Combining custom filters
Filters can be combined using OR and AND boolean logic to create a very specific set of data within a metric.
OR
The OR operator is defined using a comma (,). It takes precedence over the AND operator and may NOT be used to combine dimensions and metrics in the same expression.
Examples: (each must be URL encoded)
Country is either (United States OR Canada):
rt:country==United%20States,rt:country==Canada
Firefox users on (Windows OR Macintosh) operating systems:
rt:browser==Firefox;rt:operatingSystem==Windows,rt:operatingSystem==Macintosh
AND
The AND operator is defined using a semi-colon (;). It is preceded by the OR operator and CAN be used to combine dimensions and metrics in the same expression.
Example of custom filters combined:
Country is United States AND the browser is Firefox:
rt:country==United%20States;rt:browser==Firefox
Operating system is (Windows OR Macintosh) AND browser is (Firefox OR Chrome):
rt:operatingSystem==Windows,rt:operatingSystem==Macintosh;rt:browser==Firefox,rt:browser==Chrome
Country is United States AND hit occurred less than 5 minutes ago:
rt:country==United%20States;rt:minutesAgo<5
