Telemetry
=========
This section describes existing telemetry probes measuring interaction with
search engines from the browser UI.
This document only covers Legacy telemetry, not Glean telemetry.
Glean metrics are self-documenting and can be looked up in the Glean dictionary.
Other search-related telemetry is recorded by Toolkit such as search service
telemetry and telemetry related to fetching search suggestions. Toolkit search
telemetry is relevant to Firefox as well as other consumers of Toolkit. See
:doc:`/toolkit/search/Telemetry` in the Toolkit documentation for details.

Glossary
--------
SAP
Search Access Point, a search that a user performs by visiting
via one of Firefox's access points. The search may or may not have an
associated partner code.
SERP
A search engine results page.
Persisted Search
When a user has the following preference values (only applies
when the search bar isn't present in any toolbar or overflow panel):
- ``browser.urlbar.showSearchTerms.enabled``: ``true``
- ``browser.urlbar.showSearchTerms.featureGate``: ``true``
and does the following:
- Starts a search from the urlbar or context menu.
- Loads the default search engine results page.
the search term will persist in the Urlbar, causing it to enter a Persisted Search state.
.. _serp-definitions:
Definitions
-----------
``organic``
A search that a user performs by visiting a search engine directly.
``tagged``
Refers to a page that is tagged with an associated partner code.
It may or may not have originated via a SAP.
``tagged-follow-on``
Refers to a page that is tagged with an associated partner code and has been identified
as a follow-on search. It may or may not have originated via a SAP.
Search probes relevant to front-end searches
--------------------------------------------
The Address Bar is an integral part of search and has `additional telemetry of its own`_.
BrowserSearchTelemetry.sys.mjs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This telemetry is handled by `BrowserSearchTelemetry.sys.mjs`_.
sap.counts
^^^^^^^^^^
See the `sap.counts Event documentation`_ for more information.
SEARCH_COUNTS - SAP usage
^^^^^^^^^^^^^^^^^^^^^^^^^
Note: This probe is reflected into the Glean probe ``sap.deprecated_counts``,
which should not be used for ongoing measurements. Use the new ``sap.counts``
event instead.
This histogram tracks search engines and Search Access Points. It is augmented
by multiple SAPs, including the urlbar.
It's a keyed histogram, the keys are strings made up of search engine names
and SAP names, for example ``google.urlbar``.
For each key, this records the count of searches made using that engine and SAP.
SAP names can be:
- ``alias`` This is when using an alias (like ``@google``) in the urlbar.
Note there is often confusion between the terms alias and keyword, and
they may be used inappropriately: aliases refer to search engines, while
keywords refer to bookmarks. We expect no results for this SAP in Firefox
83+, since urlbar-searchmode replaces it.
- ``abouthome``
- ``contextmenu``
- ``newtab``
- ``searchbar``
- ``system``
- ``urlbar`` Except aliases and search mode.
- ``urlbar-handoff`` Used when searching from about:newtab.
- ``urlbar-persisted`` Used when searching from the Urlbar while it
was in a Persisted Search state.
- ``urlbar-searchmode`` Used when the Urlbar is in search mode.
- ``webextension``
browser.engagement.navigation.*
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These keyed scalars track search through different SAPs, for example the
urlbar is tracked by ``browser.engagement.navigation.urlbar``.
It counts loads triggered in a subsession from the specified SAP, broken down
by the originating action.
Possible SAPs are:
- ``urlbar`` Except search mode.
- ``urlbar_handoff`` Used when searching from about:newtab.
- ``urlbar_persisted`` Used when searching from the Urlbar while it
was in a Persisted Search state.
- ``urlbar_searchmode`` Used when the Urlbar is in search mode.
- ``searchbar``
- ``about_home``
- ``about_newtab``
- ``contextmenu``
- ``webextension``
- ``system`` Indicates a search from the command line.
Recorded actions may be:
- ``search``
Used for any search from ``contextmenu``, ``system`` and ``webextension``.
- ``search_alias``
For ``urlbar``, indicates the user confirmed a search through an alias.
- ``search_enter``
For ``about_home`` and ``about:newtab`` this counts any search.
For the other SAPs it tracks typing and then pressing Enter.
- ``search_formhistory``
For ``urlbar``, indicates the user picked a form history result.
- ``search_oneoff``
For ``urlbar`` or ``searchbar``, indicates the user confirmed a search
using a one-off button.
- ``search_suggestion``
For ``urlbar`` or ``searchbar``, indicates the user confirmed a search
suggestion.
SearchSERPTelemetry.sys.mjs
~~~~~~~~~~~~~~~~~~~~~~~~~~~
This telemetry is handled by `SearchSERPTelemetry.sys.mjs and the associated parent/child actors`_.
browser.search.content.*
^^^^^^^^^^^^^^^^^^^^^^^^
These keyed scalars track counts of SERP page loads.
The key format is ``<provider>:[tagged|tagged-follow-on|organic]:[<code>|other|none]``.
The values in angled brackets will be replaced by real values based on the URL of the
SERP page. The key format is built from:
- ``<provider>`` The name of the provider. This is not linked to search engine
ids, as the search may have been generated organically.
- ``[tagged|tagged-follow-on|organic]`` The type of SERP load. See the
:ref:`definitions section above <serp-definitions>`.
- ``[<code>|other|none]`` Details of the code associated with the SERP load:
- ``<code>`` The partner code found in the URL. This is only for partners
associated with the product.
- ``other`` The SERP load had a partner code, but it is not recognised as
an associated partner or an organic code.
- ``none`` The SERP load had no partner codes, or it was a recognised organic code,
e.g. some sites assign their own codes for searches.
They are broken down by the originating SAP where known:
- ``urlbar`` Except search mode.
- ``urlbar_handoff`` Used when searching from about:newtab.
- ``urlbar_persisted`` Used when searching from the Urlbar while it
was in a Persisted Search state.
- ``urlbar_searchmode`` Used when the Urlbar is in search mode.
- ``searchbar``
- ``about_home``
- ``about_newtab``
- ``contextmenu``
- ``webextension``
- ``system`` Indicates a search from the command line.
- ``tabhistory`` Indicates a search was counted as a result of the user loading it from the tab history.
- ``reload`` Indicates a search was counted as a result of reloading the page.
- ``unknown`` Indicates the origin was unknown.
browser.search.withads.*
^^^^^^^^^^^^^^^^^^^^^^^^
These keyed scalar track counts of SERP pages with adverts displayed. The key
format is ``<provider>:<tagged|organic>``.
They are broken down by the originating SAP where known, the list of SAP
is the same as for ``browser.search.content.*``.
browser.search.adclicks.*
^^^^^^^^^^^^^^^^^^^^^^^^^
This is the same as ```browser.search.withads.*`` but tracks counts for them
clicks of adverts on SERP pages.
