Outcomes to ad platforms

What Subcontext sends to Google Ads and Meta about the people who clicked your ads, how they're matched, and what to tell your customers.

Ad platforms look for more people like the conversions you report. If you only report form fills, they look for more people who fill in forms. Subcontext reports which of the people who clicked your ads went on to book, be quoted, buy, or pay commission, so the platforms can look for more of those.

This page is for whoever runs your ad accounts or answers questions about your privacy notice. To connect an account, see Built-in integrations; the dashboard help article Sending outcomes to Google Ads and Meta covers the settings.

What can be sent#

Each step from visit to sale is switched on separately on the connection:

Step When it happens Meta's event name, unless you change it Value
Engaged The visitor sent a first message, or answered a first form question Contact None
Conversing Three messages, or three form answers Conversing (a custom event) None
Lead They gave an email address or phone number, or submitted their details Lead None
Booked They made an appointment Schedule None
Quoted They were first quoted InitiateCheckout None
Sold They bought a policy Purchase The annual premium, in pounds

For Google Ads, you choose a conversion action for each step instead of an event name. Send the deepest step you have enough of to bid on (often Sold or Quoted), and treat the others as secondary. Otherwise bidding optimises for people who chat but don't buy.

You can also send any other outcome your firm records, such as Commission paid. On the connection, under Outcomes sent as conversions, choose the outcome, its Google Ads conversion action or Meta event name, and the money measure to use as its value.

Who is sent#

Only people who came from your own ads:

  • With a click id. When a visitor arrives from an ad, Subcontext stores the click id from the address: gclid, gbraid or wbraid for Google, and fbclid for Meta. A conversion is sent against that click, or against the click the person first arrived on, as long as the platform still credits it (90 days for both). The embeds also send a click remembered from an earlier page on your website, or found in your Meta pixel's or Google tag's cookies, with the time it was first seen; the 90 days count from then. See Ad clicks across pages.
  • Without a click id, only for outcomes, and only with enhanced matching turned on: a lead who came from that platform's paid traffic but whose click id wasn't kept is sent on their hashed email address and phone number instead.

A Meta _fbp cookie on its own never causes a conversion to be sent: the pixel sets it for every visitor, ad or not. It only helps Meta match a conversion that is sent anyway.

What each conversion contains#

Google Ads (offline click conversions):

Field Value
conversionAction The conversion action you chose.
gclid, gbraid or wbraid The click id, when there is one.
conversionDateTime When the step or outcome happened.
orderId Subcontext's own reference for this conversion, so it's never counted twice.
conversionValue, currencyCode The value and currency, when there is a value.
userIdentifiers Only with enhanced matching: the SHA-256 hash of the email address (trimmed, lower case) and of the phone number (digits and + only).

Meta (Conversions API, to your Pixel):

Field Value
event_name The step's event name, or the one you chose.
event_time When it happened.
event_id Subcontext's own reference, so a retry is counted once.
action_source website when there's a click id, system_generated when matched on email and phone alone.
event_source_url The page the person arrived on.
user_data.fbc Your Meta pixel's _fbc cookie, as the visitor's browser had it, when it carries the click being sent. Otherwise built from the fbclid and when the click was first seen. Only with a click id.
user_data.fbp Your Meta pixel's _fbp cookie (Meta's id for the browser), when your website has the pixel. Sent with any conversion that is sent, with or without a click id.
user_data.client_user_agent The person's browser, from their visit.
user_data.em, user_data.ph Only with enhanced matching: the SHA-256 hash of the email address (trimmed, lower case) and of the phone number (digits only).
custom_data.value, custom_data.currency The value and currency, when there is a value.

The email address and phone number are never sent unhashed. If your website also fires the same event from the Meta Pixel in the browser, Meta counts it twice, because the two events have different ids: send each event one way only.

Time limits and corrections#

  • Google Ads takes conversions up to 90 days old. A reversed outcome is retracted, an outcome whose value arrives later is updated, and a cancelled sale's conversion is retracted while Google still takes changes to it.
  • Meta takes conversions up to 7 days old; older ones are skipped. It can't take a conversion back, so a reversed or cancelled sale stays sent.

Failed sends are retried up to 5 times. If the platform rejects the sign-in, the connection is marked as needing to be connected again and your managers are told. For Meta that includes its "invalid or expired access token" answer (error code 190), which arrives as a 400 rather than a 401.

  • Subcontext sends conversions for people who clicked your ads. It doesn't check each person's marketing consent before sending, so your privacy notice needs to say that you share what happened after an ad click with the ad platform to measure your advertising.
  • Enhanced matching is off until a manager turns it on. It sends hashed email addresses and phone numbers, which the platforms match against their own users. Turn it on only if your privacy notice covers it.
  • Hashing hides the details in transit, but the platforms can still match them to an account. Treat it as sharing personal data.
  • Meta's and Google's own terms for these features (Google's customer data policies, Meta's Business Tools terms) apply to your account.
