Facebook, TikTok & Google Ads URL parameters builder
Pick a traffic source, tick the fields your tracker needs and choose how to name them. You get the string for the platform's URL parameters field and, once you paste your tracker link, the full URL with every macro still readable.
Result
Parameter string
Paste into the ad's URL parameters field, without a leading ?.
campaign_id={{campaign.id}}&adset_id={{adset.id}}&ad_id={{ad.id}}&sub1={{placement}}&sub2={{site_source_name}}Full URL
https://go.example.com/?campaign_id={{campaign.id}}&adset_id={{adset.id}}&ad_id={{ad.id}}&sub1={{placement}}&sub2={{site_source_name}}- Warning The link uses http://, so browsers mark the landing as not secure. Switch to https:// if your domain has a certificate.
- Note
- Note Encoded braces (%7B %7D) in the base URL were turned back into { } so the macros stay readable.
Where to paste it
Each platform swaps its macros for real values at click time, but only in its own field and its own syntax.
Facebook / Meta Ads
At ad level, in the URL parameters field. Paste the string without a leading ?; the website URL stays clean. App promotion has no separate field: add the parameters to the end of the deferred deep link. Dynamic parameters don't work in collection ads on Instagram placements.
TikTok Ads
Ad details → Destination URL. Paste the full URL, or click Edit under Preview → Build URL parameters and add keys under Custom parameters. With Auto-attach on, TikTok adds its own UTMs (source TikTok, medium Paid, plus an ID and a name), so check the preview for any key set twice.
Google Ads
Final URL suffix at account, campaign, ad group or ad level (in the ad, under Ad URL options), without a leading ?. If a tracker redirect sits in the tracking template, start it with {lpurl}: when {lpurl} isn't at the beginning, Google escapes the final URL.

Where it breaks
- 1
A macro arrives as plain text
{{ad.id}} works only on Meta, __CID__ only on TikTok, {creative} only on Google. A literal macro in the click log means the syntax or the placement is wrong: Meta skips collection ads on Instagram, {keyword} is blank in Performance Max, and Demand Gen doesn't support {placement}, {keyword} or {network}.
- 2
UTMs where the tracker needs subs
UTMs feed analytics. Routing, click lookup and postbacks need the tracker's own fields. If Auto-attach or the base link already sets a key, it arrives twice and each system may keep a different value.
- 3
Double encoding
Macros must reach the ad platform exactly as typed. Run the string through a URL encoder and {{ad.id}} becomes %7B%7Bad.id%7D%7D, so the platform no longer sees a macro to replace. Encode an already encoded value and %20 turns into %2520.
- 4
Names instead of IDs
Name macros expand to the full name with spaces as %20, so the link grows with every level. Meta also freezes names at first publish: rename the campaign and the old name keeps arriving. Join reports on IDs and keep names as labels.
Keep the click context all the way to the deposit.
DarkCore captures campaign IDs, sub1–sub10 and fbclid or ttclid on the first click, passes them into the offer link and ties the postback back to the same click.
