What is a SubID?<\/h2><\/div>\n\n\n\n

A SubID<\/strong> is a custom tracking value you append to your affiliate link so you can identify which click<\/strong> (ad, page, placement, author, keyword, etc.) led to a conversion. Think of it as your label<\/strong> for the click\u2014saved by the network and returned in reports or postbacks.<\/p>\n\n\n\n

No extra setup, no messy URLs\u2014just precise insights and cleaner reports, right out of the box.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Definition & common synonyms<\/h3>\n\n\n\n

Different networks and trackers call the field by different names. They all serve the same purpose: carry your metadata through the click \u2192 conversion flow.<\/p>\n\n\n\n

Concept<\/th>Typical names you\u2019ll see<\/th><\/tr><\/thead>
Single free-form SubID<\/td>subid<\/code>, sub_id<\/code>, sub<\/code>, sid<\/code>, aff_sub<\/code><\/td><\/tr>
Multiple slots (granular)<\/td>sub1<\/code>, sub2<\/code>, sub3<\/code>, sub4<\/code>, sub5<\/code><\/td><\/tr>

You\u2019ll map your own labels (e.g., post<\/code>, placement<\/code>, creative<\/code>) into whichever parameter name the network expects.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Where it \u201clives\u201d (in the URL)<\/h3>\n\n\n\n

SubIDs are added as query parameters<\/strong> on your affiliate deeplink. They can be attached directly to a network link or inside a redirect\/url<\/code> parameter when the link wraps a destination URL.<\/p>\n\n\n\n

Direct example<\/strong><\/p>\n\n\n\n

https:\/\/track.network.com\/click?affid=12345&subid=review-page_top<\/strong><\/code><\/pre>\n\n\n\n
Wrapped\/redirect example<\/strong><\/p>\n\n\n\n
https:\/\/track.network.com\/click?affid=12345&subid=review-page_top<\/strong>\n  &url=https%3A%2F%2Fmerchant.com%2Fproduct%3Fsku%3DABC\n<\/code><\/pre>\n\n\n\n
Multi-slot example<\/strong><\/p>\n\n\n\n
https://example.hasoffers.com\/aff_c?offer_id=9&aff_id=101\n  &aff_sub=blog\n  &aff_sub2=airfryer_roundup\n  &aff_sub3=hero_block\n  &aff_sub4=creativeA\n  &aff_sub5=item123<\/strong>\n<\/code><\/pre>\n\n\n\n
<\/div>
\n
Rule of thumb: URL-encode<\/strong> values (especially if you pass spaces, slashes, or long strings) and keep them short, safe, and non-PII.<\/p>\n<\/div><\/div><\/div>\n\n\n\n
