Paste your landing page and a list of creators, and get one tagged link per creator in bulk. Each link carries utm_source, utm_medium and utm_campaign, with the creator's name so your analytics can tell them apart.
The prefilled values are placeholders, so replace them. Settings are saved in the page URL. Nothing leaves your browser.
UTM values are case sensitive, so lowercase avoids split rows.
3 links built. Test one in your analytics before you brief creators.

| mike.lifts | tiktok | https://yourstore.com/products/your-product?utm_source=tiktok&utm_medium=influencer&utm_campaign=spring-gifting&utm_content=mike.lifts |
| alex_cooks | youtube | https://yourstore.com/products/your-product?utm_source=youtube&utm_medium=influencer&utm_campaign=spring-gifting&utm_content=alex_cooks |
Seed turns one branded link into a $0 draft order for each gift. Tag the links your creators post with this builder and you have the order and the click side by side.
Install Seed on ShopifyPick a convention once and never improvise, because every misspelling becomes its own row in your reports. Google's UTM guidance says values are case sensitive and recommends lowercase. A workable starting scheme:
| Parameter | What it holds | Example |
|---|---|---|
| utm_source | The platform the link is posted on | |
| utm_medium | The channel type, the same for every creator link | influencer |
| utm_campaign | The campaign or gifting wave | spring-gifting |
| utm_content | The creator, so you can compare within a campaign | sarah_runs |
| utm_id (optional) | A campaign ID matching your own records | sg-2026-03 |
Use hyphens or underscores instead of spaces. Pair these links with a per-creator discount code from the bulk discount code generator to get two signals for the same sale, then compare them in the promo code attribution calculator. Keep the link list in your influencer tracking spreadsheet.
Google Analytics says to always use utm_source, utm_medium and utm_campaign, and missing parameters show up as (not set) in reports. For influencers, add the creator's handle in utm_content so you can compare creators inside one campaign. utm_id is optional but recommended by Google.
Yes. Google's documentation says utm_source=google and utm_source=Google are different values, and recommends sticking to lowercase. This builder lowercases everything by default so Sarah and sarah do not split into two rows in your reports. You can turn that off if you need exact case.
Either works if you stay consistent. Putting the platform in utm_source and the creator in utm_content groups traffic by platform and lets you drill down by creator. Putting the creator in utm_source makes each creator a top-level source. This tool supports both, plus utm_term.
A tagged link is a normal URL with extra parameters, so you can paste it anywhere a link is allowed, including link-in-bio tools. Some platforms wrap or shorten links and a few strip parameters, so click through a test link and check it in your analytics before you brief creators.
Links are built in your browser with the standard URL API, so existing query parameters on your landing page are kept and values are percent-encoded. Creator names are stripped of the leading @, spaces become hyphens, and anything other than letters, digits, hyphen, underscore and dot is dropped. Parameter definitions come from Google Analytics Help: Collect campaign data with custom URLs. This tool does not check that your analytics receives the tags, so test a link first.
