Bulk Link Creation
Bulk link creation is the process of generating many tracked links in one operation, from a spreadsheet or a set of parameter values, instead of building each link by hand. Each output link usually combines a destination URL with UTM parameters, and often a short link or QR code. Teams use it to launch campaigns that need dozens or hundreds of unique links on the same day.
How Bulk Link Creation Works
Bulk link creation tools accept one of two inputs and return a file of finished links.
- List mode (CSV): each row is one link. Columns hold the destination URL and the UTM values, and the tool maps each column to a parameter.
- Matrix mode: you enter lists of values (sources, mediums, campaigns) and the tool generates every combination for each destination URL.
A minimal list-mode input looks like this:
url,utm_source,utm_medium,utm_campaign,utm_content
https://www.example.com/shoes,facebook,cpc,fall-sale-2026,carousel-a
https://www.example.com/boots,facebook,cpc,fall-sale-2026,carousel-b
https://www.example.com/shoes,newsletter,email,fall-sale-2026,hero-button
The output is the same rows with a finished URL appended, for example:
https://www.example.com/shoes?utm_source=facebook&utm_medium=cpc&utm_campaign=fall-sale-2026&utm_content=carousel-a
Better tools add three steps around generation: validation against naming rules before any link is created, optional shortening of every link, and an export that records who ran the batch and when.
Matrix Mode Multiplies Fast
A parameter matrix creates links by multiplication, not addition. Three sources, two mediums, and four campaigns produce 3 × 2 × 4 = 24 links for each destination. Across 10 destination URLs, that is 240 links.
The catch is that a matrix does not know which pairings make sense. In the same example, the sources were facebook, linkedin, and email, and the mediums were cpc and social. Eight of the 24 combinations pair email with cpc or social, which describes traffic that never happens. Across 10 destinations, that is 80 links nobody should use, sitting in the same export as the real ones.
Prune impossible source and medium pairs before generating, or split the matrix into one run per channel. A link that exists will eventually get pasted somewhere, and a mislabeled click is harder to fix in a report than a missing link is to create.
Why Bulk Links Break
Most broken bulk links come from how the tool joins the destination URL and the tags, not from the tag values. A tool that pastes ?utm_source=... onto the end of every URL fails whenever the destination is not a plain path.
A reproducible test ran six common destination URL shapes through two builders: naive string concatenation and a query-aware builder (Python’s urllib.parse). Each result was then parsed the way a server reads a query string.
| Destination shape | Naive concatenation result | Query-aware result |
|---|---|---|
Plain path (/shoes) |
Works | Works |
Existing query (/shoes?color=red) |
Two ? marks. utm_source is lost, and color becomes red?utm_source=newsletter |
Works (& joins the tags) |
Fragment (/shoes#reviews) |
All tags land after #, which browsers never send to the server |
Works (tags go before #) |
| Query and fragment | Original query survives, all UTM tags land in the fragment | Works |
| Trailing space in the cell | Link contains a space, so most auto-linkers cut it off there | Works (space trimmed) |
Trailing ? |
?? creates a parameter named ?utm_source, so source is lost |
Works |
Five of the six shapes broke under naive concatenation. None broke under the query-aware builder. Product pages with filters and help pages with anchors are exactly the URLs a bulk sheet tends to contain.
Two other errors are common in bulk runs. Mixed case splits one value into two rows, since Google Analytics treats Facebook and facebook as different sources. Duplicate rows create two links for the same placement, which splits clicks between them. For the checks to run on a CSV before generation and what to do when a bad batch is already live, see the guide to generating UTM links in bulk.
Frequently Asked Questions
What does bulk link creation mean?
Bulk link creation means producing many links in a single run from structured input, rather than one at a time in a form. The links themselves are ordinary URLs, short links, or QR codes. “Bulk” describes how they were made and managed. The term covers UTM-tagged URLs, branded short links, and tracking links generated together.
Is bulk URL creation the same as bulk URL shortening?
No. Bulk URL creation builds the full destination links, usually by adding UTM parameters to each URL. Bulk shortening converts a list of existing long URLs into short links. Many campaign tools do both in one batch: tag first, then shorten each tagged URL, so the short link carries the tags to the destination.
Can you create links in bulk with Google Sheets or Excel?
Yes, with a formula that joins the destination URL and the parameter cells, for example =A2&"?utm_source="&B2&"&utm_medium="&C2. That formula is the naive concatenation from the test above, so it breaks on URLs with an existing query or a fragment. It also has no naming-rule validation and no record of who created which link. Spreadsheets work for small, clean lists. Larger or shared runs are safer in a dedicated tool.
How many links should one bulk batch contain?
Keep one batch to one campaign or launch, whatever the row count. A batch that mixes campaigns is hard to audit and hard to roll back if one value is wrong. Size matters less than scope: 300 rows for one product launch is easier to check than 40 rows spanning five campaigns.
