A UTM link is a normal web address with a few tags added to the end, such as utm_source and utm_campaign. When someone clicks it, your analytics tool reads the tags and records where the visit came from. That is how you tell a click from a creator’s TikTok apart from a click from an ad or an email. Octoclip is A marketplace where brands hire creators directly, at a fixed price per video. Octoclip is not An analytics tool. The builder makes the link; your own analytics reads it.

A naming scheme you can keep for every campaign. 1. **Source is the platform** tiktok, instagram, youtube, newsletter. Where the click happens. 2. **Medium is the kind of traffic** creator for a creator’s own post, paid-social for an ad, email for a newsletter. 3. **Campaign is one name per push** spring-launch, not Spring Launch in one link and spring_launch in the next. 4. **Content tells posts apart** Use the creator’s name or the video, such as ava-video-1, so you can compare them. 5. **One link per creator** Give each creator their own tagged link for their bio or story, and you can see whose post sent the visits.

There are five: utm_source, utm_medium and utm_campaign, which most people always fill in, and utm_term and utm_content, which are optional. ### Are UTM parameters case sensitive? In most analytics tools, yes: TikTok and tiktok are counted as two sources. This builder puts everything in lower case for that reason. ### Do UTM links work on TikTok and Instagram? They work anywhere a link can be clicked: a bio link, a story link, an ad. A web address typed into a caption is not clickable, so use the bio or the ad. ### Where do I see the results? In the acquisition or traffic-source reports of your analytics tool, grouped by source, medium and campaign. ### How do I track which creator sent a sale? Give each creator their own link with their name in utm_content. Your analytics then shows visits and sales per creator, and the [CPA calculator](https://octoclip.io/cpa-calculator) turns that into a cost per sale. ### Can a tagged link tell me how many sales a creator will bring? It shows what happened after a post went live, not what will happen. Octoclip does not sell or guarantee downloads, installs or views. You pay a fixed price for each approved video. ### How much does it cost to hire a creator? Posting a job, reviewing applicants and sending offers are free. You set a fixed price per video and pay only when a creator accepts your offer. The full amount is shown before you send the offer. **A person answers.** Can’t find your question?
