UTM Naming Conventions That Remain Useful at Scale

A UTM convention usually breaks down because the rules were never documented. Once several people create links, small differences such as "facebook" and "Facebook" begin splitting the same traffic into separate rows in analytics. As Improvado's naming-convention guide recommends, start with one written reference that defines how every parameter should be formatted. Everyone who creates a tracked link should use that document. At minimum, it should list approved values for utm_source, categories for utm_medium, and a consistent order for the information included in utm_campaign. A campaign value might include the product, audience, and quarter in that order. Formatting needs to be consistent as well. Use lowercase values throughout, and choose either hyphens or underscores for terms containing several words. Do not use spaces. This is more than a visual preference. Analytics platforms treat differently capitalized values as separate sources, as described in Cometly's tracking best practices. Teams managing several clients should also standardize account and client labels. A predictable label makes cross account reports easier to filter and reduces the need for manual cleanup. Review the data once a month to make sure the convention is still being followed. Export the source, medium, and campaign values, sort them alphabetically, and look for spelling differences or duplicate names. Correcting a few links each month is much easier than repairing a year of fragmented reporting. bm2500 offers a UTM template that can be adapted for this purpose.
