Mediums

For a basic introduction to campaign tracking, read our campaign tracking introduction.

A medium is a method on how to get a user to your website. A medium is part of a channel. Just as you can travel with a bus (medium) or car (medium) on a road (channel) compared to riding a train (medium) on a railroad (channel).

It is often valuable to understand which mediums are bringing you (valuable) visitors and what the best mediums are to spend your money on.

When using the mediums functionality, you will have an overview of all used mediums, but Harvest will also be able to check whether your campaign tagging is done correctly.

Make sure you track your marketing campaigns properly. For more information about tagging your marketing campaigns, read our campaign tagging documentation.

Whitelisted sources

Source are the websites the user originated from. As an example we can use the medium organic_search. Known sources for the organic_search medium (search engines) are Google, Bing and Yahoo.

When filling in sources, you are going to make use of source whitelisting. This means that only sources you have linked are markes as valid sources. If someone use a source that is not in the whitelist, the tagging will be marked as invalid.

Note that if you leave this field empty, all sources tagged with this medium are marked as valid.

Linked channels

A medium is part of one or multiple channels. A channel is a way to group different channels in a related group. For example the mediums organic_search (non paid results in a search engine) and paid_search (search engine advertising) both are part of the channel Search.

It is important to think about how you group your mediums, because reports on channel level can valuable if you use them properly.
