As we put out links that draw people back to our sites, it's important to do it properly so the traffic can be analyzed in Google Analytics.
There are 5 possible parameters that can be added to any link that can be helpful...
Required on all links with link tagging.
This is the most broad category. It's the general type of link. Common values used by google should be used whenever possible...
Required on all links with link tagging.
This is a narrowing of the medium - the name of the website on a referral, etc. Here are some good examples...
Required on all links with link tagging.
This further narrows the source, down to a particular marketing effort. Here are examples...
Notice the use of - and + in the links. + signs will come through as spaces. So Dan+Wong+Fan+Page will result in "Dan Wong Fan Page" coming through in the reports.
Also notice that you may need to be a little redundant. For example, saying "danjwong Twitter" after you just set the source to Twitter. This has to do with the reports. If there's another danjwong campaign for something else, they should be kept separate.
This parameter is completely optional. It lets you refine things even further. Here are some good examples...
If there are multiple levels of detail left to express you have to express them all in the content parameter. However, as yourself whether the levels are really necessary. For example on the first example you might have wanted to put "Twitterfeed+Dan+Wong+Videos", but you'll be capturing that on dan-wong.com - so if it came through Twitterfeed, you already know it was the dan-wong RSS feed that was used. If you do need to put more than one concept into content, put the most general first.
But generally this level is used as a refinement - exactly which banner ad, exactly which link in an email, etc.
This is pretty much never used in our situations. It is used when the click is the result of a search - the search term would go in as 'keyword'. But I can't imagine a situation where that would apply for us.
