...WSofi Google Analytics Tagger is the way businesses track sales from their origination point (like a tweet, email or a brochure) down the funnel to their conversion page. Every audience development campaign is packed with UTM codes to see which campaigns perform best. In Google Analytics, these codes can be tracked under the general “Traffic Sources” area just like any other source
You can use it to tag your advertising efforts, run link building competitions (by getting staff to enter their name in the source field and creating 8 league table of conversions) or just save you when tagging your links.
