We have launched the new new campaigns and want to measure the effectiveness by using results. When I tried to do that we observed following metrics (Key Performance Indicators) very useful. I hope those will help you too.
2. % of goal conversion rate by medium: Which medium is contributing more for getting goal conversions?
3. % of visits by source type: To know any online channel from which visitors arrive at your website.
4. Campaign Quality Index (CQI) : How well targeted your campaigns are at driving qualified leads.
CQI = (% goal conversions from campaign) / (% visits from the same campaign)
Interpretation of the CQI:
a. CQI=1 tells – a visitor from said campaign is likely to convert as a visitor from from any other campaign.
b. CQI= less than 1 (<1) tells – less likely to convert than a visitor from any other campaigns.
c. CQI= greater than 1 (>1) tells – visitor is more likely to convert than a visitor from any other campaigns.
