Only 45% of the Top 100 Internet Retailers Employ a TMS

60% of the top 100 internet retailers (the IR100) have 10 or more tags deployed on their sites (including web analytics tracking tags), yet only 45% of them employ a tag management system (TMS).  Each of these retailers preaches the importance of accurate web analytics to measure conversion rates, but the majority suffered 4 points of pain:

1. Completed Tag Presence
   93% of IR100 had an incomplete implementation of all of their tags.
   (Solve this problem by conducting regular tag audits.)
2. Site Load Time
   Companies with a TMS had a 4.54% faster load time.
3. Rate of Duplication
   47.6% higher rate of duplication for companies without a TMS.
   (Duplication is having more than 1 tag with the same account variable.)
4. JavaScript Errors
   9% more javascript errors for companies without a TMS.
