January 2016 y/y SSS Results 

As a reminder, December 2015 was unusually slow y/y  because Cyber Monday was in November.  In 2014, Cyber Monday was in December.

Here are the ChannelAdvisor SSS results for January 2015:

  • Amazon – Amazon’s January SSS came in at 17.8%,  an increase compared to December’s 15.5% and essentially ‘in-line’ with the 15% e-commerce growth rate.
  • eBay –  eBay’s January SSS came in at 4.0%,  an increase from December’s 0.8% and well below the e-commerce growth rate of 15.0% as predicted by comScore.  Further in the report, we have details of the eBay internals.
  • Other 3PM -Non eBay and Amazon marketplaces for January came in at 24.1%, a decrease from December’s 26.4%. 
  • Google Shopping/PLA – GS came in at 32.9% y/y growth for January, an increase from December’s 26.3%.  Google Shopping details are provided later in the report.
  • CSE – Comparison Shopping Engines came in at 6.3% for January, an increase from December’s negative 8.0%. CSEs increased due to the strong showing in Google Shopping for January.  Details on PLA/Google Shopping later in the report.

Amazon details

We watch two Amazon internal data points around FBA adoption and FBA/off-Amazon trends:


  • Percent FBA – This measures the % of Amazon GMV through the ChannelAdvisor system that was fulfilled through FBA and tracks it on a y/y basis.  For January 2016, 37.8% of Amazon GMV was FBA.  That was up 20.9% from a year ago, January 2015, where 32.9% of the SSS GMV was FBA.
  • % FBA non Amazon – Here we look at the total bucket of FBA-driven GMV and look at the % that was not fulfilled for Amazon sales (website, other 3PMs, Search, CSE, etc.).  A year ago in January 2015, 1.8% was non-Amazon fulfilled.  Then in January 2016, we saw this grow 39y/y to 2.5%.

Note: These are all y/y SSS comparisons (January 2015 vs. January 2016).

Clicks (a measure of volume) were up 7.0% and cost was up 15.0% due to the increase in clicks and an increase in CPCs of 7.4%.  Orders were negative 4.6% due to a decrease of 10.9% in Conversion Rate (CR) to 3.12%.  AOV saw a nice increase of 3.1% y/y to $147.40.

Supplemental data for Google Shopping

Here is the January 2016 Google Shopping/Product Listing Ad supplemental data:


Overall, Google Shopping/PLA for January came in up 32.9% y/y.   The conversion rate was down this month y/y declining 12.1% from 1.32% (Jan 15) to 2.04% (Jan x). AOV increased 2.9% from $107.00 a year ago to $110.06 in 2016.


January kicked off 2016 and e-commerce channels performed similar to Q4 2015.   We saw Google Shopping/PLA, Other 3PM, Amazon and eBay P+A meeting or exceeding the ~15% comScore e-commerce growth rate baseline, while eBay, Search and CSE grew slower than the baseline.
