Note: This is a monthly feature published by ChannelAdvisor highlighting the Same Store Sales (SSS) across our wide range of thousands of retailers and billions in GMV.  Details on the SSS including background, methodology, disclaimers and the 2016 schedule can be found in this post.

Here are the ChannelAdvisor SSS results for June 2016:

  • Amazon – Amazon’s June SSS came in at 11.6%,  a slight decrease compared to May’s 12.3% and essentially ‘in-line’ with the 15% e-commerce growth rate as predicted by comScore. Further in the report, we look at Amazon details and FBA adoption rates.
  • eBay –  eBay’s June SSS came in at 3.8%,  an increase from May’s 2.8%  and about 1/3 the e-commerce growth rate of 15.0%.  Further in the report, we have details of the eBay internals.

eBay’s SSS for June were up 3.8%.  To get a feel for what drove the marketplace’s performance, here are the interior data points for the month:

Amazon Details

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


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

  • 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 June 2016, 41.6% of Amazon GMV was FBA.  That was up 35.7% from a year ago, June 2015, where 33.5% 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.).  In June 2015, 3.2% was non-Amazon fulfilled.  Then in June 2016, we saw this decrease 24.3% to 2.5%.  More and more Amazon deliveries are being made directly by Amazon and thus don’t have tracking numbers that are needed by the non Amazon marketplaces (eBay, Walmart) and Amazon sellers’ websites.

Supplemental data for Google Shopping

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


Overall, Google Shopping/PLA for June came in up 26.2% y/y.   The conversion rate was down this month y/y declining 13.8% from 2.48% (June 15) to 2.14% (June 16). AOV increased 13.4% from $104.56 a year ago to$118.61 in 2016.

As mentioned previously, Google continues to turn all of the ‘dials’ on Google Shopping:

  • The Google Shopping ‘widget’ showed for more searches
  • The widget had higher placement
  • The widget increasingly had more products

Supplemental data for Search

Here are the June Search internals: (click to enlarge)


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

Clicks (a measure of volume) were up 8.2% and cost was up 1.7% due to the increase in clicks and a decrease in CPCs of 3.2%.  Orders were down 1.4% due to a decrease of 8.8% in Conversion Rate (CR) to 3.63%.  AOV decreased 2.1% y/y to $159.43.


June continued the trends we saw in May with a mix of channels growing faster or in-line with the e-commerce growth rate of 15%, including Other 3PM, Google Shopping, CSEs, eBay P+A and Amazon.  eBay FP/Auction and Search were flat to down y/y.  We’ll be watching how things trend through Q3 as we get ready for the 2016 holiday season.
