Does Channeladvisor really assist in SEO?

[ABCPS]

I'm getting emails from Channeladvisor recommending I join, thereby taking advantage of a change to Google Shopping.

It is starting in Australia from today (13Feb13).

Is it an upgraded version of Google  Adwords, or another form of a Commerce Merchant (obviously with multiple channels,e.g. Ebay, Amazon etc)?

With Adwords, I found it too expensive for the type of product we sell (printer cartridges).

But the real question is, DO MY RANKINGS DROP FROM NOT USING CHANNEL ADVISOR?

Does anyone have any clues as to Channel Advisor and if by not taking it up, it can hinder your SERP's

Hi Anthony

I just wondered if you had started to use Channel Advisor as we have recently been approached by them too.

In particular using their platform for feeding into shopping comparison sites.

Thanks
