Agree with CM entirely.
In fact price should be nowhere near the top of that list:
You can increase far more by using upsells - or combining your (commoditiy) product with other things to make the offer distinct.
Copy and ( credibility as part of copy) are critical.
Hi
I pointed out (just before you posted) that Price is simply one factor I have chosen to show as I thought people would be able to instantly recognise it as an affecting factor.
Price is not the no. 1 factor.
Your post is interesting, thanks for sharing.
I would say that for ecommerce retailers selling branded products, then in my opinion price is quite important, not the no.1 factor no, but definitely important.
If you had 2 identical websites selling the same product, but one was cheaper I would expect that the cheaper site would attract more sales.
I realise 2 websites with exactly the same level of factors to influence a sale is highly improbable, but even 2 different sites with similar traits, both instilling a similar level of trust in a consumer, the site with a more competitive price would surely attract the most business.
Many times I see people asking why their site isn't selling enough products and I can see that as a potential customer it takes just a minute or so to find a site with a better price.
More often than not their sites could be vastly improved upon in terms of usability and trust building, but if they can't compete with a larger, more popular, and 'seemingly' more trustworthy competitor on price then maybe their full business model needs some more work.
However, if they could offer a similar, or in some cases, better price, then their potential for both their site and business is far greater.
I'm probably leaving the realms of conversion rates now and venturing into business models as a whole, so I'll end it there.
Thanks for the comments anyway,
Darren
