Hi, I set-up a UK Google Merchant feed about 8months ago now which is automated for around 25K products. I am trying to work out why some other sites still rank better than mine in the Shopping listing under the default 'Relevancy' filter. I have both a greater number and better reviews than the competitors and am showing a better price. I wonder whether anyone has any information on whether the following factors affect the listing position under the 'Relevance' filter: 1 - Age of the listing or domain 2 - Historic 'Click-Rate' for domain in Shopping listing 2 - Overall quality of the data feed i.e. do errors or warnings for other products in the feed affect the positions of all items in the feed? 3 - Bounce rate or on-page time of clicks to target site 4 - Diversity of review sources 5 - Google Checkout reviews 6 - Company location in Google Local For an ecommerce site this positioning can make a big-time difference to sales, so I'm hoping someone has run some tests on this they can share, and if not then why not? Hoping someone can throw some light on this, as I can't find a great deal out there on this fundamental revenue stream for me. Simon
