Every retailer is looking for a way to get their Google Shopping results to stand out. If you’re using other Google products such as Google AdWords or Google Checkout, then you’re familiar with the special Google Checkout badge that you can get to show up on your AdWords ads by linking your accounts. The same thing can be done with your Google Merchant Center account and your Google Checkout account. By linking your two accounts you can get your shopping results to display a Google Checkout badge, the blue shopping cart, and be included in the Google Checkout filter.

For some retailers, they only sell one type of product and it’s easy to categorize all their products for the shopping engines. For others however this can be an overwhelming task, especially if you have many products in a multitude of categories.
Proper product categorization is a critical foundation to a feed’s success on the shopping engines. Check out this earlier post on data feed categorization for details.
Many CSEs have promo messaging fields to use things like FREE SHIPPING or GIFT WITH PURCHASE. Be sure you are using a compatible promo message for each engine, as not all the messages can be used to every shopping engine. Be careful when including promotional text in your product titles and descriptions themselves, as this violates the policies of engines like Google and your listings can be flagged for removal.
Many of the shopping engines have rather minimal requirements for images in your data feed. Use images of at least 300×300 pixels and dont use generic images or image place holders. Also be aware that a few of the CSE’s don’t allow watermarks on images either. If you don’t have an image don’t make something up, or use a “no image available” image.
Here’s a link to an older post which has more details and suggestions.
Similar to your links breaking or listings coming down, verify that all your product bids are set. Any bids at the category or product level that are at a) zero, or b) below the min CPC will prevent your products from showing up. Many shopping engines also won’t list your new products unless a bid has been set on the category.
Do yourself a favor and login at least once this holiday season to verify. Also note that many of the CSE’s raise the category bid for the holidays. You can check out a post over at SingleFeed about 2010 rate increases.
We recommend that you install the ROI conversion trackers for as many of the CSE’s you can. These benefit your relevancy for CSEs that use conversion information in their ranking algorithms. Don’t be concerned about them slowing your site down, just place them at the bottom of the conversion page in the code. That way if one ever hangs up, at least the whole page has loaded and the shopper won’t likely notice a single tracking pixel not loading.
We’ve posted on this in the past- Nextag, Shopping.com, Become.com and Shopzilla are a few engines that have these ROI trackers available.
There is hardly anything worse than your website being down during the holidays. Something that I’ve seen and experienced personally when it comes to using the CSE’s is when the urls are broken and the shopper clicks never make it to your website. Maybe it was a url tracking tag that broke, or your feed file somehow had improper urls, whatever the case you don’t want to have this happen to you especially during the holidays. You lose the clicks/visits and you spend click fees.
