Relevancy and You
Relevancy is applied similarly to keyword searches when submitting to Google Base and Merchant Center.
The idea is to increase relevancy you must find out a couple things about the market you are in.
Are you competitive on pricing? Base and Merchant Center are also tactical tools, you can find the best price by searching for stuff as well and then match or beat this price if it is fiscally possible. The most common method of purchasing for the consumer is by the lowest price. So, you need to be in the ball park on pricing. One thing to note here, some sites use the lowest price as a way to drive traffic. I call these "PPT's" or Predatory Price Traffickers. They have no intention of selling product or services, they just want to increase traffic to their site. In the end it hurts the customer because they waste time dealing with the "PPT" and don't get what they are looking for.
What type of search trends are being used by consumers. Are they using very specific key terms to find products that you offer? Or, is it a broad generalized key term that is the most often used? You need to know what the customer is searching for to apply that to you data feed thus increasing the relevancy to that particular search.
Do you have a detailed description of the product? Submitting very detailed and exact information influences relevance based on the search term as well.
There are a plethora of different attributes available that will increase the visibility of products on Base and Merchant Center.
