What, if any, effects does changing the name of a product have on an item? I.e. does it lose search indexing value?



I want to rename one of my products which has been around for about a year now. The reason to rename is to compete with similar products who use specific keywords which I am trying to target.

But what I want to know is there any adverse effects of renaming a product? I know that it use to break the Twitter count of product mentions (not that I care too much about this) but does it do anything else? I.e. do older products with lots of sales have a better indexing in search results? What about potential backlinks to my product? Would renaming it be harmful?
