When it comes to your product feed on Merchant Center, your product titles and descriptions are arguably the most important attributes for two reasons. Firstly, this is what shoppers will see when they’re served your ad. But it’s also key in telling Google what your product is so it can be crawled accurately.
Your titles and descriptions are where you get to display what you’re selling. You want to use concise, simple language that accurately describes your product. Keep it as relevant as possible while providing as much detail as you think necessary, especially in your descriptions.
Using relevant keywords in your titles and descriptions will help Google crawl your product feed, identify what you’re selling, and match your ad to the most appropriate search queries being used. Avoid keyword stuffing, however, as Google will penalise this. Avoid repetition, and don’t forget that you’re trying to show off your product(s) in a straightforward and clear manner.
