If organic search can account for fully a third of your revenue, if not more, what can you do to grow that?

Search optimization is a deep ocean, but here are some core areas where you can take action right now to improve your organic search visibility and win over a greater share of those 100 billion-plus monthly searches.

1. Craft unique, optimized descriptions.

Increase your odds for better visibility by crafting unique product descriptionsoptimized for keywordsrelated to the product and how customers will use it. Make sure you include the value proposition and impactful benefit statements, which can help increase visitor-to-customer conversions.

"Value proposition is the number one thing that determines whether people will bother reading more about your product or hit the back button,"wrotePeep Laja, founder of ConversionXL, for his book,How to Build Websites That Sell.

2. Don't forget about image optimization.

Images and photos should be optimized with targeted keywords. For products, keywords should be specific to the product name, make or model and manufacturer.

Image optimization includes the image name or file name as well as the alt tag associated with the image. Depending on the design and layout of your store, you might also consider optimizing brief image descriptions for each product photo.

Ina post forSearch Engine Journal,Jean Dionwrote, "That file name is part of the data Google examines and, in the absence of other valuable data, that file name might be used as the image's snippet in search results."

These actions can help your images appear in relevant image searches, which can drive additional organic traffic back to your product pages.
