Walmart Inc tussle with Amazon has been ongoing. World's largest brick-and-mortar retailer recently made extensive changes to its website to win market share from Amazon.

The company lets its shoppers pick up and return online orders in stores. It plans to expand its grocery home delivery services to reach more than 40 percent of U.S. households.

The website will get a wider range of colors, fonts and more informal photographs. Walmart updated its website in 2014, but it was not as dramatic. As part of the recent changes, Walmart's new homepage will be personalized to customers' locations, and will showcase products that are trending in their regions. Different product categories will also have different layouts, allowing customers to shop for groceries differently from how they buy, say, home improvement products.

Walmart said in February that online sales increased 23 percent in the most recent quarter, less than half the rate of growth in each of the previous three quarters. The company posted about $11.5 billion in U.S. e-commerce revenue for the full year, which was a small percentage of the total U.S. sales of $318.5 billion.

Though the company might be finding it difficult to keep pace with Amazon, the company officials said that Walmart was still on track to increase its e-commerce sales by 40 percent this year.
