Amazon.com Inc., No. 1 Internet Retailer 2017 Top 500, accounts for more than half (55.8%) of all traffic to the 10 most-visited general merchandise sites, according to SimilarWeb.

The digital analytics firm recently released a report that detailed which retailers received the most traffic in the U.S. by category between January and April of this year.

Here are the leaders in each category:

• Home Depot Inc. (No. 8), Home and Garden
• Best Buy Co. Inc. (No. 10), Consumer Electronics
• Macy’s Inc. (No. 6), Apparel
• Sephora USA Inc. (No. 136), Beauty
• Nike Inc. (No. 37), Sporting Goods

The 10 most-visited general merchandise sites with their share of traffic are:

Within the General Merchandise category SimilarWeb also found:

• “Fidget spinner” (a popular children’s trinket) is the most-searched nonbranded keyword on Amazon.com, eBay.com and Walmart.com in 2017.
• Among Wal-Mart Stores Inc. (No. 3 in the Top 500), eBay Inc. and Amazon, consumers spend the most time in the Walmart app: On average consumers spend 36 minutes 44 seconds per day in Walmart’s app; 20 minutes 36 seconds in eBay’s app; and 8 minutes 25 seconds in Amazon’s app.

In the Home and Garden category, Home Depot captured the most traffic among the top 10 sites from January-April.

The bottom seven retailers received the remaining 23.1% of traffic.

Among the top three retailers, Wayfair Inc. (No. 16) has the lowest portion of its traffic coming directly to its site, which means the retailer has less brand recognition than Home Depot and Lowe’s, SimilarWeb says.

Like Amazon in general merchandise, Best Buy dominates the Consumer Electronics category with 48.5% of the traffic in the January-April period.

SimilarWeb also found:

• Four of the top five site searches on Bestbuy.com were for Nintendo products.
• Best Buy’s web traffic is two times higher in November than the rest of the year.
