Online holiday shopping is off to a strong start, as new data released this morning from Adobe Systems Inc. suggests online sales increased 19.8% year over year so far in November.

Plus, on each day from Nov. 1-11 (Veteran’s Day), more than $1 billion was transacted on the web in the U.S., Adobe says. In 2016, only nine of those 11 days experienced more than $1 billion in sales.

Revenue from smartphones represented 24% of total purchases for the first 11 days of November and increased 40% year over year, while conversion rates across all devices grew by double-digit percentages:

• Desktop: Conversion rate was 4.6% (21.7% growth)
• Tablet: Conversion rate was 4.1%  (12.3% growth)
• Smartphone: Conversion rate was 1.8% (16.2% growth)

Separately, Internet Retailer analyzed website traffic patterns so far this November, and found similarly strong results.

Worldwide desktop and smartphone visits to a list of the largest 100 holiday-focused shopping sites selected by Internet Retailer from Nov. 1-11 reached 1.91 billion—a 7.3% increase compared with 1.78 billion visits during the same period last year.

Visits to Amazon.com grew even faster, as it experienced 970.8 million visits during the period—a 12.8% jump compared with the same period last year. That means Amazon’s share of total visits to the top 100 holiday-focused sites has increased so far this year to 50.8% of all visits, compared with 48.3% in 2016.

Here are the 10 most-visited shopping sites Internet Retailer tracked Nov. 1-11.
