Amazon Sales Trends: Day of the Week Performance Analysis

Identifying and capitalizing on sales trends to help sellers stand out from the competition

Which day of the week do we tend to see the highest sales on Amazon?


Selling on Amazon continues to get more competitive, so identifying and capitalizing on sales trends can help you as a seller stand out from the competition, maximizing sales without giving up on profitability.

One of the trends that we track is shopping habits and how the day of the week performance impacts key metrics like sales and conversion rates. Understanding the shopping trends of your customers and optimizing your campaigns to match with how your sales fluctuate throughout the week can help make a huge difference. 

Since we aggregate data throughout multiple markets and products, we’re able to see wide-ranging trends that we can apply down to the account level. This allows us to adjust bids and/or budgets to be more aggressive on the days where conversion rate is most likely higher. As a seller, if you spend more when shoppers are more likely to convert, you’ll likely net higher sales and lower ACoS.

What is the busiest day of the week for sales on Amazon?

While each customer is unique on the Amazon platform, we definitely see trends in our client’s accounts in overall sales and conversion rates. Previous studies of online shopping like that found on indicated that Sunday and Monday were the busiest days for online sales.

Intuitively, this makes sense right? People enjoy their weekend and then as they prepare for the workweek, complete a lot of their online shopping on Sundays. Except for one thing – we weren’t exactly seeing the same impact after assessing our clients’ accounts.

As of May 2021, Mondays have the highest traffic and sales.

Shoppers follow patterns over the week and after pulling data from 100M clicks, we find that Mondays are the best days.  Both traffic and purchase intent are at their peaks on Mondays, which means high search impressions and ad efficiency.  Tuesdays follow up to be the second-best day with above average traffic and conversion rates coming in slightly less than Mondays at 14.1%.


While the graph above lays it out best, here’s a quick breakdown by each day:

Sunday This is a high traffic day. However, we’re seeing the lowest average conversion rates which means shoppers are doing a lot of browsing but their purchase intent is low. 

Monday This is the best day overall. Mondays have proven to have the highest traffic and the highest conversion rates throughout the week. When optimizing campaigns from both a growth and efficiency standpoint, this would be the day to ramp up bids and budgets. 

Tuesday Tuesdays come in as the second-best day for conversion rates. After assessing our data, we’re seeing above average traffic which shows that shoppers are still looking around while also completing some of the purchases. From an optimization standpoint, Tuesdays can also be a great day to increase bids to help capture sales. 

Wednesday Wednesdays also perform well with an above average traffic and above average conversion rate.

Thursday Traffic declines on Thursday.  However, conversion rates remain slightly above average. This shows that shoppers on Thursdays are usually more intentional with their purchases and likely know exactly what they’re looking for.

Friday Fridays show the lowest traffic but with a slightly above-average conversion rate.

Saturday We’re seeing low traffic on Saturdays with low conversion rates. From an optimization standpoint, this would be a great day to cut back bids and budgets due to the lower buyer intent and sales volume.

Optimizing Bids for Buying Trends and Patterns

We can fully optimize our bids by using these repeatable sales trends to take advantage of the best sales days on Amazon. When predicting high conversion days, we can get more aggressive with bids to help maximize sales. On lower converting days, we can decrease bids to reduce wasted spend and lower ACoS.

By increasing the bids when our customers are most likely to buy, we can increase the frequency our ads are shown leading to more clicks and sales. Since our customers will convert at a higher rate during these times, we can afford to pay more since we’ll be getting a better return per click. Taking the same approach, we can reduce bids on days when customers have a lower purchase intent.

We use a trained machine learning model to find repeatable patterns like these to take these bid updates to the next level. However, if you know the trends for your account, you can even make these moves manually or through bulk files.
