WoomyCasting Adds "Scheduled Posting Function" to Ensure Influencer PR Posts for Rakuten Super Sale and Other Events are Posted During Golden Time

■ Background of this Release: Determining the Priority of Posting Timings for Sale PR

During large-scale sales on mall-type e-commerce platforms such as Rakuten Super SALE and Amazon Prime Day, requests for influencer collaborations often overlap, leading to problems where requested PR posts are not made during optimal time slots.
To address this, WoomyCasting has added a "Scheduled Posting Function" to ensure that Woomy's campaigns are posted at the most optimal times, thereby securing PR posts at the highest priority and most effective timing.

■Optimal PR Posting Times for Rakuten Sales PR

The following are the results of a mathematical analysis by AI (Gemini 3.1 Pro) of millions of SNS posting data obtained by Woomy from Meta's official Graph API, specifically focusing on related posts during Rakuten sale periods (Super Sale and Rakuten Marathon from April 2024 to March 2026).
The median and average data are calculated with the first hour of the sale set as 100.

*Analysis is based on insight posting data obtained from Meta's official Graph API.
*Mathematical normalization processing has been applied to ensure that the data is not affected even if influential influencers post at the same time.
*Posts related to "summary posts (recipes, how-tos, etc.)" that significantly impact the number of saves have been excluded from the analysis by AI (Gemini).
*Posts related to purchase reports tend to increase in reach and saves even after the sale, but all figures after the end of the sale period have been excluded from the analysis.
*Since the duration of each sale differs, if it overlaps with the day before the final day or the final day, it is analyzed as the day before the final day or the final day.
*Posts related to purchase reports towards the end of the sale tend to have increased reach.
*Please note that this data does not indicate posts that led to purchases.
*Similarly, for Amazon Prime Day and Qoo10 Mega Discount, posts made on the evening of the day before also showed a tendency for increased reach and saves.

Golden Time for Rakuten Sales

These are the optimal time slots analyzed by AI (Gemini 3.1 Pro) from the posting data (provided by Meta's official Graph API) obtained above.

1st Place: "Day Before" the Sale, 6 PM to 11 PM

Index: Reach (113.2) / Saves (123.7)

Reason: This is the golden time where **"saves" are maximized (more than 1.2 times the baseline value)** across all periods and time slots.

Strategy: This is when users are most seriously considering "what to buy in tomorrow's sale" while in bed or on the sofa, and creating lists (saving items). By accumulating saves at this time, Instagram's algorithm recognizes these as "high-interest posts," which acts as a "pre-investment" to make them more likely to appear in recommendations (Explore tab) when the sale starts the next day.
Since figures tend to decrease after 11 PM, it is recommended to post by 11 PM.

[2nd Place] Day of Sale (Today), 9:00 PM to 11:00 PM

Index: Reach (105.3) / Saves (120.1)

Reason: Golden time after the "fierce competition" noise of the 8 PM hour subsides.

Strategy: Users who have finished the coupon scramble around 8 PM start to relax and browse for "anything else they forgot to buy." During this time, post density decreases, so the timeline occupancy time per post mathematically increases, making it easier to extend reach. Instead of "breaking news," **"still time!" or "this is actually a hidden gem"** type of in-depth suggestions attract both saves and purchases simultaneously.
Since figures tend to decrease after 11 PM, it is recommended to post by 11 PM.

[3rd Place] 5th Day

Index: Reach (112.2) Saves (104.9)

Reason: If it's a point-up day (a day ending in 5 or 0), the numbers dramatically increase.

Strategy: By announcing at the beginning of the caption, "Don't buy today (the 8th), save it and prepare for tomorrow night at 12 AM (the moment it becomes the 10th)!", you can reliably catch the wave of reach and create a "reservation" state that directly leads to sales on the 10th. However, it is thought that the number of saves leading to purchases tends to decrease towards the end of the sale.

*About AI Optimization and Unique Calculation Logic

Each "index" listed in this ranking is a practical comprehensive score calculated by AI, integrating the two time slot data points of "6 PM to 9 PM" and "9 PM to 12 AM" from the table above with a 50% weighting each. Furthermore, the reason for specifically recommending "until 11 PM" instead of "until 12 AM" is that real data clearly shows a tendency for user activity and insight values to decrease from 11 PM onwards into the late night. By deliberately cutting out the late-night noise (the last hour) that lowers performance, only the pure golden times with the highest return on investment (ROI) are carefully selected and extracted.

■ Unique Feature: Introduction of "Advance Posting Reservation" Not Found in Other Companies

WoomyCasting has implemented a function within Woomy Casting that requires influencers working on WoomyCasting campaigns to "set up a scheduled post on SNS by the day before posting and report its completion."

For sale PR, requests for PR tend to flood in at specific times, including campaigns from companies other than Woomy. Influencers often have difficulty making consecutive posts and therefore prioritize and post campaigns based on their own judgment.
With this new function, by having influencers make advance posting reservations using the "Scheduled Posting Function," WoomyCasting PR posts can be prioritized and posted during the time slots that maximize their effectiveness, preventing WoomyCasting PR campaigns from being deprioritized. At the same time, it also prevents forgotten posts and delayed posts.

WoomyCasting for Sale-Related PR in Malls!

Woomy has previously achieved results as a "platform aimed at maximizing profits in proprietary e-commerce (own domain sites) where external tags can be freely installed," using its unique CV measurement tool (Zero Affiliate) and UGC (WOOMY UGC) tool.
Now, by systemically guaranteeing the "certainty of posting at specified times during sales," which is a unique challenge for mall-type e-commerce, Woomy believes it has established a clear advantage over other influencer platforms in both proprietary e-commerce and mall-type e-commerce battlefields.
