[2026 Latest] What is the EC Advertising Type List? Basic Knowledge of Ad Operations to Maximize Sales
In the EC business, "ad operations" are an unavoidable part of achieving stable sales growth. However, as of 2026, with the increasing diversification of platforms, many owners are unsure which ads to invest in. Correctly understanding the list of EC advertising types and selecting media that match your company's phase is the key to maximizing return on ad spend (ROAS). In this article, we will classify major EC advertisements using the MECE (Mutually Exclusive, Collectively Exhaustive) principle and provide a thorough explanation of their characteristics and applications.

1. Basic Classification of EC Advertising: In-Mall vs. Out-of-Mall Ads
EC advertising is broadly classified into two types: "In-Mall Ads" and "Out-of-Mall Ads." In-Mall Ads are delivered within giant platforms such as Rakuten Ichiba, Amazon, and Yahoo! Shopping, while Out-of-Mall Ads drive traffic to your own site or the mall through Google, Meta (Instagram/Facebook), etc.
In-Mall Ads, in particular, allow for a direct approach to users with extremely high purchase intent, so it is a fundamental rule to start by optimizing In-Mall Ads in the early stages of an EC business. The following chart shows the budget allocation trends by advertising medium for a typical EC site.
2. Importance of Search-Linked Advertising (Listing Ads)
Search-linked advertising refers to ads displayed when a user searches for specific keywords. In EC, it is an essential means to reliably capture "active prospects" searching by product or category names. Amazon Sponsored Products and Rakuten RPP ads fall into this category.
The biggest advantage of this type of advertising is the ease of controlling CPA (Cost Per Acquisition). On the other hand, since the CPC (Cost Per Click) tends to skyrocket for keywords with high competition, advanced operational skills are required to select long-tail keywords and reduce wasted spend through negative keyword settings.
3. Awareness Expansion Strategy via SNS and Video Advertising
To increase brand fans and enhance LTV (Lifetime Value), utilizing SNS advertising such as Instagram and TikTok is indispensable. In categories like apparel, cosmetics, and food where visual appeal is possible, video ads tend to have a higher CVR (Conversion Rate) than static images.
As for 2026 strategies, the mainstream is moving away from simple product introductions toward "how-to videos" that solve user problems and highly reliable creatives utilizing UGC (User Generated Content). The shift from "ads for selling" to "ads for conveying experiences" is the turning point for success in SNS operations.
4. 2026 Trends: Utilizing P-MAX and AI Auto-Optimization
In the latest EC ad operations, AI-driven advertising, represented by Google's P-MAX (Performance Max), cannot be ignored. This is a system where ads are automatically delivered across all placements—Search, Display, YouTube, Gmail, etc.—within a single campaign.
Since AI learns which users are most likely to convert and adjusts bids in real-time, it has become possible to maintain a high ROAS while significantly reducing the workload for operators. However, because the quality of "assets" (images and text) provided to the AI determines the results, creative production capabilities are being emphasized more than ever.
FAQ
- Q. What is the minimum budget required to start EC advertising?
- A. It depends on the medium, but for mall search ads, effectiveness can be tested starting from about 50,000 to 100,000 yen per month. Since a certain amount of data is required to optimize AI learning, we recommend an initial budget of approximately 100,000 to 300,000 yen.
- Q. Which should I prioritize: ads for my own site or for the mall?
- A. If you already have a store in a mall, please prioritize In-Mall Ads. Because traffic-driving power and reliability are guaranteed, it tends to be easier to achieve sales targets in a shorter period compared to your own site.
- Q. How long does it take to see results from ad operations?
- A. Initial data is typically accumulated within about 2 weeks to 1 month. We run PDCA cycles based on that data, and ROAS generally begins to stabilize from the 3rd month onwards.
