What Is Web Advertising? Types, Costs, and How to Start for Beginners
Now that smartphones and PCs are indispensable to daily life, the importance of web advertising as a customer-acquisition channel for businesses keeps growing. At the same time, you often hear voices saying “there are so many types that it’s confusing” or “I’m anxious about how much it will cost.”
This article clearly explains, for beginners, what web advertising is—from the basics to the representative types, costs and billing methods, and how to get started.
Web advertising is a general term for ads placed on media on the internet, such as search engines, websites, social media, and video services. It is also called “internet advertising,” “online advertising,” and similar terms, all of which are used with roughly the same meaning.
Compared with “mass advertising” such as TV commercials, newspapers, and magazines, the main features of web advertising are as follows.
The greatest appeal of web advertising is that “you can try it from a small amount and improve while watching the numbers.”
There are many types of web advertising. Here we introduce the representative ones that beginners should first keep in mind.
These are ads displayed in the search results of Google, Yahoo!, and others. Because they are shown in line with the keywords a user searches for, their strength is the ability to approach “people who are searching right now.” They make it easy to target high-purchase-intent segments, and are widely used for customer acquisition.
These are image or text ads displayed in the ad spaces of websites and apps. Because they can approach even people who do not yet know the product, in a visual way, they are suited to awareness-building and branding.
These are ads placed on Instagram, X (formerly Twitter), Facebook, LINE, TikTok, and the like. They allow highly precise targeting based on detailed user information, and are also characterized by being easy to spread.
These are ads that play before or during videos on video services such as YouTube. They can convey a lot of information through visuals and audio, and are suited to communicating the worldview and usage of a product or service.
In addition to the above, “affiliate advertising,” where a reward is incurred only when a result is produced, and “retargeting (remarketing) advertising,” which displays again to people who have once visited the site, are also commonly used.
The cost of web advertising becomes easier to understand if you think about it from two perspectives: the “billing method” and the “budget.”
Many web ads are “managed” ads, where you can set an upper-limit budget yourself. For example, you can use them in ways such as “setting a daily upper limit so that you are not charged beyond it.” For that reason, there is no single correct answer of “from how much,” and while some companies start with a small budget of around tens of thousands of yen a month, others invest millions of yen. The basic approach is to start with a budget you can manage and adjust while watching the results.
If you are taking on web advertising for the first time, you can start without omissions by proceeding through the following steps.
Web advertising is not “run it and you’re done”; results grow by repeatedly watching the numbers and improving after the ad goes live.
Web advertising can be managed in-house or outsourced to an ad agency. It is good to choose according to your resources and purpose: in-house management if you want to start small and accumulate know-how, or outsourcing if you want to seriously grow results without spending the man-hours.
Web advertising (internet advertising / online advertising) is a general term for ads placed on media on the internet. The major differences from mass advertising are that detailed targeting is possible, you can start with a small amount, and effectiveness can be measured numerically.
The types include search, display, social media, video, and more, and billing methods range widely, from cost-per-click to cost-per-impression. First, with the flow of “decide your purpose → choose your target and media → try it from a small amount → watch the numbers and improve,” try making a small start with the ad that suits your business.
