■What Is Search Keyword Targeting
Search Keyword targeting is a targeting function that uses the keywords searched for by a user of the various different types of Yahoo! JAPAN search functions. When a user who had searched for certain keywords in the past visits a Web page displaying the Yahoo! JAPAN Ads Display Ads another occasion, ads are displayed based on the search history of those keywords. This function allows for more refined targeting by each of the keywords. Also, since keywords employed in Search Adses are also used, this makes it possible to focus on the same target demographic.
Tips
	
Selectable options for the duration (effective period) of user’s search history for ad delivery are ‘within 1 day’, ‘within 3 days’, ‘within 7 days’, ‘within 14 days’ or ’30 days’. You can set the duration for each search keyword list.
	
Selectable options for the number of searches by user who can see your ads during the effective period are ‘once or more’, ‘twice or more’ or ‘3 times or more’. You can set the number of searches for each search keyword list.
	
When the system considered the searches by an unique user even on various devices (PC, smartphone, tablet or so), your ads will be delivered to the user with his/her search history basis.
Example:
In the case when an user searched in the past with Yahoo! JAPAN ID login, your ads will be delivered to the user even on the tablet which with same Yahoo! JAPAN ID login.
■Benefits of Using Search Keyword Targeting
	
More refined targeting by each of the keywords
Ads can be delivered to the desired users based on each of the keywords, which offer a more refined level of granularity when compared to typical targeting functions.
	
Complimentary role of Search Ads
Since keywords employed in Search Ads are also utilized in Search keyword targeting, this makes it possible to appeal to the same target demographic in Display Ads (Auction) as well. When combined with Search Ads, this allows for more focused promotions.
■Ad Delivery with Search Keyword Targeting
The user’s search term will be divided into single terms. Ads will be delivered when the advertiser’s registered search keyword matches the divided search term of the user.
Sample cases of keyword matching as follows.
Case 1
advertiser’s registered
「不動産」
“real estate”
user’s search term
「東京　不動産」
“Tokyo real estate”
Case 2
advertiser’s registered
「東京　不動産」
“Tokyo real estate”
user’s search term
「東京　不動産」
“Tokyo real estate”
Case 3
advertiser’s registered
「不動産　東京」
“real estate Tokyo”
user’s search term
「東京　不動産」
“Tokyo real estate”
Case:
Ad will not be displayed
advertiser’s registered
「東京　不動産」
“Tokyo real estate”
user’s search term
「不動産」
“real estate”
Tips
	
If the divided search term of users is judged not to be related to the advertiser’s registered search keywords, the term will be excluded.
(e.g.) “automobile” will not be divided to “auto” and “mobile”
	
The dividing search term method will have some different ways of writing with_ Okuri-gana for spelling, half/full-width character, capital/non-capital letter and so on.
	
The order of search terms will have no effect in ad delivery.
	
The dividing method above is just an example at this point. We are planning further improvements.
