Placing ads directly below titles such as these implies to your users that the links in the ads are publisher-created content. The example below shows a placement that does not follow this guideline.
2. Ads should be easily distinguishable from surrounding content.
広告は、回りのコンテンツから容易に識別できなければいけません。
Similarly, you should not place an ad unit by a group of links that has identical colors and line spacing. Doing so may cause users to think the ad unit is content created by you.
In this situation, we recommend using a different color for the ad titles or indenting the ad unit to help distinguish the ads from your own content. This screenshot shows an implementation that does not follow this guideline:
As you can imagine, users who click on ads that they think are publisher-created content may lose trust in your site and decide not to return in the future. It's important to keep their interests in mind, as well as your own.
Also, advertisers can tell which sites have a high conversion rate for them using Placement Performance reports.
また、広告主はどのサイトの広告でコンバージョンが高いかをレポートで見ることができます。
A conversion occurs when a click on an ad leads directly to user behavior that the advertiser deems valuable, such as a purchase, sign-up, page view, or lead.
コンバージョンは、広告主が望む行動を広告をクリックした人が起こしたときにカウントされます。
Advertisers have the option to exclude your site from their campaigns and may do so if it is not leading to conversions.
