YouTube is a popular platform with over 2 billion monthly active users as of 2021, making it an excellent platform for businesses to advertise their products and services. Since YouTube opened its doors to advertisers in 2007, the number of ads has increased tenfold. Businesses can use several types of YouTube ads to reach their target audience and build brand awareness.

1. The first type of YouTube ad is the Display Ad, which is the most basic type of ad. These ads are small banners on the screen’s right-hand side, above the video suggestions list. They are relatively unobtrusive and do not interfere with the viewer’s video-watching experience. Display ads can build brand awareness and drive traffic to your website.
2. The second type of ad is the Overlay Ad, which appears at the bottom of the video and covers a small portion of the screen. They are semi-transparent and can be closed by the viewer. Brands can use overlay ads to promote a product or service or to direct viewers to your website.
3. Skippable In-Stream Ads: They are the most common type of YouTube ad, which can appear before, during, or after a video, and can be skipped by the viewer after five seconds. These ads can be up to three minutes long, but keeping them between 15 and 30 seconds is recommended. They are an excellent way to build brand awareness and promote products or services. One of the perks of this type of YouTube ad is that you will only get charged when someone watches at least 30 seconds, the entire ad (for any ad less than 30 seconds), or if they click on it. These ads will run by many companies such as http://buyyoutubeviewsindia.in.
4. Non-Skippable In-Stream Ads are similar to skippable in-stream ads, but the viewer cannot skip them. They can be up to 15 seconds long and are typically used for shorter ads. Non-skippable in-stream ads can be a good option for promoting time-sensitive offers or products. These ads can play right before a video or during it, but the only difference is that there is no skip button. Considering that a high percentage, some 76% of people, skip the ads that get served in YouTube videos, the non-skippable ad is best when your brand needs to raise awareness and wants to avoid getting hundreds and thousands of ad skips. The way that these ads charge brands is a little bit different; charges are incurred per impression, more specifically, per 1000 views (CPM).
5. Bumper Ads are another type of non-skippable in-stream ad, but they are only six seconds long. They are designed to be short and to the point and cannot be skipped. Bumper ads are an excellent way to build brand awareness and promote products or services quickly. These ads are perfect for anyone who has a simple message to get across and only needs part production of a minutes-long video. If you think a 6-second spot seems too short to make a lasting impact you might not be right,as Google analyzed 300 bumper ads and found that 90% created a significant lift in ad recall.
6. Sponsored Cards are a type of ad that appears during a video. They are small cards that display additional information about a product or service, and they can be clicked on to visit a website or watch another video. Sponsored cards are relatively relaxed but can be an excellent way to promote products or services.

7. Sponsored Content is a type of ad created by a YouTube creator, not the brand. The creator will promote the brand’s product or service in their video, and they will disclose that it is sponsored Content. Sponsored Content can be an excellent way to reach a new audience and build brand awareness.
8. Masthead ads are a type of YouTube ad situated at the top of the YouTube homepage and are only available to big brands with significant budgets due to their high cost. However, they are an effective way to build brand recognition and reach a broad audience quickly.
9. Discovery ads are another type of YouTube ad similar to display ads but appear more prominently in search results and related video suggestions. These ads can be clicked on to watch the video and are an excellent way to promote products or services and increase website traffic. These ads are distinct from other YouTube ads and function more like Google search ads. They consist of a thumbnail image and three lines of text and are labelled as “Ads” to differentiate them from organic search results. Discovery ads can appear on the search results page, video watch page, and YouTube homepage, making them highly visible.
10. Outstream ads are a type of ad displayed on partner websites and mobile apps and are part of the YouTube advertising network. These ads do not appear on the YouTube platform itself.
11. For brands that do not have a large budget for video ads, YouTube also offers non-video ads, including display ads on the right-hand side of search results and banner ads that pop up during a video. These non-video ads charge based on a cost-per-click basis.

So there are many different types and formats which youtubers can use effectively to monetize their channels, and brands can use to promote themselves through youtube platform.
