Recently, Google Adsense has launched a new ad format that reduces the clickable active area. Previously, we found that the entire Google Adsense ad box was clickable, but after the reform, only the title bar and URL are clickable. This undoubtedly reduces the likelihood of clicks by fivefold, allowing for more precise targeting of people who truly need the ads. Compared to other ad networks, this is undoubtedly a great innovation. After Google Adsense introduced this new ad format, I specifically compared it with Baidu's topical promotion, Yahoo's targeted promotion, and some other ad networks such as Ali Mama (more accurately, an ad trading platform), Blog Ads, and ZaiGao, etc.
