Baidu bidding actual consumption is 20% higher than the budget. What is the purpose of this?

When I went to do the statistics today, I found that the money spent exceeded the budget. I heard from others that Baidu upgraded it yesterday. What does this mean? Is it a sense of accomplishment to sink it? I guess how much it exceeded? As for how high is 20%, I also pay attention to the account consumption every day. We set a budget of 4,500, but it exceeded it by more than 90 at most, not even 100. How could it be as high as 20%?

The budget is exceeded because of your keywords. Generally, there is a delay in this budget. Maybe there is a balance at the time, but later someone clicks on several high-priced keyword promotion links. However, Baidu's review is not so precise and will not be so accurate (people definitely hope that the consumption is as high as possible). When someone clicks on your order, fees will definitely be deducted. When Baidu's statistical background detects that the budget is insufficient, it has actually exceeded the plan. Based on the original reasons, plus these consumptions, it will naturally exceed the budget.

Some users also see that their account names do not reach the budget, but the background prompts that the balance is insufficient. . . Same principle. . . The reason for the delay was this situation for one day. The customer service said it was due to Baidu's backend upgrade, and then it was back to normal. Baidu is cheating you out of your money!
