Why is the actual effect of Baidu's phrase precise inclusion different from the theory?

We all know Baidu's three phrase matching methods, namely, exact phrase inclusion, phrase core, and phrase synonym matching. From Baidu's conceptual point of view, it means precise matching from phrases to the core. The more keywords can be covered, the lower the accuracy. But it is better than broad match, at least the matched user search terms are somewhat related to the account keywords. Let’s take a look together with Dongguan Internet Promotion Editor!

Why is the actual effect of Baidu's phrase precise inclusion different from the theory?

Recently, the editor started a new air ticket project. Since it was a brand project, I simply gave reasonable bids and precise phrase inclusions to thousands of keywords based on experience, and then just threw it there to run the data. I plan to wait for half a month to see how CPC and CTR are optimized. It is understandable that the CTR of a newly launched project is low, for example, the keywords have not all passed the review, the keyword quality has not yet accumulated, and so on. But it is hard to understand why the click-through rate has been below 1% for the past week.

Since I gave the exact inclusion of the phrase and the overall ranking is not bad, why is it like this? What words brought it about? The results are as shown in the figure below.

The editor said that most of the users who search for these place names are trying to understand the local characteristics, and they are definitely not trying to book air tickets. But the phrase I set contains exactly, why is this the case? The definition is as follows:

Therefore, in the actual promotion process, many basic concepts of Baidu are completely wrong. This requires us to always grasp the account promotion situation and correct problems in time when they arise. Don't stick to Baidu's theoretical basis. This is why actual combat is the criterion for testing the truth, not what can be learned through training and books.
