In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a flowchart of a method for estimating a conversion rate of getting guests in an embodiment of the present invention is shown. The method specifically comprises the following steps:
and 11, acquiring user information of a second link in the business links.
In a specific implementation, the user information may include at least one of: the age of the user, the gender of the user, the occupation of the user, the operational record of the user, the historical purchase record of the user, and the like. It can be understood that the user information may also include other contents according to different actual service scenarios, which are not described herein again.

In a specific implementation, the guest conversion information may be a guest conversion condition. When the audience is converted into the client, the guest obtaining conversion information may be represented by 1, and when the audience is not converted into the client, the guest obtaining conversion information may be represented by 0.
For example, when the ith training sample is converted into a client in the nth link, the client obtaining conversion information of the ith training sample in the 1 st to the N service links is all 1.
For another example, when the ith training sample is not converted into a client in the nth link, the client obtaining conversion information of the ith training sample in the nth business link is 0.

And step 13, obtaining and outputting the estimated result of the passenger obtaining conversion rate.
In a specific implementation, the estimated result of the customer-obtaining conversion rate may be a probability of converting into a customer, and may also be a scoring result. For example, the estimated customer conversion rate is 0.9, i.e., the probability of conversion to customers is 0.9. As another example, the estimated conversion was 85 points. And outputting the obtained estimated result of the passenger obtaining conversion rate.
According to the scheme, the customer-obtaining conversion rate model used for estimating the customer-obtaining conversion rate is generated through the following steps: the method comprises the steps of obtaining a first pre-estimation model based on link information training of a first link in business links, and obtaining the first pre-estimation model by adopting link information of a second link to continue training the first pre-estimation model, so that when the customer-obtaining conversion rate is pre-estimated, the influence of the first link on the customer-obtaining conversion rate of the second link can be considered due to the fact that the first link is a front link of the second link, and therefore the pre-estimation precision of the customer-obtaining conversion rate can be improved.
In specific implementation, after the customer-obtaining conversion rate estimation result is obtained, when the customer-obtaining conversion rate estimation result meets a preset condition, corresponding operation can be executed.
For example, when business marketing is performed, the first link selects the short message to reply, and can preferentially send the marketing short message to the user with the estimated result of the customer-obtaining conversion rate higher than 0.6, so that marketing can be performed more specifically, the marketing success rate is high, casual and non-purpose marketing can be avoided, and the marketing cost is reduced.
