Webpage APP visitor's mobile phone number crawling method
Firstly, the first one is actually the website or APP developer using the latest crawler technology to grab the visitor's mobile phone number, mainly by inserting a piece of code in the header of the website. However, this crawling method was soon suspected of infringing on privacy and being easily detected by Baidu and K station. In order to preserve the natural traffic of their own website, many webmasters gave up this operation.
The second is to cooperate with a formal big data operator agency. The principle is that when a visitor uses 4G mobile phone traffic to visit a website or APP, it will form a unique http report, the visitor’s mobile phone number, which websites have been visited, How long you stay can be calculated to finally get the visitor's demand model. Operators' agents then give feedback to companies with professional services in this area based on these needs, and call their marketing backstages to solve user needs. Because it is desensitized data to protect user privacy, the second user itself has a high conversion rate in this regard. Used by the majority of business owners. Centaline Big Data (V:jycg789)
