How to effectively block "malicious clicks"

For semer, no matter whether you are a newbie or veteran, how perfect your account structure is, how high the quality of keywords and creativity is, as long as there are malicious clicks from peers, the promotion cost, which was originally saved by great hardships, was increased even though Baidu had a filter.

 

For semer, no matter whether you are a newbie or veteran, how perfect your account structure is, how high the quality of keywords and creativity is, as long as there are malicious clicks from peers, the promotion cost was reduced by a great deal of hardships. although Baidu has the invalid click filter function, its "cunning" peers can always come up with a solution.

In serious cases, my budget was exhausted by noon, and I personally experienced it. at that time, I was speechless and angry. The only thing we can do is shield the IP addresses that maliciously click (there are blocking items in the Baidu promotion background), but the IP address will change. Today, an IP address is blocked, and it may not be the IP address tomorrow, fortunately, some special IP addresses remain unchanged (for example, VPN proxy servers). some IP addresses, even if they have changed, can follow the rules.

Because I am a technical engineer, I have obtained the IP address Statistics database of my website (which can be written by your company's web developers, which is very simple ), after a long period of data observation and enduring unnecessary "cost" overhead, I have summarized two methods to cope with "malicious clicks". At present, I can say with certainty that, at least half of malicious clicks are reduced.

First, your website must have its own IP address Statistics database, and then install Baidu Statistics. Baidu Statistics has a pity that you cannot see the visitor IP address, so you have to install 51la or cnzz. There are three in total, and they don't bring any load to the server. Don't worry, because Baidu Statistics, 51la, and cnzz are obtained based on the client's javascript, not through the web server. The following are my methods:

1. malicious clicks on unchanged IP addresses:

This is the access record of the same IP address in my IP database. when I find that such an IP address exists, I will go to Baidu Statistics and 51la access details to view visitor features, if you change many keywords, block them. However, if this IP address cannot be found in 51la and exceeds the maximum number of records that can be saved, you only need to scan Port 1723 of this IP address (online scanning is available on the Internet, you can also directly use the php socket). If this port is open, block it. It can be imagined that this peer is really "sinister", and even vpn proxy is used (what is vpn proxy? If the port is not open, remember this IP address first. when it appears again, check its characteristics through Baidu Statistics before making a decision. after all, we do not want to "kill" the innocent. The above process can be automated. for example, if an IP address opened on port 1723 comes in, an Email is sent to the owner. Because the proxy servers that can be used by peers are limited, as long as there is more Shield, they can't help you.

2. malicious clicks on changed IP addresses:

In this case, you must have sufficient access to data as a prerequisite and be patient. In general, even if your bandwidth ip address changes, it only changes slightly in the third or fourth segment of the IP address. It takes a long time to observe the visitor characteristics of each incoming IP address. if suspicious IP addresses are found, such as 118.244.150.143, for SQL queries like "118.244.150. * "or" 118.244.1 * ". if there are many records in the query results, you have to pay attention to it. you can scan its port 1723 and Baidu's IP address, check whether a peer has used this similar IP address to publish information. in this way, I found an IP address from the previous click record. on the same day, a peer has used this IP address to publish information, this determines what this type of malicious click is. This is part of the record before I found a malicious click:

What should we do when we are determined to be in the same industry? block it.

In 2nd cases, it is really hard. if you do not have a dedicated person to watch, don't do it. However, to check whether the vpn proxy has at least some functions, you can find a developer in one day.

In fact, the best way is to save money and effort, compete fairly, and focus on products and services, rather than doing such meaningless things.

I hope that people who have read this article can save on the cost and work together to build a harmonious Baidu promotion ecosystem, refuse to click maliciously, and start from me.
