The question of website protection from robots (bots) is quite topical today. Why it’s important, and what methods do companies have to ensure their online resources are 100% safe and protected?
Let’s have a closer look at the problem.
You need to ensure the smooth running of your website, blog, forum and cloud server, with no load delay, downtime, and zero spam in the corporate database. It’s time to start thinking about protection from robots. Taking into account, the majority of your traffic is from referrals, and 60% of the referrals are robot-generated, then cleantalk.org website spam protection is of high importance.
Spam Protection Methods
There are many different methods aimed at protecting your website from bots. However, far from every approach is effective. So let’s take a look at the best ways of safeguarding your platform.
#1 – Time for Filling out the Form
This method is associated with the server tracking the time a user spends on submitting a form. If the user has filled out a form in less than a certain time, he is considered a bot. You can set up such limitations allowing you to filter the traffic. The time can vary depending on the complexity of the form.
#2 – Hidden Field
Although this method may seem strange to some, it works effectively. A hidden field is added to the form; an ordinary user will not be able to see the entity. However, a robot, which accesses the page code, will identify the hidden field. If that field is filled out, the user is considered a bot and this gets blocked.
#3 – HTML Encryption
The page source code is a set of javascript functions like document.write (decode (encoded HTML)), where encoded HTML is somehow encrypted HTML. Encryption methods can range from simple escaping of some values or letters to some encryption algorithms (for example, a simple XOR).
#4 – Create a “Trap” for Bots
All you need do is create a special section on the website, such as “/bot/guestbook.” The link to this section is not visible to the human user; however, if the bot enters this section and does at least something there, then its IP is immediately identified and blocked. The section for robot detection should contain bot-friendly words like “email,” “submit,” “add a comment,” etc.
#5 – Hashing Form
When submitting a form to the server, a hash of the form fields is calculated and added to one of the special hidden fields. The server checks the hash value.
Important Notes
The above methods are not universal protection tools from bots. They will not save you from 100% of direct attacks, but, they will significantly reduce the risks of your online website being hacked. It’s advisable not to save money on safety and make sure any of the above methods are employed for your website.
