Do you need a captcha on your website?

[subornaakter20]

Spammers are always on the alert, so captcha is an attractive solution for web resource owners. Tracking and deleting spam manually is a time-consuming and labor-intensive task. With captcha, logging into a site will take users a couple of minutes, but such time expenditures are incomparable with the administrator constantly cleaning the site manually.

Captcha is becoming more popular and is direct moving leads email list used on the Internet more and more often. The reCAPTCHA project presented statistics according to which approximately 200,000,000 recaptchas are generated and checked every day. The time it takes a visitor to enter a captcha is about ten seconds. The Drupal CAPTCHA project says that, according to its data, captcha is used 100,000 times per week. And these figures are only from those sites that send reports to Drupal CAPTCHA, and there are many more Internet resources that have installed captcha.

Captcha for a website is in demand among administrators because it solves the spam issue well. At the same time, real visitors to web resources usually pass the check without any particular difficulties. That is, for the user, captcha ideally does not represent some insurmountable obstacle.

However, captcha is still a problem at times. According to W3C, in a number of systems, captcha readability is 90 percent. At the same time, hypothetical losses due to this obstacle are equal to approximately three percent of users - this is how many customers do not go to the target pages because of captcha and then leave the resource altogether.

Most website owners make their profits from users clicking on their landing pages. So these losses are significant for them because they reduce sales.

The situation with captcha was assessed in a global study called "How well do people cope with CAPTCHA? A detailed assessment of the situation." It was released by American specialists working at Stanford University. It presented, in particular, data that users spend about 28.4 seconds to solve audio captcha. Plus, the problem of solving captcha in a language not native to the visitor was described.

Tim Kedlek, a well-known web design specialist, generally talks about the disappearance of such a phenomenon as captcha in the future. He considers the protection of a site entirely the problem of its owners and is perplexed why ordinary users should spend their time and energy solving someone else's problem. Let administrators deal with the spam problem themselves, without involving visitors.

At first glance, a simple captcha for a website turns out to be not such a harmless tool, which is confirmed by the W3C report we wrote about above. Using a captcha would be unfair and difficult in relation to, for example, people with sensory impairments, poor eyesight, etc. And they are also Internet users, spending their time and money there, so their features should be taken into account.

In relation to captcha, website owners are currently facing two pressing questions. The first is whether captcha is really so inconvenient and unacceptable for customers that it should be abandoned? The second is whether there is a captcha in nature that is difficult to crack but easy to read? If the owner of a web resource answers both questions negatively, then the problem with captcha is really urgent.
