There are many websites in the world; the latest statistics indicate around 65 or 70 million, excluding those that disappear every day. There are so many that if we visited a different site every day, we'd grow old and still wouldn’t reach half of them. Among these millions of sites, some engage in poor practices that only serve to drive visitors away with frustrating or intrusive tactics.

• Blocking Right-Click: This might seem beneficial to website owners who don’t want their content, whether images or text, copied. In reality, it sends a message to users saying, "Don't come back; you can’t copy anything here." Many users may just leave… even though this can be bypassed with a simple CTRL + C. However, millions of people don’t know this trick and will likely look for information elsewhere.
• Copying Content Without Citing the Source: When you read a text on any blog or website and copy it into Google, you’ll find many similar or identical results. This kind of behavior is said to make Google’s bots lower the site’s ranking, causing it to no longer appear in top positions.
• Multiple Ads: Ever noticed sites with endless pop-ups and ads? Some sites have scripts that trigger multiple pop-ups, sometimes covering the entire screen with an “Exit” button that’s hard to find amidst the clutter, along with countless banners. This can leave a terrible impression on users.
• Registration Requirement: Some users visit a site simply to find information. If they're forced to register to view content, they likely won’t return.
• Intros: Adding an intro isn’t always helpful. People want speed and to get straight to what they’re looking for. Many users, like me, don’t have the patience for intros and will simply return to the search engine, ignoring your site.
• Hidden Text: Have you ever searched for something, clicked a result, and found nothing related to your query? Some sites hide text with popular keywords to attract visitors but deliver irrelevant content. Instead of gaining visitors, they end up losing them because search engines remove such sites from search results once they discover the trick.
• Exit Pop-Ups: This poor practice involves a pop-up when you click the red X to close, with annoying prompts like "Do you really want to leave?" or "Thanks for visiting, come back soon!" These forced messages are highly unpleasant.
• Background Music: Imagine you're listening to your favorite music, or sitting in silence, or in an office, and suddenly enter a website with loud background music. This is not always terrible, but believe me, 50% of visitors will leave within 7 seconds because they don’t want the noise. Forced to choose between muting the sound or leaving the site, many opt to leave.
• Forced Return to Site: In my opinion, this is the worst tactic. You enter a site, and when you try to leave, you keep getting redirected back. You can only escape by quickly clicking “Back” multiple times or closing the tab. This will guarantee that the person never returns.

If you doubt this, try it yourself: create two websites on the same topic, implement one of these practices on one and not on the other, and check the visitor statistics after a month. You'll see what I’m talking about.

Hope this helps if you're looking to lose visitors.
