What kind of content can be duplicated but remains untraceable through search engines?

In the past, I utilized the alt attribute of images to generate text that could be copied to the clipboard:

The style attribute can conceal text, however, hidden text still remains and can be discovered using methods like indexOf or control-F.

Is there an alternative method to incorporate text when copying a selection?

Answer №1

Just a note: I had initially posted an answer to this question yesterday, but I ended up deleting it because I wasn't confident in my understanding of your query. However, after seeing the additional information you provided, I believe that my previous response may actually be what you are looking for. (If it's not the right solution, please do let me know and I'll remove it once again)

Here is an example of what could work:

This snippet should result in the text <span style='display:inline-block; width:0px; overflow:hidden; white-space:nowrap;'>copy me!</span> appearing as random content.

When viewed on a browser, the displayed text should be This is some random text.. Yet, if copied and pasted into Notepad, it will yield

This is some copy me!random text.
instead.

Answer №2

It seems like the key factor here is the alt attribute:

<img alt="Try to spot me!"/>

Although the above code is supposed to show the alt text, using methods such as control-F and indexOf() won't be able to locate it.

I'm not aiming to conceal this text completely, just make it undetectable by indexOf(). It's worth mentioning that using style="display:none;" will hinder this (the text won't be copied). If you really need to hide it, try using style="font-size:0;", as I discovered earlier on How can I write text that the clipboard sees but isn't visible?
