I recently noticed in my log-files that certain expressions I use in the plain text can have another meaning which I didn’t consider. When I say "Spring fashion: Women are wearing xyz this spring", Google directs all the men to my page who are sexually attracted to women in xyz.
To write a word backwards in the text and display the letters from right to left, in order to display them in the right direction, i.e. readable for human beings, has been used to encrypt mail-addresses and it is a good way to avoid the word being indexed.
.encrypt { unicode-bidi: bidi-override; direction: rtl; }
HTML:
You are talking <span class="encrypt">tihs</span>, but I love you.
I can’t garantee that "tihs" means something awful in Albanian.
By the way: Does anyone know a way to prevent single images from being indexed? (except empty alt-attributes)
