how to protect our content?

lets say i write an free e-book , but some web copy it and change the link that direct to my website. what action I must take???

how if we find some web copy our content ( i think copy web content is all right as long as he provide back link to my web by type source below the post)?

Any tips to create pdf (what must include to ensure about our copyright, e.g., put our weblink in footer)?

thank you very much

 

You can not do much besides sending DMCA (USA) or EUCD ( Europe) to host or the owner since they are not copyrighted.

 

nothing , or at least its not worth it

 

There is not much you can do, as you see from all the other answers. I mean you can encrypt it with "smart assembly", and that will somewhat protect it i guess.

 

You can make use of copyscape website. They will ensure their your site contents are protected and it is not copied else wehre.
