Prevent average users from copying content and pasting into their websites

[4RealLocal]

Please do not respond with a "you can't stop them" comment, I understand this.

Most of our pages have content that is duplicated across multiple domains. The recent Google algorithm update focused on penalizing pages that have duplicate content, and it could be one of the reasons that we have been seeing traffic loss.

I'm looking for some type of javascsript/php code that will help minimize this issue.If could be code that does not allow you to copy and paste the code without turning of javascript or a dialog box pops up and says "this content is copyright protected, anyone copying this content is subject to legal action"

I've found one script that might work http://www.ioncube.com/html_encoder.php

My questions are still the same:

1 What is the best method to achieve my objective?

2 Will this additional code affect how the webbots see our site and or affect rankings?

I know that anyone can figure out how to get the code, I am trying to mitigate by providing a warning about copyright infringement and making it more challenging to copy our content.

Please do not respond with a "you can't stop them" comment, etc, I understand this.

Thank you for your comments!

Another thing I've seen people use is Tynt at http://www.tynt.com/. If you copy and paste something, it automatically adds a "see more from" and the URL to the end of the copy text that shows up when you paste it.

A higher-level question is regarding HOW people are copying your content. Are they going to you website and copying and pasting it, or are they grabbing it from your RSS feed? If they're scraping it via RSS or a non-manual means, doing things with right-clicks won't help much.

I agree with Zachary.  The script is good but there is a workaround.  Post first.  I would also suggest adding some links to interior pages, and to add some branding keywords in your copy.

Scrappers are lazy enough they forget to read the whole article.

If someone wants the content, they will get it. You can't stop them without making your content uncrawlable or severely limiting the user experience.

As long as you are publishing the article first, I don't see a problem with the situation. Duplicated content is a problem, sure, but for those that duplicate it. Unless Google has a problem finding the original source, you're fine. This has happened in the past but is rare.

Have you noticed a measurable difference in a controlled study?
