What is Frame-Busting /Frame-killer

What are Frames used for?
HTML frames (FRAMESETs and IFRAMEs) are a feature of all modern web browsers that enable content from multiple pages to be displayed within a single view. Historically, frames were primarily used to enable partial page updates, where page navigation was contained in one frame, and page content was contained in another. Over time, use of frames expanded to include advertising, mashup, and AJAX scenarios. Today, the majority of popular websites use IFRAMEs for various reasons.

What is Frame Busting?
A framebusting page is a web page that will open your page within a frame from an "external" web page.
What actually happens is your site is aggregated, which is ok, but there is more to it, they will start framing your website and will show "ads" , like they run google adsense beside the pages they stole from you,which is not good. So its your content, he stole your content and added google adsense and all the revenue will go to him.
Besides, your website's pagerank may go down, and I imagine all the stats tagged to google analytics will drop. Also, I read somewhere that it is against the Adsense TOS (Terms of Service).
So essentially they benefit from your content.

How to bust them?
Solution is simple.
Add Frame Busting code, add these three lines of code and it will fix it.
the basic idea is :
if (your site is in someone else's frameset)
{ top frame location = your frameset/homepage}


<script type="text/javascript">
if(top.location != location)
{
top.location.href = document.location.href;
}
</script>

So you have to find out if your site is framed, and if it is you should change the top frame location. Finding out if you're framed is easy, but changing the top frame location is not allowed in Safari, even though all other browsers support it.

That is all it takes to "bust" out of a frame and ensure your site is displayed on top.
