I have started using a new method for tracking clicks to hardlinks on my sites and it works great so I thought I should share the method here.
Code:
<a href="http://hardlinktrader.com" title="Trade Hard Links" target="_blank" onmousedown="this.href='/tp/out.php?link=hardlinks&to=hardlinktrader.com'; return false;">Hard Link Trader</a>
Basically... for a search engine spider, this looks like a hard link... but when a surfer clicks on this link he is sent through the trade script just like a toplist click. It is the same method that google uses in it's results.
