I just banged out a new Classifieds Ads system for a new site. Quick question: should I make the links direct (raw), or use JavaScript? With JavaScript, clicks, etc. can be tracked. But I also think it's really nice to give advertisers the extra benefit of a raw link that search engines can see & understand. Btw - this is not like TLA or some of the systems that are designed *solely* for the G juice. This is designed for eyeballs & clicks primarily, but if you can get some SEO benefit out of it as well, why not? *cough shameless plug* PM me if you're interested. Rates starting at $1 for 15 days (Alexa Top 40k).
You can do both - ordinary hyperlinks with javascript bound to 'onclick' to count many times a link is clicked. This is quite common on php directories.
