I'm pretty much satisfied that there are no substantial (if any) 'penalties' for having a .biz domain from an SEO perspective, but what I am more concerned about is people looking at the .biz domain and being turned off, hence in the results I fear having a lower CTR than usual. For example, if the site is no. 1 and is supposed to receive around 40% of total clicks, it might only receive 20% etc. Do you think there is any cause for concern here? Or are people getting a bit warmer to alternative TLDs, .biz in particular?
