If you're a start-up and you're directing people to your blog, please, please, please make an obvious and easy link from the blog to your startup's homepage. Don't hide it in the sidebar, don't make the 'home' link on the blog go to the blog's homepage, don't waste the damn traffic.
Make it brainless for me to get from your blog to your startup's homepage.
Annoys me too.
I've been experimenting with placements and sizes since day 1. The buttons on the footer of each post are doing pretty well so far (but they're still a new edition).
date update: Turns out the referrals to hipmunk from the blog were practically tied for second highest ever, so perhaps we should just keep drawing attention to our funnel methods ;) Realizing you totally missed the next 2 links beside home (flights / hotels) was a good prompt to update that section. Thanks for that.
I do appreciate the feedback!
To the immediate right of "home," the links "flights" and "hotels" link to their respective searches, but thanks for the anecdotal evidence. I'll give it a tweak right now.
