How can I increase organic search CTR?

Writing for SEO can often seem like a daunting task. To make things a little easier, here's a quick digest of some in depth research into what drives the highest click though rates in organic search.

1. Position is all important. Higher position = higher CTR
2. Title tags that contain a question have a higher CTR
3. Title tags between 15 to 40 characters have the highest CTR
4. URLs that contain a keyword have a higher click through rate
