Like many SEOs, I was hired with one vague responsibility: to set up an SEO program and achieve results. Like many SEOs, we jumped right in and started spewing out SEO audits, rewriting title tags, offering up link suggestions, rewriting URLs and so on. And like many SEOs we promised results. But what we didn’t do, until that fateful launch, was develop a comprehensive strategy.
As I had a teacher at school who was always really picky on how to draw conclusions I must say that the conclusions you drew for your health situation might be true, but dangerous. For example: If slightly more women than men suffer from health deseases it could be wise to write the information toward women. But, if you take search behaviour into account thing could look a lot different: It might turn up that men search more than women or that (senior) men are more present on the net than women.
Hey Ted, thanks for the great questions! The peak times refer to your particular time zone, if you are targeting an audience that resides in the same zone as you. You can also use tools to find out when most of your audience is online. For example, Facebook has this built into their Page Insights. For Twitter, you can use https://followerwonk.com/. Many social posting tools also offer this functionality.
