Great post, your knowledge and innovative approach never fails to amaze me! This is certainly the first time I’ve heard someone suggest the Wikipedia dead link technique. It’s great that you’re getting people to think outside of the box. Pages like reddit are great for getting keywords and can also be used for link building although this can be difficult to get right. Even if you don’t succeed at using it to link build it’s still a really valuable platform for getting useful information. Thanks!
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.
