It's a new year tonight and there's going to be a HUGE shift in Google's search results - 2016 keywords disappear and 2017 keywords replace them. Write as many "Best of 2017" as you possibly can for the next few months; I've done very well with them. They rank high and convert and are available in all niches.
For example: Best keyword research tools 2017, best affiliate programs 2017, wealth affiliate review 2017, how to make money online 2017, best niches 2017 and on and on and on.
Hope you take this advice!
