Evergreen content. It’s what many bloggers crave. Posts that keep people coming back. Passive traffic that you don’t have to do anything more to receive.
Back-in-the-day we called this the longtail. Publish enough posts on a given niche and generate tons of traffic over the longterm due to people searching for those topics and your blog becoming a valued resource.
The problem is that it is crap traffic for a personal blogger. It is someone in a moment of need of a piece of information and they are looking for it via your site. It isn’t reflective of your audience size, it isn’t someone that is interested in your opinion or perspective, it is just someone that jammed their fingers in the right order on Google and found your site.
I have a post here on my blog that generates ridiculous amounts of traffic. It skews every number in my analytics. None of those thousands and thousands of people ever come back to my site. Very few even click around. I’m glad people are finding my solution to that particular issue but other than that it provides me no value at all.
That being said, if I was a professional blogger that wanted to make a living at writing I’d be all over it as it is the best traffic for generating money via advertising.
