Many blogs have two audiences, sometimes equally divided, sometimes not: The daily readers and the visitors through links and search engines. But most of us treat those visitors the same – presenting them the same layout, and the same amount advertisement. Why?
If you analyze your earnings, you should see a difference between profit from your daily blog readers and visitors through links and search engines. It is because of their different focus in attention.
Daily readers ‘know’ your layout and will get very blind on advertisement. The other group is searching for something particular, and therefore is very open to contextual advertisement. Daily readers get annoyed by too much advertising (even when it is contextual), and the other group loves them.
But as you would like to earn money, there is no way to please the daily readers … or? There is. Think about it one second. What is the difference between both groups?
It is the amount of time since you published the article.
If your blog is listed good on search engines, it will at least take some hours to fetch your new article and often take a day to rank you. Your rank for an article slowly rises, so it is save to assume, that while your daily readers are through with your blog in a week, search engine and link traffic will start after a week.
So my suggestion is: Start showing advertisement if an article is more than some days old! This will need some programming you might not be able to do of your own, but someone can do for you.
Or: you can use such mechanism to display different ads based on the age of the post or gather more information how your website performs at the different times slots.
With this you get happy daily readers and still profits from your websites!
