Comment on SEO Recent Posts WordPress Widget by Mark.
In fact people often have a header something to the effect ‘Click here to see a Random post’.
I use an old Matt Mullenweg Random Redirect plugin to do this. the plugin works great, just by adding an image link to a text widget.
The problem is unless you are a very graphical website it does not seem to increase page views as hoped. I think the reason is, people go to a website looking for specific information, not random information.
However, if you have a website like the ‘cutest horses’ it might work as people do not mind clicking to see random photos of cuteness.
Great idea but with a narrow focus, that is image websites, unless I do not know how to leverage this for more article based sites.
