Many blogs have begun using the infinite scroll which means their blog posts go on endlessly, bottomless. It may be good for keeping people reading your site longer, preventing bounces. But… please throw your readers a lifeline – add a link back to the top of your site.
I was reading WP Decoder earlier and sent a note:
With infinite scrolling it would also be nice if people provided a floating link to get back to the top/ start. I wanted to look for your Twitter link after reading far down your bottomless posts. (I was in 2013). Not everyone knows basic things like keyboard shortcuts these days.
A floating link is best because it will stick with people as they read. Plus, it jumps around a bit and tends to get noticed.
