When should back to top button appear?

Back to top buttons are necessary for web pages with continuous scrolling, or a page that includes a long amount of content. A good guideline is to include a Back to top button for any web page that is longer than 4 screens.

Where should back button be placed?

Place a persistent Back to Top button in the lower right side of the page. This is where people expect to see it. This position is out of the way, but noticeable. When the button is placed in a different place on the screen, it is often ignored.

Is infinite scroll SEO friendly?
