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.

Where should I put the back button on my website?

Left: back button next to the primary button (not recommended). Right: back button above the form (good). Some forms or questionnaires appear across multiple pages and some people want to go back to check or change their answers.

What is the Back button on a webpage?

A back button in the browser lets you back-up to the copies of pages you visited previously. The web browser's back and next buttons work well with web sites that provide information that changes infrequently, such as news and shopping web sites.
