The 28-year-old Scot recently penned a new one-year deal with the Seasiders.
"I had a few options to be fair," he told the Blackpool Gazette. "The amount of clubs interested was the main reason for me taking my time to make a decision.
"I spent the summer speaking to people, and am really happy to be back at Blackpool."
Broadfoot arrived at the club on a free transfer from Rangers in August 2012.
