Here is a question I seem to answer a lot: how do you change the content in your footer?
The footer is the bottom of your website -the part that usually shows on the bottom of every page. It’s the counterpart to the header (the part of your site that shows at the top of every page).
Often your footer will contain some contact information and possibly also a button, a menu (some links), a widget (recent posts) and some live feeds (Facebook, Twitter).
On most WordPress sites, you will want to look for the Widgets section under Appearance in the dashboard to edit your footer.
Then, look for some dropdowns with Footer in the title.
