The main heading of your page tells visitors, including search engines, what the page is about. Heading tags let us mark up what is a heading or sub-heading on the page, and we can use the h1 tag to show the primary header. Most CMSs do this automatically. Lists are very easy to follow, and they make all the information included very easy to digest. It may not be a good idea to link to the website from footers or sidebars. Instagram does not have the ability to link to a website from individual posts.
