Make 2 of the websites mobile friendly

2 websites of same domain need to become mobile friendly which involves fixing errors on google search console and get indexed on google search engine and redesign few of the pages and stylesheet. secondly, for one of the websites, recipe (custom post type) posts need to be published on its Facebook page whenever anyone post any. thirdly, for one of the websites, "load more" button needs to be added. More recipe posts should be displayed upon clicking this button like a AJAX scroll down feature. other work to be done are - indexing pages on google search console, redesign pages for mobiles, adding Facebook plugin to share a post posted on the website into the website's facebook page and lastly adding a AJAX feature to load more recipes(posts) on the home pafe upon clicking the @Load more@ button
