I believe my store is running slow due to coding still being on my website from old, uninstalled apps. I try my best to remove the codes, but sometimes I overlook them or may delete the wrong thing. I try to reach out to the developers, but sometimes I get no response and I still have coding from super old apps when I first launched my store. Any suggestions on how to properly "clean" my website or tips for the slow page speed? At this point I am ready to hire somebody, but who? HELP!
