autopost or manual post (difference)

Hey guys, so I've been doing abit of a research in starting a fanpage for one of my websites. My goal is to create a fan page, buy some likes, and start posting 30-40 pictures each day. My original goal was to get an autoposter app that will auto post pictures every 20-30 minutes. I heard some drawbacks about autposting that it can kill a large number of insights so manually is preferred. So I want to get some feedbacks if I should actually hire somebody to manual post for me daily, or install the autoposting app. Thanks in advance guys

hiring somebody may be dangerous a little, I hired someone and he spammed the page with his links.
you can use hootsuite, first month will be free

Auto posting is fine but don't spam people to death .set a good interval between posts. on my pages I usually post 1 picture every 3 hours. depends on your page. do some tests and see what works.

Take care with Autopost coz if you keep on sharing same primary url too much, your url will be banned.

If you're autoposting, set the intervals properly. People don't want to see your shared posts every minute.
