Most importantly, invite them to share on your page. If you don’t ask, you aren’t likely to get them. Not because people aren’t interested, necessarily, but people are busy and don’t always think about it. Don’t be shy! And don’t forget to return the love. Be sure to take the time to like pages when asked if they are a good fit for you.
