It's suggested that on average Page administrator's should spent between 4-10 hours per week updating, creating content for, and managing their Facebook Page. This however depends heavily on the popularity and online activity of the brand.
You can, in fact, reach certain users who are not yet engaged with your Facebook business page. Organically because of Facebook's EdgeRank algorithm, a page's posts will only reach about 16% of your fans' news feeds. But Promoted Posts are not only engineered to show up in a larger percentage of your current fans' news feeds. In fact, when one of your fans interacts with (i.e. clicked/commented on, shared, liked, etc.) your Promoted Post, it will also show up in the in the feeds of their friends, even if those friends aren't directly fans of your page. The post that would show up in these second-degree connections' news feeds would show the interaction between the fan and your business page.
Facebook defines the viral reach of a post on Facebook as the number of unique people who saw one of your posts through a story that was published by a fan of your page . Facebook's explanation notes that the stories in question can include liking, commenting on, or sharing the post, responding to a question, or responding to an event. The number of friends per fan who see the story in their respective news feeds is then calculated to determine each post's viral reach.
First things first. There are quite a few little things you should take care of (such as making sure the information on your page is complete, accurate, concise, and includes a link to your business's website) to ensure that your page is well-optimized and engaging in order to attract more likes. But in addition to the low-hanging fruit, to truly increase your Facebook page's social reach and attract more fans, you need to do much more. Some guaranteed ways to do this include sharing useful, valuable content regularly; promoting your presence via your website and other marketing channels (think other social accounts, email marketing, etc.); adding social plugins and sharing buttons to your website and all your content; building relationships with industry influences; interacting with current fans; and offering incentives for new fans.
If you are operating within a truly bilingual market, the best course of action we can recommend is maintaining two separate Facebook pages for your business, if possible, noting in the page's vanity URL the language for the page. The pages can certainly be cross-promoted, and both should be linked to via social plugins on your company's website. Take care to maintain both pages equally, but also pay attention to which types of posts resonate with the audiences of each page.
