If you’re looking to take a day off from posting on Facebook, choose Wednesday, but don’t rest on Sunday or you’ll miss the best opportunity of the week.Weekends, when brands post too little, the audience appears primed for interaction, though it varies by industry.Not very good news for corporate Social Media teams.

Best time of the day to post.

• Facebook’s highest traffic peeks between 1pm to 3pm. 
• Traffic starts to increase from 9am, but consider waiting to 11am to start posting as it would receive higher traffic. 

Meanwhile, when it comes to posts, less is more. Brands that post one or two times a day see 19% higher interaction rates than those that publish three or more posts. The key is not to bombard fans with too many posts.They will get bored and Facebook mostly de-optimizes your feed.

Also note:

• Use links with a recognizable URL, like “www.shop.com/umbrellas” where users have an idea of what to expect.
• Asking a question is a good idea, but ask it at the end of your comment, not at the beginning. Posts with a question at the end have a 15% higher overall interaction rate and a 2X higher comment rate than those with a question asked in the middle of the post.
• Ask fans to caption a picture. Posts that ask readers to “caption this” get 5.5X higher comment rates than average. Such posts also increase the overall interaction rate by more than 100%.
• “Fill in the blank” is another good option. Such posts garner 4X more comments than average.
• Use emoticons: Posts that contain emoticons receive 52% higher interaction rates. Posts that employ them have a 57% higher like rate,a 33% higher comment rate and 33% higher share rate.
• The best emoticons to use: “:D” and “:P.” Such emoticons have a 2.4X and 2X higher response rate, respectively than other emoticons.
• Use a call to action. Posts with commands like “Like,” “Caption This,” “Share,” “Yes or No” and “True or False” get interaction rates that are 48% higher than average.
