The last type of post is actually pretty lame, Facebook milestones. For personal accounts milestones are a big deal (i.e. a wedding, a graduation, an anniversary, etc.) but for most companies saying that you have been open for 3 years just isn’t as interesting to your customers.
That is unless you can tell people why they should care. If you want your milestone stand out make sure to make your title story, and photo captivating. So next time you move offices, celebrate a retirement of a long time employee, or celebrate your 10th years in business give a 10% of coupon to all customers. I’m sure that will get people interested in your milestones. Also, if you want your milestone stand out make sure to make your title story, and photo captivating.
