Posting a photo with your social post will nearly always create more user engagement. Your chances of getting liked, shared, or retweeted increases dramatically.
Using a professional photographer for your website is always recommended. When posting on social it is not always cost effective, timely, or as important. Of course, there are exceptions but for the most part your smart phone will perform well.
All photographs should be well lit and composed properly. Your brand should be shown in a beneficial manner. When not using a professional or stock images you must always be aware of what is in your background. Your photos are representing your business and not your lifestyle.
Yes, any newer iPhone or Android style phone is more than adequate to post random or casual shots with. The quality of cameras on these phones is greater than what most mid-range point and shoots were a year ago. Smart phones also give you extreme flexibility for posting on the go or editing in a coffee shop, etc.
There are many software applications to adjust, crop, and stylize your photos with before posting to a social network. The rule should be — just to find one you're comfortable with and learn to use it proficiently. Make your photos look real and relevant. Funky angles, over-saturation, dimly lit, blurred or shaky images represent a degree of amateurism and will not represent your brand well.
In almost all cases it is beneficial to tag people and companies in your posts. Tagging people or companies relevant to the post you are creating will notify their followers about the recent activity. This will create a higher reach for you and for them. This is a win-win for all and what the essence of social networking is all about.
If for some reason, someone declines to be photographed or tagged you should oblige by their wish. In some instances that person may be asked if they could be the photographer and let you be included in a post that you would otherwise not be included in.
Unless you are creating a meme, you should keep any text overlays to a minimum. Let the image speak for itself. Utilizing 20% or less text over the image is a standard amount.
If your company uses text overlays on an image you may encounter issues getting your post approved on Facebook advertising campaigns. Facebook allows minimal texts on images but there is some speculation that those images are penalized during the bidding process.
Here are a few quick etiquette tips when posting to social, especially on a company account.
When posting photos to your company Facebook page, first post to Instagram and from there you will be able to automatically share it on your Facebook Page.
Have a friend or colleague proof your photo before you post it. They may catch something that you didn't. Three (3) seconds to proof sure beats a retraction and explanation.
