Most Social Media and many blogs include a lot of selfies. Do you have to have selfies?
No. You don’t have to do anything you don’t want to do. I have extremely few selfies on my Social Media and I don’t remember any photos of me at all on all but one of my blogs.
But, there are good reasons to have some photos of you on your site. Photos with faces boost engagement up to 40%. And if you are going to include your photos, you want to look good.
