Always Use an Image on Posts - Even if It's the Same Image
It really does pay to take those few extra seconds to upload an image to any posts you make in your online writing. Even if that means that you have just one image that you use as your avatar image and as your generic posts image.
Multiple times people have researched into these things - studies that show that people will choose to read a post WITH an image over one that doesn't have an image.
It doesn't matter if you use the same image as your regular avatar and your generic post image, or if you have a different one - so long as you have an image for every post. Something, just something, to catch the eye of the idle, bored and random reader who is scanning through posts, looking for something to read.
Of course, your title also needs to be exciting and/or enticing, but the image will catch their eye first/soonest, making you ahead of the game!
It doesn't have to be the best picture in the whole world - just something! You can always change it later if you ever wish to do so, but get something soonest and use it every time. Never leave a post naked!
The posh end of this advice is that it's your branding and part of your marketing opportunities and efforts - but, for now, it's just a nice little image that might catch more readers' eyes!
