It isn’t wise to crowd people’s minds with lots of info all at once. They will soon forget what it was all about!

People’s length of concentration:

People go to church to hear a sermon, but after about 10-20 minutes their concentration fades. Depending of cause how good it was presented.
And with the internet, people’s attention span is even shorter. Much, much, shorter. Within seconds!

Grip people’s attention straight away:

With church talks: The best way to start is with a joke or funny incident. That perks people interest straight away. It conveys to them the talk is going to be fun…great… and not a lot of boring stuff. So they get all geared up to patiently listen to what may be said. And give the speaker the chance in the hopes he or she will make it good.
With the internet: Not only must your headline title and your sub-title be dynamic, you mustn’t waste people’s concentration span time… even throughout your post’s content.

Keep your post to one topic:

Get to the point right away. State what your topic is going to be, up front, so people know what they’re in for. And keep what you’re going to say simple and easy to understand.

And when explaining your topic:

During your talk or post, support that main topic, with no more than two basic facts. Those supporting facts and statistics act a witness and proof of what you are saying is in fact true.

And if you can support those facts or statistics with stories, or experience you or someone else had, all the better!

Have fun lining up your facts:

List what you would like to say beforehand. And put them in logical order. And then write them up in your blog.

Secretly chatter away to yourself while you type. (It’s good to have fun while you’re writing!) your sense of humour frees up your style of writing. Afterwards you can delete all the in between unnecessary dibble.

Don’t complicate the issue:

Don’t clutter people’s minds with too many facts. Rather make it interesting.

People may go away thinking your post or talk was fantastic. But if someone should ask them afterwards to repeat what they had heard, they tend-to-one will only remember one fact… two if you’re lucky.

Remember your supportive facts, to your main topic theme, are basically there to boost and impact people’s memory retention.

Memory retention:

…Is caused by emotional involvement.

And that you can do, by ‘painting’ a visionary picture in their minds, because people think in pictures.
Make those pictures emotional with colourful and sensational with action-packed words.
If you use photos or images, emotional impact is also caused by using contrasting warm and cool colours.
Simple and bold statements make more impact on the mind, than long-winded drawn-out sentences.

And don’t forget either, that humour and laughter is an emotional trigger. Jokes stay in peoples minds longer than a lot of facts!
