6. Paragraphs:

It's no fun to find a screen full of text. Have you divided your text into paragraphs?

A paragraph should be between the 5 and 12 lines.
You scare people off with a block text of 60 lines in a row

7. Amount of words:

When you have less than 500 words that means you are in the wrong business,
the bare minimum is 750, anyway, I question you will pull in a great deal of movement with that, it depends where you are writing about.
1000 words will make you tickle the interest and more will make you fascinating for Google, Bing, and Yahoo. When you exceed the 3500 words, consider to write an e-book.

8. Images and Pictures:

Don't use your keyword as alt tag in an image unless is't appropriate.
Images and pictures you name for what they are in the alt tag.
You want visitors to find your article via Google image search too.
Be creative in finding alt tags in Jaaxy.

eg: When your keyword is Magic Bullet blender, and your photo is from a magic Bullet blender,
you can use the keyword phrase "Where can I buy magic bullet blender?"
But when your keyword is, "How to lose weight?
Don't call your Magic Blender after your keyword phrase because it does not fit your image.

9. The fold:

Does your first image appear above the fold?
Above the fold is what people see on their screen without scrolling.
It's also not advisible to put a video above the fold,
it can delay the loading time of your webpage.
Check in preview what people see without scrolling.

10. More about visuals:

Optimize your images before uploading them.
Have you resized and renamed your images before uploading? Resize to max 900px.
That's about the amount of px width your blogroll has. When you intent to use a much smaller size, resize it to 300px
Have you linked your images to additional info? A product or a special website? If not, you need to set them to "none". When you let the open into a Media File, you will loose visitors over it.
Other visuals: You can choose to add a YouTube video or an infographic too.
