Start With Photos
Write a Caption for each photo as you Upload Files into WordPress.
Put the photos on the page in a logical manner.
Using the Caption, add more information in a paragraph below each photo.
Tell a Story
This is a popular blog format. It works great for Travel Blogs and other personal experience blogs.
I find this the easiest format to work with when talking about a product. I often start with why I was looking for the product. So sometimes it is a Problem/Solution story. Often it is just a Look at this Cool Thing story.
What is the Call to Action?
What do you want the reader to do next?
If you are selling a product, make it easy to buy the product.
If you have a service, make it easy to contact you.
Suggest the next page to read to increase your ad revenue.
Why Bulleted Lists?
People are most likely to just scan web pages. A bulleted list is easier to scan. If they immediately see something interesting, they are more likely to read your page.
