Tanya, if I were to come and visit you, and I asked about your niche, what would be the very first thing you would say to me?
OK, now, take that thought, and sit down at your computer and write just like you are talking to me. Tell me about your niche. Just like you are having a conversation. It doesn't have to be very formal. Write it just like you are talking about it.
Hope this helps.
All the best,
Wendi :)

Tanya. Just take a moment and think of your subject. What would you like your audience to learn. Remember you have a solution to their problem. Explain it in a way that convinces them that you have the right solution to their problem. Start with something that will get their attention and make them want to stay for the solution.

Perhaps if you put yourself in your readers position. If someone clicked on your site....what would they want to learn about or read about. Comments below are excellent avenues as well.

When I don't know what to write about I surf 3 sources
Google
YouTube
Client reviews on product pages as Amazon

I read about 20 blogs/videos take from every blog or video 2 key sentences, after that I have 40 sentences to work out for a post of my own

I hope this will help you further

Gather as much information you can about the topic you are about to write. Put it into some sort of outline. Put up a picture before writing any words.

Start writing your intro to your content and make sure that you include your keywords phrase in the first paragraph. After your intro to the content, put in your headline for the next paragraphs to follow and write. Repeat as necessary and be sure to include photos or pictures related to your topic.

Here is one of my posts from my website so that you can get the idea of what I am referring to.

Everyone has a style of their own depending on what the site is about.

Hope it helps a little and good luck!
