I think you should brainstorm about it on a piece of paper for a few minutes. Then jot down the first things that come to your mind. If that doesn't help. I would suggest you using Jaaxy keyword search. You get 30 free searches check out the image attached to see ideas that come up when I search "how to start a business online".

If you have a Gmail account, use Google alerts or Google trends. Both should give you a lot of information.

I think the most logical thing to do is to do some good reading on the Internet. Do some searching and find some pertinent information on your topic. Read, read, read to educate yourself more on your topic, and then you'll find it overflowing into your writing. It's easiest to write about something you've done a good bit of reading on. It's OK to use some of the same material as long as you're putting it into your own words and attributing it to the sources when you're giving detailed information, certain statistics, etc.

Thank VitaliyG, but even if I leave the page blank my comment is not posted, it keep asking to enter a real url.

You can leave that blank Ayawa, I normally don't leave my URL.

You might have de-activated comments or there's a theme issue preventing that from showing. You need to go into your posts, click quick edit and make sure there is a checkmark on the "show comments".

You can build one anytime, but as some members said here, it's better to make it while you're going through each lesson. Lesson 4 in the starter guide will lead you to make one.

Best to work your way systematically through the process, AAmouzou. There's no harm in creating a website though, just try to make sure you choose a good domain name for your niche!

You don't have to wait. Go through each lesson and when you get to the lesson telling you to build your website, start building. Build as you learn.
