Quality content is the key to getting your website noticed.
Be sure to make certain that whatever you decide to focus there is an interest in it. There might not be that much interest in something like “How many states use the letter ‘A’ in their name”. Not sure how many people that would attract if all your site does is talk about the placement of the letter ‘A’ in state names.
You can do keyword searches to find out how much interest is in various things you can write about. You goal is to get listed on the search engines and draw attention from your social media sites. Do to that you must have original quality content. It is really not as difficult as it sounds.
There are many sites that can help you with that, but only a handful that will give you quality advice for FREE. I recommend THIS LINK if you want to find out more about keywords and quality content ideas.
