I suggest that you focus on the sub-niche that you will be targeting.
Everything else will flow from there.
If you think about it, by picking the right sub-niche, coming up with topics to write about and coming up with the proper structure of your content as well as the structure of your website actually take care of themselves.
How?
Reverse engineering!
As long as you nail the sub-niche identification stage correctly, you can reverse-engineer everything else.
Let me spell it out for you.
For example, if you have decided to blog about certain types of lawsuits involving a certain range of situations involving a certain range of people, you can then find a website that already talks about that topic.
Enter their domain names into paid SEO tools like SEMrush or Ahrefs, and you will get lots of organic keywords that these sites already rank for.
You then cross-reference these keywords' difficulty with their monthly search volume as well as their search intent.
I can't emphasize the search intent part enough!
This is where the rubber meets the road.
If you are able to deliver on the intent of your target keywords, you will rank better than your competitors.
It's only a matter of time.
The key is to reverse-engineer your competitors, come up with better content, make sure that your content is up to date, more comprehensive, and actually delivers the experience searchers are looking for when they type in your target keyword into Google.
If you can do this and you interlink your content correctly, your new site will be a success.
It's just a matter of time.
Also, don't just publish 10, 20, or 30 posts and call it a day.
This is another common mistake I see newbie bloggers commit again and again.
How much content do you need to post?
Well, I don't mean to depress you, but you should post at least 100–150 pieces of content.
I'm talking about high-quality content that is long enough.
I'm not talking about bits and pieces of 250 posts or brainfarts that are 500 words in length.
These must be substantive.
They also must be complete.
They have pictures as well as videos if you can find a good one.
So this takes quite a bit of time, and you can save some time by either outsourcing or training yourself to become a dictablogger.
In other words, instead of writing things out by hand, dictate to a microphone so you can maximize your volume.
Most people are able to manage 2000 words per day when they write things out by hand.
But if they dictate, such as myself, I can produce 25,000 words or more per day.
The numbers speak for themselves.
