How to write first blog (visit here)
Go to offical site of Blogger (Blogger.com). you need Gmail account for sign in This is the very first step for you journey on starting a blogger blog.

Click on Sign In in the top right corner and then select one of your gmail accounts to sign in.
Note: If you have only one gmail account logged in to your system, you will automatically be led to the dashboard corresponding to the Gmail account.
The next step is confirming your profile, that is, how your viewers will see you.

You can either choose your Google+ profile or if you wish to stay anonymous, you may select the blogger profile. To choose a blogger profile, click on the link below, the one that says ‘Switch to a limited blogger profile’.

If you are choosing a Google+ profile then skip the next two-three lines.
Once you selected the blogger profile, you will be asked for a pseudo-name or the display name as they say.

Once you are done, you will be taken to your dashboard.

Step 2: Getting you blog ready
Once on dashboard, go and click on the ‘New Blog’ dropdown in the top left corner.

Once you clicked on it, you will see an option named ‘new blog’.

Click that and a pop-up will welcome you.

Enter the title of your blog and a ‘.blogspot.com’ subdomain address that you wish to use for your blog. Don’t worry you can add a custom domain later and can even purchase one from Google domains.
Choose the theme and click Create Blog. Don’t worry about the theme as you can change it too. You can also use a custom theme later, that is either made by you or downloaded from the internet. Moreover lots of themes and customization will be made available to you once the blog is created.
Once you proceed, a pop-up will ask you if you wish to buy a custom domain and use it.

Select ‘No thanks’ if you wish to continue with a subdomain or look up for one if you want a custom domain.
Once you completed it, you will be welcomed to your blogger dashboard.

Step 3: Setting up your blog
On your dashboard, click on ‘create a new post’ to make your first blog post. For SEO, select settings from the menu on your left.

Add description to your blog.

Select Search preferences from the menu on left.

Add description in the Meta tags there.

Deleting the Blog
However this is not in the scope of this answer but I guess that anyone making a blog may need to delete it too. As I needed to delete my first five blogs.
So, to delete you blog, Go to ‘other’, its just below search preferences.
From there select ‘delete blog’ and your blog is no more.

However it will not be permanently deleted and you can restore it within thirty days of deleting it.
Friends I think niches should be lovable make your article best try to give them unique.
