Long ago, I wrote a simple article, Adding A Blogger Blog To A Website. That's become one of the most consistently popular posts, in this blog. Most blog owners have multiple interests, and like to organise their different interests, by subject - and have a different blog, for each subject.
Some people like to have a blog, and a website - and host both the blog and website in one Blogger blog, under one URL. For a small blog / website combination, that's an easy way to start out - and a good alternative, to having multiple blogs / websites.
It's easy to create a Blogger blog, and have the blog host multiple virtual blogs and / or websites.
The simplest "blog" uses a static home page, and the posts accessed from Pages, as "Blog".
A static home page - and all posts accessed as "Blog".
First, redirect the Home page to a static page.
Then add a simple dynamic "Blog" page, using "Configure Page List" - if you want all of the posts visible from the "Blog" tab.
But, there are more possibilities.
Organised right, you can do without an archive section.
Done carefully enough, you can maybe display an entire blog without archive pages.
Have enough sections - and consistently use Jump Break on the posts - may let you fit a dozen or so posts onto one index page.
Some people organise blog content, using static pages.
The most obvious solutions for this need - to some people - is to setup static pages, one page / subject. But sometimes, interests / subjects overlap - and material that's published on one static page (as in one blog or website) might be relevant to another page (or blog / website).
I recommend basing the blog on dynamic content - and dynamic accessories.
The easiest way to make all of the content accessible is to add various dynamic indexing and search accessories. But some static structural accessories are useful, too.
Then, add a Pages gadget, if not already added. You can have a linkbar / tab index - or possibly a linklist, positioned anywhere convenient. Or both.
Start by labeling your posts.
First, add labels, to the posts. You can use either the posts index, or post editor, to add labels. You use the former, to add one label to many posts - and the latter, to add many labels to one post.
With the posts well labeled, decide how you want to display the pages.
Dynamic content lets you display one post, in multiple pages.
Using this blog as an example, this post could be useful in my "Labels", "Magic", and "Redirecting" sections of this blog, to start. Look above, at the toolbar. Do you see the "Magic" button?
Hover the pointer cursor over "Magic" - and see what's there.
From: /Magic To: /search/label/Blogger%20Magic
There's my "magic" blog, within this blog.
Just as easily, I could have "Labels" and "Redirecting".
From: /Labels To: /search/label/Labels
From: /Redirecting To: /search/label/Redirecting
You can separate the "Home" page from the "Blog" page.
Some people want to keep the blog and home page separate. They have 2 labels, "Blog" and "Home". All that they do is publish various posts, to either label - and setup 2 redirects.
From: /Blog To: /search/label/Blog
From: / To: /search/label/Home
And there's a blog
within a blog.
Making things simpler, if you want "Blog" to index all posts (as in an actual "blog"), you don't need to label the posts. Apparently, "... /search/label/ " retrieves everything, instead of nothing.
From: /Blog To: /search/label/
There are several possibilities for "Home" page content, too.
As an alternate to redirecting the home page to a label search, you can always redirect the Home page to a single post - if that's your preference.
From: / To: /2014/07/blogger-magic-blog-within-blog.html
And that is a very basic blog, within your blog.
And you can still use static pages, for truly static content.
And one final detail - add one or more actual static pages. For non changing content, that you don't want ending up in a search engine hit page, add a simple static page.
You may have to add the Pages gadget, using "Add a Gadget".
Most blog owners will use the Pages gadget, to index their dynamic and static pages (such as "posts" and "pages"). If the Pages gadget is not already present in the blog, you may use the dashboard Layout page and "Add a Gadget", to add the gadget. Then, use "Configure Page List" to add the pages created.
