I have my Google blogger Account and I want to post many post on a single page how its possible at that time I am not able to post. Its only post one post on a single page.
First thing, why do you want all your posts on single page? Its better to host blog post snippets on home page and linking them to the whole post on another page. This is a good SEO practice and may help in ranking of our every blog post.
If you will post multiple post on one page than keyword density will be increase and also number of scroll will increase. that is not good from seo point so you should not think about it.
I want to create a SMS blog so density doesn't matter and I want different page for different theme sms.
I guess if you want that kind of set up, you may want to categorize posts so it will appear as one page. You can select a magazine type of template which has many pre-created pages. Just edit them on HTML layout page of your template.
