Google+ blogging isn't for every blogger. If you really need custom design, traditional archives, widgets and other nonblog functionality or advertising, you're better off with a regular blog platform.
But for everyone else, Google+ is the by far the best place to blog.
How I blog on Google+
Here's my advice for how to blog on Google+. First, create a "headline" by bolding the first sentence. Type an asterisk on either side of the headline to bold it.
Google+ offers a place to add a link, which auto-generates a thumbnail picture and "blurb" at the bottom of your post. This is fine for the personal social sharing of links. But when you're blogging, never use this option. The thumbnail is too small to attract the eye, and the blurb is an extraneous element that competes for attention with your headline and post.
I believe that accepting the auto-generated thumbnail and blurb is the single biggest mistake that some Google+ bloggers make.
Upload a full-size picture. Don't accept the auto-generated thumbnail.
Alternatively, add a video by simply pasting the YouTube or Vimeo URL anywhere in the body of the post. Google+ will automatically add the video. Once the video appears at the bottom of the post, you can delete the URL.
Once your picture or video is in place, paste in any links you want to add at the bottom of the post. Google+ will convert them into live links for readers.
If you refer to an organization, publication or person, try plus-mentioning them. By typing a plus sign and then the name, you'll get a drop-down menu of possibilities. Choose the right one, and that plus-mention will point your readers to the party's Google+ page with an auto-generated link, and those mentioned will probably be notified the post. Never assume that organizations or people aren't on Google+. I've found that 95% of the people or organizations I refer to have Google+ profiles or pages.
One of the great things about Google+ is that you can add email addresses to the addressing, and your blog post will be delivered as an email. So if you mention a company, or want to bring your post to the attention of people via email, just add their email address.
Give credit at the bottom of posts. I credit the source of the picture or video, credit the source of the story idea and also use the Google+ search feature to find out who was the first person to mention the news on Google+ and credit them for that as well.
