Blogging can be a useful tool to present opinions, share information, or attract people who want to read about something you produce -- books, crafts, consulting advice, etc. Blogs can simply be fun, too.
Since late 2011, I've blogged about writing, family history, book marketing, and whatever suits my fancy. I decided many years ago to write a quality product and not worry about whether my articles are read 500 or 2,000 times per month. If you want to acquire paid advertising for a blog, that matters. Otherwise, don't worry about it.
WordPress has more templates and is said to be better equipped for commerce. I had trouble figuring out how to set up a blog there. Since 30% of the world’s bloggers use it, the problem was clearly mine. (I've since had help in transferring my webside to WordPress, and could blog there. However, since this blog is well-established, I simply reference it on my website.)
A second choice will probably be whether to “self-host,” which means buying a domain name to place with Blogger or WordPress (or another site). In so doing, you are essentially creating a website (and probably paying to host it) and using the site as a blog.
People who advocate self-hosting point out that you will own your content and it will be harder to steal it. I would suggest these two reasons may not be crucial. You own your writing unless you give the copyright to someone else, and anyone can copy and paste what you write, no matter where you post a blog.
The advantage to self-hosting (a.k.a. buying a domain and paying a website host) could be better capability to add videos, sell products, and add plugins. There are likely more advantages, and you can read about them at different hosting sites. I plan to keep writing books rather than learn more about blogging.
I'm happy with my free site at Blogger, which Google hosts. The hardest thing for me is remembering to write a post three times a month. You'll see I started strong, waned, and am now more consistent.
Content matters most. Wherever you place your blog, I suggest an index, organized by broad topics. You can get to the index to Irish Roots Author by clicking that link at the top left of this page. Have a look.
