But it's hard to imagine 75 year olds worrying about SEO. The people described in these stories seem to be just putting up websites to occupy time and have something to do. The little known fact about SEO is that if you have tons of great content, it doesn't matter what SEO you do, you'll get search traffic.
So success by accident. Another little known fact, google's rankings aren't perfect.
yeah but they are using blogs so virtually all the on page SEO is done automatically (title tag, H1 tag, URL etc) if they are creating good content they'll get links - hey presto
