SEO is important when you have a business. But posts that use SEO are not so important for the people who consume them.
Just because there are SEO rules now don’t mean they won’t change in the future.
Don't just please the machine, focus on people and connect with them. One way to achieve that is to host events for everyone or to give real value. Then you can ensure you will be successful even if your page is not the most SEO friendly.
