There are some specific features anyway.
1. Should I keep this link to default blog page as /category/news/ or should I change it to /news/? If category should be as is – should I change the name of the word “category” to make search engines more aware of the content specifics?
2. There is a problem with open and closed lessons. The free lessons should be included in the sitemap, but the links to the paid lessons in the sitemap are not suitable for SEO. The manual addition of free lessons to the sitemap is complicated, and I am still looking at how to resolve the problem with AllinoneSEO plugin.
