With shortcodes it’s easy. The content counts for SEO, even if what ever tool you’re uisng to “rank” your pages in your admin area doesn’t see it.
For 1-page themes, that’s a lot more difficult. You’d need to ask each themes authro how it works, as it’s possible for each one to do it in a different way. Some will be SEO-friendly, and some won’t be.
thanks for feedback.. I have Yoast installed but shortcode pages don’t seem to have a good “score” on Yoast (at the bottom of the page). I want to make sure that my pages still rang high.
The score in that SEO plugin is a vague idea of how well the pages text content holds up. There’s 1,000’s more factors that go into good SEO then just that, so don’t think that getting a green icon for any page will mean that it will rank higher than any other page. Google doesn’t see those results, and wouldn’t care about them even if they could.
