The following example is not a one size fits all. Every article is unique and will require its own structure to satisfy the content. However, this example can be used as a visual guide to help you brainstorm the right structures to use for your evergreen articles.
If you successfully define or explain one term or answer one question, the reader will likely have follow up questions. Keep the reader on the page by addressing their follow up questions in H3s. The example below provides a structure that can help you capture featured snippets and have your answers appear in the People Also Ask box on Google.
Table of Contents: A ToC tends to add significant SEO value to longer articles that focus on dissecting a complex topic. Depending on how they are structured (i.e. a list of names or places) ToCs can sometimes be snipped out and used as featured snippets or as answers in the People Also Ask box on Google SERP. Since ToCs make it easier for readers to find the information they are looking for quickly, this practice is good for SEO and may help to raise the ranking positions of your evergreen articles.
Sourcing and Linking : While it's frequently suggested that you don't link to a competitor's website, sometimes it's unavoidable. Google is constantly updating its algorithm to emphasize YMYL content and quality backlinks. To avoid the problem of losing through-traffic to your sources, consider burying sources in a sources section beneath your related content. If you link to your sources throughout the article, consider numbering them using superscript. People are less likely to click on superscript text than they are on good anchor text. So, make sure to have a good anchor text when interlinking to your articles. Just remember to never link downward in quality.
Word Count and Ranking Position: Generally speaking, if you write a longer evergreen article that uses keywords in a natural you, way will have an easier time ranking high on SERP. There is no set in stone or one size fits all rule for word length, but thoroughly explaining an evergreen topic often takes anywhere from 1000 to 2,500 words.
