It really depends on the search intent behind the query and what you’re trying to rank for! Typically for matters of SEO, a long tail keyword or query is usually a broad term (running sneakers) + words that refine the search intent (white running sneakers size 14). So the sentence “tariffs won’t bring in enough income to get rid of the income tax” is super specific but probably too long to actually optimize for. Instead “will tariffs lower income tax” or “can tariffs lower income tax” would better capture the search intent and have meaningful traffic behind it. Also, a table of contents is not necessary at all, for SEO. It just depends on the kind of blog, really. If a blog is meant to be read in order, like this one, it doesn’t really need a table of contents because jumping around the article wouldn’t serve the user very well. However for a recipe blog, for instance, a table of contents is helpful because it allows the user to jump right to the recipe or other important sections. Hope that helps!
