Keyword Research is finding the words people type into search engines. "Good Enough" SEO is a "findable" approach that isn't overly technical or perfect.
Don't obsess over "ranking #1" for competitive keywords. Focus on "Good Enough" SEO: answer the specific questions your customers are already asking. By building content that answers their "how-to" problems, you become the helpful expert—and search engines will naturally reward you for it.
