What is the core of SEO?

Three Core Components of a Strong SEO Strategy

To optimize a site, you need to improve ranking factors in three areas — technical website setup, content, and links.

technical SEO: How well your content can be crawled and indexed. content: Having the most relevant and best answers to a prospect's question. on-site SEO: The optimization of your content and HTML. off-site SEO: Building authority to ensure Google stacks the deck in your favor.
