Why It Matters
What SEO Should Help You Do
Search visibility is useful when it connects someone with a page that answers their question. A service page should help a potential client decide whether to get in touch. A product page should help a shopper choose what to buy. A resource should help a member, student or researcher find what they need.
SEO work should make those paths clearer. That includes helping search engines reach and understand the site. It also includes deciding which pages need to exist, what they should explain, how they connect, and what happens after someone arrives. Google's own guidance emphasizes helpful, reliable content created for people rather than content made mainly to influence rankings.
