How do you build an internal-linking strategy for a large website?

For each important page, determine:

• which pages should link to it;
• what contextual relationship those links represent;
• what anchor text is natural and descriptive;
• whether the link is crawlable;
• whether the destination is canonical.

Then audit inbound internal-link counts and source quality.

The goal is not maximizing links. It is creating a useful, crawlable information graph.
