What's the single highest-priority item on this checklist?

Directly answering "will this actually move the needle for a business like mine, and what's the real cost" somewhere prominent — it's the actual starting point for most searches in this category.

How often should this checklist be revisited?

Quarterly at minimum — content goes stale, technical issues creep in, and competitors add new pages, so a one-time pass isn't enough.
