Unstructured
A presence exists. It is not being directed. Most of what you have built is invisible to the people who would act on it.
You may be good at what you do and almost nobody can verify it. Your name returns little, your work lives on platforms you do not control, and opportunity arrives through people who already know you.
Assuming the problem is volume. Publishing more into an undirected presence produces more undirected presence.
Own something. A domain with your name on it, one page that says what you do, and one channel you publish to on a schedule you can hold on a bad week.
