Whatever your specialization, you can enhance your
authority as an expert via online sharing. These
methods have worked for me.
1. Write a blog. Post at least one thoughtful article each
week on a subject helpful to your readers. You may
soon be invited (or you can offer) to contribute to other
blogs, thereby expanding your audience.
2. Offer a newsletter. Compile a monthly or weekly email
with tips, article links, event announcements and
exclusive offers, and send it to your mailing list.
3. Write guest columns. When you contribute to online
news hubs, you increase your audience, attracting more
eyeballs to your blog or newsletter.
4. Tweet. Often. Post something that interests you on
Twitter several times a day. Others will catch on.
Whatever online methods you choose, be sure to refresh
your content regularly.
