A financial-services blog is an effective way to attract readers who can then be converted into clients, says Jason Wenk of Retirement Wealth Advisors. He advises prospective bloggers to first survey clients to determine their most pressing concerns, then use that information to craft engaging twice-weekly posts. The content should avoid sales pitches, but include a way for prospects to request further information, Wenk says. He also recommends seeking the services of a compliance officer and a lawyer.
