What Marketing Services for Publishers Actually Work Best Today?

[jacobparkin]

I’ve been trying to understand how marketing services for publishers really perform in today’s competitive book industry. With so many options like social media ads, email campaigns, SEO, and influencer outreach, it’s hard to know what actually brings consistent results for book marketing. In your experience, which strategies or services have worked best for reaching readers effectively? Do you think traditional methods still matter, or has digital marketing completely changed how publishers promote books now?
