If I’m getting hundreds of views and downloads of my articles, why am I not getting lots of subscribers to me newsletter?
Easy answer = You have not hit scale yet. :-)
Recommend writing at least 200+ articles that will attract tens or hundreds of thousands of views over time (meaning using articles to grow a list is not an overnight method and builds like a snowball rather than a race car).
Also, many authors only put anchored text links (instead of a full http:// URL) and they lose active links as the article syndicates.
Lastly, be sure to offer an incentive…such as a special free report when they join your free email newsletter. Benefit oriented copy always works better than me me me me my my my newsletter. You get the point. :-)
