So which of the strategies is best for long-term online marketing?

That depends on what your goals are. If you’re interested in the highest possible return on what you invest, email marketing is probably your best bet, but if you want a well-rounded strategy with many benefits and virtually unlimited growth, content marketing is better.If you want the absolute best results, no matter what your goals are, you should be using these four strategies in tandem with one another. Individually, they’re each a powerful way to build your reputation and attract more traffic to your site, but together, they’re far bigger than just the sum of their parts.
