Marketers cannot predict, nor guarantee a certain outcome in terms of what actions the website visitors would take on the website. The website visitors will retain their free will, so the actions they will or won’t take will also depend on the website itself and the competitiveness of the business. Marketers specialize in generating high-quality traffic and if that produces results, marketers can also further improve those results. While I do guarantee top-quality work, which results in targeted traffic for the best-possible outcome, please note that marketing is an investment. Investing comes with the risk of losing money.
