The short answer is that SEO is very effective, not only to drive traffic but also leads and sales. Do not you worry. The long answer includes research and data, not just empty statements.

Estimates are that U.S. companies spend more than $ 80 billion on SEO services. This figure is significantly higher than in 2018, when it was estimated that companies would spend $ 72 billion on search engine optimization.
