Step-by-step explanation:
The best tool in marketing is Search Engine Optimization (SEO).
SEO involves optimizing your website and its content so that it appears at the top of search engine results when someone searches for keywords related to your business. This helps drive organic traffic to your site and increase visibility, which can lead to more potential customers finding and interacting with your business. SEO encompasses several factors, such as keywords, content, meta descriptions, backlinks, and more, and involves both on-page and off-page optimization.
The other options, such as menus, posts, and categories, are important for a well-organized and user-friendly website, but are not directly related to marketing and driving traffic to a site.
