The length of time it takes for SEO to start generating traffic can vary depending on a number of factors, including the competitiveness of your industry, the quality and relevance of your website's content, and the effectiveness of your SEO strategy.
In general, it can take several months for the effects of SEO to become noticeable. This is because search engines like Google use complex algorithms to rank websites, and it takes time for them to discover and index new websites and pages. It can also take time for your website to climb the search engine rankings and start to appear on the first page of search results for relevant keywords.
That being said, it is possible to start seeing some results from SEO in a shorter period of time, especially if you have a well-designed and optimized website and are targeting low-competition keywords. However, it is important to be patient and understand that SEO is a long-term strategy that requires ongoing effort and optimization to be effective.
