Ans. Search Engine Optimization is the practice of improving the quantity and quality of incoming traffic to your website or domain organically via search engine results. SEO works to increase the visibility of the business. The audience trusts organic results more than paid results.
If your website is listed for the relevant and correct keywords, it brings quality traffic to your website. In addition to this, try explaining what SEO is in your own words rather than going for definitions. Companies want to know what your understanding exactly is.
