There are two types of search results on the search engine; organic and paid search. When you have a strong SEO strategy and strictly adhere to search engine algorithms, your site earns a spot on search engines through organic search. On the other hand, paid searches are when you pay a set amount for each click on your ad. Such searches quickly rise to the top of search results. In organic search, you may need to work on the site for six to twelve months to gain better visibility. Paid searches are the primary source of revenue for search engines.
