Search engine marketing is a way of getting people to your website by using a search engine, like Google. It involves making sure your website appears at the top of search results, so more people can find it and visit it. To do this, you need to use keywords that people are likely to search for, so your site will be at the top of the list. You can also pay for ads to be shown at the top of the search results, so even more people will see your website.
