How Does SEO Work?
Paid and "organic" search results appear on the SERPs (Search Engine Results Page), with organic results not contributing to Google's income. Google instead provides organic results based on its evaluation of a site's relevancy and quality. Google will display different items on the SERP depending on the type of search queries, such as maps, photographs, or videos.
The number of adverts displayed on a SERP is determined by what users have looked for. If you search for "iPhone," for example, you'll likely find that many of the top results are advertisements. In reality, the first organic result will most likely require scrolling down the page.
The purpose of SEO is to improve your organic search results ranking. AdWords (Google Ads), shopping, and local results are all optimised in different ways.
While it may appear that there are too many competing components on SERPs to push organic listings down, SEO may still be a highly powerful and profitable activity. Organic search results are a very small piece of a very huge pie, given that Google handles billions of search requests per day. While some initial and ongoing expenditure is required to achieve and maintain organic rankings, every click that leads to your website is entirely free.
