Every time we search for information online, a search engine decides what results to show us and in what order. These results appear on a page called the Search Engine Results Page or SERP.
To understand why certain websites rank higher than others, it is important to know how the SERP layout works and how search engines process information.
In this article, you will learn what SERP is, how a SERP is structured, and how search engines work step by step.
What Is SERP?
Whenever we search for something on Google or any other search engine, we see a list of results. This page is called the Search Engine Results Page, commonly known as SERP.
For example, when you search for “best digital marketing course,” the page showing all results is the SERP.
The main goal of a SERP is to show the most relevant and helpful results based on the user’s search intent.
SERP Layout: What Does SERP Usually Contain
A SERP layout refers to how search results are arranged and displayed on a search engine after a user enters a query. The layout can change based on the search intent, device, and keyword type.
A SERP layout usually contains top 0 to 4 ads, followed by other result types and Bottom 0-3 Ads. The other results include the following:
- Organic Results – These are unpaid search results that appear because of good SEO.
- Paid Ads – These appear at the top or bottom of SERP and are marked as “Ad.”
- Featured Snippet – A short answer shown at the top of the page, also called position zero.
- People Also Ask – A section showing related questions users commonly search for.
- Images and Videos – Sometimes SERP includes image results or video previews.
- Local Pack – For local searches, Google shows nearby businesses with maps and reviews.
- News or Top Stories carousel – Appears mainly for trending topics, current events, and breaking news.
- Discussions and forums – Shows real conversations from online communities.
- Recipes – This feature appears when users search for food-related queries.
- Popular products – Shows product listings directly on SERP.
- Related Searches / People Also Search For – Appears at the bottom or within the results page helping content creators understand what users are also interested in and create better content around those topics
How Search Engines Work
Search engines follow a simple process to find and show results. This process happens in four main steps.
Crawling – Search engines like Google collect data from all the websites both new and existing with the help of software programs called Bots / Spiders / Crawlers. Hence this process is known as crawling or spidering.
Indexing – After crawling, search engines store the collected information in a huge database called an index. Pages that are not indexed will not appear in search results. This content is segregated into categories and subcategories for easy access.
Calculating relevancy – If a user searches for a keyword then the search engine gathers all the info that is relevant to the user search query.
Ranking – Each page will be given a score according to its relevancy with the user search query.This is known as Page rank. PageRank is an algorithm used by Google Search to rank web pages in their search engine results.
When a user searches for something, the search engine checks its index and ranks pages based on many factors such as:
- Age of website
- Content quality
- Keyword relevance
- Website speed
- Mobile friendliness
- Backlinks and authority etc.,
The most relevant and useful pages are shown at the top of the SERP.

Understanding SERP and search engine working helps you:
- Improve website visibility

Understanding how SERP works, its layout, and how search engines find and rank websites is very important for website owners, bloggers, and digital marketers to create better content and improve their visibility in search results.
