What is SEO?
Search engine optimization (SEO) is the practice of getting targeted traffic to a website from a search engine's organic rankings. Since organic search is one of the ways through which people discover content online, higher rankings can translate to higher organic traffic to a website.
SEO includes both technical and content practices aimed to align with the best search engine algorithm needs. Common tasks associated with SEO include creating high-quality content, optimizing content around specific keywords, and building backlinks.
In other words:
SEO is all about improving a site's rankings in the organic (non-paid) section of the search results.
The main benefit of ranking for a specific keyword is that you can get "free" traffic to your site, month after month.

How Search Engines Work
Now it's time to learn how search engines like Google actually work.
How did you land on this result? chances are you keyed in the search 'What is SEO?' or something along those lines, and the search engines did the rest.
When you search for something in Google (or any other search engine), an algorithm works in real-time to bring you what that search engine considers the "best" result.
Specifically, Google scans its index of "hundreds of billions" of pages in order to find a set of result that will best answer your search.
How does Google determine the "best" result
Google remains coy about its ranking metrics but based on expert research and a few hints from the search engines; crawlers or bots are used to gather information available on the internet. By using website navigation, read internal and external links, the bots understand the context of a page, and the search engines offer the pages with better visibility as best results.
Even though google doesn't make the inner workings of its algorithm public, based on filed patents and statements from Google, we know that websites and web pages are ranked based on:
Relevancy
If you search for "chocolate chip cookie recipes", you don't want to see web pages about truck tires.
Search relevance refers to the measure of the accuracy of the relationship between the search query and the intended search result. domains with accurate, rapid, and relevant results get prominence from the search engines and hence rank top.
That’s why Google looks first and foremost for pages that are closely related to your keyword.
However, Google doesn’t simply rank “the most relevant pages at the top”. That’s because there are thousands (or even millions) of relevant pages for every search term.
For example, the keyword “cookie recipes” brings up 349 million results in Google:
Importance of Search Relevance
Imagine landing on a site and it provides a clear mismatch between your expectations and the search result. It implies such a site is both unprofessional and unreliable.
Statistica indicates a whopping 68% of people are unwilling to return to a site with poor search experience. In this regard, aim to build personalized, highly relevant, and target-driven content that meets search intent.
So to put the results in an order that bubbles the best to the top, they rely on three other elements of their algorithm:
Authority
Authority is just like it sounds: it’s Google’s way of determining if the content is accurate and trustworthy.
Authority refers to the overall influence and reputation a domain bears in a specific niche. Google considers the authoritativeness of a website based on its wider acceptance in the target niche.
The question is: how does Google know if a page is authoritative?
They look at the number of other pages that link to that page:
(Links from other pages are known as “backlinks”.)
In general, the more links a page has, the higher it will rank:
(In fact, Google’s ability to measure authority via links is what separates it from search engines, like Yahoo, that came before it.)
Importance of Authority
A website derives its authority from its ability to offer value. In short, other niche players know your background, accept your unique views, and look up to you as a thought leader.
This way, other domains easily connect to your domain through backlinks. Google interprets this as a vote of confidence and is likely to assign higher rankings.
Usefulness
Content can be relevant and authoritative. But if it’s not useful, Google won’t want to position that content at the top of the search results.
Time and again, Google has been unequivocal in calling for ‘quality over quantity’ for best search results. Usefulness refers to providing engaging, relevant, and valuable information to website visitors.
In fact, Google has publicly said that there’s a distinction between “higher quality content” and “useful” content.
For example, let’s say that you search for “Paleo Diet”.
The first result you click on (“Result A”) is written by the world’s foremost expert on Paleo. And because the page has so much quality content on it, lots of people have linked to it.
However, the content is completely unorganized. And it’s full of jargon that most people don’t understand.
Contrast that with another result (“Result B”).
It’s written by someone relatively new to the Paleo Diet. And their website doesn’t have nearly as many links pointing to it.
However, their content is organized into distinct sections. And it’s written in a way that anyone can understand:
Well, that page is going to rank highly on the “usefulness scale”. Even though Result B doesn’t have as much trust or authority as Result A, it will still perform well in Google.
(In fact, it may even rank HIGHER than Result A.)
Google measures usefulness largely based on “User Experience Signals”.
In other words: how users interact with the search results. If Google sees that people really like a particular search result, it will get a significant ranking boost:

Importance of Usefulness
Most businesses scramble for top rankings on SERP; through paid or organic traffic. High rankings attract interest and get more visibility, resulting in high conversion rates and brand authority.
Usefulness underlines the value of organic traffic in fully satisfying search intent. Organic traffic in itself shouldn’t be the end goal.
What do you want the site visitors to do? Buy a product, follow a recipe, or seek your services? Meeting these goals requires you to offer usefulness aligned with the user intent.
