Google measures the website by updating various algorithms. In Past years, Google used to update minor algorithms to meet certain parameters. Now, Google makes thousands of major algorithm updates every year like a panda, penguin, pigeon, hummingbird, Fred, Page layout, mobile update, Rank brain, etc.
Google Algorithm is a bunch of deciding rules that the web indexes utilize to decide the meaning of the site. Each web search tool has its own standard. From time to time, this Google algorithm calculation attempts to give better query items and significant answers for users on the web.
Every time, A webpages published, then this Google-bot comes across to crawl and then index and lastly it ranks those pages that are relevant to the intent. So whenever a user queries any specific keywords, then Google makes sure to give the best and most relevant answer.
In this matter, the Google algorithm works as the ranking factor for every website, that is the reason, Google rolls out new updates every year. Google algorithm updates are unnoticeable. Yet, sometimes, Google rolls-out is so superior that it discord the way we do SEO every time.
How Does Google Algorithm Work?
We will go through some points, which were officially listed by Google itself and they are:-
1. Meaning Of The Query
To give relevant results for users, Google must know the user intent. They must understand the natural meanings of those keywords/Query. By using a particular query, what user wants- either review, descriptions, graphs, or finding specific websites? Google must understand this user intent.
And sometimes, it’s necessary to understand to give freshness to content. For example, when we Search for trending products in the market then, of course, we want recent product details with fresh content.
2. The Relevance Of Pages
Secondly, the search engines have to find the relevant pages from those websites, that users query with keywords, which plays a big role here and it does by regular crawling and indexing of all websites and investigating and finalizing the content for a relevant query.
3. Quality Of Content
We all know that the “Content is a King” for a reason. Generally, Google has millions of pages for each keyword but has to filter the one that gives content best and demonstrates well, and matches user intent.
4. Usability of Pages
Google has continuously focused on the ranking factor in technical aspects. They make sure the web pages have a simple structure, are mobile-friendliness, are fast and responsive, and security of websites having HTTP, etc. All this in just a second!!

- Core Web Vitals:
As discussed above Core Web Vitals are metrics focusing on site speed, interactivity, and visual stability of web pages. They are:
- Largest Contentful Paint (LCP): LCP metric estimates the loading performance of the web pages. To give a good user experience, LCP should be in the range of 2.5 seconds, when pages start loading.
- First Input Delay (FID): FID metric estimates the interactivity of users with webpages. This ought to be under 100 milliseconds.
- Cumulative Layout Shift (CLS): CLS metric estimates the steadiness of points of arrival. the page ought to keep a CLS of under 0.1.
