What Is SEO, and How It Works

SEO is the process of optimizing your website according to search engines to improve its ranking so that you can attract more visitors. Google has a complex algorithm that depends on many factors through which it determines which web page has the best solution to the user’s query to show them.

Google focuses on factors that determine the quality and ranking of your website. By understanding these factors, you can enhance your website’s SEO performance and gain a higher ranking in search engines.

Another essential factor may include gaining high-quality backlinks from other websites that can help build your website’s authority. Moreover, optimizing your web page, i.e., its meta tags, title, meta descriptions, URL, and keywords, is also essential for better crawling and indexing on search engines.

How Search Engines Work?

Search engines are software systems that users use to find answers to their queries. The search engine algorithms find the content that meets the user’s intent and query and rank those pages and the keywords higher in the search engines if they meet their ranking criteria.

So, three important factors search engines use to suggest pages for ranking are crawling, indexing, and ranking. Let’s learn about these factors in detail below.

1- Crawling:

Once your content is published, the spiders and bots of search engines come to your new web page to review it and find out what’s new and updated. Search engines crawl new web pages through the internal links from existing pages, where they easily find pages you recently uploaded. Through following these links, the crawler comes to your site’s new blog post and analyzes what your content is about.

2- Indexing:

After crawling search engines, decide whether the information you have added to your web page is relevant and useful to its users. Then, your page will be indexed and appear in the search engines. Search engines will not index your web page if they find it spammy, irrelevant, or duplicate. To check that your web pages appear in Google, you have to follow the guidelines:

1- Go to your website and open the page you want to check for indexing.

2—On the top search bar, you will find the URL of the content; copy it.

3- Now, go to the Google Search Bar and paste the link.

4- It will appear to you in the index search.

Note: Sometimes your web page is not found in search engines, so in this case, you need to wait to appear in search engines or reindex it, but remember, don’t try again and again for reindexing.

3- Ranking:

If you write helpful, relevant, and high-quality content that matches Google ranking factors, search engines show your page top of the SERP when users type a related query that matches your content. Some other important ranking factors that help your content quickly appear in SERPs are your web page loading speed, site authority, content relevancy, quality backlinks, and mobile-friendly content.

Note: Google always updates its ranking system and algorithms, so you should stay updated and work according to the new updates to rank effectively.
