How Search Engines Work & What Are Search Engine Ranking Factors

The internet is incredibly large; there are (currently) approximately 50 billion indexed web pages and without search engines it would be impossible to find useful information in this clutter. It would be like searching for a needle in a haystack.Search engines bring order to this chaos. By building an index they can show you the most relevant web pages for your search query. But this index changes frequently. New websites are added daily, web pages are redesigned, new files are uploaded, etc. Because the internet is a dynamic entity, search engines need a tool to help the index stay up to date. For Digital Marketing Agency Check Vivid Digital 

That’s where crawlers come into play. These automated robots scrape web pages for information; they index links, images, videos and other files.

Here’s how a search engine uses crawlers to create search engine result pages:

A] Discovery:

The crawler finds your website, either via a link from another website or via the Add URL page. Currently, Google only follows href and src links.

B] Indexing:

The web pages are processed and indexed. Note that not all content types can be indexed (e.g. some rich media types or dynamic pages).

C] Results:

When you enter a query, search engines analyze their index and show you the most relevant web pages.

In order to show you the most relevant results from their index, search engines need to use a ranking system. There are several factors that are taken into consideration and understanding these factors is essential for your SEO success.

Search Engine Ranking Factors

Relevancy is determined by over 200 factors. It’s impossible to discuss them all, partially because it would take too much time, but mostly because we don’t know all of them. However, research has identified several elements that are important:

Links

When we talk about links, we talk about PageRank; the link analysis algorithm used by Google. It was made by Larry Page (hence the name PageRank) and Sergei Brin, the company’s founders.This algorithm takes quantities of links into account – every link to a website is seen as a vote for that website. The more links you get, the higher you will rank. SEO Services in Hyderabad visit here

One thing you should keep in mind is that this is not a democratic system. Not every link has the same weight. Links from authoritative websites have more influence than links from less popular websites.

Keywords

The keyword distribution on your page is also important. Google checks how often the search query can be found on your page. If it appears in your domain, url, title, header tags, content… the page will be considered more relevant.

Site Age

Old is gold. Google considers older websites to be more authoritative than new websites.

Freshness

Frequently updating your website is a good idea. Add new pages or update old ones. Fresh pages are a sign that the website is not dead.

Other Factors

As they’ve said before: it’s impossible to discuss all the ranking factors. There are others, such as site speed, AuthorRank, site structure… but these are some of the most important.
