Website Indexing for Search Engines: How Does It Work?

Indexing websites is one of the first steps (after crawling) in a complex process of understanding what web pages are for in order for them to be listed and served as search results by search engines.

Search engines are constantly improving how they crawl and index websites.

Understanding how Google and Bing crawl and index websites is essential for technical SEO and useful in developing strategies for improving search visibility.

This article focuses on indexing. So let’s dive in.

Web Indexing

Indexing is where the ranking process begins after a website is crawled. This may interest you : The State of Search Engine Optimization in 2022: Statistics and Trends You Need to Know [infographic].

Indexing essentially refers to adding web page content to Google to be considered for rankings.

When you create a new page on your website, there are several ways it can be indexed.

The simplest method of indexing a page is to do nothing at all.

Google has crawlers following links, so as long as your site is already in the index, and the new content is linked to your site, Google will eventually find it and add it to its index . More on this later.

How To Get A Page Indexed Faster

But what if you want Googlebot to reach your page faster? Read also : Content marketing experts share how to improve your writing and SEO.

This can be important if you have timely content or if you’ve made an important change to a page that Google needs to know about.

I use faster methods when I’ve optimized a critical page or tweaked the title and description to improve click-through.

I want to know specifically when they were picked up and displayed in the SERPs to know where the improvement measure starts.

In these cases, there are a few additional methods you can use.

1. XML Sitemaps

XML sitemaps are the oldest and most reliable way to call search engine attention to content.

An XML sitemap gives search engines a list of all the pages on your site, as well as additional details about it, such as when it was last modified.

A sitemap can be submitted to Bing through Bing Webmaster Tools, and can also be submitted to Google through Search Console.

But when you need an indexed page right away, it’s not particularly reliable.

2. Request Indexing With Google Search Console

In Search Console, you can “Request Indexing.”

You start by clicking on the top search field, which by default reads, “Inspect and URL in domain.com.”

Enter the URL you want indexed, then press Enter.

If the page is already known to Google, you will be presented with a lot of information. We won’t go into that here, but I recommend logging in and seeing what’s there if you haven’t already.

For our purposes here, the important button appears whether the page is indexed or not – meaning it’s good for content discovery or just asking Google to understand a recent change.

You will see the button shown below.

Within a few seconds to a few minutes, you can search the new content or URL in Google and find the change or new content that was raised.

3. Participate In Bing’s IndexNow

Bing has an open protocol based push method of alerting search engines about new or updated content.

This new search engine indexing protocol is called IndexNow.

It’s called a push protocol because the idea is to alert search engines using IndexNow about new or updated content, which will cause them to index it.

An example of a pull protocol is the old XML sitemap way that relies on a search engine crawler to decide to visit and index it (or to be fetched by Search Console).

The advantage of IndexNow is that it wastes less web hosting and data center resources, which is not only more environmentally friendly but saves on bandwidth resources.

The biggest advantage, however, is faster content indexing.

Currently only Bing and Yandex use IndexNow.

4. Bing Webmaster Tools

In addition to participating in IndexNow, consider a Bing Webmaster Tools account.

If you don’t have a Bing Webmaster Tools account, I can’t recommend it enough.

The information provided is significant and will help you better assess problem areas and improve your rankings on Bing, Google, and elsewhere – and most likely provide a better user experience.

But to get your content indexed, all you need to do is click: Configure My Website > Submit URLs.

Enter the URL(s) you want indexed and click “Submit.”

So, that’s most of what you need to know about indexing and how search engines do it (with an eye on where things are going).

More details on the Bing Webmaster Tools URL Submission Tool help page.

There is also the Bing Webmaster Tools Indexing API which can also speed up the time content appears in Bing search results within hours.

More information about the Bing Indexing API is here.

Crawl Budget

We can’t talk about indexing without talking about the crawling budget.

Basically, crawl budget is a term used to describe the amount of resources Google will spend on crawling a website.

The allocated budget is based on a combination of factors, the two central ones being:

If you run a large news site with constantly updating content that search engine users will want to be aware of, your site will be crawled frequently (dare I say – constantly).

If you run a small barbershop, you have two dozen links, and you are rightfully not considered important in this context (you might be an important barber in the area , but you are not important in terms of the crawl budget), then the budget will be low.

You can read more about crawl budgets and how they are determined in Google’s explanation.

Discover How Search Engines Work

Optimizing websites for search engines starts with good content and ends with sending it to be indexed.

Whether you do it with an XML sitemap, Google Search Console URL Submission Tool, Bing Webmaster Tools, or IndexNow, getting that content indexed is when your web page starts its journey to the top the search results (if everything works out!).

That’s why it’s important to understand how search indexing works.
