Lazy loading is a strategy often brought up when discussing how to optimize pictures on a website. So what is Lazy loading, and how might it help your site rank higher in search engines? This post will explain how Lazy loadingworks and what it means for SEO.

What does Lazy Loading Mean?

A technique called "Lazy loading" is used to speed up a website by delaying loading large items like photos that aren't needed immediately. These components are instead loaded asynchronously when they are needed.

Users are asked to download and display the whole page when they go to a certain page on your site. It lets the browser save whatever it finds, but it doesn't mean the user will see everything.

No one can say that people will stay long enough to look at every page when a page loads normally, the viewer may only watch for a few seconds before clicking away. So, even if the user never saw it, the content at the bottom of your page took up unnecessary space and time to load.

With Lazy loading, your website can load bits at a time as the user interacts with it. Your page will only load the top half, leaving a blank space below. As a visitor scrolls down your website, the blank spaces are filled with the right information.

You don't have to show all of your content right away. Instead, you can use Lazy loading. They won't waste time waiting for your site to finish loading before they can get the information they need. Your page's content only loads when it needs to.

Using this method to load your site will make it take less time to load. When a website loads too long, more visitors leave without staying. Search engine optimization suffers when many people visit a site but don't click on anything.

How does Lazy Loading Affect SEO?

Lazy loading appears to be the best option to help your pages load quickly at first glance. Your site's visitors will appreciate how rapidly the pages load and can start perusing the content you've provided. While attempting SEO optimization, however, complications arise.

There is a correlation between Lazy loading and decreased crawl rates. Search engines can't index your site if it takes too long to load. This means others are less likely to pay attention to or perceive your words correctly.

Search engines must find everything on your site, as it can significantly impact how well your page performs in the search results. It affects your keyword rankings and causes your page to not rank well for specific keywords.

Nonetheless, this does not preclude the usage of slow loading. To get the most out of Lazy loading, you should always ensure that all necessary material is presented in the viewport. Using the IntersectionObserver API and a polyfill will do this and guarantee that Google's bots will be able to access all of your site's content during a crawl.

Furthermore, if you use infinite scroll, your pages should be able to load new ones in a paginated fashion. Sharing your material will become easier for your audience, and Google can provide in-content connections rather than just connecting to the top of infinite scrolling pages.
