When you get to a website that takes forever to load, how does that make you feel? If you’re like most people then you probably experience an emotion related to anger or frustration.
And when you’re on a website that makes you feel angry or frustrated, do you usually stay on that website? Probably not.
Instead, you’d go to another website.
The people who are researching your products and services online right now are no different. They don’t have the patience to sit around waiting for a slow website to show up on their smartphone or desktop; they want everything immediately. The longer you make them wait, the more interest they lose in you.
Website Load Speed Affects Your SEO
Google started using site speed as a ranking signal in their algorithm way back in 2010, and it continues to serve as one of the many factors that determine where your website shows up in the search results.
Site speed reflects how quickly a website responds to web requests.
Speeding up websites is important—not just to website owners, but to all Internet users. Faster websites create happy users and we’ve seen in our internal studies that when a website responds slowly, visitors spend less time there.
Lazy loading is a technique of delaying the loading of certain resources until after the initial page has been rendered. With fewer render-blocking resources, the first paint of the screen is delivered faster, resulting in a faster experience for the user.
As the user scrolls down the page, resources are loaded in dynamically only when they are needed. Effectively, we are splitting the loading of the page and only ever loading the assets that are needed.
Advantages of website lazy loading:
· Minimizes start-up time of the application
· Application consumes less memory because of on-demand loading
· Unnecessary database SQL execution is avoided
· Unnecessary code execution is avoided
· Optimal usage of time and space resources makes it a cost-effective approach.
Disadvantages of website lazy loading:
First, the extra lines of code, to be added to the existing ones, to implement lazy load makes the code a bit complicated. Second, lazy loading may affect the website’s ranking on search engines sometimes due to improper indexing of the unloaded content.
Though there are certain pitfalls of lazy loading on a website, the big advantages of an optimal utilization of the two major resources of time and space make it a valuable tool.
