How to Enhance Largest Contentful Paint (LCP) And SEO


New vocabulary is required as the field of user experience metrics evolves. The Largest Contentful Paint (LCP) metric is one of several that measures the time it takes for content on a web page to render. Let’s find out about everything about this metric, and why companies offering web design SEO Services in New York should pay importance to this:

Largest Contentful Paint

LCP is defined by Google as “the render time of the largest visible content element within the viewport.” For the sake of this blog, “content” will be defined as a picture, often a JPEG or PNG file. Most of the time, “largest” refers to a hero image, which is one of the first things users notice when they load the website. Improving LCP necessitates optimizing the most important content. LCP indicates when the time it takes for a web page to load begins to have a significant influence on the user experience. The occurrence of LCP should be within 2.5 seconds of the website loading to provide a good user experience. Anything more than 4 seconds is regarded as substandard.

What Effect Does the Most Contented Paint Have on Lighthouse Scores and SEO?

LCP is now one of the “Core Web Vitals” scores that Google will consider when determining how to rank websites. Each of the Core Web Vitals represents a unique aspect of the user experience, is field quantifiable, and reflects real-world experience with a vital user-centric consequence. LCP indicates a 25% weighting on the performance score of Lighthouse version 6.0 when it comes to the overall Google Lighthouse score. As a result, the LCP measure is the most essential Core Web Vitals statistic for establishing the performance score.

While Google has stated that content is still the most important factor in SEO results, in a competitive market, a better user experience (as evaluated by Core Web Vitals) will result in higher rankings. Largest Contentful Paint will be a crucial factor in rankings if there are numerous websites contending for the top search engine ranks.

How to Make the Largest Contentful Paint Better?

What can you do to enhance LCP by making content load faster now that you know how crucial it is? The most effective strategy, according to Google, is to optimize content for the device that is requesting it.

Using Image Speed Test, you can find savings in the Largest Contentful Paint

Image Speed Test is a fantastic tool provided by ImageEngine.io that analyses LCP optimization options. It also includes a video of the page loading both with and without improvements. Finally, it examines each image to determine how much payload may be saved. This image is the page’s “biggest content” in this scenario. The picture payload is decreased by 94 percent thanks to optimizations.

Best practices


Aside from employing an image CDN like ImageEngine, there are a few additional best practices that might help with LCP. The download process can be sped up by using the resource hints to give a preconnect for your content. Adding the following link statement to the HTML, for example, will speed up the download process. The link statement causes the browser to connect to the third party as soon as feasible, allowing the download to begin faster. ImageEngine’s optimizations reduce the size and speed of each image download, while preconnect saves time during the connection process.

Decrease blockage of JavaScript and CSS

When JavaScript or CSS is “blocking,” it indicates that the browser must parse and execute CSS and JavaScript before painting the page’s final state in the viewport. Because today’s websites rely extensively on both JavaScript and CSS, it’s nearly impossible to avoid some render-blocking resources. On a more general topic, be cautious with the types of CSS and JavaScript that are referenced within the head element. Make sure that only the resources that are absolutely necessary are put into the head. The rest can be loaded asynchronously or postponed.

JavaScript shouldn’t be used to lazy load images

Lazy loading is supported by many modern browsers without the usage of JavaScript. Because pictures are usually prominently engaged with LCP speed, it’s recommended to leave image loading to the browser and avoid using JavaScript to slowly load images.

In all, it’s important to know about the core web vitals, including the one discussed in this post, to be in a better position to rank your website. Of course, hiring reliable services by Map-It Inc. is recommended by you need to expand your knowledge as well to stay abreast of what’s happening in the digital world. The more you know, the better it is for your endeavor.
