How to Optimize Core Web Vitals for Food Blogs

Last updated on by 2 comments

Google’s 2021 algorithm update will factor in page experience as a ranking signal. This means that if your food blog’s user experience suffers, your ranking in SERPs could drop. There are a number of elements that decide the quality of the page experience. These include core web vitals, responsiveness, safe browsing, and non-intrusive interstitials.

In this article, we’ll explain what core web vitals are and how you can optimize them to enhance your food blog’s user experience.

What Are Core Web Vitals?

In simple terms, core web vitals are policies that enable site owners to deliver enhanced user experiences for mobile users. Google’s Page Experience update will officially roll out sometime in 2021.

There are three core web vitals food blogs should optimize to improve user experience. These are the Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics tell Google:

  • LCP – How fast the page loads.
  • FID – How quickly the page becomes interactive.
  • CLS – How stable the page is.

The good news is that mobile usability is already built into WordPress. All you have to do is make sure you’re using a responsive, SEO-friendly theme (like Foodica) and taking the necessary steps to improve your website’s core web vitals scores.

How to Optimize Core Web Vitals for Your Food Blog

To diagnose and fix user experience issues, you’ll first need a way to measure your core web vitals scores. Google recommends using either Google Search Console, Google PageSpeed Insights, or Google Lighthouse.

Note: core web vitals will be applied on a per-page basis. This means that you need to ensure that all pages within your food blog pass, as well.

Largest Contentful Paint

As the name suggests, LCP is the time it takes for the largest block of content to load on a page. This could be an image, video, or block-level text – whatever occupies the largest portion on the user’s screen. Google does this by looking at the physical size of the element.

Here’s what your LCP score means:

  • Good – Less than or equal to 2.5 seconds.
  • Poor – Between 2.6 seconds to 4.0 seconds.
  • Bad – More than 4.0.

Many different factors can cause slow loading times. These include:

  • Slow server response times
  • Long time for fetching resources
  • JavaScript and CSS blocking render time

To optimize your LCP score, make sure you’re using a good web host for your food blog. In terms of web design, go for a theme that isn’t too crowded.

If, however, you absolutely need to use a feature-rich theme with lots of JavaScript, consider loading the first few content blocks first while the JavaScript loads in the background.

It’s also a good idea to compress images before you upload them to your WordPress site and embed videos from video hosting platforms (like YouTube) instead of hosting them on your own server.

First Input Delay

FID tells Google when interactive elements on your food blog are ready to function. In other words, how fast will your web page respond to an action like entering a search query, clicking a button, or filling out a form. Of course, if there aren’t any user-activated elements on the web page, it won’t be calculated.

Here’s what your FID score means:

  • Good – Less than or equal to 100 milliseconds.
  • Poor – Between 1.1 seconds to 43.0 seconds.
  • Bad – More than 3.0.

The main culprit behind poor FID scores is JavaScript render-blocking. Here’s what happens: when the user’s browsers see JavaScript files that need to be loaded, it automatically pauses all other tasks to run the JavaScript first. The longer it takes for the JavaScript code to run, the higher your FID score.

To improve your FID scores, consider minimizing or deferring JavaScript code. Many WordPress caching solutions can take care of this for you. In addition to this, you should also remove non-critical third-party scripts such as heatmaps from your pages.

Cumulative Layout Shift

Your web page’s CLS has the potential to aggravate visitors the most. You’ve probably experienced this yourself. Here’s what happens: you load a page and try to click a button but another element (like an ad) shows up in its place and you click that instead.

In more technical terms, the element that loaded above the button shifted the page’s layout. So, CLS tells Google how fast your web page becomes stable.

Here’s what your CLS score means:

  • Good – Less than or equal to 0.1
  • Poor – Between 0.1 and 0.25
  • Bad – More than 0.25

Unlike LCP and FID, CLS is a distance measurement. More specifically, Google calculates CLS by multiplying the impact fraction with the distance fraction. It’s also important to mention that Google only calculates unexpected layout shifts. In contrast, expected layout shifts happen when users, say, tap a menu or click a dropdown menu.

The individual CLS values are added to determine the web page’s CLS.

To optimize your food blog’s CLS, you should specify the size dimensions of the images and video elements you’re adding to the page. Similarly, you should reserve spaces on your site for displaying banner ads so they don’t shift other page elements while loading.
