Google Core Web Vitals Report Changes: FID and INP
Time to read: 8 minutes

Google’s Core Web Vitals Reports, a search console tool that gives key insights into website performance, are set to change in 2024. The ‘First Input Delay’ (FID) metric will be replaced by a new measurement called Interaction to Next Paint (INP).

Here’s what that means, how it will impact your reports and website performance, and what you can do about it. Spoiler: if you’re a client at Excite Media, we’re all over it — you can sit back and relax.

Google’s Core Web Vitals reports are a significant part of Google Search Console.

If you’re wondering what Google Search Console is, it’s a tool that gives valuable insights into your website’s organic search engine performance. It shows you performance statistics, indexing status (how well you’re geared to show up on the search engine results) and can flag technical issues related to a website’s organic search performance.

Google’s Core Web Vitals is a section within Google Search Console that reports on your website’s performance across some core factors of user experience.

The Core Web Vitals report helps you see how your website pages perform in real-world usage.

They focus on three key areas of User Experience:

Why are Core Web Vitals important? ✏️


The metrics in the core web vitals reports are for things that Google considers essential in evaluating your website’s overall user experience. And, of course, anything that Google deems important for website performance is important to pay attention to — if you want to be shown when people search for what you offer on Google.

Google favours websites with a good user experience. The Core Web Vitals Report section in Google Search Console tells you how you’re doing for user experience. Do well across these, and you’ll do better in organic search.

For business

The Core Web Vitals report is designed to give you actionable information that can help you to enhance your site’s usability, which improves the experience of people visiting your website. It also increases your visitor engagement on the site (or, rather, prevents this from dropping due to poor UX).

Paying attention to the results in your Core Web Vitals report is good for business in general, as it tells you about the experience of your website visitors and how to improve it. A frustrating website experience can make people abandon your website and move on to faster-loading pastures.

Overall, optimising your performance on metrics reported on within the Core Web Vitals reports within Google Search Console can:

Times are a-changin’ 🕖

Now we’ve covered the backstory, let’s talk about the upcoming changes to these reports, and what these changes mean.

Come 2024, Google will replace the current metric, First Input Delay (FID), with a new measurement called Interaction to Next Paint (INP).

What’s First Input Delay (FID)?

We’re so glad you asked, friend. First Input Delay is a measurement of the delay between the user’s first interaction on the website and the time it takes for the website to respond. If you’re a website user, it measures the time it takes (on average) for the website to react after you click a button, or a link, press play on a video, or tap on a dropdown menu. The shorter the delay, the more ‘responsive’ the website seems.

Why Is/Was First Input Delay (FID) Important?

Quite simply, if a website takes too long to respond after you “tell it to do the thing” as a user, it’s a terrible experience, and you’re more likely to leave — either out of frustration or because you think it’s actually not working.

Think of a website like an elevator for a moment. You press the button to bring it to your level, but nothing happens for a few seconds — the doors don’t open, and the button doesn’t light up. You start to wonder if you pressed the button right or if this elevator might be out of order. You might walk away, you might take the stairs, or you might continue to wait. Either way, it’s not a great experience. You tend to trust your safety in said elevator much more if it responds immediately in some way.

Now imagine that the elevator is the main entry point into a certain store, or the easiest way to find out information about the store and if it has what you’re looking for. Because that’s what a website is for many businesses.

On the internet, just like in an elevator, people are impatient. If a website doesn’t respond quickly, users might think it’s broken or may just get frustrated and leave.

If it’s an e-commerce site, they may even be less likely to trust a website with their credit card details if it’s slow to respond to a basic click. (Much like an elevator that seems to be really struggling to make it to your level in the building). It comes across as budget, broken, or unprofessional.

That’s why a low FID is crucial:

What is Interaction to Next Paint?

Interaction to Next Paint (INP) is similar to First Input Delay (FID) but is much more comprehensive.

Interaction to Next Paint is a performance metric on the responsiveness of a webpage to user interactions. It measures the time it takes from when a user interacts with the webpage (like a link click or button click) to when a visible response happens on the webpage. It’s the time it takes for something to visibly happen as a result.

In our elevator example, think of it as the time before the light on the elevator button appears, but not necessarily when the elevator actually arrives.

A good INP score means that the webpage quickly responds to something the user does, and is very similar to FID in this way.

So what’s the difference between the two? And Why is INP replacing FID?

FID focuses on the delay between the user’s first interaction and the time it takes for the website to respond, but it doesn’t measure the delay between that interaction and when the visual feedback appears on the screen. This is where the INP comes in. It measures when there’s a visual reaction on the webpage.

A good INP score implies a quicker visual response after a user interaction, which ultimately leads to a better user experience.

Another key difference between INP and FID is that First Input Delay only measures the delay from the first interaction on a webpage. The Interaction to Next Paint measures the delay in a visual reaction to any interaction.

So, in short, the Interaction to Next Paint is a more accurate measure of your website responsiveness, and the user experience.

How will the FID vs INP change affect you, and what do you do about it? 🤔

What these changes mean to you, the website owner, is that website responsiveness will be measured more accurately with these metric changes. It means that you will need to ensure that your website responsiveness is on-point, and across the entire experience (not just the first interaction on each page) if you want to rank the best you can on Google search.

So, in short, you want to make sure that your website doesn’t take too long to respond to any user interaction. In general terms, it means you need to make sure that your site speed is good, and that nothing is slowing your website down to slow down its response time to an interaction.

On a practical side, it also means that your reports will show the INP metric rather than FID. It’s a good idea to start reporting on INP as early as possible so that you have the comparative metrics when FID is completely phased out.

How do you optimise for Interaction to Next Paint? 📝

Firstly, you’ll want to make sure that your INP score is within the ideal benchmarks.

The measurement is made in milliseconds, tracking the time from a user’s interaction to the visual response on the webpage.

Optimising for INP involves reducing delay, and optimising for speed, for example:

It also means you need to ensure that your website can provide quick visual feedback for those more complex interactions, which may take longer.

It means that you need to optimise the response time for every interaction on a page, not just the interactions that are most commonly your website users’ first interactions.

And it also signals that Google is as serious as ever about the importance of User Experience, and you should be too if you want to get the best results you can in Google’s search engine — which is still by far the most widely used search engine globally.

If you’ve got a website that has slow performance, now is a good time to get that website upgrade underway (chat to the good folks here at Excite Media about that).
