In an ever-evolving digital landscape, the user experience is paramount, and website performance plays a pivotal role in shaping that experience. Recognizing this, Google introduced Core Web Vitals as a set of essential metrics that measure the speed and overall user-friendliness of websites. One key component of Core Web Vitals metrics is the Intrusive Interstitials Policy (INP), which focuses on improving the accessibility and engagement of web content. This article delves into the world of INP and how it’s set to enhance the web user experience.

Understanding Core Web Vitals

Before we dive into INP, let’s establish a broader understanding of Core Web Vitals. These vitals are a set of specific factors that Google considers crucial in assessing the overall user experience of a web page. As of May 2021, Core Web Vitals metrics consist of three key metrics:

1. Largest Contentful Paint (LCP): This metric measures loading performance and evaluates how quickly the largest content element on a page becomes visible. It’s a crucial factor in determining perceived loading speed.
2. First Input Delay (FID): FID focuses on interactivity and gauges the time it takes for a web page to respond to a user’s first interaction, such as clicking a link or button. A low FID score indicates a more responsive website.
3. Cumulative Layout Shift (CLS): CLS assesses visual stability by measuring unexpected layout shifts during page loading. A lower CLS score indicates a more stable and user-friendly experience.

These Core Web Vitals metrics help website owners and developers identify areas of improvement to create faster, more engaging, and more stable web pages.

The Role of Intrusive Interstitials Policy (INP)

While Core Web Vitals primarily deal with loading performance and interactivity, the Intrusive Interstitials Policy (INP) focuses on how web content is presented to users, particularly when they navigate from search results to a web page. Google introduced INP as an initiative to ensure that users have a seamless transition from the search engine results page (SERP) to the web page they intend to visit.

What Are Intrusive Interstitials?

Intrusive interstitials are elements that partially or entirely cover the main content of a web page and disrupt the user experience, especially when accessed from a search engine’s results. These elements often include pop-ups, overlays, and interstitial ads that obscure the primary content.

Google’s Guidelines for Intrusive Interstitials

To improve the user experience and align with Core Web Vitals, Google has established guidelines for intrusive interstitials. According to these guidelines, websites should avoid using interstitials that:

1. Cover the main content: Interstitials that entirely cover the main content, making it inaccessible or challenging to reach, should be avoided.
2. Display immediately: Interstitials that appear immediately after a user navigates to a page from a search result should be used sparingly or not at all. Users should have the opportunity to engage with the main content without interruption.
3. Force interactions: Interstitials that require user interactions before they can be dismissed or closed should be minimized. Users should not feel compelled to take action to access the main content.

Why INP Matters for Web User Experience

INP is significant for several reasons, all of which revolve around improving the web user experience:

1. Reduces User Frustration: Intrusive interstitials can be frustrating for users, especially when they obstruct the main content. By minimizing or eliminating these disruptions, web pages become more user-friendly.
2. Aligns with Core Web Vitals: INP complements other Core Web Vitals metrics by ensuring that web pages are not only fast and interactive but also free from intrusive elements that hinder user engagement.
3. Enhances Accessibility: Making web content easily accessible to users is a fundamental aspect of web design and development. INP encourages developers to prioritize content accessibility, benefiting users with disabilities or those using assistive technologies.
4. Improves SEO Rankings: Google takes web user experience seriously and uses various metrics, including Core Web Vitals and INP, as ranking factors. Websites that prioritize these metrics are likely to perform better in search engine results, driving more organic traffic.

How to Comply with INP Guidelines

To ensure your website complies with Google’s INP guidelines and provides an optimal user experience, consider the following best practices:

1. Minimize Intrusive Interstitials: Review your website for intrusive interstitials and minimize their use. If you must use them, make sure they do not disrupt the user experience or obstruct the main content.
2. Prioritize Content Accessibility: Ensure that your web content is accessible to all users, including those with disabilities. Follow established accessibility guidelines, such as the Web Content Accessibility Guidelines (WCAG).
3. Use Non-Intrusive Banners: If you need to display banners or notifications, opt for non-intrusive designs that do not obstruct the main content. Consider using banners that can be easily dismissed or minimized.
4. Test on Mobile Devices: Given the prevalence of mobile browsing, it’s essential to test your website’s INP compliance on various mobile devices and screen sizes.
5. Stay Informed: Keep up to date with Google’s guidelines and updates related to INP and Core Web Vitals. Periodically review your website for compliance and make necessary adjustments.

In conclusion, Google’s Intrusive Interstitials Policy (INP) is an integral part of Core Web Vitals, emphasizing the importance of a seamless user experience from search results to web pages. By adhering to INP guidelines and prioritizing non-intrusive content presentation, website owners and developers can enhance their websites’ accessibility, user-friendliness, and search engine rankings, ultimately providing a more satisfying experience for users in the digital realm.
