What is Intrusive Interstitial Penalty

In today’s digital landscape, where user experience plays a crucial role in website success, webmasters and marketers must be mindful of the intrusive interstitial penalty enforced by search engines. The intrusive interstitial penalty aims to discourage the use of intrusive interstitials, which can negatively impact user experience and hinder accessibility. This article explores what the intrusive interstitial penalty entails, its implications, and best practices for compliance.


When users visit a website, they expect a seamless and enjoyable browsing experience. However, intrusive interstitials, such as pop-up ads or full-screen overlays, can interrupt users’ interaction with web content, leading to frustration and annoyance. Recognizing the importance of user experience, search engines like Google have implemented measures to penalize websites that employ intrusive interstitials.

Understanding Intrusive Interstitials

Intrusive interstitials are web elements that appear between page loads or when accessing certain parts of a website. These interstitials often cover the main content, requiring users to dismiss them or wait before accessing the desired information. While some interstitials serve legitimate purposes, such as cookie consent notices or age verification screens, many are perceived as disruptive and burdensome.

Impact on User Experience

Frustration and annoyance

Intrusive interstitials can significantly disrupt users’ browsing experience. When confronted with a sudden overlay that obstructs the content they were trying to access, users may become frustrated or annoyed. This negative reaction can undermine the overall perception of a website and decrease the likelihood of user engagement.

Increased bounce rates

An immediate consequence of intrusive interstitials is an increased bounce rate. Users who encounter obstructive overlays may choose to leave the website altogether rather than invest time and effort in navigating through the interstitials to access the desired content. High bounce rates can adversely affect search engine rankings and organic traffic.

Negative impact on mobile usability

Mobile devices have become the primary means of accessing the internet for many users. Intrusive interstitials pose a more significant challenge on mobile screens, where space is limited. Overlays that are not mobile-friendly can impede usability and frustrate users, leading to a poor mobile experience and potential penalties from search engines.

Google’s Intrusive Interstitial Penalty

Recognizing the impact of intrusive interstitials on user experience, Google implemented an algorithmic penalty to discourage their use. This penalty, referred to as the intrusive interstitial penalty, can affect a website’s search engine rankings if it fails to comply with Google’s guidelines regarding interstitial usage.

Definition and purpose

The intrusive interstitial penalty targets interstitials that significantly obstruct a user’s ability to access website content. These penalties are intended to ensure that websites prioritize user experience and provide unfettered access to information without unnecessary interruptions. By penalizing intrusive interstitials, search engines aim to encourage webmasters to adopt user-friendly alternatives.

Algorithmic updates

Google periodically rolls out algorithmic updates that refine its search engine ranking factors. The Mobile Interstitials Penalty, introduced in 2017, specifically focuses on intrusive interstitials displayed on mobile devices. Websites that fail to comply with the guidelines may experience a decline in mobile search visibility and organic traffic.

Types of Intrusive Interstitials

To understand how to comply with the intrusive interstitial guidelines, it is essential to identify the types of interstitials that are considered intrusive.

Pop-up ads

Pop-up ads, which suddenly appear in a separate window, are a common example of intrusive interstitials. These overlays obstruct the main content and require user interaction to dismiss or engage with them.

Full-screen overlays

Full-screen overlays, also known as interstitial ads, cover the entire screen, obscuring the website’s content. They often require users to interact with them before proceeding, hindering seamless access to the desired information.

Welcome mats

Welcome mats are full-screen interstitials that appear immediately after a user arrives on a website. These overlays typically display a message or offer and require users to take action before accessing the main content.

Interstitials that require dismissal

Some interstitials appear in-line with the content but require dismissal before the user can proceed. These interstitials may cover a significant portion of the screen, causing inconvenience and disrupting the user’s flow.

Best Practices for Compliance

To avoid the intrusive interstitial penalty and prioritize user experience, webmasters should adhere to the following best practices:

Use of non-intrusive alternatives

Rather than relying on intrusive interstitials, consider implementing non-intrusive alternatives that provide valuable information or calls to action without obstructing the main content. Non-intrusive alternatives can include banner ads, slide-ins, or inline content suggestions.

Proper implementation of interstitials

If interstitials are necessary for specific purposes, ensure they are implemented correctly. Interstitials should be easily dismissible, not cover the entire screen, and not excessively delay access to the main content.

User-friendly design

Design interstitials with the user in mind. Ensure that they are visually appealing, easily understandable, and compatible with various devices and screen sizes. A user-friendly design can enhance the overall browsing experience and increase engagement.

Examples of Non-Intrusive Alternatives

When implementing interstitials, it is crucial to consider non-intrusive alternatives that maintain a positive user experience. Here are a few examples:

Banner ads

Banner ads are typically displayed at the top or bottom of a webpage, providing relevant information or offers without obstructing the main content. They can be easily ignored or clicked on, allowing users to continue browsing uninterrupted.


Slide-in interstitials appear as a small panel that slides into view from the edge of the screen. They provide additional information or call-to-action options without obscuring the main content. Users can interact with the slide-in or dismiss it if they choose to do so.

Inline content suggestions

Inline content suggestions are interstitials that seamlessly blend with the main content. They appear within the text, suggesting related articles, products, or other relevant information. Inline content suggestions offer value without disrupting the user’s reading experience.

Tips for Effective Interstitial Usage

While intrusive interstitials should generally be avoided, there are scenarios where interstitials can still be effective if used correctly. Consider the following tips for optimizing interstitial usage:

Timing and frequency

Timing is crucial when displaying interstitials. Avoid interrupting users immediately upon landing on a page or as they are about to interact with the content. Additionally, limit the frequency of interstitials to prevent overwhelming users with excessive interruptions.

Targeting specific audience segments

Segment your audience and target specific user groups with relevant interstitials. Personalizing the interstitial content based on user preferences and behavior can increase the likelihood of engagement and conversions.

A/B testing and performance monitoring

Continuously evaluate the performance of interstitials through A/B testing. Test different designs, formats, and timings to identify the most effective variations. Monitor user behavior, bounce rates, and conversion rates to make data-driven decisions.

Benefits of Complying with Intrusive Interstitial Guidelines

Complying with intrusive interstitial guidelines can yield several benefits for website owners and users alike.

Enhanced user experience

By avoiding intrusive interstitials, websites can provide a smoother, more enjoyable browsing experience for users. Users will appreciate seamless access to information without constant interruptions, leading to increased engagement and satisfaction.

Improved search engine visibility

Adhering to Google’s guidelines ensures that your website remains in good standing with search engines. Compliance can lead to higher search engine rankings, increased organic visibility, and ultimately more organic traffic.

Higher engagement and conversions

A positive user experience fosters trust and encourages users to engage with your content or take desired actions. By avoiding intrusive interstitials and utilizing non-intrusive alternatives, you can enhance user engagement and increase conversion rates.


The intrusive interstitial penalty is a measure taken by search engines, like Google, to prioritize user experience and discourage the use of intrusive interstitials. By complying with guidelines, webmasters can create websites that offer a seamless and enjoyable browsing experience, leading to improved search engine visibility, user engagement, and conversions.
