Interstitials are full-page ads that appear between two content pages on a website. In the context of SEO, interstitials can negatively impact user experience and search rankings if they disrupt the user’s ability to access the desired content. Google has guidelines in place that penalize websites that use intrusive interstitials.


Interstitials refer to advertisements or messages that appear in between two content pages or during transitions on a website or app. These can include pop-up windows, full-page overlays, or banners that interrupt the user experience and take up the entire screen. While interstitials can be an effective way for marketers to grab the user’s attention, they can also be seen as intrusive and disrupt the flow of content consumption for the visitor.

In the context of SEO, interstitials can have a negative impact on a website’s rankings on search engine results pages. Google, for example, penalizes websites that use intrusive interstitials that make it difficult for users to access the content they are looking for. This is because search engines prioritize user experience and aim to provide the most relevant and user-friendly websites to their users. Therefore, it is important for website owners to carefully consider the use of interstitials and ensure they do not hinder the user experience or risk being penalized by search engines.


1. Scenario: A user is browsing an e-commerce website on their mobile device and clicks on a product category to explore further. Instead of being taken directly to the products page, an interstitial pops up prompting the user to sign up for a newsletter before proceeding. The interstitial blocks the content the user is trying to access, causing frustration and potentially leading to a high bounce rate as users navigate away from the site.

2. Case Study: A travel booking website implements interstitials promoting special deals and discounts to visitors when they first land on the site. While the interstitials successfully catch the attention of users and drive click-through rates, the website’s overall rankings start to drop over time. This is because Google penalizes sites that prioritize interstitials over main content, resulting in a decrease in organic traffic and visibility. The travel booking website eventually removes the interstitials and experiences a gradual improvement in search engine rankings.

Best practices

Interstitials are full-screen overlays that appear before or after the expected content on a webpage. While interstitials can be effective for capturing leads or promoting offers, they can also have a negative impact on SEO if not implemented correctly. When using interstitials on your website, it’s important to follow Google’s guidelines to avoid penalties. For example, Google recommends using interstitials responsibly, ensuring that they do not disrupt the user’s experience by being difficult to dismiss or covering a significant portion of the page content. Additionally, it’s important to make sure that interstitials are mobile-friendly, as Google penalizes websites with intrusive interstitials on mobile devices.

To optimize your SEO efforts in relation to interstitials, consider using them strategically to enhance user experience rather than detract from it. For example, use interstitials to offer valuable content or promotions that are relevant to the user’s visit to the page. You can also experiment with different types of interstitials, such as exit-intent popups or slide-ins, to see which ones perform best without negatively impacting your SEO. Finally, monitor the performance of interstitials using analytics tools to track metrics such as conversion rates and bounce rates, and adjust your strategy accordingly to maximize the impact of your interstitials on both user experience and SEO.
