Can Cookie Consent Hurt Your Website's SEO?

Cookie consent is necessary, but is it worth compromising your search engine rankings? The good news is that cookie consent does not harm your site’s SEO if done correctly. 

With Google putting the spotlight on page experience, including “intrusive elements that block web content”, it's time to take a closer look. In this article, we'll explore how cookie consent, particularly cookie banners, can impact SEO, and provide tips on how to implement a cookie consent mechanism that complies with privacy laws while also ensuring search engine visibility.

But first, let’s get up to speed on Google’s 2021 algorithm update and why it matters.

Google is the world’s most-used search engine. Any modification to its search algorithm can significantly impact your website’s search performance.

In June 2021, Google released a core algorithm update called "The Page Experience Update" that prioritizes pages with quality page performance. The update introduced Core Web Vitals, a set of metrics that measure real-world user experience for loading performance, interactivity, and visual stability of a page. Therefore, page experience can be more important for visibility in search and the signals for measurement include Core Web Vitals, mobile-friendliness, HTTPS security, and no intrusive interstitials.

While Google still prioritizes pages with quality information, in the case of pages with similar content, it will give preferences to the page with the better page experience. 

From an SEO standpoint, the Page Experience update and it's measuring metrics or “page experience signals” have highlighted the importance of page experience in determining search visibility. This means that in addition to quality content, you should prioritize optimizing for Core Web Vitals, mobile-friendliness, HTTPS security, and avoid intrusive interstitials to improve page experience and potentially improve your site’s search performance.

In particular, intrusive interstitials such as popups or other types of overlays that obscure the main content can negatively impact page experience and therefore search visibility. Google has stated that intrusive interstitials can make content less accessible, and you should avoid them if possible. Instead, you should use alternatives such as banners or inline forms that don't block the main content. However, Google has specifically called out cookie consent banners as an example of an interstitial that would not be affected by this signal.

Therefore, as long as cookie consent banners are implemented responsibly, they shouldn't negatively impact your search rankings. In fact, including a clear and prominent cookie consent banner on your site can actually help you comply with relevant privacy laws and build trust with your users.

Implementing a cookie consent mechanism on your website is essential to comply with privacy laws, but it's important to make sure that it doesn't end up hurting your website's SEO. Here are some tips to help you:
