If you're worried your full-screen Alia popup is hurting your Google rankings, use this guide to understand what Google says, check whether your store is affected, and lower the risk without giving up your signups.
Issue
You see one or more of the following:
An agency, SEO consultant, or developer has told you full-screen popups hurt SEO.
You've read that Google penalizes "intrusive interstitials."
Google Search Console sent you a message about intrusive interstitials.
You're considering switching to a smaller popup for SEO reasons.
Environment
Alia campaigns that use a full-screen popup.
Most relevant on mobile, and for visitors arriving from Google search results.
Resolution
Understand what Google looks for
Google asks sites to avoid popups that block visitors from seeing the page's content, especially right when a visitor arrives from search. Google doesn't treat this as a single penalty. It's one part of how Google assesses page experience, and it's weighed per page. How relevant your content is to the search matters far more.
Alia popups overlay your page instead of sending visitors to a separate page, so your page content stays in place underneath and Google can still read it.
Check whether your rankings have changed
Open Google Search Console and go to Performance.
Compare clicks, impressions, and average position for your key pages before and after your popup went live. Use the same length of time for each period, and account for seasonal changes.
Check your Search Console messages for a notice about intrusive interstitials.
If your search traffic is steady and there's no notice, your popup isn't measurably affecting your rankings.
Make your popup easy to close
Keep the close button clearly visible, especially on mobile. Visitors who can dismiss your popup quickly get to your content quickly, which is what Google's guidance is about.
Test full-screen against a smaller popup
If you're still deciding, run an A/B test between your full-screen popup and a non-full-screen version. To build the non-full-screen version, see Creating a Non-Fullscreen mobile Popup and Creating a Non-Fullscreen Desktop Popup. Compare signup rate, bounce rate, and site conversion rate. Most brands find full-screen popups collect noticeably more signups without a meaningful change in bounce or conversion rate.
If you've already switched to a smaller popup and want to go back to full-screen, see Turning a Non-Fullscreen Popup into a Fullscreen Popup on Mobile or on Desktop.
If you want to reduce risk further
Use a time delay so your popup doesn't open the instant a visitor lands. A delay doesn't guarantee Google won't treat your popup as intrusive, but it lets visitors see your page first.
Because Google's guidance focuses most on mobile, you can also make only your mobile layout non-full-screen and keep your desktop popup full-screen. See Creating a Non-Fullscreen mobile Popup.
Cause
Google's guidance discourages popups that cover a page's content, and many SEO checklists summarize this as "full-screen popups hurt SEO." In practice, Google weighs page experience alongside many other factors, and relevance matters most.
FAQ
Will Google penalize my store for a full-screen popup?
Google doesn't publish a specific penalty or threshold. Its guidance discourages popups that block content, but this is one of many factors and is assessed page by page. Checking your Search Console data is the most reliable way to see whether your store is affected.
Does a time delay make my popup SEO-safe?
Not guaranteed. A time delay means visitors see your page before the popup opens, which helps, but Google doesn't say any specific delay is safe.
Is my popup also affecting my site speed?
