We’ve all been there. You click on a website, ready to read something interesting, and before you’ve even finished the first sentence, a giant pop-up appears demanding your email address.
You haven’t even decided whether you like the website yet. Give us a minute!
Pop-ups can be brilliant for generating enquiries, promoting offers and growing mailing lists. Get them wrong though, and they could harm your website’s search engine rankings.
Does Google penalise websites for pop-ups?
Not all pop-ups are bad for SEO (search engine optimisation). Google is particularly concerned about what it calls intrusive interstitials. In plain English, these are pop-ups that make it difficult for visitors to access the content they’ve come to see.
For example, imagine searching Google for emergency plumbing advice. You click a result, only to find a full-screen newsletter sign-up blocking the instructions.
Frustrating for visitors, and potentially problematic for Google.
However, a small promotional banner at the bottom of the screen? Generally fine. It’s about making sure the pop-up doesn’t get in the way.
Which pop-ups are safe for SEO?
There are several types of pop-ups that can work perfectly well when implemented correctly.
Email sign-ups
Rather than appearing immediately, these can be triggered after someone has spent time reading your content.
Special offers
An online retailer advertising 10% off someone’s first purchase can use a small, dismissible pop-up without covering the entire page.
Cookie notices
These are often legally necessary, but poorly built cookie banners can slow websites down or cause content to jump around.
Live chat
Chat widgets can help turn visitors into customers, provided they don’t slow down your website.
The important thing is that visitors can still access the information they came for.
It’s not just about rankings
Poorly implemented pop-ups can also affect Google’s Core Web Vitals, which measure aspects of website speed, responsiveness and visual stability. For example, a cookie banner that suddenly pushes half your page down can contribute to layout shifts, or a slow-loading chat widget could affect how quickly someone can interact with your website.
Neither is particularly helpful when you’re trying to impress potential customers.
At Engage Web, we can design and implement pop-ups for our clients that encourage enquiries, promote offers and capture leads without damaging your website’s SEO or performance. We make sure they’re properly implemented, mobile-friendly and don’t get in the way of your visitors. If you want a custom-made pop-up for your website, get in touch with our team to discuss how we can make it work for your business, rather than against it.
