Not too long ago, an SEO consumer of mine misplaced 82% of desktop natural visitors to their homepage in a single month.
Then, there was one other 97% decline in desktop natural visitors within the second month.
Why?
The consumer launched a cell and desktop pop-up for all United States guests. Towards my recommendation, the consumer hoped the conversions would outweigh the decline in natural visitors.

Here’s a breakdown of the intrusive interstitial and its impression on natural visitors.
The impression of earlier than and after an interstitial on cell and desktop
The homepage pop-up was associated to a promotion and never triggered primarily based on a time delay or scroll.
Right here is an instance of a cell pop-up:


Within the instance above, the pop-up additionally negatively impacts the responsive design.
Right here is the instance on desktop:


Along with the drop in natural visitors, the homepage misplaced 97% of its key phrase rankings on desktop.


And noticed a 96% decline in cell rankings for the homepage.


A lot of the impression was on branded phrases, not directly impacting the discount in PPC branded spend.
It additionally negatively impacted our web page expertise and web page velocity.
The web site additionally noticed a 10-second decline in web page velocity.
Earlier than the launch of the pop-up, the web site averaged a 3-second load time.


And a 13-second load time after the launch of the pop-up.


You’ll be able to see the adverse impression throughout web page expertise with the pop-up with a lot of structure shifts.


The homepage noticed a 97% decline in natural visitors value worth total.
There isn’t any interstitial penalty or handbook motion
The intrusive interstitial results rankings, not indexing.
Nevertheless, different areas of impression might happen, reminiscent of comfortable 404 errors, server velocity and the positioning’s total web page expertise.
Bear in mind, Google crawls from the U.S., so if these overlays are solely current in European international locations, Google is not going to detect them.
The adverse impression of interstitials is a demotion in search
When Google rolled out the Google mobile interstitial penalty on Jan. 10, 2017, it had a surprisingly quiet impression. A couple of days later, search engine optimization professionals began seeing pages lose 10 or extra positions in rankings.
When the Google page experience hit desktop sites in February 2022, intrusive interstitials had been included as a sign.
It’s necessary to keep in mind that interstitials do not require manual action (not less than not but), however they nonetheless negatively impression your web page expertise.
Google’s John Mueller stated in an SEO Office Hours on Jan. 22, 2021:
- “That is type of like one thing the place we’d barely demote the web site in search. Typically, the tough half is these slight demotions. It’s not the case that we’ll take away the positioning from search or transfer it to web page 100. But when it’s related content material, we should still present it on the primary web page of the search outcomes, simply not as extremely as doable.”

4 examples of unhealthy interstitials
1. Checking to see in case you’re a spammy bot is unhealthy
Gary Illyes from Google posted on LinkedIn, mentioning:
- “Checking if the positioning connection is safe interstitials you see on some websites, a few of the time, is the final search-friendly factor you are able to do.”
Instance:


Briefly, there are different methods to keep away from spammy bots from hitting your web site.
If you happen to detect a bot, Mueller beneficial serving a 5xx status code to manage the robot detection interstitial.
If you happen to run a internet hosting service and have a “you is likely to be a bot” interstitial, ensure it makes use of a non-200 HTTP consequence code (maybe 503) and that it doesn’t have a noindex on it. Serving a noindex+200 will lead to pages being dropped from search, if search engines like google see it. pic.twitter.com/LFGQcq2dzf

2. Redirect to interstitial web page
If you happen to present a consumer web page A within the SERPs however redirect it to web page B after the clicking and web page B features a pop-up or interstitial web page, search engines like google is not going to detect content material exterior the redirected web page.
3. Solely shows interstitial

1. Displaying a cookies coverage interstitial
Authorized interstitials are OK, simply so long as search engines like google can index the content material with out doing something particular, like asking search engines like google to click on on one thing to load the background content material.
This implies GDPR and cookie insurance policies are high-quality.
Right here is an instance of a cookies coverage constructed with a pop-up window:


Right here is one other instance of a cookies coverage constructed with a banner on the backside (my most popular methodology):


Mueller talked about in Google Webmaster Workplace Hours that Google is attempting to acknowledge these authorized banners as separate from promoting banners.
2. Requesting age verification
Age verification classifies as a authorized pop-up, so there are not any points with these.
Right here is an instance of an age pop-up completed properly:


3. Leveraging banners on the high and backside
Right here is an instance of Samsung’s promotional advert banner:


4. Exit intent pop-ups which are time or scroll-based
If you happen to’re going to launch a pop-up, I like to recommend utilizing an exit intent pop-up primarily based on time on the web page (20 seconds or extra) or scroll depth.
Keep tuned for extra updates on the restoration of the interstitial pop-up
