Here are some best practices for using interstitials, ways to make the most of them, and common mistakes to avoid. We've also added interesting facts and stats about interstitials.

Best Practices for Using Interstitials

Timing is Everything

The timing of your interstitial is crucial. You don't want to display it too soon, or your visitors may leave your website before seeing your content. Similarly, you don't want to display it too late, or your visitors may have already left. A good rule of thumb is to display your interstitials after your visitors have finished reading an article or viewing a page.

Keep it Short and Sweet

Your interstitial should be displayed for a short time. You don't want to bore your visitors with a lengthy ad that takes forever to load or scroll through. Keep it simple, with a clear message and a call-to-action.

Grab the user's attention even more

Try shocking or very prominent content that catches the eye. Don't overdo it - ads can be fresh and slightly controversial, but don't choose offensive or blunt interstitials.

Also, using a clickbait headline might increase the chances of users clicking on the ad. 

Don't Overdo It

Overusing interstitials can quickly become annoying to your visitors. Limit the number of interstitials you display, and make sure they are relevant to your website's content.

Test, Test, Test

Test different variations of your interstitials to see which ones are more effective. Use analytics to measure the success of each variation, and adjust accordingly.

How to Make the Most of Interstitials

Interstitials can be a great way to promote products, services, or events. You can use them to highlight a sale, offer a discount code, or promote a webinar.

If you offer a free resource or newsletter, use an interstitial to encourage visitors to sign up. Offer an incentive, such as a free guide or ebook, to entice them to subscribe.

Affiliate marketers can use interstitials to link to an affiliate product, increasing the chances of your visitors making a purchase.
