Pop-ups are ads that appear between two content web pages, rather than within a page.

Find out how to block pop-up windows and handle persistent ads on your iPhone, iPad, iPod touch or Mac.

Pop-ups can be ads, notices, offers or alerts that open in your current browser window, in a new window or in another tab. Some pop-ups are third-party ads that use phishing tactics – such as warnings or prizes – to trick you into believing they’re from Apple or another trusted company, so you’ll share personal or financial information. Or they may claim to offer free downloads, software updates or plug-ins to try to trick you into installing unwanted software.  

Unless you’re confident of an ad’s legitimacy, you should avoid interacting with pop-ups or web pages that seem to take over your screen. Here are some additional tips that may help you manage pop-ups and other unwanted interruptions.

Always make sure you've installed the latest software updates for all of your Apple products. Many software releases have important security updates and may include improvements that help to control pop-ups.

The safest place to download apps for your Mac is the App Store. If you need third-party software for your Mac and it isn’t available in the App Store, get it directly from the developer or another reliable source, rather than through an ad or link.

Make sure Safari security settings are turned on, particularly Block Pop-ups – for pop-up windows – and the Fraudulent Website Warning.

On your iPhone, iPad or iPod touch, go to Settings > Safari and turn on Block Pop-ups and Fraudulent Website Warning.

On your Mac, you can find these options in Safari > Preferences. The Websites tab includes options to block some or all pop-up windows, and you can turn on fraudulent site warnings in the Security tab.

If you see an annoying pop-up ad in Safari, you can go to the Search field and enter a new URL or search term to browse to a new site. If you can’t see the Search field on your iPhone, iPad or iPod touch, tap the top of the screen to make it appear.

Some pop-ups and ads have fake buttons that resemble the close button, so take care if you're trying to close a pop-up or ad. If you're unsure, avoid interacting with the pop-up or ad and close the Safari window or tab.

On your Mac, you can also update your settings to prevent windows from opening again after you've closed Safari, or just press and hold the Shift key when you open Safari.

If you see pop-ups on your Mac that just won’t go away, you may have inadvertently downloaded and installed adware (advertising-supported software) or other unwanted software. Certain third-party download sites may include programs that you don’t want with the software that you install.

If you think you may have malware or adware on your Mac, update to the latest version of macOS. If your Mac is already running the latest version, restart it. macOS includes a built-in tool that removes known malware when you restart your Mac.

Check your Applications folder to see if you have any apps that you don't expect to be there and uninstall them. You can also check the Extensions tab in Safari preferences to check whether you've installed any unnecessary extensions that you'd prefer to turn off. If you continue to see advertising or other unwanted programs on your Mac, contact Apple.

There are many different ways to display adverts in digital. Here are some of the most common options.

A banner advert is a graphic image or animation displayed on a website for advertising purposes. Static banners are in GIF or JPEG format, but banners can also employ rich media such as video, JavaScript, HTML5 and other interactive technologies; these allow the viewer to interact and transact with the banner. Banners are not limited to the space that they occupy; some banners expand on mouse-over or when clicked. Some can capture data within the banner.

Google AdWords offers a rich media banner advert builder. You can find it in the ‘Ads’ tab in the AdWords account interface.

There are standard sizes (measured in pixels) for static, animated and rich media banner adverts. Creating banners in these sizes means the ads can be placed on many websites; advertisers sell space in these sizes as well. And here, size (both dimensions and file size) does matter, you can expect varying rates of clickthroughs and conversions across the range of sizes. Bigger is usually better, but if you want to know what works best for your brand, test.

Start with the most common banner size.

Banner sizes available on the Google Display Network include (all sizes are in pixels, Width × Height):

  • Banner (468 × 60)
  • Mobile leaderboard (300 × 50)
  • Leaderboard (728 × 90)
  • Small square (200 × 200)
  • Skyscraper (120 × 600)
  • Wide skyscraper (160 × 600)
  • Square (250 × 250)
  • Medium rectangle (300 × 250)
  • Large rectangle (336 × 280).

Banners may be animated, static or Flash, but must be under 150k in file size.

All adverts need to be supplied with a destination URL. Some rich media adverts allow for multiple destination URLs.

Interstitial banners are banners shown between pages on a website or, more often, between screens on an app. As you click from one page to another, you are shown this advert before the next page is displayed. Sometimes the advert can be closed.

As of 10 January 2017, Google may rank sites lower if they use pop-ups and interstitial ads, since users tend to dislike those ads. This should reduce the number of advertisers using these ad types over time.

As the name suggests, these are adverts that pop up, or under, the web page being viewed. They open in a new, smaller window. You will see a pop-up straight away, but will probably become aware of a pop-under only after you close your browser window.

These were very prominent in the early days of online advertising, but audience annoyance means that there are now ‘pop-up blockers’ built into most good web browsers. This can be problematic as sometimes a website will legitimately use a pop-up to display information to the user. Pop-ups still occur now and then on mobile phones or when visiting somewhat unethical sites.

This advert appears in a layer over the content, but is not in a separate window. Usually, the user can close this advert. In fact, best practice dictates that a prominent close button should be included on the advert, usually in the top right hand corner. Floating adverts are created with DHTML or Flash, and float in a layer above a site’s content for a few seconds. Often, the animation ends by disappearing into a banner advert on the page. Many sites these days are using pop-ups to encourage newsletter signups or social media likes rather than to advertise products.

Remember: your goal is to inform and motivate customers, not annoy them. Floating ads should be engaging and easy to close.

This advert changes the background of the web page being viewed. It is sometimes possible to click on an advert of this type, but not always. The effect of these adverts is difficult to measure as there is often no clickthrough, and its chief purpose is branding.

This is advertising placed on an online map, such as Google Maps. This type of advert is ideal for local businesses and is usually based on keyword searches for the brand’s offering.

Native content advertising is the online version of Advertorials. This is where the advertiser produces content that is in line with the editorial style of the site, but is sponsored or in some way product endorsed by the brand; video is an increasingly popular method of native advertising. Great examples of this exist on Buzzfeed.com. More on this later in the Native advertising section.

Sponsored content advertising exists at the bottom of articles you read online. This is where the ‘suggested articles’ posts appear and in most cases, this is paid-for promotion. Advertisers pay to have their content promoted under certain categories of sites or articles.
