Pop up ads are advertisments that show up in a new browser window. There’s no one standard size for popup ads. Popup ads also vary widely in the amount of browser commands that show in the window.
Pop-up ads are just one form of internet advertising used by advertisers to get web users’ attention. Among these other types of ads are ads located within a page you’re reading, ads that appear when you’re clicking from one page to another (these are called interstitials), ads that appear when you’ve searched for a keyword or term, ads that are highly animated or appear as interactive games, ads that appear like stand alone websites, ads that appear in email, branded sites or sponsored webpages (the advertiser’s brand appears on all pages and the page composition might have been modified to fit the advertiser’s logo or brand colors/layout), paid listing, and many others.
GIF (Graphics Interchange Format) is a type of picture file used on the internet. It has certain special characteristics which make it more useful than JPEG or other picture file formats in certain situations. Clear GIFs are commonly used as web beacons because they are invisible and very small so they don’t affect the download speed of a webpage or email. However any sort of file could be used as a web beacon.
