Ads on the web

In general, advertisements on the web could be categorized by type and by source.

Types of advertisements

Differentiating by type following advertisement types can be distinguished:

• Banners (special areas inside the web pages where advertisements are placed);
• Pop-up windows (separate browser windows with advertisements popping up without user's leave).

There are several variations of this categorization. In most occasions, there is no need to know them to struggle with ads. The only thing to do to block an ad is to point to it with a mouse and instruct Ad Annihilator to block it (see How to block banners?  for more details).

But in rare occasions it is necessary to understand these subtleties. For example, banners may appear as:

• Pictures that are loaded as regular images using an IMG HTML tag;
• Frame advertisements loaded in IFRAME or FRAME HTML tags;
• Flash advertisements.

Ad Annihilator efficiently fights with each of aforementioned type of advertisements.

Sources of advertisements

Advertisements come either from the same site on which they appear or from another site. We'll refer to them as first-party resources and third-party resources respectively. The latter case is much more frequent and many sites show advertisements from advertiser sites. It is the fact that advertisements usually come from specific advertiser sites that Ad Annihilator is capable of filtering out banners and popups.
