First, let's define some terminology to talk to you in one language. Target visitor – a potential buyer of the goods advertised. Keyword (phrase) – a word or phrase that user uses to find specific information in the search engine. Target audience – a group of people targeted in advertising and promotional activities. The main and most important to the advertiser category of recipients of the advertising reference. serp ("crescent" – a portmanteau. serp – Search Engine Result Page) – issuance of search results for any query, sorted by relevance. Thus, among a wide variety of different types Internet advertising are the following major groups: Media advertising (banner); Contextual advertising; Progress in the search engines (site promotion); Newsletter advertisements.
Other species Internet advertising to some extent will relate to these four groups, or are not sufficiently significant. Just want to say a few words about the last group of advertising and not to return to her. Newsletter ads can be of two types of address when the recipient knowingly agreed to the receipt of this distribution, and mass, better known as spam (sending of advertising on various types of channels of communication without the consent of the recipients). Mailing of, first, occupies a very small market share, and, secondly, often aimed at supporting older audience than attract new. Spam, in turn, is a fully legitimate form of advertising, and therefore do not dwell on it desires. The same group advertising "Newsletter ads" could be considered, which has recently become popular, viral marketing, but rather refers to marketing techniques (tools) than to advertising on the Internet.
And so it is the golden rule of a journalist – before you disclose any information it needs to be checked for reliability. But there is another detail in the organization ISIF, that is for sure and has attracted attention. The fact that the promotion of ISIF is built on the principle of network marketing. Network or multilevel marketing (English network or multilevel marketing) is way to retail sales through direct sales, in which a person became a distributor, receives part of the remuneration of other distributors, which he drew for distribution. Marketing approach, similar to virus: the goods are distributed to friends of friends. It is mainly used in cosmetics. 
An example is the introduction and the Russian Automatic AP50 (in fairness, quite reliable) – black rectangular box with two (red and white) buttons in the lower right corner. Boxed unit take up much space and are forced to increase the size of the shield, so where permissible, use modular instruments. Major recent standardized mounting dimensions (width 17,5-18 mm, depth of the plane inner side of the closing panel to the mounting plane 58 mm, total height is not more than 96 mm, the protruding part with the organs of control and is located in the center) and typically do not vary from manufacturer to manufacturer. Enclosure device is installed horizontally in a row on a special metal profile (35 mm DIN-rail). Thus, they form one single entity, and may close the general panel, which leaves access to controls. The only exceptions are modular circuit breakers in a 60-26 (Tiraspol plant) width 12,5 mm.
